+	  2nd, usually Zlib::GzReader.new is not called directly.  #initialize
+	  is called via .open, and in the method the I/O is opened in binary
+	  mode, so there is no problem without changing the mode in #initialize.

+	* class.c, constant.h, gc.c, method.h, object.c, variable.c,

+	  The problem is, you have to connect to the imaps server via
+	  the canonical name written in a server certificate, and that
+	  of the server.cert is "localhost".  So you have to listen to
+	  the address of what "localhost" resolves to.  I think this
+	  situation cannot be resolved in a handy manner because the
+	  test "test_imaps_post_connection_check" is actually
+	  expecting to connect to a server via an address other than
+	  the CN.  On my machine several assertions won't pass because
+	  the test cannot connect to the server.

-		  GNU LESSER GENERAL PUBLIC LICENSE
-		       Version 2.1, February 1999
-
- Copyright (C) 1991, 1999 Free Software Foundation, Inc.
-     59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
-[This is the first released version of the Lesser GPL.  It also counts
- as the successor of the GNU Library Public License, version 2, hence
- the version number 2.1.]
-
-			    Preamble
-
-  The licenses for most software are designed to take away your
-freedom to share and change it.  By contrast, the GNU General Public
-Licenses are intended to guarantee your freedom to share and change
-free software--to make sure the software is free for all its users.
-
-  This license, the Lesser General Public License, applies to some
-specially designated software packages--typically libraries--of the
-Free Software Foundation and other authors who decide to use it.  You
-can use it too, but we suggest you first think carefully about whether
-this license or the ordinary General Public License is the better
-strategy to use in any particular case, based on the explanations below.
-
-  When we speak of free software, we are referring to freedom of use,
-not price.  Our General Public Licenses are designed to make sure that
-you have the freedom to distribute copies of free software (and charge
-for this service if you wish); that you receive source code or can get
-it if you want it; that you can change the software and use pieces of
-it in new free programs; and that you are informed that you can do
-these things.
-
-  To protect your rights, we need to make restrictions that forbid
-distributors to deny you these rights or to ask you to surrender these
-rights.  These restrictions translate to certain responsibilities for
-you if you distribute copies of the library or if you modify it.
-
-  For example, if you distribute copies of the library, whether gratis
-or for a fee, you must give the recipients all the rights that we gave
-you.  You must make sure that they, too, receive or can get the source
-code.  If you link other code with the library, you must provide
-complete object files to the recipients, so that they can relink them
-with the library after making changes to the library and recompiling
-it.  And you must show them these terms so they know their rights.
-
-  We protect your rights with a two-step method: (1) we copyright the
-library, and (2) we offer you this license, which gives you legal
-permission to copy, distribute and/or modify the library.
-
-  To protect each distributor, we want to make it very clear that
-there is no warranty for the free library.  Also, if the library is
-modified by someone else and passed on, the recipients should know
-that what they have is not the original version, so that the original
-author's reputation will not be affected by problems that might be
-introduced by others.
-
-  Finally, software patents pose a constant threat to the existence of
-any free program.  We wish to make sure that a company cannot
-effectively restrict the users of a free program by obtaining a
-restrictive license from a patent holder.  Therefore, we insist that
-any patent license obtained for a version of the library must be
-consistent with the full freedom of use specified in this license.
-
-  Most GNU software, including some libraries, is covered by the
-ordinary GNU General Public License.  This license, the GNU Lesser
-General Public License, applies to certain designated libraries, and
-is quite different from the ordinary General Public License.  We use
-this license for certain libraries in order to permit linking those
-libraries into non-free programs.
-
-  When a program is linked with a library, whether statically or using
-a shared library, the combination of the two is legally speaking a
-combined work, a derivative of the original library.  The ordinary
-General Public License therefore permits such linking only if the
-entire combination fits its criteria of freedom.  The Lesser General
-Public License permits more lax criteria for linking other code with
-the library.
-
-  We call this license the "Lesser" General Public License because it
-does Less to protect the user's freedom than the ordinary General
-Public License.  It also provides other free software developers Less
-of an advantage over competing non-free programs.  These disadvantages
-are the reason we use the ordinary General Public License for many
-libraries.  However, the Lesser license provides advantages in certain
-special circumstances.
-
-  For example, on rare occasions, there may be a special need to
-encourage the widest possible use of a certain library, so that it becomes
-a de-facto standard.  To achieve this, non-free programs must be
-allowed to use the library.  A more frequent case is that a free
-library does the same job as widely used non-free libraries.  In this
-case, there is little to gain by limiting the free library to free
-software only, so we use the Lesser General Public License.
