Skip test_ractor.rb:137 for --jit-min-calls=5

-	* configure.in (RUBY_DTRACE_POSTPROCESS): dtrace version SUN D 1.11
-	  introduces a check in the dtrace compiler to ensure that probes

-	* lib/irb/output-method.rb: raise right exception when
-	  IRB::OutputMethod#print don't defined [Bug #6657].
+	* ext/openssl/ossl_ocsp.c: Add OCSP::SingleResponse that represents an
+	  OCSP SingleResponse structure. Also add two new methods #responses
+	  and #find_response to OCSP::BasicResponse. A BasicResponse has one or
+	  more SingleResponse. We have OCSP::BasicResponse#status that returns
+	  them as an array of arrays, each containing the content of a
+	  SingleResponse, but this is not useful. When validating an OCSP
+	  response, we need to look into the each SingleResponse and check their
+	  validity but it is not simple. For example, when validating for a
+	  certificate 'cert', the code would be like:
 
-Tue Dec 25 22:06:33 2012  Koichi Sasada  <ko1@atdot.net>
+	    # certid_target is an OpenSSL::OCSP::CertificateId for cert
+	    basic = res.basic

-	* vm_trace.c (rb_threadptr_exec_event_hooks_and_pop_frame):
-	  pop a frame before JUMP_TAG() if exception occurred.
-	  This change fix bug of Ruby 1.9.
-	  [ruby-core:51128] [ruby-trunk - Bug #7624]
+	  Adding OCSP::SingleResponse at the same time allows exposing
+	  OCSP_check_validity(). With this, the code above can be rewritten as:
 
-	* vm_core.h (EXEC_EVENT_HOOK_AND_POP_FRAME): add to use
-	  `rb_threadptr_exec_event_hooks_and_pop_frame()'.
+	    basic = res.basic
+	    single = basic.find_response(certid_target)
+	    result = single.check_validity
 
-	* vm.c (vm_exec): use EXEC_EVENT_HOOK_AND_POP_FRAME() while
-	  exception handling. While exception handling, if an exception
-	  is raised in hooks, need to pop current frame and raise this
-	  raised exception by hook.
+	* test/openssl/test_ocsp.rb: Test this.
 
-	* test/ruby/test_settracefunc.rb: add a test.

+	* ext/openssl/ossl_ocsp.c (ossl_ocspbres_add_status): Allow specifying
+	  the times (thisUpdate, nextUpdate and revocationTime) with Time
+	  objects. Currently they accepts only relative seconds from the current
+	  time. This is inconvenience, especially for revocationTime. When
+	  Integer is passed, they are still treated as relative times. Since the
+	  type check is currently done with rb_Integer(), this is a slightly
+	  incompatible change. Hope no one passes a relative time as String or
+	  Time object...
+	  Also, allow passing nil as nextUpdate. It is optional.

-	* vm.c: support variable VM/Machine stack sizes.
-	  Specified by the following environment variables:
-	    - RUBY_THREAD_VM_STACK_SIZE: vm stack size used at thread creation.
-	      default: 128KB (32bit CPU) or 256KB (64bit CPU).
-	    - RUBY_THREAD_MACHINE_STACK_SIZE: machine stack size used at thread
-	      creation. default: 512KB or 1024KB.
-	    - RUBY_FIBER_VM_STACK_SIZE: vm stack size used at fiber creation.
-	      default: 64KB or 128KB.
-	    - RUBY_FIBER_MACHINE_STACK_SIZE: machine stack size used at fiber
-	      creation. default: 256KB or 256KB.
-	  This values are specified at launched timing. You can not change
-	  these values at running time.
-	  Environ variables are only *hints* because:
-	    - They are aligned to 4KB.
-	    - They have minimum values (depend on OSs).
-	    - Machine stack settings are ignored by some OSs.
-	  Default values especially fiber stack sizes are increased.
-	  This change affect Fiber's behavior:
-	    (1) You can run more complex program on a Fiber.
-	    (2) You can not make many (thousands) Fibers because of
-	        lack of address space (on 32bit CPU).
-	  If (2) bothers you,
-	    (a) Use 64bit CPU with big memory, or
-	    (b) Specify RUBY_FIBER_(VM|MACHINE)_STACK_SIZE correctly.
-	  You need to choose correct stack size carefully. These values
-	  are completely rely on systems (OS/compiler and so on).

-
-	* method.h: remove `VM_METHOD_TYPE_CFUNC_FRAMELESS' method type.
-	  This method type is for optimized CFUNC such as Fixnum#+ and so on.
-	  This feature is half-baked and no way to use them.
-	  [Background]
-	  Now, VM has opt_plus instructions to optimize `+' methods for
-	  some Classes (such as Fixnum, Float (flonum)). We call this
-	  type of instructions as `specialized instructions'.
-	  This simple technique improve simple program dramatically.
-	  However, we can make specialized instructions for only several
-	  types (classes) and selectors (method names) because a large
-	  instruction will be slow. In other words, this technique has no
-	  extensibility.
-	  To overcome this problem, VM_METHOD_TYPE_CFUNC_FRAMELESS was
-	  introduced (r37198). This type is a variant of CFUNC, but called
-	  their functions directly without building a method frame.
-	  Any CFUNC method can be defined as frameless methods if a method
-	  is not needed to make method frame. Frameless methods are faster
-	  as specialized instructions (a bit slower, but no need to care).
-	  No problem described at
-	  http://charlie.bz/blog/why-do-singleton-methods-make-ruby-slow
-	  because this technique doesn't see class, but see method body
-	  itself. Alias is also no problem.
-	  [Problem]
-	  However, we can't set frameless method type for polymorphic methods
-	  such as Array#[]. Necessity for method frame depends on which
-	  parameter type. For example, Fixnum#+ needs method frame if
-	  coerce is needed. Current VM_METHOD_TYPE_CFUNC_FRAMELESS is not
-	  flexible and need more tuning to introduce it.
-	  Expected behavior of frameless method type may be:
-	    result = optimized_cfunc(params); /* call optimized cfunc */
-	    if (result == Qundef) { result = normal_cfunc(); }
-	  This is why I say this feature is half-baked.
-	  We need to learn primitive method in Smalltalk more.
-	  (I heard this name at RubyConf Taiwan this month. Thanks!)
-	  [Conclusion]
-	  I remove this feature and consider again.
-	  This feature goes to next minor (2.1?).
-	  Nobody may use this feature and there is no compatibility issue.
-
-	* proc.c (rb_method_entry_arity): ditto.
-
-	* vm_eval.c, vm_insnhelper.c, vm_method.c: ditto.

-Tue Dec 18 04:58:22 2012  Koichi Sasada  <ko1@atdot.net>
-
-	* vm_trace.c (fill_id_and_klass): TracePoint#defined_class returns
-	  singleton class. `set_trace_func' passed attached class (which is
-	  attached/modified by singleton class) by 6th block parameter if it
-	  is singleton class. Previous behavior follows this spec.
-	  However, this method named `defined_class' should return singleton
-	  class directly because singleton methods are defined in singleton
-	  class. There are no compatible issue because TracePoint is introduced
-	  after 2.0.
-	  But compatibility with `set_trace_func' is broken. This means that
-	  you can not replace all `set_trace_func' code with TracePoint
-	  without consideration of this behavior.
-	  [Bug #7554]
-
-	* test/ruby/test_settracefunc.rb: change a test to catch up

-	* signal.c (rb_f_kill): remove rb_thread_polling() because this

-	  enough time to wait. It depend on kernel behavior. And,
-	  rb_thread_polling() doesn't make sense anyway. When rb_thread_alone()
-	  is true, it doesn't wait at all and Process.kill() users don't
-	  expect threading changes Process.kill() behavior. [Bug #7560]

-
-	* fix the behavior when a module is included into a refinement.
-	  This change is a little tricky, so it might be better to prohibit
-	  module inclusion to refinements.
-
-	* include/ruby/ruby.h (RMODULE_INCLUDED_INTO_REFINEMENT): new flag
-	  to represent that a module (iclass) is included into a refinement.
-
-	* class.c (include_modules_at): set RMODULE_INCLUDED_INTO_REFINEMENT
-	  if klass is a refinement.
-
-	* eval.c (rb_mod_refine): set the superclass of a refinement to the
-	  refined class for super.
-
-	* eval.c (rb_using_refinement): skip the above superclass (the
-	  refined class) when creating iclasses for refinements.  Otherwise,
-	  `using Refinement1; using Refinement2' creates iclasses:
-	  <Refinement2> -> <RefinedClass> -> <Refinement1> -> RefinedClass,
-	  where <Module> is an iclass for Module, so RefinedClass is
-	  searched before Refinement1.  The correct iclasses should be
-	  <Refinement2> -> <Refinement1> -> RefinedClass.
-
-	* vm_insnhelper.c (vm_search_normal_superclass): if klass is an
-	  iclass for a refinement, use the refinement's superclass instead
-	  of the iclass's superclass.  Otherwise, multiple refinements are
-	  searched by super.  For example, if a refinement Refinement2
-	  includes a module M (i.e., Refinement2 -> <M> -> RefinedClass,
-	  and if refinements iclasses are <Refinement2> -> <M>' ->
-	  <Refinement1> -> RefinedClass, then super in <Refinement2> should
-	  use Refinement2's superclass <M> instead of <Refinement2>'s
-	  superclass <M>'.
-
-	* vm_insnhelper.c (vm_search_super_method): do not raise a
-	  NotImplementError if current_defined_class is a module included
-	  into a refinement.  Because of the change of
-	  vm_search_normal_superclass(), the receiver might not be an
-	  instance of the module('s iclass).

-
-Thu Dec  6 18:23:05 2012  Shugo Maeda  <shugo@ruby-lang.org>
-
-	* revised r37993 to avoid SEGV/ILL in tests.  In r37993, a method
-	  entry with VM_METHOD_TYPE_REFINED holds only the original method
-	  definition, so ci->me is set to a method entry allocated in the
-	  stack, and it causes SEGV/ILL.  In this commit, a method entry
-	  with VM_METHOD_TYPE_REFINED holds the whole original method entry.
-	  Furthermore, rb_thread_mark() is changed to mark cfp->klass to
-	  avoid GC for iclasses created by copy_refinement_iclass().
-
-	* vm_method.c (rb_method_entry_make): add a method entry with
-	  VM_METHOD_TYPE_REFINED to the class refined by the refinement if
-	  the target module is a refinement.  When a method entry with
-	  VM_METHOD_TYPE_UNDEF is invoked by vm_call_method(), a method with
-	  the same name is searched in refinements.  If such a method is
-	  found, the method is invoked.  Otherwise, the original method in
-	  the refined class (rb_method_definition_t::body.orig_me) is
-	  invoked.  This change is made to simplify the normal method lookup
-	  and to improve the performance of normal method calls.
-
-	* vm_method.c (EXPR1, search_method, rb_method_entry),
-	  vm_eval.c (rb_call0, rb_search_method_entry): do not use
-	  refinements for method lookup.
-
-	* vm_insnhelper.c (vm_call_method): search methods in refinements if
-	  ci->me is VM_METHOD_TYPE_REFINED.  If the method is called by
-	  super (i.e., ci->call == vm_call_super_method), skip the same
-	  method entry as the current method to avoid infinite call of the
-	  same method.
-
-	* class.c (include_modules_at): add a refined method entry for each
-	  method defined in a module included in a refinement.
-
-	* class.c (rb_prepend_module): set an empty table to
-	  RCLASS_M_TBL(klass) to add refined method entries, because
-	  refinements should have priority over prepended modules.
-
-	* proc.c (mnew): use rb_method_entry_with_refinements() to get
-	  a refined method.
-
-	* vm.c (rb_thread_mark): mark cfp->klass for iclasses created by
-	  copy_refinement_iclass().
-
-	* vm.c (Init_VM), cont.c (fiber_init): initialize th->cfp->klass.
-
-	* test/ruby/test_refinement.rb (test_inline_method_cache): do not skip
-	  the test because it should pass successfully.
-
-	* test/ruby/test_refinement.rb (test_redefine_refined_method): new
-	  test for the case a refined method is redefined.

-	* vm_method.c (rb_method_entry_make): add a method entry with
-	  VM_METHOD_TYPE_REFINED to the class refined by the refinement if
-	  the target module is a refinement.  When a method entry with
-	  VM_METHOD_TYPE_UNDEF is invoked by vm_call_method(), a method with
-	  the same name is searched in refinements.  If such a method is
-	  found, the method is invoked.  Otherwise, the original method in
-	  the refined class (rb_method_definition_t::body.orig_def) is
-	  invoked.  This change is made to simplify the normal method lookup
-	  and to improve the performance of normal method calls.
-

-	  vm_eval.c (rb_call0, rb_search_method_entry): do not use

-	  method entry as the current method to avoid infinite call of the
-	  same method.
-
-	* class.c (include_modules_at): add a refined method entry for each
-	  method defined in a module included in a refinement.
-
-	* class.c (rb_prepend_module): set an empty table to
-	  RCLASS_M_TBL(klass) to add refined method entries, because
-	  refinements should have priority over prepended modules.
-
-	* proc.c (mnew): use rb_method_entry_with_refinements() to get
-	  a refined method.
-
-	* test/ruby/test_refinement.rb (test_inline_method_cache): do not skip
-	  the test because it should pass successfully.

-Tue Oct 23 12:57:29 2012  Koichi Sasada  <ko1@atdot.net>
-
-	* vm_core.h, vm_insnhelper.c, vm_eval.c (OPT_CALL_CFUNC_WITHOUT_FRAME):
-	  add a new optimization and its macro `OPT_CALL_CFUNC_WITHOUT_FRAME'.
-	  This optimization makes all cfunc method calls `frameless', which
-	  is faster than ordinal cfunc method call.
-	  If `frame' is needed (for example, it calls another method with
-	  `rb_funcall()'), then build a frame. In other words, this
-	  optimization delays frame building.
-	  However, to delay the frame building, we need additional overheads:
-	    (1) Store the last call information.
-	    (2) Check the delayed frame building before the frame is needed.
-	    (3) Overhead to build a delayed frame.
-	  rb_thread_t::passed_ci is storage of delayed cfunc call information.
-	  (1) is lightweight because it is only 1 assignment to `passed_ci'.
-	  To achieve (2), we modify GET_THREAD() to check `passed_ci' every
-	  time. It causes 10% overhead on my environment.
-	  This optimization only works for cfunc methods which do not need
-	  their `frame'.
-	  After evaluation on my environment, this optimization does not
-	  effective every time. Because of this evaluation results, this
-	  optimization is disabled at default.
-
-	* vm_insnhelper.c, vm.c: add VM_PROFILE* macros to measure behaviour
-	  of VM internals. I will extend this feature.
-
-	* vm_method.c, method.h: change parameters of the `invoker' function.
-	  Receive `func' pointer as the first parameter.

-	  This method is similar to VM_METHOD_TYPE_CFUNC methods, but

+	* ext/openssl/lib/openssl/ssl.rb (SSLSocket): Move the implementation of

+	  Currently this is delayed until ossl_ssl_setup(), which is called from
+	  SSLSocket#accept or #connect. Say we call SSLSocket#hostname= with an

-	  These information are stored in rb_call_info_t at the compile
+	* ext/openssl/ossl_ssl.c (ossl_ssl_initialize): Added. Almost the same
+	  as the Ruby version but this instantiate the SSL object at the same
 	  time.
-	  This technique simplifies parameter passing at related
-	  function calls (~10% speedups for simple method invocation at
-	  my machine).
-	  `rb_call_info_t' also has new function pointer variable `call'.
-	  This `call' variable enables to customize method (block)
-	  invocation process for each place. However, it always call
-	  `vm_call_general()' at this changes.
-	  `rb_call_info_t' also has temporary variables for method
-	  (block) invocation.
-
-	* vm_core.h, compile.c, insns.def: introduce VM_CALL_ARGS_SKIP_SETUP

-	      If the last flag is true, then clean the hooks list.
-	      In other words, deleted hooks are contained by `hooks'.
-	      Cleanup process should run before traversing the list.
-	  (2) Change check mechanism

-	      Normal hooks are guarded from exception by rb_protect().
-	      However, this protection is overhead for too simple
-	      functions which never cause exceptions.  `raw' hooks

+	* numeric.c (rb_int_modulo): {Fixnum,Bignum}#modulo is unified into

-	* iseq.c, vm_eval.c: set th->base_block properly.
-	  th->base_block is information for (a) parsing, (b) compiling
-	  and (c) setting up the frame to execute the program passed by
-	  `eval' method.  For example, (1) parser need to know up-level
-	  variables to detect it is variable or method without paren.
-	  Befor (a), (b) and (c), VM set th->base_block by passed bindng
-	  (or previous frame information).  After execute (a), (b) and (c),
-	  VM should clear th->base_block.  However, if (a), (b) or (c)
-	  raises an exception, then th->base_block is not cleared.
-	  Problem is that the uncleared value th->balo_block is used for
-	  irrelevant iseq compilation.  It causes SEGV or critical error.
-	  I tried to solve this problem: to clear them before exception,
-	  but finally I found out that it is difficult to do it (Ruby
-	  program can be run in many places).
-	  Because of this background, I set th->base_block before
-	  compiling iseq and restore it after compiling.
-	  Basically, th->base_block is dirty hack (similar to global
-	  variable) and this patch is also dirty.

-
-	* vm_core.h: remove VM_FRAME_MAGIC_FINISH (finish frame type).
-	  Before this commit:
-	    `finish frame' was place holder which indicates that VM loop
-	    needs to return function.
-	    If a C method calls a Ruby methods (a method written by Ruby),
-	    then VM loop will be (re-)invoked.  When the Ruby method returns,
-	    then also VM loop should be escaped.  `finish frame' has only
-	    one instruction `finish', which returns VM loop function.
-	    VM loop function executes `finish' instruction, then VM loop
-	    function returns itself.
-	    With such mechanism, `leave' instruction (which returns one
-	    frame from current scope) doesn't need to check that this `leave'
-	    should also return from VM loop function.
-	    Strictly, one branch can be removed from `leave' instruction.
-	  Consideration:
-	    However, pushing the `finish frame' needs costs because
-	    it needs several memory accesses.  The number of pushing
-	    `finish frame' is greater than I had assumed.  Of course,
-	    pushing `finish frame' consumes additional control frame.
-	    Moreover, recent processors has good branch prediction,
-	    with which we can ignore such trivial checking.
-	  After this commit:
-	    Finally, I decide to remove `finish frame' and `finish'
-	    instruction.  Some parts of VM depend on `finish frame',
-	    so the new frame flag VM_FRAME_FLAG_FINISH is introduced.
-	    If this frame should escape from VM function loop, then
-	    the result of VM_FRAME_TYPE_FINISH_P(cfp) is true.
-	    `leave' instruction checks this flag every time.
-	    I measured performance on it.  However on my environments,
-	    it improves some benchmarks and slows some benchmarks down.
-	    Maybe it is because of C compiler optimization parameters.
-	    I'll re-visit here if this cause problems.
-
-	* insns.def (leave, finish): remove finish instruction.

-	* vm_core.h: remove lfp (local frame pointer) and rename
-	  dfp (dynamic frame pointer) to ep (environment pointer).
-	  This change make VM `normal' (similar to other interpreters).
-	  Before this commit:
-	    Each frame has two env pointers lfp and dfp.  lfp points
-	    local environment which is method/class/toplevel frame.
-	    lfp[0] is block pointer.
-	    dfp is block local frame. dfp[0] points previous (parent)
-	    environment pointer.
-	    lfp == dfp when frame is method/class/toplevel.
-	    You can get lfp from dfp by traversing previous environment
-	    pointers.
-	  After this commit:
-	    Each frame has only `ep' to point respective environment.
-	    If there is parent environment, then ep[0] points parent
-	    environment (as dfp).  If there are no more environment,
-	    then ep[0] points block pointer (as lfp).  We call such ep
-	    as `LEP' (local EP).  We add some macros to get LEP and to
-	    detect LEP or not.
-	    In short, we replace dfp and lfp with ep and LEP.
-	  rb_block_t and rb_binding_t member `lfp' and `dfp' are removed
-	  and member `ep' is added.
-	  rename rb_thread_t's member `local_lfp' and `local_svar' to
-	  `root_lep' and `root_svar'.
-	  (VM_EP_PREV_EP(ep)): get previous environment pointer.  This macro
-	    assume that ep is not LEP.
-	  (VM_EP_BLOCK_PTR(ep)): get block pointer.  This macro assume
-	    that ep is LEP.

+	* parse.y (yycompile0): use the default parameter.
 
-	* vm.c (RubyVM::FrameInfo): add a class to access each frame
-	  information.  You don't need to parse strings from caller().
-	  FrameInfo has the following methods:
-	    FrameInfo#name: method name, class name, etc with decorations.
-	    FrameInfo#basename: name without decorations.
-	    FrameInfo#line_no: line number.
-	    FrameInfo#filename: file name.
-	    FrameInfo#filepath: full filepath.
-	    FrameInfo#iseq: iseq if it is iseq frame (defined by ruby script)
-	    FrameInfo#to_s: return caller() method style string.
-	  RubyVM::FrameInfo.caller(n, lev) returns array of FrameInfo objects.
-	  The name "RubyVM::FrameInfo.caller" is long and ambiguous (it is
-	  confusing with Kernel::caller() method), we need to change the name
-	  before Ruby 2.0 release. Good names or comments are welcome.
+Wed Apr 20 10:25:53 2016  Nobuyoshi Nakada  <nobu@ruby-lang.org>

+	  creating a string buffer.
 
-	* benchmark/bm_vm3_backtrace.rb: added to check above improvement.
-	  FYI: measurement on my laptop, 1.9.3p229 needs 5.125 sec,

-	* ext/openssl/ossl_ssl.c: Allow disabling client-side renegotiation.
-	* test/openssl/test_ssl.rb: Simple tests for this.
+	* error.c (rb_report_bug_valist): take va_list instead of variadic
+	  arguments, and just report the bug but not abort.
 
-	  Client-side renegotiation is still considered problematic, even
-	  when used in the context of secure renegotiation (RI, RFC 5746).
-	  The changes allow users to either completely disable client
-	  renegotiation on the server, or to specify a maximum number of
-	  handshakes allowed in total. The number of total handshakes is
-	  counted in a callback set as SSL_set_info_callback. If the
-	  maximum number of handshakes is exceeded an error will be raised
-	  We do not support renegotiation in the OpenSSL extension, therefore
-	  this feature can only be tested externally.
-	  The feature is opt-in, the default setting will be to allow
-	  unlimited client renegotiation, as was the case before.

-	* test/openssl/test_ssl.rb: Clarify the intention of errors to be

-	* vm_eval.c (rb_f_caller): caller() method accepts second optional
-	  argument `n' which specify how many frames should return.
-	  For example, `caller(0, 1)' returns only one frame information
-	  which calls caller() method.  If there are less than n frame

-	* vm.c: add RubyVM::Backtrace object (btobj).
-	  Backtrace information contains an array consists of location
-	  information for each frames by string.
-	  RubyVM::Backtrace object is lightweight backtrace information,
-	  which contains complete information to generate traditional style
-	  backtrace (an array of strings) with faster generation.
-	  If someone accesses to backtrace information via
-	  Exception#backtrace, then convert a RubyVM::Backtrace object to
-	  traditional style backtrace.
-	  This change causes incompatibility on marshal dumped binary
-	  of Exception.  If you have any trouble on it, please tell us
-	  before Ruby 2.0 release.

-	* compile.c (compile_array, compile_array_):
-	  Divide big array (or hash) literals into several blocks and
-	  concatenate them.  There was a problem that a big array (hash)
-	  literal causes SystemStackError exception (stack overflow)
-	  because VM push all contents of the literal onto VM stack to
-	  make an array (or hash).  To solve this issue, we make several
-	  arrays (hashes) and concatenate them to make a big array (hash)
-	  object.  [ruby-dev:37701] [Bug #982]

-	* compile.c (iseq_compile_each, setup_args): use modified
-	  compile_array.

+	  Also heap_pages_max_slots is calculated at the begging of sweeping

+	  To simplify this logic, we introduced new global value

-	  In OpenSSL, OP_DONT_INSERT_EMPTY_FRAGMENTS is used to prevent
-	  TLS-CBC-IV vulnerability described at
-	  http://www.openssl.org/~bodo/tls-cbc.txt
-	  It's known issue of TLSv1/SSLv3 but it attracts lots of attention
-	  these days as BEAST attack. (CVE-2011-3389)
+	* enc/unicode/case-folding.rb, casefold.h: Tweaked handling of 6
+	  special cases in CaseUnfold_11_Table.
 
-	  Until now ossl sets OP_ALL at SSLContext allocation and call
-	  SSL_CTX_set_options at connection.  SSL_CTX_set_options updates the
-	  value by using |= so bits set by OP_ALL cannot be unset afterwards.
+	* enc/unicode.c: Adjustments for above.
 
-	  This commit changes to call SSL_CTX_set_options only 1 time for each
-	  SSLContext. It sets the specified value if SSLContext#options= are
-	  called and sets OP_ALL if not.
+	* test/ruby/enc/test_case_mapping.rb: Tests for the above: Some tests in
+	  test_titlecase activated; test_greek added. A test in test_cherokee fixed.
 
-	  To help users to unset bits in OP_ALL, this commit also adds several
-	  constant to SSL such as
-	  OpenSSL::SSL::OP_DONT_INSERT_EMPTY_FRAGMENTS.  These constants were

-Fri Aug 26 19:12:08 2011  Hiroshi Nakamura  <nahi@ruby-lang.org>
-
-	* variable.c: Make autoload thread-safe. See #921.
-
-	  What's the problem?
-	    autoload is thread unsafe. When we define a constant to be
-	    autoloaded, we expect the constant construction is invariant. But
-	    current autoload implementation allows other threads to access the
-	    constant while the first thread is loading a file.
-
-	  What's happening inside?
-	    The current implementation uses Qundef as a marker of autoload in
-	    Constant table. Once the first thread find Qundef as a value at
-	    constant lookup, it starts loading a defined feature. Generally a
-	    loaded file overrides the Qundef in Constant table by module/class
-	    declaration at very beginning lines of the file, so other threads
-	    can see the new Module/Class object before feature loading is
-	    finished. It breaks invariant construction.
-
-	  How to solve?
-	    To ensure invariant constant construction, we need to override
-	    Qundef with defined Object after the feature loading. For keeping
-	    Qundef in Constant table, I expanded autoload_data struct in
-	    Module to have a slot for keeping the defined object while feature
-	    loading. And changed Module's constant lookup/update logic a
-	    little so that the slot is only visible from the thread which
-	    invokes feature loading. (== the first thread which accessed the
-	    autoload constant)
-
-	  Evaluation?
-	    All test passes (bootstrap test, test-all and RubySpec) and added
-	    8 tests for threading behavior. Extra logics are executed only
-	    when Qundef is found, so no perf drop should happen except
-	    autoloading.

-	  This problem is caused by changing dfp (dynamic env pointer)
-	  from saved dfp.  Saved dfp is pointed env in VM stack.  However,
-	  the dfp can be moved because VM copies env from VM stack to
-	  the heap.  At this copying, dfp was also changed.  To solve this
-	  problem, I'll try to change throw mechanism (not save target dfp,
-	  but save target cfp).

+with all sufficient information, see the ChangeLog file or Redmine
+(e.g. <tt>https://bugs.ruby-lang.org/issues/$FEATURE_OR_BUG_NUMBER</tt>)
 
-== Changes since the 1.9.3 release
+== Changes since the 2.3.0 release
 
 === Language changes
 
-* Added keyword arguments.
+* Multiple assignment in conditional expression is now allowed.
+  [Feature #10617]
 
-* Added %i and %I for symbol list creation (similar to %w and %W).
+=== Core classes updates (outstanding ones only)
 
-* Default source encoding is changed to UTF-8. (was US-ASCII)
+* Array
 
-* No warning for unused variables starting with '_'
+  * Array#max and Array#min.  [Feature #12172]

-    from a method or a block.
-  * added RubyVM::InstructionSequence#path, #absolute_path, #label,
-    #base_label and #first_lineno to retrieve information from where
-    the instruction sequence was defined.
-  * added Environment variables to specify stack usage:

-    These variables are checked only at launched time.
-  * added constant DEFAULT_PARAMS to get above default parameters.
-
-* Signal
-  * added method:
-    * added Signal.signame which returns signal name
-
-  * incompatible changes:
-    * Signal.trap raises ArgumentError when :SEGV, :BUS, :ILL, :FPE, :VTALRM
-      are specified.
 
-* String
-  * added method:
-    * added String#b returning a copied string whose encoding is ASCII-8BIT.

-    Easy to use and efficient implementation.
-
-* toplevel
-  * added method:

-
-=== Core classes compatibility issues (excluding feature bug fixes)
-
-* Array#values_at
-
-  See above.
-
-* String#lines
-* String#chars
-* String#codepoints
-* String#bytes
-
-  These methods no longer return an Enumerator, although passing a
-  block is still supported for backwards compatibility.
-
-  Code like str.lines.with_index(1) { |line, lineno| ... } no longer
-  works because str.lines returns an array.  Replace lines with
-  each_line in such cases.
-
-* IO#lines
-* IO#chars
-* IO#codepoints
-* IO#bytes
-* ARGF#lines
-* ARGF#chars
-* ARGF#bytes
-* StringIO#lines

-
-  These methods are deprecated in favor of each_line, each_byte,
-  each_char and each_codepoint.
-
-* Proc#==
-* Proc#eql?
-
-  These methods were removed. Two procs are == only when they are
-  the same object.
-
-* Fixnum
-* Bignum
-* Float
+  * MatchData#named_captures [Feature #11999]
+  * MatchData#values_at supports named captures [Feature #9179]
 
-  Fixnums, Bignums and Floats are frozen.
+* Regexp
 
-* Signal.trap
+  * Regexp#match? [Feature #8110]
+    This returns bool and doesn't save backref.
 
-  See above.
+* Regexp/String: Updated Unicode version from 8.0.0 to 9.0.0 [Feature #12513]
 
-* Merge Onigmo.
-  https://github.com/k-takata/Onigmo
+* RubyVM::Env
 
-* The :close_others option is true by default for system() and exec().
-  Also, the close-on-exec flag is set by default for all new file descriptors.
-  This means file descriptors doesn't inherit to spawned process unless
-  explicitly requested such as system(..., fd=>fd).
+  * RubyVM::Env was removed.
 
-* Kernel#respond_to? against a protected method now returns false
-  unless the second argument is true.
+* String
 
-* Kernel#respond_to_missing?
-* Kernel#initialize_clone
-* Kernel#initialize_dup
+  * String#upcase, String#downcase, String#capitalize, String#swapcase and
+    their bang variants work for all of Unicode, and are no longer limited
+    to ASCII. Supported encodings are UTF-8, UTF-16BE/LE, UTF-32BE/LE, and
+    ISO-8859-1~16. Variations are available with options. See the documentation
+    of String#downcase for details. [Feature #10085]
 
-  These methods are now private.
+  * String.new(capacity: size) [Feature #12024]
 
-* Thread#join, Thread#value
+* Symbol
 
-  See above.

-* Mutex#lock, Mutex#unlock, Mutex#try_lock, Mutex#synchronize and Mutex#sleep
+  * Symbol#upcase, Symbol#downcase, Symbol#capitalize, and Symbol#swapcase now
+    work for all of Unicode. See the documentation of String#downcase
+    for details. [Feature #10085]
 
-  See above.
+* Thread
 
-=== Stdlib updates (outstanding ones only)
+  * Thread#report_on_exception and Thread.report_on_exception
+    [Feature #6647]
 
-* cgi
-  * Add HTML5 tag maker.
-  * CGI#header has been renamed to CGI#http_header and
-    aliased to CGI#header.
-  * When HTML5 tagmaker called, overwrite CGI#header,
-    CGI#header function is to create a <header> element.
+=== Stdlib updates (outstanding ones only)
 