-
-  In other cases, permission to use a particular library in non-free
-programs enables a greater number of people to use a large body of
-free software.  For example, permission to use the GNU C Library in
-non-free programs enables many more people to use the whole GNU
-operating system, as well as its variant, the GNU/Linux operating
-system.
-
-  Although the Lesser General Public License is Less protective of the
-users' freedom, it does ensure that the user of a program that is
-linked with the Library has the freedom and the wherewithal to run
-that program using a modified version of the Library.
-
-  The precise terms and conditions for copying, distribution and
-modification follow.  Pay close attention to the difference between a
-"work based on the library" and a "work that uses the library".  The
-former contains code derived from the library, whereas the latter must
-be combined with the library in order to run.
-
-		  GNU LESSER GENERAL PUBLIC LICENSE
-   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
-
-  0. This License Agreement applies to any software library or other
-program which contains a notice placed by the copyright holder or
-other authorized party saying it may be distributed under the terms of
-this Lesser General Public License (also called "this License").
-Each licensee is addressed as "you".
-
-  A "library" means a collection of software functions and/or data
-prepared so as to be conveniently linked with application programs
-(which use some of those functions and data) to form executables.
-
-  The "Library", below, refers to any such software library or work
-which has been distributed under these terms.  A "work based on the
-Library" means either the Library or any derivative work under
-copyright law: that is to say, a work containing the Library or a
-portion of it, either verbatim or with modifications and/or translated
-straightforwardly into another language.  (Hereinafter, translation is
-included without limitation in the term "modification".)
-
-  "Source code" for a work means the preferred form of the work for
-making modifications to it.  For a library, complete source code means
-all the source code for all modules it contains, plus any associated
-interface definition files, plus the scripts used to control compilation
-and installation of the library.
-
-  Activities other than copying, distribution and modification are not
-covered by this License; they are outside its scope.  The act of
-running a program using the Library is not restricted, and output from
-such a program is covered only if its contents constitute a work based
-on the Library (independent of the use of the Library in a tool for
-writing it).  Whether that is true depends on what the Library does
-and what the program that uses the Library does.
-  
-  1. You may copy and distribute verbatim copies of the Library's
-complete source code as you receive it, in any medium, provided that
-you conspicuously and appropriately publish on each copy an
-appropriate copyright notice and disclaimer of warranty; keep intact
-all the notices that refer to this License and to the absence of any
-warranty; and distribute a copy of this License along with the
-Library.
-
-  You may charge a fee for the physical act of transferring a copy,
-and you may at your option offer warranty protection in exchange for a
-fee.
-
-  2. You may modify your copy or copies of the Library or any portion
-of it, thus forming a work based on the Library, and copy and
-distribute such modifications or work under the terms of Section 1
-above, provided that you also meet all of these conditions:
-
-    a) The modified work must itself be a software library.
-
-    b) You must cause the files modified to carry prominent notices
-    stating that you changed the files and the date of any change.
-
-    c) You must cause the whole of the work to be licensed at no
-    charge to all third parties under the terms of this License.
-
-    d) If a facility in the modified Library refers to a function or a
-    table of data to be supplied by an application program that uses
-    the facility, other than as an argument passed when the facility
-    is invoked, then you must make a good faith effort to ensure that,
-    in the event an application does not supply such function or
-    table, the facility still operates, and performs whatever part of
-    its purpose remains meaningful.
-
-    (For example, a function in a library to compute square roots has
-    a purpose that is entirely well-defined independent of the
-    application.  Therefore, Subsection 2d requires that any
-    application-supplied function or table used by this function must
-    be optional: if the application does not supply it, the square
-    root function must still compute square roots.)
-
-These requirements apply to the modified work as a whole.  If
-identifiable sections of that work are not derived from the Library,
-and can be reasonably considered independent and separate works in
-themselves, then this License, and its terms, do not apply to those
-sections when you distribute them as separate works.  But when you
-distribute the same sections as part of a whole which is a work based
-on the Library, the distribution of the whole must be on the terms of
-this License, whose permissions for other licensees extend to the
-entire whole, and thus to each and every part regardless of who wrote
-it.
-
-Thus, it is not the intent of this section to claim rights or contest
-your rights to work written entirely by you; rather, the intent is to
-exercise the right to control the distribution of derivative or
-collective works based on the Library.