 * CSV
-  * Removed CSV::dump and CSV::load to protect users from dangerous
-    serialization vulnerability
-
-* iconv
-  * Iconv has been removed. Use String#encode instead.
-
-* io/console
-  * new methods:
-    * added IO#cooked which sets the terminal to cooked mode within the given block.
-    * added IO#cooked! which sets the terminal to cooked.
-  * extended method:
-    * IO#raw, IO#raw!, and IO#getch accept keyword arguments, :min and :time.
-
-* io/wait
-  * new features:
-    * added IO#wait_writable method.
-    * added IO#wait_readable method as alias of IO#wait.
-
-* json
-  * updated to 1.7.7.
-
-* net/http
-  * new features:
-    * Proxies are now automatically detected from the http_proxy environment
-      variable.  See Net::HTTP::new for details.
-    * gzip and deflate compression are now requested for all requests by
-      default.  See Net::HTTP for details.
-    * SSL sessions are now reused across connections for a single instance.
-      This speeds up connection by using a previously negotiated session.
-    * Requests may be created from a URI which sets the request_uri and host
-      header of the request (but does not change the host connected to).
-    * Responses contain the URI requested which allows easier implementation of
-      redirect following.
-  * new methods:
-    * Net::HTTP#local_host
-    * Net::HTTP#local_host=
-    * Net::HTTP#local_port
-    * Net::HTTP#local_port=
-  * extended method:
-    * Net::HTTP#connect uses local_host and local_port if specified.
-
-* net/imap
-  * new methods:
-    * Net::IMAP.default_port
-    * Net::IMAP.default_imap_port
-    * Net::IMAP.default_tls_port
-    * Net::IMAP.default_ssl_port
-    * Net::IMAP.default_imaps_port
-
-* objspace
-  * new method:
-    * ObjectSpace.reachable_objects_from(obj)
-
-* openssl
-  * Consistently raise an error when trying to encode nil values. All instances
-    of OpenSSL::ASN1::Primitive now raise TypeError when calling to_der on an
-    instance whose value is nil. All instances of OpenSSL::ASN1::Constructive
-    raise NoMethodError in the same case. Constructing such values is still
-    permitted.
-  * TLS 1.1 & 1.2 support by setting OpenSSL::SSL::SSLContext#ssl_version to
-    :TLSv1_2, :TLSv1_2_server, :TLSv1_2_client or :TLSv1_1, :TLSv1_1_server
-    :TLSv1_1_client. The version being effectively used can be queried
-    with OpenSSL::SSL#ssl_version. Furthermore, it is also possible to
-    blacklist the new TLS versions with OpenSSL::SSL:OP_NO_TLSv1_1 and
-    OpenSSL::SSL::OP_NO_TLSv1_2.
-  * Added OpenSSL::SSL::SSLContext#renegotiation_cb. A user-defined callback
-    may be set which gets called whenever a new handshake is negotiated. This
-    also allows to programmatically decline (client) renegotiation attempts.
-  * Support for "0/n" splitting of records as BEAST mitigation via
-    OpenSSL::SSL::OP_DONT_INSERT_EMPTY_FRAGMENTS.
-  * The default options for OpenSSL::SSL::SSLContext have changed to
-    OpenSSL::SSL::OP_ALL & ~OpenSSL::SSL::OP_DONT_INSERT_EMPTY_FRAGMENTS
-    instead of OpenSSL::SSL::OP_ALL only. This enables the countermeasure for
-    the BEAST attack by default.
-  * OpenSSL requires passwords for decrypting PEM-encoded files to be at least
-    four characters long. This led to awkward situations where an export with
-    a password with fewer than four characters was possible, but accessing the
-    file afterwards failed. OpenSSL::PKey::RSA, OpenSSL::PKey::DSA and
-    OpenSSL::PKey::EC therefore now enforce the same check when exporting a
-    private key to PEM with a password - it has to be at least four characters
-    long.
-  * SSL/TLS support for the Next Protocol Negotiation extension. Supported
-    with OpenSSL 1.0.1 and higher.
-  * OpenSSL::OPENSSL_FIPS allows client applications to detect whether OpenSSL
-    is FIPS-enabled. OpenSSL.fips_mode= allows turning on and off FIPS mode
-    manually in order to adapt to situations where FIPS mode would be an
-    explicit requirement.
-  * Authenticated Encryption with Associated Data (AEAD) is supported via
-    Cipher#auth_data= and Cipher#auth_tag/Cipher#auth_tag=.
-    Currently (OpenSSL 1.0.1c), only GCM mode is supported.
-
-* ostruct
-  * new methods:
-    * OpenStruct#[], []=
-    * OpenStruct#each_pair
-    * OpenStruct#eql?
-    * OpenStruct#hash
-    * OpenStruct#to_h converts the struct to a hash.
-  * extended method:
-    * OpenStruct.new also accepts an OpenStruct / Struct.
-
-* pathname
-  * extended method:
-    * Pathname#find returns an enumerator if no block is given.
-
-* rake
-  * rake has been updated to version 0.9.5.
-
-    This version is backwards-compatible with previous rake versions and
-    contains many bug fixes.
-
-    See
-    http://rake.rubyforge.org/doc/release_notes/rake-0_9_5_rdoc.html for a list
-    of changes in rake 0.9.3, 0.9.4 and 0.9.5.
-
-* RDoc
-  * RDoc has been updated to version 4.0
-
-    This version is largely backwards-compatible with previous rdoc versions.
-    The most notable change is an update to the ri data format (ri data must
-    be regenerated for gems shared across rdoc versions).  Further API changes
-    are internal and won't affect most users.
-
-    Notable changes include:
-
-    * Page support for ri.  Try `ri ruby:` for a list of pages in ruby or
-      `ri ruby:syntax/literals` for the syntax documentation for literals.
-
-      This also works for gems such as `ri rspec:README` for the rspec gem's
-      README file.
-    * Markdown support.  See ri RDoc::Markdown for details.
-
-    See https://github.com/rdoc/rdoc/blob/master/History.rdoc for a full list
-    of changes in rdoc 4.0.
-
-* resolv
-  * new methods:
-    * Resolv::DNS#timeouts=
-    * Resolv::DNS::Config#timeouts=
-
-* rexml
-  * REXML::Document#write supports Hash arguments.
-  * REXML::Document#write supports new :encoding option. It changes
-    XML document encoding. Without :encoding option, encoding in
-    XML declaration is used for XML document encoding.
-
-* RubyGems
-  * Updated to 2.0.14.
-
-    See http://rubygems.rubyforge.org/rubygems-update/History_txt.html#label-2.0.14+%2F+2013-11-12
-    for release notes.
-
-  * Updated to 2.0.10.  This fixes CVE_2013-4363:
-
-    http://rubygems.rubyforge.org/rubygems-update/CVE-2013-4363_txt.html
-
-  * Updated to 2.0.8.  This fixes CVE-2013-4287:
-
-    http://rubygems.rubyforge.org/rubygems-update/CVE-2013-4287_txt.html
-
-  * Updated to 2.0.0
-
-    RubyGems 2.0.0 features the following improvements:
-
-    * Improved support for default gems shipping with ruby 2.0.0+
-    * A gem can have arbitrary metadata through Gem::Specification#metadata
-    * `gem search` now defaults to --remote and is anchored like gem list.
-    * Added --document to replace --rdoc and --ri.  Use --no-document to
-      disable documentation, --document=rdoc to only generate rdoc.
-    * Only ri-format documentation is generated by default.
-    * `gem server` uses RDoc::Servlet from RDoc 4.0 to generate HTML
-      documentation.
-
-    For an expanded list of updates and bug fixes see:
-    https://github.com/rubygems/rubygems/blob/master/History.txt
-
-* shellwords
-  * Shellwords#shellescape now stringifies the given object using to_s.
-  * Shellwords#shelljoin accepts non-string objects in the given
-    array, each of which is stringified using to_s.
-
-* stringio
-  * deprecated methods:
-    * StringIO#lines, #bytes, #chars and #codepoints are deprecated.
-
-* syslog
-  * Added Syslog::Logger which provides a Logger API atop Syslog.
-  * Syslog::Priority, Syslog::Level, Syslog::Option and Syslog::Macros
-    are introduced for easy detection of available constants on a
-    running system.
 
-* tmpdir
-  * incompatible changes:
-    * Dir.mktmpdir uses FileUtils.remove_entry instead of
-      FileUtils.remove_entry_secure.  This means that applications should not
-      change the permission of the created temporary directory to make
-      accessible from other users.
+  * Add a liberal_parsing option. [Feature #11839]
+
+* Logger
+
+	* Allow specifying logger parameters in constructor such
+	  as level, progname, datetime_format, formatter. [Feature #12224]
+	* Add shift_period_suffix option. [Feature #10772]
+
+* OpenSSL
+
+  * OpenSSL is extracted as a gem and the upstream has been migrated to
+    https://github.com/ruby/openssl. OpenSSL still remains as a default gem.
+    Refer to its History.md for the full release note. [Feature #9612]
+
+* optparse
+
+  * Add an into option. [Feature #11191]
+
+=== Compatibility issues (excluding feature bug fixes)
+
+* Array#sum and Enumerable#sum are implemented.  [Feature #12217]
+  Ruby itself has no compatibility problem because Ruby didn't have sum method
+  for arrays before Ruby 2.4.
+  However many third party gems, activesupport, facets, simple_stats, etc,
+  defines sum method.  These implementations are mostly compatible but
+  there are subtle differences.
+  Ruby's sum method should be mostly compatible but it is impossible to
+  be perfectly compatible with all of them.
+
+* Fixnum and Bignum are unified into Integer  [Feature #12005]
+  Fixnum class and Bignum class is removed.
+  Integer class is changed from abstract class to concrete class.
+  For example, 0 is an instance of Integer: 0.class returns Integer.
+  The constants Fixnum and Bignum is bound to Integer.
+  So obj.kind_of?(Fixnum) works as obj.kind_of?(Integer).
+  At C-level, Fixnum object and Bignum object should be distinguished by
+  FIXNUM_P(obj) and RB_TYPE_P(obj, T_BIGNUM).
+  RUBY_INTEGER_UNIFICATION can be used to detect this feature.
+  ruby-2.4.0-preview1 (temporally) removes rb_cFixnum and rb_cBignum
+  to check the effect of incompatibility.
+  (rb_cFixnum and rb_cBignum may be defined as rb_cInteger later if
+  compilation failure of extension library is too big problem.)
+
+* String/Symbol#upcase/downcase/swapcase/capitalize(!) now work for all of
+  Unicode, not only for ASCII. [Feature #10085]
+  No change is needed if the data is in ASCII anyway or if the limitation
+  to ASCII was only tolerated while waiting for a more extensive implementation.
+  A change (using the :ascii option) is needed in cases where Unicode data
+  is processed, but the operation has to be limited to ASCII only.
+  A good example of this are internationalized domain names.
+
+=== Stdlib compatibility issues (excluding feature bug fixes)
 
-* yaml
-  * Syck has been removed.  YAML now completely depends on libyaml being
-    installed.
-  * libyaml is now bundled with ruby, for cases where the library is not
-    installed locally.
+* DateTime
 
-* zlib
-  * Added streaming support for Zlib::Inflate and Zlib::Deflate.  This allows
-    processing of a stream without the use of large amounts of memory.
-  * Added support for the new deflate strategies Zlib::RLE and Zlib::FIXED.
-  * Zlib streams are now processed without the GVL.  This allows gzip, zlib and
-    deflate streams to be processed in parallel.
-  * deprecated methods:
-    * Zlib::GzipReader#lines and #bytes are deprecated.
+  * DateTime#to_time now preserves timezone.  [Bug #12189]
 
-=== Stdlib compatibility issues (excluding feature bug fixes)
+* Time
+
+  * Time#to_time now preserves timezone.  [Bug #12271]
 
-* OpenStruct new methods can conflict with custom attributes named
-  "each_pair", "eql?", "hash" or "to_h".
+* thread
 
-* Dir.mktmpdir in lib/tmpdir.rb
+  * the extension library is removed.  Till 2.0 it was a pure ruby script
+    "thread.rb", which has precedence over "thread.so", and has been provided
+    in $LOADED_FEATURES since 2.1.
 
-  See above.
+* Tk
+  * Tk is removed from stdlib.  [Feature #8539]
+    https://github.com/ruby/tk is the new upstream.
 
 === C API updates
 
-* NUM2SHORT() and NUM2USHORT() added. They are similar to NUM2INT, but short.
+* ruby_show_version() will no longer exits the process, if
+  RUBY_SHOW_COPYRIGHT_TO_DIE is set to 0.  This will be the default in
+  the future.
+
+=== Supported platform changes
+
+* FreeBSD < 4 is no longer supported
+
+=== Implementation improvements
 
-* rb_newobj_of() and NEWOBJ_OF() added. They create a new object of a given class.
+* In some condition, `[x, y].max` and `[x, y].min` are optimized
+  so that a temporal array is not created.  The concrete condition is
+  an implementation detail: currently, the array literal must have no
+  splat, must have at least one expression but literal, the length must
+  be <= 0x100, and Array#max and min must not be redefined.  It will work
+  in most casual and real-life use case where it is written with intent
+  to `Math.max(x, y)`.
 
+* Thread deadlock detection now shows their backtrace and dependency. [Feature #8214]

-Perl).  It is simple, straight-forward, and extensible.
-
-
-== Features of Ruby
-
-*   Simple Syntax
-*   *Normal* Object-Oriented features(ex. class, method calls)
-*   *Advanced* Object-Oriented features(ex. Mix-in, Singleton-method)
-*   Operator Overloading
-*   Exception Handling
-*   Iterators and Closures
-*   Garbage Collection
-*   Dynamic Loading of Object files(on some architecture)
-*   Highly Portable (works on many Unix-like/POSIX compatible platforms
-    as well as Windows, Mac OS X, BeOS etc.)
-    cf. http://bugs.ruby-lang.org/projects/ruby-trunk/wiki/SupportedPlatforms

-
-== Ruby home-page
-
-The URL of the Ruby home-page is:
-
-http://www.ruby-lang.org/
-
-
-== Mailing list
-
-There is a mailing list to talk about Ruby.
-To subscribe this list, please send the following phrase
-
-        subscribe YourFirstName YourFamilyName
-e.g.
-        subscribe Joseph Smith
-
-in the mail body (not subject) to the address <mailto:ruby-talk-ctl@ruby-lang.org>.
-
-
-== How to compile and install
-
-This is what you need to do to compile and install Ruby:
-
-0.   If you want to use Microsoft Visual C++ to compile ruby,
-     read win32/README.win32 instead of this document.
-
-1.   If +./configure+ does not exist or is older than configure.in,
-     run autoconf to (re)generate configure.
-
-2.   Run +./configure+, which will generate config.h and Makefile.
-
-     Some C compiler flags may be added by default depending on your
-     environment.  Specify <tt>optflags=..</tt> and <tt>warnflags=..</tt> as
-     necessary to override them.
-
-3.   Edit +defines.h+ if you need. Usually this step will not be needed.
-
-4.   Remove comment mark(<tt>#</tt>) before the module names from +ext/Setup+
-     (or add module names if not present), if you want to link modules
-     statically.
-
-     If you don't want to compile non static extension modules
-     (probably on architectures which does not allow dynamic loading),
-     remove comment mark from the line "<tt>#option nodynamic</tt>" in
-     +ext/Setup+.
-
-     Usually this step will not be needed.
-
-5.   Run +make+.
-
-6.   Optionally, run '<tt>make check</tt>' to check whether the compiled Ruby
-     interpreter works well. If you see the message "<tt>check succeeded</tt>",
-     your ruby works as it should (hopefully).
-
-7.   Run '<tt>make install</tt>'
-
-     This command will create following directories and install files
-     onto them.
-
-     * <tt>${DESTDIR}${prefix}/bin</tt>
-     * <tt>${DESTDIR}${prefix}/include/ruby-${MAJOR}.${MINOR}.${TEENY}</tt>
-     * <tt>${DESTDIR}${prefix}/include/ruby-${MAJOR}.${MINOR}.${TEENY}/${PLATFORM}</tt>
-     * <tt>${DESTDIR}${prefix}/lib</tt>
-     * <tt>${DESTDIR}${prefix}/lib/ruby</tt>
-     * <tt>${DESTDIR}${prefix}/lib/ruby/${MAJOR}.${MINOR}.${TEENY}</tt>
-     * <tt>${DESTDIR}${prefix}/lib/ruby/${MAJOR}.${MINOR}.${TEENY}/${PLATFORM}</tt>
-     * <tt>${DESTDIR}${prefix}/lib/ruby/site_ruby</tt>
-     * <tt>${DESTDIR}${prefix}/lib/ruby/site_ruby/${MAJOR}.${MINOR}.${TEENY}</tt>
-     * <tt>${DESTDIR}${prefix}/lib/ruby/site_ruby/${MAJOR}.${MINOR}.${TEENY}/${PLATFORM}</tt>
-     * <tt>${DESTDIR}${prefix}/lib/ruby/vendor_ruby</tt>
-     * <tt>${DESTDIR}${prefix}/lib/ruby/vendor_ruby/${MAJOR}.${MINOR}.${TEENY}</tt>
-     * <tt>${DESTDIR}${prefix}/lib/ruby/vendor_ruby/${MAJOR}.${MINOR}.${TEENY}/${PLATFORM}</tt>
-     * <tt>${DESTDIR}${prefix}/lib/ruby/gems/${MAJOR}.${MINOR}.${TEENY}</tt>
-     * <tt>${DESTDIR}${prefix}/share/man/man1</tt>
-     * <tt>${DESTDIR}${prefix}/share/ri/${MAJOR}.${MINOR}.${TEENY}/system</tt>
-
-     If Ruby's API version is '_x.y.z_', the <tt>${MAJOR}</tt> is '_x_', the
-     <tt>${MINOR}</tt> is '_y_', and the <tt>${TEENY}</tt> is '_z_'.
-
-     *NOTE*: teeny of the API version may be different from one of
-     Ruby's program version
-
-     You may have to be a super user to install ruby.
-
-If you fail to compile ruby, please send the detailed error report with
-the error log and machine/OS type, to help others.
-
-Some extension libraries may not get compiled because of lack of
-necessary external libraries and/or headers, then you will need to run
-'<tt>make distclean-ext</tt>' to remove old configuration after
-installing them in such case.
-
-== Copying
-
-See the file +COPYING+.

-# README.EXT -  -*- RDoc -*- created at: Mon Aug  7 16:45:54 JST 1995
-
-This document explains how to make extension libraries for Ruby.
-
-= Basic Knowledge
-
-In C, variables have types and data do not have types.  In contrast,
-Ruby variables do not have a static type, and data themselves have
-types, so data will need to be converted between the languages.
-
-Data in Ruby are represented by the C type `VALUE'.  Each VALUE data
-has its data-type.
-
-To retrieve C data from a VALUE, you need to:
-
-1. Identify the VALUE's data type
-2. Convert the VALUE into C data
-
-Converting to the wrong data type may cause serious problems.
-
-== Data-Types
-
-The Ruby interpreter has the following data types:
-
-T_NIL       :: nil
-T_OBJECT    :: ordinary object
-T_CLASS     :: class
-T_MODULE    :: module
-T_FLOAT     :: floating point number
-T_STRING    :: string
-T_REGEXP    :: regular expression
-T_ARRAY     :: array
-T_HASH      :: associative array
-T_STRUCT    :: (Ruby) structure
-T_BIGNUM    :: multi precision integer
-T_FIXNUM    :: Fixnum(31bit or 63bit integer)
-T_COMPLEX   :: complex number
-T_RATIONAL  :: rational number
-T_FILE      :: IO
-T_TRUE      :: true
-T_FALSE     :: false
-T_DATA      :: data
-T_SYMBOL    :: symbol
-
-In addition, there are several other types used internally:
-
-T_ICLASS    :: included module
-T_MATCH     :: MatchData object
-T_UNDEF     :: undefined
-T_NODE      :: syntax tree node
-T_ZOMBIE    :: object awaiting finalization
-
-Most of the types are represented by C structures.
-
-== Check Data Type of the VALUE
-
-The macro TYPE() defined in ruby.h shows the data type of the VALUE.
-TYPE() returns the constant number T_XXXX described above.  To handle
-data types, your code will look something like this:
-
-  switch (TYPE(obj)) {
-    case T_FIXNUM:
-      /* process Fixnum */
-      break;
-    case T_STRING:
-      /* process String */
-      break;
-    case T_ARRAY:
-      /* process Array */
-      break;
-    default:
-      /* raise exception */
-      rb_raise(rb_eTypeError, "not valid value");
-      break;
-  }
-
-There is the data-type check function
-
-  void Check_Type(VALUE value, int type)
-
-which raises an exception if the VALUE does not have the type
-specified.
-
-There are also faster check macros for fixnums and nil.
-
-  FIXNUM_P(obj)
-  NIL_P(obj)
-
-== Convert VALUE into C Data
-
-The data for type T_NIL, T_FALSE, T_TRUE are nil, false, true
-respectively.  They are singletons for the data type.
-The equivalent C constants are: Qnil, Qfalse, Qtrue.
-Note that Qfalse is false in C also (i.e. 0), but not Qnil.
-
-The T_FIXNUM data is a 31bit or 63bit length fixed integer.
-This size is depend on the size of long: if long is 32bit then
-T_FIXNUM is 31bit, if long is 64bit then T_FIXNUM is 63bit.
-T_FIXNUM can be converted to a C integer by using the
-FIX2INT() macro or FIX2LONG().  Though you have to check that the
-data is really FIXNUM before using them, they are faster.  FIX2LONG()
-never raises exceptions, but FIX2INT() raises RangeError if the
-result is bigger or smaller than the size of int.
-There are also NUM2INT() and NUM2LONG() which converts any Ruby
-numbers into C integers.  These macros includes a type check,
-so an exception will be raised if the conversion failed.  NUM2DBL()
-can be used to retrieve the double float value in the same way.
-
-You can use the macros
-StringValue() and StringValuePtr() to get a char* from a VALUE.
-StringValue(var) replaces var's value with the result of "var.to_str()".
-StringValuePtr(var) does same replacement and returns char*
-representation of var.  These macros will skip the replacement if var
-is a String.  Notice that the macros take only the lvalue as their
-argument, to change the value of var in place.
-
-You can also use the macro named StringValueCStr(). This is just
-like StringValuePtr(), but always add nul character at the end of
-the result. If the result contains nul character, this macro causes
-the ArgumentError exception.
-StringValuePtr() doesn't guarantee the existence of a nul at the end
-of the result, and the result may contain nul.
-
-Other data types have corresponding C structures, e.g. struct RArray
-for T_ARRAY etc. The VALUE of the type which has the corresponding
-structure can be cast to retrieve the pointer to the struct.  The
-casting macro will be of the form RXXXX for each data type; for
-instance, RARRAY(obj).  See "ruby.h".
-
-There are some accessing macros for structure members, for example
-`RSTRING_LEN(str)' to get the size of the Ruby String object.  The
-allocated region can be accessed by `RSTRING_PTR(str)'.  For arrays,
-use `RARRAY_LEN(ary)' and `RARRAY_PTR(ary)' respectively.
-
-Notice: Do not change the value of the structure directly, unless you
-are responsible for the result.  This ends up being the cause of
-interesting bugs.
-
-== Convert C Data into VALUE
-
-To convert C data to Ruby values:
-
-FIXNUM ::
-
-  left shift 1 bit, and turn on LSB.
-
-Other pointer values::
-
-  cast to VALUE.
-
-You can determine whether a VALUE is pointer or not by checking its LSB.
-
-Notice Ruby does not allow arbitrary pointer values to be a VALUE.  They
-should be pointers to the structures which Ruby knows about.  The known
-structures are defined in <ruby.h>.
-
-To convert C numbers to Ruby values, use these macros.
-
-INT2FIX() :: for integers within 31bits.
-INT2NUM() :: for arbitrary sized integer.
-
-INT2NUM() converts an integer into a Bignum if it is out of the FIXNUM
-range, but is a bit slower.
-
-== Manipulating Ruby Data
-
-As I already mentioned, it is not recommended to modify an object's
-internal structure.  To manipulate objects, use the functions supplied
-by the Ruby interpreter. Some (not all) of the useful functions are
-listed below:
-
-=== String Functions
-
-rb_str_new(const char *ptr, long len) ::
-
-  Creates a new Ruby string.
-
-rb_str_new2(const char *ptr) ::
-rb_str_new_cstr(const char *ptr) ::
-
-  Creates a new Ruby string from a C string.  This is equivalent to
-  rb_str_new(ptr, strlen(ptr)).
-
-rb_tainted_str_new(const char *ptr, long len) ::
-
-  Creates a new tainted Ruby string.  Strings from external data
-  sources should be tainted.
-
-rb_tainted_str_new2(const char *ptr) ::
-rb_tainted_str_new_cstr(const char *ptr) ::
-
-  Creates a new tainted Ruby string from a C string.
-
-rb_sprintf(const char *format, ...) ::
-rb_vsprintf(const char *format, va_list ap) ::
-
-  Creates a new Ruby string with printf(3) format.
-
-  Note: In the format string, %i is used for Object#to_s (or Object#inspect if
-  '+' flag is set) output (and related argument must be a VALUE).  For integers
-  in format strings, use %d.
-
-rb_str_cat(VALUE str, const char *ptr, long len) ::
-
-  Appends len bytes of data from ptr to the Ruby string.
-
-rb_str_cat2(VALUE str, const char* ptr) ::
-
-  Appends C string ptr to Ruby string str.  This function is
-  equivalent to rb_str_cat(str, ptr, strlen(ptr)).
-
-rb_str_catf(VALUE str, const char* format, ...) ::
-rb_str_vcatf(VALUE str, const char* format, va_list ap) ::
-
-  Appends C string format and successive arguments to Ruby string
-  str according to a printf-like format.  These functions are
-  equivalent to rb_str_cat2(str, rb_sprintf(format, ...)) and
-  rb_str_cat2(str, rb_vsprintf(format, ap)), respectively.
-
-rb_enc_str_new(const char *ptr, long len, rb_encoding *enc) ::
-
-  Creates a new Ruby string with the specified encoding.
-
-rb_usascii_str_new(const char *ptr, long len) ::
-rb_usascii_str_new_cstr(const char *ptr) ::
-
-  Creates a new Ruby string with encoding US-ASCII.
-
-rb_str_resize(VALUE str, long len) ::
-
-  Resizes Ruby string to len bytes.  If str is not modifiable, this
-  function raises an exception.  The length of str must be set in
-  advance.  If len is less than the old length the content beyond
-  len bytes is discarded, else if len is greater than the old length
-  the content beyond the old length bytes will not be preserved but
-  will be garbage.  Note that RSTRING_PTR(str) may change by calling
-  this function.
-
-rb_str_set_len(VALUE str, long len) ::
-
-  Sets the length of Ruby string.  If str is not modifiable, this
-  function raises an exception.  This function preserves the content
-  upto len bytes, regardless RSTRING_LEN(str).  len must not exceed
-  the capacity of str.
-
-=== Array Functions
-
-rb_ary_new() ::
-
-  Creates an array with no elements.
-
-rb_ary_new2(long len) ::
-
-  Creates an array with no elements, allocating internal buffer
-  for len elements.
-
-rb_ary_new3(long n, ...) ::
-
-  Creates an n-element array from the arguments.
-
-rb_ary_new4(long n, VALUE *elts) ::
-
-  Creates an n-element array from a C array.
-
-rb_ary_to_ary(VALUE obj) ::
-
-  Converts the object into an array.
-  Equivalent to Object#to_ary.
-
-There are many functions to operate an array.  They may dump core if other
-types are given.
-
-rb_ary_aref(argc, VALUE *argv, VALUE ary) ::
-
-  Equivaelent to Array#[].
-
-rb_ary_entry(VALUE ary, long offset) ::
-
-  ary[offset]
-
-rb_ary_subseq(VALUE ary, long beg, long len) ::
-
-  ary[beg, len]
-
-rb_ary_push(VALUE ary, VALUE val) ::
-rb_ary_pop(VALUE ary) ::
-rb_ary_shift(VALUE ary) ::
-rb_ary_unshift(VALUE ary, VALUE val) ::
-
-rb_ary_cat(VALUE ary, const VALUE *ptr, long len) ::
-
-  Appends len elements of objects from ptr to the array.
-
-= Extending Ruby with C
-
-== Adding New Features to Ruby
-
-You can add new features (classes, methods, etc.) to the Ruby
-interpreter.  Ruby provides APIs for defining the following things:
-
-* Classes, Modules
-* Methods, Singleton Methods
-* Constants
-
-=== Class and Module Definition
-
-To define a class or module, use the functions below:
-
-  VALUE rb_define_class(const char *name, VALUE super)
-  VALUE rb_define_module(const char *name)
-
-These functions return the newly created class or module.  You may
-want to save this reference into a variable to use later.
-
-To define nested classes or modules, use the functions below:
-
-  VALUE rb_define_class_under(VALUE outer, const char *name, VALUE super)
-  VALUE rb_define_module_under(VALUE outer, const char *name)
-
-=== Method and Singleton Method Definition
-
-To define methods or singleton methods, use these functions:
-
-  void rb_define_method(VALUE klass, const char *name,
-		        VALUE (*func)(), int argc)
-
-  void rb_define_singleton_method(VALUE object, const char *name,
-			          VALUE (*func)(), int argc)
-
-The `argc' represents the number of the arguments to the C function,
-which must be less than 17.  But I doubt you'll need that many.
-
-If `argc' is negative, it specifies the calling sequence, not number of
-the arguments.
-
-If argc is -1, the function will be called as:
-
-  VALUE func(int argc, VALUE *argv, VALUE obj)
-
-where argc is the actual number of arguments, argv is the C array of
-the arguments, and obj is the receiver.
-
-If argc is -2, the arguments are passed in a Ruby array. The function
-will be called like:
-
-  VALUE func(VALUE obj, VALUE args)
-
-where obj is the receiver, and args is the Ruby array containing
-actual arguments.
-
-There are some more functions to define methods. One takes an ID
-as the name of method to be defined. See also ID or Symbol below.
-
-  void rb_define_method_id(VALUE klass, ID name,
-                           VALUE (*func)(ANYARGS), int argc)
-
-There are two functions to define private/protected methods:
-
-  void rb_define_private_method(VALUE klass, const char *name,
-			        VALUE (*func)(), int argc)
-  void rb_define_protected_method(VALUE klass, const char *name,
-			          VALUE (*func)(), int argc)
-
-At last, rb_define_module_function defines a module functions,
-which are private AND singleton methods of the module.
-For example, sqrt is the module function defined in Math module.
-It can be called in the following way:
-
-  Math.sqrt(4)
-
-or
-
-  include Math
-  sqrt(4)
-
-To define module functions, use:
-
-  void rb_define_module_function(VALUE module, const char *name,
-				 VALUE (*func)(), int argc)
-
-In addition, function-like methods, which are private methods defined
-in the Kernel module, can be defined using:
-
-  void rb_define_global_function(const char *name, VALUE (*func)(), int argc)
-
-To define an alias for the method,
-
-  void rb_define_alias(VALUE module, const char* new, const char* old);
-
-To define a reader/writer for an attribute,
-
-  void rb_define_attr(VALUE klass, const char *name, int read, int write)
-
-To define and undefine the `allocate' class method,
-
-  void rb_define_alloc_func(VALUE klass, VALUE (*func)(VALUE klass));
-  void rb_undef_alloc_func(VALUE klass);
-
-func has to take the klass as the argument and return a newly
-allocated instance.  This instance should be as empty as possible,
-without any expensive (including external) resources.
-
-=== Constant Definition
-
-We have 2 functions to define constants:
-
-  void rb_define_const(VALUE klass, const char *name, VALUE val)
-  void rb_define_global_const(const char *name, VALUE val)
-
-The former is to define a constant under specified class/module.  The
-latter is to define a global constant.
-
-== Use Ruby Features from C
-
-There are several ways to invoke Ruby's features from C code.
-
-=== Evaluate Ruby Programs in a String
-
-The easiest way to use Ruby's functionality from a C program is to
-evaluate the string as Ruby program.  This function will do the job:
-
-  VALUE rb_eval_string(const char *str)
-
-Evaluation is done under the current context, thus current local variables
-of the innermost method (which is defined by Ruby) can be accessed.
-
-Note that the evaluation can raise an exception. There is a safer
-function:
-
-  VALUE rb_eval_string_protect(const char *str, int *state)
-
-It returns nil when an error occur. Moreover, *state is zero if str was
-successfully evaluated, or nonzero otherwise.
-
-=== ID or Symbol
-
-You can invoke methods directly, without parsing the string.  First I
-need to explain about ID.  ID is the integer number to represent
-Ruby's identifiers such as variable names.  The Ruby data type
-corresponding to ID is Symbol.  It can be accessed from Ruby in the
-form:
-
-  :Identifier
-
-or
-
-  :"any kind of string"
-
-You can get the ID value from a string within C code by using
-
-  rb_intern(const char *name)
-  rb_intern_str(VALUE name)
-
-You can retrieve ID from Ruby object (Symbol or String) given as an
-argument by using
-
-  rb_to_id(VALUE symbol)
-  rb_check_id(volatile VALUE *name)
-  rb_check_id_cstr(const char *name, long len, rb_encoding *enc)
-
-These functions try to convert the argument to a String if it was not
-a Symbol nor a String.  The second function stores the converted
-result into *name, and returns 0 if the string is not a known symbol.
-After this function returned a non-zero value, *name is always a
-Symbol or a String, otherwise it is a String if the result is 0.
-The third function takes NUL-terminated C string, not Ruby VALUE.
-
-You can convert C ID to Ruby Symbol by using
-
-  VALUE ID2SYM(ID id)
-
-and to convert Ruby Symbol object to ID, use
-
-  ID SYM2ID(VALUE symbol)
-
-=== Invoke Ruby Method from C
-
-To invoke methods directly, you can use the function below
-
-  VALUE rb_funcall(VALUE recv, ID mid, int argc, ...)
-
-This function invokes a method on the recv, with the method name
-specified by the symbol mid.
-
-=== Accessing the Variables and Constants
-
-You can access class variables and instance variables using access
-functions.  Also, global variables can be shared between both
-environments.  There's no way to access Ruby's local variables.
-
-The functions to access/modify instance variables are below:
-
-  VALUE rb_ivar_get(VALUE obj, ID id)
-  VALUE rb_ivar_set(VALUE obj, ID id, VALUE val)
-
-id must be the symbol, which can be retrieved by rb_intern().
-
-To access the constants of the class/module:
-
-  VALUE rb_const_get(VALUE obj, ID id)
-
-See also Constant Definition above.
-
-= Information Sharing Between Ruby and C
-
-=== Ruby Constants That C Can Be Accessed From C
-
-As stated in section 1.3,
-the following Ruby constants can be referred from C.
-
-  Qtrue
-  Qfalse
-
-Boolean values.  Qfalse is false in C also (i.e. 0).
-
-  Qnil
-
-Ruby nil in C scope.
-
-== Global Variables Shared Between C and Ruby
-
-Information can be shared between the two environments using shared global
-variables.  To define them, you can use functions listed below:
-
-  void rb_define_variable(const char *name, VALUE *var)
-
-This function defines the variable which is shared by both environments.
-The value of the global variable pointed to by `var' can be accessed
-through Ruby's global variable named `name'.
-
-You can define read-only (from Ruby, of course) variables using the
-function below.
-
-  void rb_define_readonly_variable(const char *name, VALUE *var)
-
-You can defined hooked variables.  The accessor functions (getter and
-setter) are called on access to the hooked variables.
-
-  void rb_define_hooked_variable(const char *name, VALUE *var,
-				 VALUE (*getter)(), void (*setter)())
-
-If you need to supply either setter or getter, just supply 0 for the
-hook you don't need.  If both hooks are 0, rb_define_hooked_variable()
-works just like rb_define_variable().
-
-The prototypes of the getter and setter functions are as follows:
-
-  VALUE (*getter)(ID id, VALUE *var);
-  void (*setter)(VALUE val, ID id, VALUE *var);
-
-
-Also you can define a Ruby global variable without a corresponding C
-variable.  The value of the variable will be set/get only by hooks.
-
-  void rb_define_virtual_variable(const char *name,
-				  VALUE (*getter)(), void (*setter)())
-
-The prototypes of the getter and setter functions are as follows:
-
-  VALUE (*getter)(ID id);
-  void (*setter)(VALUE val, ID id);
-
-
-== Encapsulate C Data into a Ruby Object
-
-To wrap and objectify a C pointer as a Ruby object (so called
-DATA), use Data_Wrap_Struct().
-
-  Data_Wrap_Struct(klass, mark, free, sval)
-
-Data_Wrap_Struct() returns a created DATA object.  The klass argument
-is the class for the DATA object.  The mark argument is the function
-to mark Ruby objects pointed by this data.  The free argument is the
-function to free the pointer allocation.  If this is -1, the pointer
-will be just freed.  The functions mark and free will be called from
-garbage collector.
-
-These mark / free functions are invoked during GC execution.  No
-object allocations are allowed during it, so do not allocate ruby
-objects inside them.
-
-You can allocate and wrap the structure in one step.
-
-  Data_Make_Struct(klass, type, mark, free, sval)
-
-This macro returns an allocated Data object, wrapping the pointer to
-the structure, which is also allocated.  This macro works like:
-
-  (sval = ALLOC(type), Data_Wrap_Struct(klass, mark, free, sval))
-
-Arguments klass, mark, and free work like their counterparts in
-Data_Wrap_Struct().  A pointer to the allocated structure will be
-assigned to sval, which should be a pointer of the type specified.
-
-To retrieve the C pointer from the Data object, use the macro
-Data_Get_Struct().
-
-  Data_Get_Struct(obj, type, sval)
-
-A pointer to the structure will be assigned to the variable sval.
-
-See the example below for details.
-
-= Example - Creating dbm Extension
-
-OK, here's the example of making an extension library.  This is the
-extension to access DBMs.  The full source is included in the ext/
-directory in the Ruby's source tree.
-
-== Make the Directory
-
-  % mkdir ext/dbm
-
-Make a directory for the extension library under ext directory.
-
-== Design the Library
-
-You need to design the library features, before making it.
-
-== Write the C Code
-
-You need to write C code for your extension library.  If your library
-has only one source file, choosing ``LIBRARY.c'' as a file name is
-preferred.  On the other hand, in case your library has multiple source
-files, avoid choosing ``LIBRARY.c'' for a file name.  It may conflict
-with an intermediate file ``LIBRARY.o'' on some platforms.
-Note that some functions in mkmf library described below generate
-a file ``conftest.c'' for checking with compilation.  You shouldn't
-choose ``conftest.c'' as a name of a source file.
-
-Ruby will execute the initializing function named ``Init_LIBRARY'' in
-the library.  For example, ``Init_dbm()'' will be executed when loading
-the library.
-
-Here's the example of an initializing function.
-
-  void
-  Init_dbm(void)
-  {
-      /* define DBM class */
-      cDBM = rb_define_class("DBM", rb_cObject);
-      /* DBM includes Enumerate module */
-      rb_include_module(cDBM, rb_mEnumerable);
-
-      /* DBM has class method open(): arguments are received as C array */
-      rb_define_singleton_method(cDBM, "open", fdbm_s_open, -1);
-
-      /* DBM instance method close(): no args */
-      rb_define_method(cDBM, "close", fdbm_close, 0);
-      /* DBM instance method []: 1 argument */
-      rb_define_method(cDBM, "[]", fdbm_fetch, 1);
-
-      /* ... */
-
-      /* ID for a instance variable to store DBM data */
-      id_dbm = rb_intern("dbm");
-  }
-
-The dbm extension wraps the dbm struct in the C environment using
-Data_Make_Struct.
-
-  struct dbmdata {
-      int  di_size;
-      DBM *di_dbm;
-  };
-
-  obj = Data_Make_Struct(klass, struct dbmdata, 0, free_dbm, dbmp);
-
-This code wraps the dbmdata structure into a Ruby object.  We avoid
-wrapping DBM* directly, because we want to cache size information.
-
-To retrieve the dbmdata structure from a Ruby object, we define the
-following macro:
-
-  #define GetDBM(obj, dbmp) {\
-      Data_Get_Struct(obj, struct dbmdata, dbmp);\
-      if (dbmp->di_dbm == 0) closed_dbm();\
-  }
-
-This sort of complicated macro does the retrieving and close checking for
-the DBM.
-
-There are three kinds of way to receive method arguments.  First,
-methods with a fixed number of arguments receive arguments like this:
-
-  static VALUE
-  fdbm_delete(VALUE obj, VALUE keystr)
-  {
-        /* ... */
-  }
-
-The first argument of the C function is the self, the rest are the
-arguments to the method.
-
-Second, methods with an arbitrary number of arguments receive
-arguments like this:
-
-  static VALUE
-  fdbm_s_open(int argc, VALUE *argv, VALUE klass)
-  {
-      /* ... */
-      if (rb_scan_args(argc, argv, "11", &file, &vmode) == 1) {
-          mode = 0666;		/* default value */
-      }
-      /* ... */
-  }
-
-The first argument is the number of method arguments, the second
-argument is the C array of the method arguments, and the third
-argument is the receiver of the method.
-
-You can use the function rb_scan_args() to check and retrieve the
-arguments.  The third argument is a string that specifies how to
-capture method arguments and assign them to the following VALUE
-references.
-
-
-The following is an example of a method that takes arguments by Ruby's
-array:
-
-  static VALUE
-  thread_initialize(VALUE thread, VALUE args)
-  {
-      /* ... */
-  }
-
-The first argument is the receiver, the second one is the Ruby array
-which contains the arguments to the method.
-
-*Notice*: GC should know about global variables which refer to Ruby's objects,
-but are not exported to the Ruby world.  You need to protect them by
-
-  void rb_global_variable(VALUE *var)
-
-== Prepare extconf.rb
-
-If the file named extconf.rb exists, it will be executed to generate
-Makefile.
-
-extconf.rb is the file for checking compilation conditions etc.  You
-need to put
-
-  require 'mkmf'
-
-at the top of the file.  You can use the functions below to check
-various conditions.
-
-  have_macro(macro[, headers[, opt]]): check whether macro is defined
-  have_library(lib[, func[, headers[, opt]]]): check whether library containing function exists
-  find_library(lib[, func, *paths]): find library from paths
-  have_func(func[, headers[, opt]): check whether function exists
-  have_var(var[, headers[, opt]]): check whether variable exists
-  have_header(header[, preheaders[, opt]]): check whether header file exists
-  find_header(header, *paths): find header from paths
-  have_framework(fw): check whether framework exists (for MacOS X)
-  have_struct_member(type, member[, headers[, opt]]): check whether struct has member
-  have_type(type[, headers[, opt]]): check whether type exists
-  find_type(type, opt, *headers): check whether type exists in headers
-  have_const(const[, headers[, opt]]): check whether constant is defined
-  check_sizeof(type[, headers[, opts]]): check size of type
-  check_signedness(type[, headers[, opts]]): check signedness of type
-  convertible_int(type[, headers[, opts]]): find convertible integer type
-  find_executable(bin[, path]): find excutable file path
-  create_header(header): generate configured header
-  create_makefile(target[, target_prefix]): generate Makefile
-
-See MakeMakefile for full documentation of these functions.
-
-The value of the variables below will affect the Makefile.
-
-  $CFLAGS: included in CFLAGS make variable (such as -O)
-  $CPPFLAGS: included in CPPFLAGS make variable (such as -I, -D)
-  $LDFLAGS: included in LDFLAGS make variable (such as -L)
-  $objs: list of object file names
-
-Normally, the object files list is automatically generated by searching
-source files, but you must define them explicitly if any sources will
-be generated while building.
-
-If a compilation condition is not fulfilled, you should not call
-``create_makefile''.  The Makefile will not be generated, compilation will
-not be done.
-
-== Prepare Depend (Optional)
-
-If the file named depend exists, Makefile will include that file to
-check dependencies.  You can make this file by invoking
-
-  % gcc -MM *.c > depend
-
-It's harmless.  Prepare it.
-
-== Generate Makefile
-
-Try generating the Makefile by:
-
-  ruby extconf.rb
-
-If the library should be installed under vendor_ruby directory
-instead of site_ruby directory, use --vendor option as follows.
-
-  ruby extconf.rb --vendor
-
-You don't need this step if you put the extension library under the ext
-directory of the ruby source tree.  In that case, compilation of the
-interpreter will do this step for you.
-
-== Run make
-
-Type
-
-  make
-
-to compile your extension.  You don't need this step either if you have
-put the extension library under the ext directory of the ruby source tree.
-
-== Debug
-
-You may need to rb_debug the extension.  Extensions can be linked
-statically by adding the directory name in the ext/Setup file so that
-you can inspect the extension with the debugger.
-
-== Done! Now You Have the Extension Library
-
-You can do anything you want with your library.  The author of Ruby
-will not claim any restrictions on your code depending on the Ruby API.
-Feel free to use, modify, distribute or sell your program.