-
-In addition, mere aggregation of another work not based on the Library
-with the Library (or with a work based on the Library) on a volume of
-a storage or distribution medium does not bring the other work under
-the scope of this License.
-
-  3. You may opt to apply the terms of the ordinary GNU General Public
-License instead of this License to a given copy of the Library.  To do
-this, you must alter all the notices that refer to this License, so
-that they refer to the ordinary GNU General Public License, version 2,
-instead of to this License.  (If a newer version than version 2 of the
-ordinary GNU General Public License has appeared, then you can specify
-that version instead if you wish.)  Do not make any other change in
-these notices.
-
-  Once this change is made in a given copy, it is irreversible for
-that copy, so the ordinary GNU General Public License applies to all
-subsequent copies and derivative works made from that copy.
-
-  This option is useful when you wish to copy part of the code of
-the Library into a program that is not a library.
-
-  4. You may copy and distribute the Library (or a portion or
-derivative of it, under Section 2) in object code or executable form
-under the terms of Sections 1 and 2 above provided that you accompany
-it with the complete corresponding machine-readable source code, which
-must be distributed under the terms of Sections 1 and 2 above on a
-medium customarily used for software interchange.
-
-  If distribution of object code is made by offering access to copy
-from a designated place, then offering equivalent access to copy the
-source code from the same place satisfies the requirement to
-distribute the source code, even though third parties are not
-compelled to copy the source along with the object code.
-
-  5. A program that contains no derivative of any portion of the
-Library, but is designed to work with the Library by being compiled or
-linked with it, is called a "work that uses the Library".  Such a
-work, in isolation, is not a derivative work of the Library, and
-therefore falls outside the scope of this License.
-
-  However, linking a "work that uses the Library" with the Library
-creates an executable that is a derivative of the Library (because it
-contains portions of the Library), rather than a "work that uses the
-library".  The executable is therefore covered by this License.
-Section 6 states terms for distribution of such executables.
-
-  When a "work that uses the Library" uses material from a header file
-that is part of the Library, the object code for the work may be a
-derivative work of the Library even though the source code is not.
-Whether this is true is especially significant if the work can be
-linked without the Library, or if the work is itself a library.  The
-threshold for this to be true is not precisely defined by law.
-
-  If such an object file uses only numerical parameters, data
-structure layouts and accessors, and small macros and small inline
-functions (ten lines or less in length), then the use of the object
-file is unrestricted, regardless of whether it is legally a derivative
-work.  (Executables containing this object code plus portions of the
-Library will still fall under Section 6.)
-
-  Otherwise, if the work is a derivative of the Library, you may
-distribute the object code for the work under the terms of Section 6.
-Any executables containing that work also fall under Section 6,
-whether or not they are linked directly with the Library itself.
-
-  6. As an exception to the Sections above, you may also combine or
-link a "work that uses the Library" with the Library to produce a
-work containing portions of the Library, and distribute that work
-under terms of your choice, provided that the terms permit
-modification of the work for the customer's own use and reverse
-engineering for debugging such modifications.
-
-  You must give prominent notice with each copy of the work that the
-Library is used in it and that the Library and its use are covered by
-this License.  You must supply a copy of this License.  If the work
-during execution displays copyright notices, you must include the
-copyright notice for the Library among them, as well as a reference
-directing the user to the copy of this License.  Also, you must do one
-of these things:
-
-    a) Accompany the work with the complete corresponding
-    machine-readable source code for the Library including whatever
-    changes were used in the work (which must be distributed under
-    Sections 1 and 2 above); and, if the work is an executable linked
-    with the Library, with the complete machine-readable "work that
-    uses the Library", as object code and/or source code, so that the
-    user can modify the Library and then relink to produce a modified
-    executable containing the modified Library.  (It is understood
-    that the user who changes the contents of definitions files in the
-    Library will not necessarily be able to recompile the application
-    to use the modified definitions.)
-
-    b) Use a suitable shared library mechanism for linking with the
-    Library.  A suitable mechanism is one that (1) uses at run time a
-    copy of the library already present on the user's computer system,
-    rather than copying library functions into the executable, and (2)
-    will operate properly with a modified version of the library, if
-    the user installs one, as long as the modified version is
-    interface-compatible with the version that the work was made with.
-
-    c) Accompany the work with a written offer, valid for at
-    least three years, to give the same user the materials
-    specified in Subsection 6a, above, for a charge no more
-    than the cost of performing this distribution.