-
-== Types
-
-VALUE ::
-
-  The type for the Ruby object.  Actual structures are defined in ruby.h,
-  such as struct RString, etc.  To refer the values in structures, use
-  casting macros like RSTRING(obj).
-
-== Variables and Constants

-== C Pointer Wrapping
-
-Data_Wrap_Struct(VALUE klass, void (*mark)(), void (*free)(), void *sval) ::
-
-  Wrap a C pointer into a Ruby object.  If object has references to other
-  Ruby objects, they should be marked by using the mark function during
-  the GC process.  Otherwise, mark should be 0.  When this object is no
-  longer referred by anywhere, the pointer will be discarded by free
-  function.
-
-Data_Make_Struct(klass, type, mark, free, sval) ::

-  This macro allocates memory using malloc(), assigns it to the variable
-  sval, and returns the DATA encapsulating the pointer to memory region.

-
-SaveStringValue(value) ::
-
-  Checks that +value+ is a String and is not tainted
-
-== Data Type Conversion
-
-FIX2INT(value), INT2FIX(i) ::
-
-  Fixnum <-> integer
-
-FIX2LONG(value), LONG2FIX(l) ::
-
-  Fixnum <-> long
-

-
-NUM2ULONG(value), ULONG2NUM(ul) ::
-
-  Numeric <-> unsigned long
-
-NUM2LL(value), LL2NUM(ll) ::
-
-  Numeric <-> long long
-
-NUM2ULL(value), ULL2NUM(ull) ::

-
-  Object with #to_str -> pointer to String data
-
-StringValueCStr(value) ::
-
-  Object with #to_str -> pointer to String data without NULL bytes
-
-rb_str_new2(s) ::
-
-  char * -> String
-
-== Defining Class and Module
-
-VALUE rb_define_class(const char *name, VALUE super) ::
-
-  Defines a new Ruby class as a subclass of super.
-
-VALUE rb_define_class_under(VALUE module, const char *name, VALUE super) ::
-
-  Creates a new Ruby class as a subclass of super, under the module's
-  namespace.
-
-VALUE rb_define_module(const char *name) ::
-
-  Defines a new Ruby module.
-
-VALUE rb_define_module_under(VALUE module, const char *name) ::
-
-  Defines a new Ruby module under the module's namespace.

-  Extend the object with the module's attributes.
-
-== Defining Global Variables
-
-void rb_define_variable(const char *name, VALUE *var) ::

-  contains a character which is not allowed to be part of the symbol,
-  it can't be seen from Ruby programs.
-
-void rb_define_readonly_variable(const char *name, VALUE *var) ::
-
-  Defines a read-only global variable.  Works just like
-  rb_define_variable(), except the defined variable is read-only.
-
-void rb_define_virtual_variable(const char *name, VALUE (*getter)(), VALUE (*setter)()) ::
-
-  Defines a virtual variable, whose behavior is defined by a pair of C
-  functions.  The getter function is called when the variable is
-  referenced.  The setter function is called when the variable is set to a
-  value.  The prototype for getter/setter functions are:
-
-    VALUE getter(ID id)
-    void setter(VALUE val, ID id)
-
-  The getter function must return the value for the access.
-
-void rb_define_hooked_variable(const char *name, VALUE *var, VALUE (*getter)(), VALUE (*setter)()) ::
-
-  Defines hooked variable.  It's a virtual variable with a C variable.
-  The getter is called as
-
-    VALUE getter(ID id, VALUE *var)
-
-  returning a new value.  The setter is called as
-
-    void setter(VALUE val, ID id, VALUE *var)
-
-  GC requires C global variables which hold Ruby values to be marked.
-
-void rb_global_variable(VALUE *var)
-
-  Tells GC to protect these variables.
-
-== Constant Definition
-
-void rb_define_const(VALUE klass, const char *name, VALUE val) ::
-
-  Defines a new constant under the class/module.
-
-void rb_define_global_const(const char *name, VALUE val) ::
-
-  Defines a global constant.  This is just the same as
-
-    rb_define_const(cKernal, name, val)
-
-== Method Definition
-
-rb_define_method(VALUE klass, const char *name, VALUE (*func)(), int argc) ::
-
-  Defines a method for the class.  func is the function pointer.  argc
-  is the number of arguments.  if argc is -1, the function will receive
-  3 arguments: argc, argv, and self.  if argc is -2, the function will
-  receive 2 arguments, self and args, where args is a Ruby array of
-  the method arguments.
-
-rb_define_private_method(VALUE klass, const char *name, VALUE (*func)(), int argc) ::
-
-  Defines a private method for the class.  Arguments are same as
-  rb_define_method().
-
-rb_define_singleton_method(VALUE klass, const char *name, VALUE (*func)(), int argc) ::
-
-  Defines a singleton method.  Arguments are same as rb_define_method().
-
-rb_scan_args(int argc, VALUE *argv, const char *fmt, ...) ::
-
-  Retrieve argument from argc and argv to given VALUE references
-  according to the format string.  The format can be described in ABNF
-  as follows:
-
-    scan-arg-spec  := param-arg-spec [option-hash-arg-spec] [block-arg-spec]
-
-    param-arg-spec := pre-arg-spec [post-arg-spec] / post-arg-spec /
-                      pre-opt-post-arg-spec
-    pre-arg-spec   := num-of-leading-mandatory-args [num-of-optional-args]

-    num-of-trailing-mandatory-args := DIGIT ; The number of trailing

-    sym-for-option-hash-arg        := ":"   ; Indicates that an option
-                                            ; hash is captured if the last

-                                            ; given
-
-  For example, "12" means that the method requires at least one
-  argument, and at most receives three (1+2) arguments.  So, the format
-  string must be followed by three variable references, which are to be
-  assigned to captured arguments.  For omitted arguments, variables are
-  set to Qnil.  NULL can be put in place of a variable reference, which
-  means the corresponding captured argument(s) should be just dropped.
-
-  The number of given arguments, excluding an option hash or iterator
-  block, is returned.
-
-== Invoking Ruby method
-
-VALUE rb_funcall(VALUE recv, ID mid, int narg, ...) ::
-
-  Invokes a method.  To retrieve mid from a method name, use rb_intern().
-
-VALUE rb_funcall2(VALUE recv, ID mid, int argc, VALUE *argv) ::
-
-  Invokes a method, passing arguments by an array of values.
-
-VALUE rb_eval_string(const char *str) ::
-
-  Compiles and executes the string as a Ruby program.
-
-ID rb_intern(const char *name) ::
-
-  Returns ID corresponding to the name.
-
-char *rb_id2name(ID id) ::
-
-  Returns the name corresponding ID.
-
-char *rb_class2name(VALUE klass) ::
-
-  Returns the name of the class.
-
-int rb_respond_to(VALUE object, ID id) ::
-
-  Returns true if the object responds to the message specified by id.
-
-== Instance Variables
-
-VALUE rb_iv_get(VALUE obj, const char *name) ::
-
-  Retrieve the value of the instance variable.  If the name is not
-  prefixed by `@', that variable shall be inaccessible from Ruby.
-
-VALUE rb_iv_set(VALUE obj, const char *name, VALUE val) ::
-
-  Sets the value of the instance variable.
-
-== Control Structure
-
-VALUE rb_block_call(VALUE recv, ID mid, int argc, VALUE * argv, VALUE (*func) (ANYARGS), VALUE data2) ::
-
-  Calls a method on the recv, with the method name specified by the
-  symbol mid, with argc arguments in argv, supplying func as the
-  block. When func is called as the block, it will receive the value
-  from yield as the first argument, and data2 as the second argument.
-  When yielded with multiple values (in C, rb_yield_values(),
-  rb_yield_values2() and rb_yield_splat()), data2 is packed as an Array,
-  whereas yielded values can be gotten via argc/argv of the third/fourth
-  arguments.
-
-[OBSOLETE] VALUE rb_iterate(VALUE (*func1)(), void *arg1, VALUE (*func2)(), void *arg2) ::
-
-  Calls the function func1, supplying func2 as the block.  func1 will be
-  called with the argument arg1.  func2 receives the value from yield as
-  the first argument, arg2 as the second argument.
-
-  When rb_iterate is used in 1.9, func1 has to call some Ruby-level method.
-  This function is obsolete since 1.9; use rb_block_call instead.
-
-VALUE rb_yield(VALUE val) ::
-
-  Evaluates the block with value val.
-
-VALUE rb_rescue(VALUE (*func1)(), VALUE arg1, VALUE (*func2)(), VALUE arg2) ::
-
-  Calls the function func1, with arg1 as the argument.  If an exception
-  occurs during func1, it calls func2 with arg2 as the argument.  The
-  return value of rb_rescue() is the return value from func1 if no
-  exception occurs, from func2 otherwise.
-
-VALUE rb_ensure(VALUE (*func1)(), VALUE arg1, VALUE (*func2)(), VALUE arg2) ::
-
-  Calls the function func1 with arg1 as the argument, then calls func2
-  with arg2 if execution terminated.  The return value from
-  rb_ensure() is that of func1 when no exception occured.
-
-VALUE rb_protect(VALUE (*func) (VALUE), VALUE arg, int *state) ::
-
-  Calls the function func with arg as the argument.  If no exception
-  occured during func, it returns the result of func and *state is zero.
-  Otherwise, it returns Qnil and sets *state to nonzero.  If state is
-  NULL, it is not set in both cases.
-  You have to clear the error info with rb_set_errinfo(Qnil) when
-  ignoring the caught exception.
-
-void rb_jump_tag(int state) ::
-
-  Continues the exception caught by rb_protect() and rb_eval_string_protect().
-  state must be the returned value from those functions.  This function
-  never return to the caller.
-
-void rb_iter_break() ::
-
-  Exits from the current innermost block.  This function never return to
-  the caller.
-
-void rb_iter_break_value(VALUE value) ::
-
-  Exits from the current innermost block with the value.  The block will
-  return the given argument value.  This function never return to the
-  caller.
-
-== Exceptions and Errors
-
-void rb_warn(const char *fmt, ...) ::
-
-  Prints a warning message according to a printf-like format.
-
-void rb_warning(const char *fmt, ...) ::
-
-  Prints a warning message according to a printf-like format, if
-  $VERBOSE is true.
-
-void rb_raise(rb_eRuntimeError, const char *fmt, ...) ::
-
-  Raises RuntimeError.  The fmt is a format string just like printf().
-
-void rb_raise(VALUE exception, const char *fmt, ...) ::
-
-  Raises a class exception.  The fmt is a format string just like printf().
-
-void rb_fatal(const char *fmt, ...) ::
-
-  Raises a fatal error, terminates the interpreter.  No exception handling
-  will be done for fatal errors, but ensure blocks will be executed.
-
-void rb_bug(const char *fmt, ...) ::
-
-  Terminates the interpreter immediately.  This function should be
-  called under the situation caused by the bug in the interpreter.  No
-  exception handling nor ensure execution will be done.
-
-Note: In the format string, %i is used for Object#to_s (or Object#inspect if
-'+' flag is set) output (and related argument must be a VALUE).  For integers
-in format strings, use %d.
-
-== Initialize and Start the Interpreter
-
-The embedding API functions are below (not needed for extension libraries):
-
-void ruby_init() ::
-
-  Initializes the interpreter.
-
-void ruby_options(int argc, char **argv) ::
-
-  Process command line arguments for the interpreter.
-
-void ruby_run() ::
-
-  Starts execution of the interpreter.
-
-void ruby_script(char *name) ::
-

-
-  void rb_add_event_hook(rb_event_hook_func_t func, rb_event_flag_t events,
-                         VALUE data)
-
-Adds a hook function for the specified interpreter events.
-events should be OR'ed value of:
-
-  RUBY_EVENT_LINE
-  RUBY_EVENT_CLASS
-  RUBY_EVENT_END
-  RUBY_EVENT_CALL
-  RUBY_EVENT_RETURN
-  RUBY_EVENT_C_CALL
-  RUBY_EVENT_C_RETURN
-  RUBY_EVENT_RAISE
-  RUBY_EVENT_ALL
-
-The definition of rb_event_hook_func_t is below:
-
-  typedef void (*rb_event_hook_func_t)(rb_event_t event, VALUE data,
-                                       VALUE self, ID id, VALUE klass)
-
-The third argument `data' to rb_add_event_hook() is passed to the hook
-function as the second argument, which was the pointer to the current
-NODE in 1.8.  See RB_EVENT_HOOKS_HAVE_CALLBACK_DATA below.
-
-  int rb_remove_event_hook(rb_event_hook_func_t func)
-
-Removes the specified hook function.
-
-== Macros for Compatibility
-

-
-USE_SYMBOL_AS_METHOD_NAME ::
-
-  Means that Symbols will be returned as method names, e.g.,
-  Module#methods, #singleton_methods and so on.
-
-HAVE_RUBY_*_H ::
-
-  Defined in ruby.h and means corresponding header is available.  For
-  instance, when HAVE_RUBY_ST_H is defined you should use ruby/st.h not
-  mere st.h.
-
-RB_EVENT_HOOKS_HAVE_CALLBACK_DATA ::
-
-  Means that rb_add_event_hook() takes the third argument `data', to be
-  passed to the given event hook function.

-Rubyの拡張ライブラリの作り方を説明します．
-
-= 基礎知識
-
-Cの変数には型があり，データには型がありません．ですから，た
-とえばポインタをintの変数に代入すると，その値は整数として取
-り扱われます．逆にRubyの変数には型がなく，データに型がありま
-す．この違いのため，CとRubyは相互に変換しなければ，お互いの
-データをアクセスできません．
-
-RubyのデータはVALUEというCの型で表現されます．VALUE型のデー
-タはそのデータタイプを自分で知っています．このデータタイプと
-いうのはデータ(オブジェクト)の実際の構造を意味していて，Ruby
-のクラスとはまた違ったものです．
-
-VALUEからCにとって意味のあるデータを取り出すためには
-
-1. VALUEのデータタイプを知る
-2. VALUEをCのデータに変換する
-
-の両方が必要です．(1)を忘れると間違ったデータの変換が行われ
-て，最悪プログラムがcore dumpします．
-
-== データタイプ
-
-Rubyにはユーザが使う可能性のある以下のタイプがあります．
-
-T_NIL      :: nil
-T_OBJECT   :: 通常のオブジェクト
-T_CLASS    :: クラス
-T_MODULE   :: モジュール
-T_FLOAT    :: 浮動小数点数
-T_STRING   :: 文字列
-T_REGEXP   :: 正規表現
-T_ARRAY    :: 配列
-T_HASH     :: 連想配列
-T_STRUCT   :: (Rubyの)構造体
-T_BIGNUM   :: 多倍長整数
-T_FIXNUM   :: Fixnum(31bitまたは63bit長整数)
-T_COMPLEX  :: 複素数
-T_RATIONAL :: 有理数
-T_FILE     :: 入出力
-T_TRUE     :: 真
-T_FALSE    :: 偽
-T_DATA     :: データ
-T_SYMBOL   :: シンボル
-
-その他に内部で利用されている以下のタイプがあります．
-
-  T_ICLASS
-  T_MATCH
-  T_UNDEF
-  T_NODE
-  T_ZOMBIE
-
-ほとんどのタイプはCの構造体で実装されています．
-
-== VALUEのデータタイプをチェックする
-
-ruby.hではTYPE()というマクロが定義されていて，VALUEのデータ
-タイプを知ることが出来ます．TYPE()マクロは上で紹介したT_XXXX
-の形式の定数を返します．VALUEのデータタイプに応じて処理する
-場合には，TYPE()の値で分岐することになります．
-
-  switch (TYPE(obj)) {
-    case T_FIXNUM:
-      /* FIXNUMの処理 */
-      break;
-    case T_STRING:
-      /* 文字列の処理 */
-      break;
-    case T_ARRAY:
-      /* 配列の処理 */
-      break;
-    default:
-      /* 例外を発生させる */
-      rb_raise(rb_eTypeError, "not valid value");
-      break;
-  }
-
-それとデータタイプをチェックして，正しくなければ例外を発生す
-る関数が用意されています．
-
-  void Check_Type(VALUE value, int type)
-
-この関数はvalueがtypeで無ければ，例外を発生させます．引数と
-して与えられたVALUEのデータタイプが正しいかどうかチェックす
-るためには，この関数を使います．
-
-FIXNUMとNILに関してはより高速な判別マクロが用意されています．
-
-  FIXNUM_P(obj)
-  NIL_P(obj)
-
-== VALUEをCのデータに変換する
-
-データタイプがT_NIL，T_FALSE，T_TRUEである時，データはそれぞ
-れnil，false，trueです．このデータタイプのオブジェクトはひと
-つずつしか存在しません．
-
-データタイプがT_FIXNUMの時，これは31bitまたは63bitのサイズを
-持つ整数です．longのサイズが32bitのプラットフォームであれば
-31bitに，longのサイズが64bitのプラットフォームであれば63bit
-になります. FIXNUM を C の整数に変換するためにはマクロ
-「FIX2INT()」または「FIX2LONG()」を使います．これらのマクロ
-を使用する際には事前にデータタイプがFIXNUMであることを確認す
-る必要がありますが，比較的高速に変換を行うことができます．ま
-た，「FIX2LONG()」は例外を発生しませんが，「FIX2INT()」は変
-換結果がintのサイズに収まらない場合には例外を発生します．
-それから，FIXNUMに限らずRubyのデータを整数に変換する
-「NUM2INT()」および「NUM2LONG()」というマクロがあります．こ
-れらのマクロはマクロはデータタイプのチェック無しで使えます
-(整数に変換できない場合には例外が発生する)．同様にチェック無
-で使える変換マクロはdoubleを取り出す「NUM2DBL()」があります．
-
-char* を取り出す場合， StringValue() と StringValuePtr()
-を使います．
-StringValue(var) は var が String
-であれば何もせず，そうでなければ var を var.to_str() の結果
-に置き換えるマクロ，StringValuePtr(var) は同様に var を
-String に置き換えてから var のバイト列表現に対する char* を
-返すマクロです．var の内容を直接置き換える処理が入るので，
-var は lvalue である必要があります．
-また，StringValuePtr() に類似した StringValueCStr() というマ
-クロもあります．StringValueCStr(var) は var を String に置き
-換えてから var の文字列表現に対する char* を返します．返され
-る文字列の末尾には nul 文字が付加されます．なお，途中に nul
-文字が含まれる場合は ArgumentError が発生します．
-一方，StringValuePtr() では，末尾に nul 文字がある保証はなく，
-途中に nul 文字が含まれている可能性もあります．
-
-それ以外のデータタイプは対応するCの構造体があります．対応す
-る構造体のあるVALUEはそのままキャスト(型変換)すれば構造体の
-ポインタに変換できます．
-
-構造体は「struct RXxxxx」という名前でruby.hで定義されていま
-す．例えば文字列は「struct RString」です．実際に使う可能性が
-あるのは文字列と配列くらいだと思います．
-
-ruby.hでは構造体へキャストするマクロも「RXXXXX()」(全部大文
-字にしたもの)という名前で提供されています(例: RSTRING())．
-
-構造体からデータを取り出すマクロが提供されています．文字列
-strの長さを得るためには「RSTRING_LEN(str)」とし，文字列strを
-char*として得るためには「RSTRING_PTR(str)」とします．配列の
-場合には，それぞれ「RARRAY_LEN(ary)」，「RARRAY_PTR(ary)」と
-なります．
-
-Rubyの構造体を直接アクセスする時に気をつけなければならないこ
-とは，配列や文字列の構造体の中身は参照するだけで，直接変更し
-ないことです．直接変更した場合，オブジェクトの内容の整合性が
-とれなくなって，思わぬバグの原因になります．
-
-== CのデータをVALUEに変換する
-
-VALUEの実際の構造は
-
-FIXNUMの場合 ::
-
-  1bit左シフトして，LSBを立てる．
-
-その他のポインタの場合 ::
-
-  そのままVALUEにキャストする．
-
-となっています．よって，LSBをチェックすればVALUEがFIXNUMかど
-うかわかるわけです(ポインタのLSBが立っていないことを仮定して
-いる)．
-
-ですから，FIXNUM以外のRubyのオブジェクトの構造体は単にVALUE
-にキャストするだけでVALUEに変換出来ます．ただし，任意の構造
-体がVALUEにキャスト出来るわけではありません．キャストするの
-はRubyの知っている構造体(ruby.hで定義されているstruct RXxxx
-のもの)だけです．
-
-FIXNUMに関しては変換マクロを経由する必要があります．Cの整数
-からVALUEに変換するマクロは以下のものがあります．必要に応じ
-て使い分けてください．
-
-INT2FIX() :: もとの整数が31bitまたは63bit以内に収まる自信
-      	     がある時
-INT2NUM() :: 任意の整数からVALUEへ
-
-INT2NUM()は整数がFIXNUMの範囲に収まらない場合，Bignumに変換
-してくれます(が，少し遅い)．
-
-== Rubyのデータを操作する
-
-先程も述べた通り，Rubyの構造体をアクセスする時に内容の更新を
-行うことは勧められません．で，Rubyのデータを操作する時には
-Rubyが用意している関数を用いてください．
-
-ここではもっとも使われるであろう文字列と配列の生成/操作を行
-い関数をあげます(全部ではないです)．
-
-=== 文字列に対する関数
-
-rb_str_new(const char *ptr, long len) ::
-
-  新しいRubyの文字列を生成する．
-
-rb_str_new2(const char *ptr)

-  rb_str_new(ptr, strlen(ptr))と同等である．
-
-rb_tainted_str_new(const char *ptr, long len)
-
-  汚染マークが付加された新しいRubyの文字列を生成する．外部
-  からのデータに基づく文字列には汚染マークが付加されるべき

-  整形し，Rubyの文字列を生成する．
-
-  注意: %iはObject#to_s('+'フラグが指定されているときはObject#inspect)を
-  使ったVALUEの出力に使用されているため，整数には%dを使用すること．
-
-rb_str_cat(VALUE str, const char *ptr, long len)
-
-  Rubyの文字列strにlenバイトの文字列ptrを追加する．
-
-rb_str_cat2(VALUE str, const char* ptr)

-rb_str_catf(VALUE str, const char* format, ...)
-rb_str_vcatf(VALUE str, const char* format, va_list ap)
-
-  Cの文字列formatと続く引数をprintf(3)のフォーマットにしたがって
-  整形し，Rubyの文字列strに追加する．この関数の機能は，それぞれ
-  rb_str_cat2(str, rb_sprintf(format, ...)) や
-  rb_str_cat2(str, rb_vsprintf(format, ap)) と同等である．
-
-rb_enc_str_new(const char *ptr, long len, rb_encoding *enc)
-
-  指定されたエンコーディングでRubyの文字列を生成する.
-
-rb_usascii_str_new(const char *ptr, long len)
-rb_usascii_str_new_cstr(const char *ptr)
-
-  エンコーディングがUS-ASCIIのRubyの文字列を生成する.
-
-rb_str_resize(VALUE str, long len)
-
-  Rubyの文字列のサイズをlenバイトに変更する．strの長さは前
-  以てセットされていなければならない．lenが元の長さよりも短
-  い時は，lenバイトを越えた部分の内容は捨てられる．lenが元
-  の長さよりも長い時は，元の長さを越えた部分の内容は保存さ
-  れないでゴミになるだろう．この関数の呼び出しによって
-  RSTRING_PTR(str)が変更されるかもしれないことに注意．
-
-rb_str_set_len(VALUE str, long len)
-
-  Rubyの文字列のサイズをlenバイトにセットする．strが変更可
-  能でなければ例外が発生する．RSTRING_LEN(str)とは無関係に，
-  lenバイトまでの内容は保存される．lenはstrの容量を越えてい
-  てはならない．
-
-
-== 配列に対する関数
-
-rb_ary_new()
-
-  要素が0の配列を生成する．
-

-
-rb_ary_new4(long n, VALUE *elts)
-
-  配列で与えたn要素の配列を生成する．
-
-rb_ary_to_ary(VALUE obj)

-引数aryに配列を渡さなければならない. さもないと
-コアを吐く.
-
-rb_ary_aref(argc, VALUE *argv, VALUE ary)
-
-  Array#[]と同等.
-
-rb_ary_entry(VALUE ary, long offset)

-rb_ary_pop(VALUE ary)
-rb_ary_shift(VALUE ary)
-rb_ary_unshift(VALUE ary, VALUE val)
-
-rb_ary_cat(VALUE ary, const VALUE *ptr, long len)

-= Rubyの機能を使う
-
-原理的にRubyで書けることはCでも書けます．RubyそのものがCで記
-述されているんですから，当然といえば当然なんですけど．ここで

-
-== Rubyに機能を追加する

-では順に紹介します．
-
-=== クラス/モジュール定義
-
-クラスやモジュールを定義するためには，以下の関数を使います．
-
-  VALUE rb_define_class(const char *name, VALUE super)
-  VALUE rb_define_module(const char *name)
-
-これらの関数は新しく定義されたクラスやモジュールを返します．
-メソッドや定数の定義にこれらの値が必要なので，ほとんどの場合
-は戻り値を変数に格納しておく必要があるでしょう．
-
-クラスやモジュールを他のクラスの内部にネストして定義する時に
-は以下の関数を使います．
-
-  VALUE rb_define_class_under(VALUE outer, const char *name, VALUE super)
-  VALUE rb_define_module_under(VALUE outer, const char *name)
-
-=== メソッド/特異メソッド定義
-
-メソッドや特異メソッドを定義するには以下の関数を使います．
-
-  void rb_define_method(VALUE klass, const char *name,
-                        VALUE (*func)(), int argc)
-
-  void rb_define_singleton_method(VALUE object, const char *name,
-                                  VALUE (*func)(), int argc)
-
-
-念のため説明すると「特異メソッド」とは，その特定のオブジェク
-トに対してだけ有効なメソッドです．RubyではよくSmalltalkにお
-けるクラスメソッドとして，クラスに対する特異メソッドが使われ
-ます．
-
-これらの関数の argcという引数はCの関数へ渡される引数の数(と
-形式)を決めます．argcが0以上の時は関数に引き渡す引数の数を意
-味します．16個以上の引数は使えません(が，要りませんよね，そ
-んなに)．実際の関数には先頭の引数としてselfが与えられますの
-で，指定した数より1多い引数を持つことになります．
-
-argcが負の時は引数の数ではなく，形式を指定したことになります．
-argcが-1の時は引数を配列に入れて渡されます．argcが-2の時は引
-数はRubyの配列として渡されます．
-
-メソッドを定義する関数はまだいくつかあります. ひとつはメソッド
-名としてIDを取ります. IDについては2.2.2を参照.
-
-  void rb_define_method_id(VALUE klass, ID name,
-                           VALUE (*func)(ANYARGS), int argc)
-
-private/protectedなメソッドを定義するふたつの関数があります.
-
-  void rb_define_private_method(VALUE klass, const char *name,
-				VALUE (*func)(), int argc)
-  void rb_define_protected_method(VALUE klass, const char *name,
-			          VALUE (*func)(), int argc)
-
-privateメソッドとは関数形式でしか呼び出すことの出来ないメソッ
-ドです．
-
-最後に， rb_define_module関数はモジュール関数を定義します．
-モジュール関数とはモジュールの特異メソッドであり，同時に
-privateメソッドでもあるものです．例をあげるとMathモジュール
-のsqrt()などがあげられます．このメソッドは
-
-  Math.sqrt(4)
-
-という形式でも
-
-  include Math
-  sqrt(4)
-
-という形式でも使えます．モジュール関数を定義する関数は以下の
-通りです．
-
-  void rb_define_module_function(VALUE module, const char *name,
-		                 VALUE (*func)(), int argc)
-
-関数的メソッド(Kernelモジュールのprivate method)を定義するた
-めの関数は以下の通りです．
-
-  void rb_define_global_function(const char *name, VALUE (*func)(), int argc)
-
-
-メソッドの別名を定義するための関数は以下の通りです．
-
-  void rb_define_alias(VALUE module, const char* new, const char* old);
-
-属性の取得・設定メソッドを定義するには
-
-  void rb_define_attr(VALUE klass, const char *name, int read, int write)
-
-クラスメソッドallocateを定義したり削除したりするための関数は
-以下の通りです．
-
-  void rb_define_alloc_func(VALUE klass, VALUE (*func)(VALUE klass));
-  void rb_undef_alloc_func(VALUE klass);
-
-funcはクラスを引数として受け取って，新しく割り当てられたイン
-スタンスを返さなくてはなりません．このインスタンスは，外部リ
-ソースなどを含まない，できるだけ「空」のままにしておいたほう
-がよいでしょう．
-
-=== 定数定義
-
-拡張ライブラリが必要な定数はあらかじめ定義しておいた方が良い
-でしょう．定数を定義する関数は二つあります．
-
-  void rb_define_const(VALUE klass, const char *name, VALUE val)
-  void rb_define_global_const(const char *name, VALUE val)
-
-前者は特定のクラス/モジュールに属する定数を定義するもの，後
-者はグローバルな定数を定義するものです．
-
-== Rubyの機能をCから呼び出す
-
-既に『1.5 Rubyのデータを操作する』で一部紹介したような関数を
-使えば，Rubyの機能を実現している関数を直接呼び出すことが出来
-ます．
-
-# このような関数の一覧表はいまのところありません．ソースを見
-# るしかないですね．
-
-それ以外にもRubyの機能を呼び出す方法はいくつかあります．
-
-=== Rubyのプログラムをevalする
-
-CからRubyの機能を呼び出すもっとも簡単な方法として，文字列で
-与えられたRubyのプログラムを評価する以下の関数があります．
-
-  VALUE rb_eval_string(const char *str)
-
-この評価は現在の環境で行われます．つまり，現在のローカル変数
-などを受け継ぎます．
-
-評価は例外を発生するかもしれないことに注意しましょう. より安全
-な関数もあります.
-
-  VALUE rb_eval_string_protect(const char *str, int *state)
-
-この関数はエラーが発生するとnilを返します．そして，成功時には
-*stateはゼロに，さもなくば非ゼロになります．
-
-=== IDまたはシンボル
-
-Cから文字列を経由せずにRubyのメソッドを呼び出すこともできま
-す．その前に，Rubyインタプリタ内でメソッドや変数名を指定する
-時に使われているIDについて説明しておきましょう．
-
-IDとは変数名，メソッド名を表す整数です．Rubyの中では
-
- :識別子
-
-または
-
- :"任意の文字列"
-
-でアクセスできます．Cからこの整数を得るためには関数
-
-  rb_intern(const char *name)
-  rb_intern_str(VALUE name)
-
-を使います．Rubyから引数として与えられたシンボル(または文字
-列)をIDに変換するには以下の関数を使います．
-
-  rb_to_id(VALUE symbol)
-  rb_check_id(volatile VALUE *name)
-  rb_check_id_cstr(const char *name, long len, rb_encoding *enc)
-
-もし引数がシンボルでも文字列でもなければ、to_strメソッドで文
-字列に変換しようとします．第二の関数はその変換結果を*nameに保
-存し,その名前が既知のシンボルでない場合は0を返します．この関
-数が0以外を返した場合は*nameは常にシンボルか文字列であり、0を
-返した場合は常に文字列です．第三の関数はRubyの文字列ではなく
-NUL終端されたCの文字列を使います．
-
-=== CからRubyのメソッドを呼び出す
-
-Cから文字列を経由せずにRubyのメソッドを呼び出すためには以下
-の関数を使います．
-
-  VALUE rb_funcall(VALUE recv, ID mid, int argc, ...)
-
-この関数はオブジェクトrecvのmidで指定されるメソッドを呼び出
-します．その他に引数の指定の仕方が違う以下の関数もあります．
-
-  VALUE rb_funcall2(VALUE recv, ID mid, int argc, VALUE *argv)
-  VALUE rb_apply(VALUE recv, ID mid, VALUE args)
-
-applyには引数としてRubyの配列を与えます．
-
-=== 変数/定数を参照/更新する
-
-Cから関数を使って参照・更新できるのは，定数，インスタンス変
-数です．大域変数は一部のものはCの大域変数としてアクセスでき
-ます．ローカル変数を参照する方法は公開していません．
-
-オブジェクトのインスタンス変数を参照・更新する関数は以下の通
-りです．
-
-  VALUE rb_ivar_get(VALUE obj, ID id)
-  VALUE rb_ivar_set(VALUE obj, ID id, VALUE val)
-
-idはrb_intern()で得られるものを使ってください．
-
-定数を参照するには以下の関数を使ってください．
-
-  VALUE rb_const_get(VALUE obj, ID id)
-
-定数を新しく定義するためには『2.1.3 定数定義』で紹介さ
-れている関数を使ってください．
-
-= RubyとCとの情報共有
-
-C言語とRubyの間で情報を共有する方法について解説します．
-
-== Cから参照できるRubyの定数
-
-以下のRubyの定数はCのレベルから参照できます．
-
-  Qtrue
-  Qfalse
-
-真偽値．QfalseはC言語でも偽とみなされます(つまり0)．
-
-  Qnil
-
-C言語から見た「nil」．
-
-== CとRubyで共有される大域変数
-
-CとRubyで大域変数を使って情報を共有できます．共有できる大域
-変数にはいくつかの種類があります．そのなかでもっとも良く使わ
-れると思われるのはrb_define_variable()です．
-
-  void rb_define_variable(const char *name, VALUE *var)
-
-この関数はRubyとCとで共有する大域変数を定義します．変数名が
-`$'で始まらない時には自動的に追加されます．この変数の値を変
-更すると自動的にRubyの対応する変数の値も変わります．
-
-またRuby側からは更新できない変数もあります．このread onlyの
-変数は以下の関数で定義します．
-
-  void rb_define_readonly_variable(const char *name, VALUE *var)
-
-これら変数の他にhookをつけた大域変数を定義できます．hook付き
-の大域変数は以下の関数を用いて定義します．hook付き大域変数の
-値の参照や設定はhookで行う必要があります．
-
-  void rb_define_hooked_variable(const char *name, VALUE *var,
-				 VALUE (*getter)(), void (*setter)())
-
-この関数はCの関数によってhookのつけられた大域変数を定義しま
-す．変数が参照された時には関数getterが，変数に値がセットされ
-た時には関数setterが呼ばれる．hookを指定しない場合はgetterや
-setterに0を指定します．
-# getterもsetterも0ならばrb_define_variable()と同じになる．
-
-getterとsetterの仕様は次の通りです．
-
-  VALUE (*getter)(ID id, VALUE *var);
-  void (*setter)(VALUE val, ID id, VALUE *var);
-
-
-それから，対応するCの変数を持たないRubyの大域変数を定義する
-こともできます. その変数の値はフック関数のみによって取得・設定
-されます.
-
-  void rb_define_virtual_variable(const char *name,
-				  VALUE (*getter)(), void (*setter)())
-
-この関数によって定義されたRubyの大域変数が参照された時には
-getterが，変数に値がセットされた時にはsetterが呼ばれます．
-
-getterとsetterの仕様は以下の通りです．
-
-  (*getter)(ID id);
-  (*setter)(VALUE val, ID id);
-
-== CのデータをRubyオブジェクトにする
-
-Cの世界で定義されたデータ(構造体)をRubyのオブジェクトとして
-取り扱いたい場合がありえます．このような場合には，Dataという
-RubyオブジェクトにCの構造体(へのポインタ)をくるむことでRuby
-オブジェクトとして取り扱えるようになります．
-
-Dataオブジェクトを生成して構造体をRubyオブジェクトにカプセル
-化するためには，以下のマクロを使います．
-
-  Data_Wrap_Struct(klass, mark, free, sval)
-
-このマクロの戻り値は生成されたDataオブジェクトです．
-
-klassはこのDataオブジェクトのクラスです．markはこの構造体が
-Rubyのオブジェクトへの参照がある時に使う関数です．そのような
-参照を含まない時には0を指定します．
-
-# そのような参照は勧められません．
-
-freeはこの構造体がもう不要になった時に呼ばれる関数です．この
-関数がガーベージコレクタから呼ばれます．これが-1の場合は，単
-純に開放されます．
-
-markおよびfree関数はGC実行中に呼び出されます.
-なお, GC実行中はRubyオブジェクトのアロケーションは禁止されま
-す. よって, markおよびfree関数でRubyオブジェクトのアロケーシ
-ョンは行わないでください.
-
-Cの構造体の割当とDataオブジェクトの生成を同時に行うマクロと
-して以下のものが提供されています．
-
-  Data_Make_Struct(klass, type, mark, free, sval)
-
-このマクロの戻り値は生成されたDataオブジェクトです．このマク
-ロは以下の式のように働きます:
-
-  (sval = ALLOC(type), Data_Wrap_Struct(klass, mark, free, sval))
-
-klass, mark, freeはData_Wrap_Structと同じ働きをします．type
-は割り当てるC構造体の型です．割り当てられた構造体は変数sval
-に代入されます．この変数の型は (type*) である必要があります．
-
-Dataオブジェクトからポインタを取り出すのは以下のマクロを用い
-ます．
-
-  Data_Get_Struct(obj, type, sval)
-
-Cの構造体へのポインタは変数svalに代入されます．
-
-これらのDataの使い方はちょっと分かりにくいので，後で説明する
-例題を参照してください．
-
-= 例題 - dbmパッケージを作る
-
-ここまでの説明でとりあえず拡張ライブラリは作れるはずです．
-Rubyのextディレクトリにすでに含まれているdbmライブラリを例に
-して段階的に説明します．
-
-== ディレクトリを作る
-
-  % mkdir ext/dbm
-
-Ruby 1.1からは任意のディレクトリでダイナミックライブラリを作
-ることができるようになりました．Rubyに静的にリンクする場合に
-はRubyを展開したディレクトリの下，extディレクトリの中に拡張
-ライブラリ用のディレクトリを作る必要があります．名前は適当に
-選んで構いません．
-
-== 設計する
-
-まあ，当然なんですけど，どういう機能を実現するかどうかまず設
-計する必要があります．どんなクラスをつくるか，そのクラスには
-どんなメソッドがあるか，クラスが提供する定数などについて設計
-します．
-
-== Cコードを書く
-
-拡張ライブラリ本体となるC言語のソースを書きます．C言語のソー
-スがひとつの時には「ライブラリ名.c」を選ぶと良いでしょう．C
-言語のソースが複数の場合には逆に「ライブラリ名.c」というファ
-イル名は避ける必要があります．オブジェクトファイルとモジュー
-ル生成時に中間的に生成される「ライブラリ名.o」というファイル
-とが衝突するからです．また，後述する mkmf ライブラリのいくつ
-かの関数がコンパイルを要するテストのために「conftest.c」とい
-うファイル名を使用することに注意してください．ソースファイル
-名として「conftest.c」を使用してはなりません．
-
-Rubyは拡張ライブラリをロードする時に「Init_ライブラリ名」と
-いう関数を自動的に実行します．dbmライブラリの場合「Init_dbm」
-です．この関数の中でクラス，モジュール，メソッド，定数などの
-定義を行います．dbm.cから一部引用します．
-
-  void
-  Init_dbm(void)
-  {
-      /* DBMクラスを定義する */
-      cDBM = rb_define_class("DBM", rb_cObject);
-      /* DBMはEnumerateモジュールをインクルードする */
-      rb_include_module(cDBM, rb_mEnumerable);
-  
-      /* DBMクラスのクラスメソッドopen(): 引数はCの配列で受ける */
-      rb_define_singleton_method(cDBM, "open", fdbm_s_open, -1);
-  
-      /* DBMクラスのメソッドclose(): 引数はなし */
-      rb_define_method(cDBM, "close", fdbm_close, 0);
-      /* DBMクラスのメソッド[]: 引数は1個 */
-      rb_define_method(cDBM, "[]", fdbm_fetch, 1);
-
-      /* ... */
-  
-      /* DBMデータを格納するインスタンス変数名のためのID */
-      id_dbm = rb_intern("dbm");
-  }
-
-DBMライブラリはdbmのデータと対応するオブジェクトになるはずで
-すから，Cの世界のdbmをRubyの世界に取り込む必要があります．
-
-dbm.cではData_Make_Structを以下のように使っています．
-
-  struct dbmdata {
-      int  di_size;
-      DBM *di_dbm;
-  };
-  
-  
-  obj = Data_Make_Struct(klass, struct dbmdata, 0, free_dbm, dbmp);
-
-ここではdbmstruct構造体へのポインタをDataにカプセル化してい
-ます．DBM*を直接カプセル化しないのはclose()した時の処理を考
-えてのことです．
-
-Dataオブジェクトからdbmstruct構造体のポインタを取り出すため
-に以下のマクロを使っています．
-
-  #define GetDBM(obj, dbmp) {\
-      Data_Get_Struct(obj, struct dbmdata, dbmp);\
-      if (dbmp->di_dbm == 0) closed_dbm();\
-  }
-
-ちょっと複雑なマクロですが，要するにdbmdata構造体のポインタ
-の取り出しと，closeされているかどうかのチェックをまとめてい
-るだけです．
-
-DBMクラスにはたくさんメソッドがありますが，分類すると3種類の
-引数の受け方があります．ひとつは引数の数が固定のもので，例と
-してはdeleteメソッドがあります．deleteメソッドを実装している
-fdbm_delete()はこのようになっています．
-
-  static VALUE
-  fdbm_delete(VALUE obj, VALUE keystr)
-  {
-      /* ... */
-  }
-
-引数の数が固定のタイプは第1引数がself，第2引数以降がメソッド
-の引数となります．
-
-引数の数が不定のものはCの配列で受けるものとRubyの配列で受け
-るものとがあります．dbmライブラリの中で，Cの配列で受けるもの
-はDBMのクラスメソッドであるopen()です．これを実装している関
-数fdbm_s_open()はこうなっています．
-
-  static VALUE
-  fdbm_s_open(int argc, VALUE *argv, VALUE klass)
-  {
-      /* ... */
-
-      if (rb_scan_args(argc, argv, "11", &file, &vmode) == 1) {
-  	mode = 0666;		/* default value */
-      }
-
-      /* ... */
-  }
-
-このタイプの関数は第1引数が与えられた引数の数，第2引数が与え
-られた引数の入っている配列になります．selfは第3引数として与
-えられます．
-
-この配列で与えられた引数を解析するための関数がopen()でも使わ
-れているrb_scan_args()です．第3引数に指定したフォーマットに従
-い，第4変数以降に指定したVALUEへの参照に値を代入してくれま
-す．
-
-
-引数をRubyの配列として受け取るメソッドの例には
-Thread#initializeがあります．実装はこうです．
-
-  static VALUE
-  thread_initialize(VALUE thread, VALUE args)
-  {
-      /* ... */
-  }
-
-第1引数はself，第2引数はRubyの配列です．
-
-*注意事項*
-
-Rubyと共有はしないがRubyのオブジェクトを格納する可能性のある
-Cの大域変数は以下の関数を使ってRubyインタプリタに変数の存在
-を教えてあげてください．でないとGCでトラブルを起こします．
-
-  void rb_global_variable(VALUE *var)
-
-== extconf.rbを用意する
-
-Makefileを作る場合の雛型になるextconf.rbというファイルを作り
-ます．extconf.rbはライブラリのコンパイルに必要な条件のチェッ
-クなどを行うことが目的です．まず，
-
-  require 'mkmf'
-
-をextconf.rbの先頭に置きます．extconf.rbの中では以下のRuby関
-数を使うことが出来ます．
-
-  have_library(lib, func): ライブラリの存在チェック
-  have_func(func, header): 関数の存在チェック
-  have_header(header): ヘッダファイルの存在チェック
-  create_makefile(target[, target_prefix]): Makefileの生成
-
-以下の変数を使うことができます．
-
-  $CFLAGS: コンパイル時に追加的に指定するフラグ(-Oなど)
-  $CPPFLAGS: プリプロセッサに追加的に指定するフラグ(-Iや-Dなど)
-  $LDFLAGS: リンク時に追加的に指定するフラグ(-Lなど)
-  $objs: リンクされるオブジェクトファイル名のリスト
-
-オブジェクトファイルのリストは，通常はソースファイルを検索し
-て自動的に生成されますが，makeの途中でソースを生成するような
-場合は明示的に指定する必要があります．
-
-ライブラリをコンパイルする条件が揃わず，そのライブラリをコン
-パイルしない時にはcreate_makefileを呼ばなければMakefileは生
-成されず，コンパイルも行われません．
-
-== dependを用意する
-
-もし，ディレクトリにdependというファイルが存在すれば，
-Makefileが依存関係をチェックしてくれます．
-
-  % gcc -MM *.c > depend
-
-などで作ることが出来ます．あって損は無いでしょう．
-
-== Makefileを生成する
-
-Makefileを実際に生成するためには
-
-  ruby extconf.rb
-
-とします．extconf.rbに require 'mkmf' の行がない場合にはエラー
-になりますので，引数を追加して
-
-  ruby -r mkmf extconf.rb
-
-としてください．
-
-site_ruby ディレクトリでなく，
-vendor_ruby ディレクトリにインストールする場合には
-以下のように --vendor オプションを加えてください．
-
-  ruby extconf.rb --vendor
-
-ディレクトリをext以下に用意した場合にはRuby全体のmakeの時に
-自動的にMakefileが生成されますので，このステップは不要です．
-
-== makeする
-
-動的リンクライブラリを生成する場合にはその場でmakeしてくださ
-い．必要であれば make install でインストールされます．
-
-ext以下にディレクトリを用意した場合は，Rubyのディレクトリで
-makeを実行するとMakefileを生成からmake，必要によってはそのモ
-ジュールのRubyへのリンクまで自動的に実行してくれます．
-extconf.rbを書き換えるなどしてMakefileの再生成が必要な時はま
-たRubyディレクトリでmakeしてください．
-
-拡張ライブラリはmake installでRubyライブラリのディレクトリの
-下にコピーされます．もし拡張ライブラリと協調して使うRubyで記
-述されたプログラムがあり，Rubyライブラリに置きたい場合には，
-拡張ライブラリ用のディレクトリの下に lib というディレクトリ
-を作り，そこに 拡張子 .rb のファイルを置いておけば同時にイン
-ストールされます．
-
-== デバッグ
-
-まあ，デバッグしないと動かないでしょうね．ext/Setupにディレ
-クトリ名を書くと静的にリンクするのでデバッガが使えるようにな
-ります．その分コンパイルが遅くなりますけど．
-
-== できあがり
-
-後はこっそり使うなり，広く公開するなり，売るなり，ご自由にお
-使いください．Rubyの作者は拡張ライブラリに関して一切の権利を
-主張しません．

+# Rubyとは
+
+Rubyはシンプルかつ強力なオブジェクト指向スクリプト言語です． Rubyは純粋なオブジェクト指向言語として設計されているので，
+オブジェクト指向プログラミングを手軽に行う事が出来ます．もちろん普通の手続き型のプログラミングも可能です．
+
+Rubyはテキスト処理関係の能力などに優れ，Perlと同じくらい強力です．さらにシンプルな文法と，
+例外処理やイテレータなどの機構によって，より分かりやすいプログラミングが出来ます．
+
+## Rubyの特長
+
+*   シンプルな文法
+*   普通のオブジェクト指向機能(クラス，メソッドコールなど)
+*   特殊なオブジェクト指向機能(Mixin, 特異メソッドなど)
+*   演算子オーバーロード
+*   例外処理機能
+*   イテレータとクロージャ
+*   ガーベージコレクタ
+*   ダイナミックローディング (アーキテクチャによる)
+*   移植性が高い．多くのUnix-like/POSIX互換プラットフォーム上で動くだけでなく，Windows， Mac OS
+    X，BeOSなどの上でも動く cf.
+    http://bugs.ruby-lang.org/projects/ruby-trunk/wiki/SupportedPlatformsJa

+
+## コンパイル・インストール
+
+以下の手順で行ってください．
+
+1.  もし `configure` ファイルが見つからない，もしくは `configure.in` より古いようなら， `autoconf` を実行して
+    新しく `configure` を生成する
+
+2.  `configure` を実行して `Makefile` などを生成する
+
+    環境によってはデフォルトのCコンパイラ用オプションが付きます． `configure` オプションで `optflags=..`
+    `warnflags=..` 等で上書きできます．
+
+3.  (必要ならば)`defines.h` を編集する
+
+    多分，必要無いと思います．
+
+4.  (必要ならば)`ext/Setup` に静的にリンクする拡張モジュールを指定する
+
+    `ext/Setup` に記述したモジュールは静的にリンクされます．
+
+    ダイナミックローディングをサポートしていないアーキテクチャでは `Setup` の1行目の「`option nodynamic`」という行のコ
+    メントを外す必要があります．また，このアーキテクチャで拡張モジュールを利用するためには，あらかじめ静的にリンクをしておく必要があります．
+
+5.  `make` を実行してコンパイルする
+
+6.  `make check`でテストを行う．
+
+    「`check succeeded`」と表示されれば成功です．ただしテストに成功しても完璧だと保証されている訳ではありません．
+
+7.  `make install`
+
+    以下のディレクトリを作って，そこにファイルをインストー ルします．
+
+    *   `${DESTDIR}${prefix}/bin`
+    *   `${DESTDIR}${prefix}/include/ruby-${MAJOR}.${MINOR}.${TEENY}`
+    *   `${DESTDIR}${prefix}/include/ruby-${MAJOR}.${MINOR}.${TEENY}/${PLATFORM}`
+    *   `${DESTDIR}${prefix}/lib`
+    *   `${DESTDIR}${prefix}/lib/ruby`
+    *   `${DESTDIR}${prefix}/lib/ruby/${MAJOR}.${MINOR}.${TEENY}`
+    *   `${DESTDIR}${prefix}/lib/ruby/${MAJOR}.${MINOR}.${TEENY}/${PLATFORM}`
+    *   `${DESTDIR}${prefix}/lib/ruby/site_ruby`
+    *   `${DESTDIR}${prefix}/lib/ruby/site_ruby/${MAJOR}.${MINOR}.${TEENY}`
+    *   `${DESTDIR}${prefix}/lib/ruby/site_ruby/${MAJOR}.${MINOR}.${TEENY}/${PLATFORM}`
+    *   `${DESTDIR}${prefix}/lib/ruby/vendor_ruby`

+    *   `${DESTDIR}${prefix}/share/man/man1`
+    *   `${DESTDIR}${prefix}/share/ri/${MAJOR}.${MINOR}.${TEENY}/system`
+
+
+    RubyのAPIバージョンが'*x.y.z*'であれば，`${MAJOR}`は
+    '*x*'で，`${MINOR}`は'*y*'，`${TEENY}`は'*z*'です．
+
+    **注意**: APIバージョンの `teeny` は，Rubyプログラムのバージョンとは異なることがあります．
+
+    `root` で作業する必要があるかもしれません．
+
+
+もし，コンパイル時にエラーが発生した場合にはエラーのログとマシン，OSの種類を含むできるだけ詳しいレポートを作者に送って下さると他の方のためにもなります．
+
+## 移植
+
+UNIXであれば `configure` がほとんどの差異を吸収してくれるはずですが，思わぬ見落としがあった場合(ある事が多い)，作者にその
+ことを報告すれば，解決できる可能性があります．
+
+アーキテクチャにもっとも依存するのはGC部です．RubyのGCは対象
+のアーキテクチャが`setjmp()`または`getcontext()`によって全てのレジスタを `jmp_buf` や `ucontext_t`
+に格納することと， `jmp_buf` や `ucontext_t` とスタックが32bitアラインメントされていることを仮定
+しています．特に前者が成立しない場合の対応は非常に困難でしょう． 後者の解決は比較的簡単で， `gc.c` でスタックをマークしている
+部分にアラインメントのバイト数だけずらしてマークするコードを追加するだけで済みます．`defined(__mc68000__)`で括られてい

+# What's Ruby
+
+Ruby is the interpreted scripting language for quick and easy object-oriented
+programming.  It has many features to process text files and to do system
+management tasks (as in Perl).  It is simple, straight-forward, and
+extensible.
+
+## Features of Ruby
+
+*   Simple Syntax
+*   **Normal** Object-oriented Features (e.g. class, method calls)
+*   **Advanced** Object-oriented Features (e.g. Mix-in, Singleton-method)
+*   Operator Overloading
+*   Exception Handling
+*   Iterators and Closures
+*   Garbage Collection
+*   Dynamic Loading of Object Files (on some architectures)
+*   Highly Portable (works on many Unix-like/POSIX compatible platforms as
+    well as Windows, Mac OS X, BeOS, etc.) cf.
+    http://bugs.ruby-lang.org/projects/ruby-trunk/wiki/SupportedPlatforms
+

+
+## How to compile and install
+
+This is what you need to do to compile and install Ruby:
+
+1.  If you want to use Microsoft Visual C++ to compile ruby, read
+    win32/README.win32 instead of this document.
+
+2.  If `./configure` does not exist or is older than configure.in, run
+    `autoconf` to (re)generate configure.
+
+3.  Run `./configure`, which will generate `config.h` and `Makefile`.
+
+    Some C compiler flags may be added by default depending on your
+    environment.  Specify `optflags=..` and `warnflags=..` as necessary to
+    override them.
+
+4.  Edit `defines.h` if you need. Usually this step will not be needed.
+
+5.  Remove comment mark(`#`) before the module names from `ext/Setup` (or add
+    module names if not present), if you want to link modules statically.
+
+    If you don't want to compile non static extension modules (probably on
+    architectures which do not allow dynamic loading), remove comment mark
+    from the line "`#option nodynamic`" in `ext/Setup`.
+
+    Usually this step will not be needed.
+
+6.  Run `make`.
+
+7.  Optionally, run '`make check`' to check whether the compiled Ruby
+    interpreter works well. If you see the message "`check succeeded`", your
+    ruby works as it should (hopefully).
+
+8.  Run '`make install`'
+
+    This command will create the following directories and install files into
+    them.
+
+    *   `${DESTDIR}${prefix}/bin`
+    *   `${DESTDIR}${prefix}/include/ruby-${MAJOR}.${MINOR}.${TEENY}`
+    *   `${DESTDIR}${prefix}/include/ruby-${MAJOR}.${MINOR}.${TEENY}/${PLATFORM}`
+    *   `${DESTDIR}${prefix}/lib`
+    *   `${DESTDIR}${prefix}/lib/ruby`
+    *   `${DESTDIR}${prefix}/lib/ruby/${MAJOR}.${MINOR}.${TEENY}`
+    *   `${DESTDIR}${prefix}/lib/ruby/${MAJOR}.${MINOR}.${TEENY}/${PLATFORM}`
+    *   `${DESTDIR}${prefix}/lib/ruby/site_ruby`
+    *   `${DESTDIR}${prefix}/lib/ruby/site_ruby/${MAJOR}.${MINOR}.${TEENY}`
+    *   `${DESTDIR}${prefix}/lib/ruby/site_ruby/${MAJOR}.${MINOR}.${TEENY}/${PLATFORM}`
+    *   `${DESTDIR}${prefix}/lib/ruby/vendor_ruby`
+    *   `${DESTDIR}${prefix}/lib/ruby/vendor_ruby/${MAJOR}.${MINOR}.${TEENY}`
+    *   `${DESTDIR}${prefix}/lib/ruby/vendor_ruby/${MAJOR}.${MINOR}.${TEENY}/${PLATFORM}`
+    *   `${DESTDIR}${prefix}/lib/ruby/gems/${MAJOR}.${MINOR}.${TEENY}`
+    *   `${DESTDIR}${prefix}/share/man/man1`
+    *   `${DESTDIR}${prefix}/share/ri/${MAJOR}.${MINOR}.${TEENY}/system`
+
+
+    If Ruby's API version is '*x.y.z*', the `${MAJOR}` is '*x*', the
+    `${MINOR}` is '*y*', and the `${TEENY}` is '*z*'.
+
+    **NOTE**: teeny of the API version may be different from one of Ruby's
+    program version
+
+    You may have to be a super user to install ruby.
+
+
+If you fail to compile ruby, please send the detailed error report with the
+error log and machine/OS type, to help others.
+
+Some extension libraries may not get compiled because of lack of necessary
+external libraries and/or headers, then you will need to run '`make distclean-ext`'
+to remove old configuration after installing them in such case.

-= How to build ruby using Borland C++
-
-== Requirement
-
-(1) Borland C++ 5.0 or later.
-
-(2) Please set environment variable (({PATH}))
-    to run required commands properly from the command line.
-
-    Note: building ruby requires following commands.
-     * make
-     * bcc32
-     * tlib
-     * ilink32
-
-(3) If you want to build from CVS source, following commands are required.
-     * bison ((<URL:http://gnuwin32.sourceforge.net/packages/bison.htm>))
-     * sed   ((<URL:http://gnuwin32.sourceforge.net/packages/sed.htm>))
-
-(4) We strongly recommend to build ruby on C++Builder, to link following files.
-     * usebormm.lib
-     * memmgr.lib
-
-    RTL's internal memory manager cannot handle large memory block properly,
-    so we should use borlndmm.dll instead.
-     10000.times { "" << "." * 529671; GC.start } # crash
-
-== How to compile and install
-
-(1) Execute bcc32\configure.bat on your build directory.
-     ex. c:\src\ruby> bcc32\configure.bat
-    You can specify the target platform as an argument.
-    For example, run `((%configure i686-bccwin32%))'
-    You can also specify the install directory.
-    For example, run `((%configure --prefix=<install_directory>%))'
-    Default of the install directory is /usr .
-    The default ((|<PLATFORM>|)) is `(({i386-bccwin32}))'.
-     
-(2) Change ((|RUBY_INSTALL_NAME|)) and ((|RUBY_SO_NAME|)) in (({Makefile}))
-    if you want to change the name of the executable files. 
-    And add ((|RUBYW_INSTALL_NAME|)) to change the name of the
-    executable without console window if also you want.
-
-(3) Run `((%make%))'
-
-(4) Run `((%make test%))'
-
-(5) Run `((%make install%))'
-
-(6) Requires dynamic RTL (cc3250.dll on C++Builder5) and borlndmm.dll (If built with
-    usebormm.lib) to use installed binary. These files are ordinary in bcc32's bin
-    directory.
-
-== Icons
-
-Any icon files(*.ico) in the build directory, directories specified with
-((|icondirs|)) make variable and (({win32})) directory under the ruby
-source directory will be included in DLL or executable files, according
-to their base names.
-    $(RUBY_INSTALL_NAME).ico or ruby.ico   --> $(RUBY_INSTALL_NAME).exe
-    $(RUBYW_INSTALL_NAME).ico or rubyw.ico --> $(RUBYW_INSTALL_NAME).exe
-    the others                             --> $(RUBY_SO_NAME).dll
-
-Although no icons are distributed with the ruby source or in the official 
-site, you can use anything you like. For example, followings are written 
-in Japanese, but you can download at least.
-
-* ((<URL:http://member.nifty.ne.jp/ueivu/rubyico.html>)) or
-  ((<zipped icons|URL:http://member.nifty.ne.jp/ueivu/Ruby_ico.zip>))
-* ((<URL:http://homepage1.nifty.com/a_nakata/ruby/>)) or
-  ((<icon itself|URL:http://homepage1.nifty.com/a_nakata/ruby/RubyIcon.ico>))
-
-== Build examples
-
-* Build on the ruby source directory.
-
-  ex.)
-    ruby source directory:  C:\ruby
-    build directory:        C:\ruby
-    install directory:      C:\usr\local
-
-    C:
-    cd \ruby
-    bcc32\configure --prefix=/usr/local
-    make
-    make test
-    make install
-
-* Build on the relative directory from the ruby source directory and CPU type 
-  i386.
-
-  ex.)
-    ruby source directory:  C:\ruby
-    build directory:        C:\ruby\bccwin32
-    install directory:      C:\usr\local
-    CPU                     i386
-    
-    C:
-    cd \ruby
-    mkdir bccwin32
-    cd bccwin32
-    ..\bcc32\configure --prefix=/usr/local
-    make
-    make test
-    make install
-
-* Build on the different drive.
-
-  ex.)
-    ruby source directory:  C:\src\ruby
-    build directory:        D:\build\ruby
-    install directory:      C:\usr\local
-
-    D:
-    cd D:\build\ruby
-    C:\src\ruby\bcc32\configure --prefix=C:/usr/local
-    make
-    make test
-    make install
-
-== Bugs
-
-You can ((*NOT*)) use a path name contains any white space characters as
-the ruby source directory, this restriction comes from the behavior of
-(({!INCLUDE})) directives of (({MAKE})).
-((- you may call it a bug. -))