-
-    d) If distribution of the work is made by offering access to copy
-    from a designated place, offer equivalent access to copy the above
-    specified materials from the same place.
-
-    e) Verify that the user has already received a copy of these
-    materials or that you have already sent this user a copy.
-
-  For an executable, the required form of the "work that uses the
-Library" must include any data and utility programs needed for
-reproducing the executable from it.  However, as a special exception,
-the materials to be distributed need not include anything that is
-normally distributed (in either source or binary form) with the major
-components (compiler, kernel, and so on) of the operating system on
-which the executable runs, unless that component itself accompanies
-the executable.
-
-  It may happen that this requirement contradicts the license
-restrictions of other proprietary libraries that do not normally
-accompany the operating system.  Such a contradiction means you cannot
-use both them and the Library together in an executable that you
-distribute.
-
-  7. You may place library facilities that are a work based on the
-Library side-by-side in a single library together with other library
-facilities not covered by this License, and distribute such a combined
-library, provided that the separate distribution of the work based on
-the Library and of the other library facilities is otherwise
-permitted, and provided that you do these two things:
-
-    a) Accompany the combined library with a copy of the same work
-    based on the Library, uncombined with any other library
-    facilities.  This must be distributed under the terms of the
-    Sections above.
-
-    b) Give prominent notice with the combined library of the fact
-    that part of it is a work based on the Library, and explaining
-    where to find the accompanying uncombined form of the same work.
-
-  8. You may not copy, modify, sublicense, link with, or distribute
-the Library except as expressly provided under this License.  Any
-attempt otherwise to copy, modify, sublicense, link with, or
-distribute the Library is void, and will automatically terminate your
-rights under this License.  However, parties who have received copies,
-or rights, from you under this License will not have their licenses
-terminated so long as such parties remain in full compliance.
-
-  9. You are not required to accept this License, since you have not
-signed it.  However, nothing else grants you permission to modify or
-distribute the Library or its derivative works.  These actions are
-prohibited by law if you do not accept this License.  Therefore, by
-modifying or distributing the Library (or any work based on the
-Library), you indicate your acceptance of this License to do so, and
-all its terms and conditions for copying, distributing or modifying
-the Library or works based on it.
-
-  10. Each time you redistribute the Library (or any work based on the
-Library), the recipient automatically receives a license from the
-original licensor to copy, distribute, link with or modify the Library
-subject to these terms and conditions.  You may not impose any further
-restrictions on the recipients' exercise of the rights granted herein.
-You are not responsible for enforcing compliance by third parties with
-this License.
-
-  11. If, as a consequence of a court judgment or allegation of patent
-infringement or for any other reason (not limited to patent issues),
-conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License.  If you cannot
-distribute so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you
-may not distribute the Library at all.  For example, if a patent
-license would not permit royalty-free redistribution of the Library by
-all those who receive copies directly or indirectly through you, then
-the only way you could satisfy both it and this License would be to
-refrain entirely from distribution of the Library.
-
-If any portion of this section is held invalid or unenforceable under any
-particular circumstance, the balance of the section is intended to apply,
-and the section as a whole is intended to apply in other circumstances.
-
-It is not the purpose of this section to induce you to infringe any
-patents or other property right claims or to contest validity of any
-such claims; this section has the sole purpose of protecting the
-integrity of the free software distribution system which is
-implemented by public license practices.  Many people have made
-generous contributions to the wide range of software distributed
-through that system in reliance on consistent application of that
-system; it is up to the author/donor to decide if he or she is willing
-to distribute software through any other system and a licensee cannot
-impose that choice.
-
-This section is intended to make thoroughly clear what is believed to
-be a consequence of the rest of this License.
-
-  12. If the distribution and/or use of the Library is restricted in
-certain countries either by patents or by copyrighted interfaces, the
-original copyright holder who places the Library under this License may add
-an explicit geographical distribution limitation excluding those countries,
-so that distribution is permitted only in or among countries not thus
-excluded.  In such case, this License incorporates the limitation as if
-written in the body of this License.
-
-  13. The Free Software Foundation may publish revised and/or new
-versions of the Lesser General Public License from time to time.
-Such new versions will be similar in spirit to the present version,
-but may differ in detail to address new problems or concerns.
-
-Each version is given a distinguishing version number.  If the Library
-specifies a version number of this License which applies to it and
-"any later version", you have the option of following the terms and
-conditions either of that version or of any later version published by
-the Free Software Foundation.  If the Library does not specify a
-license version number, you may choose any version ever published by
-the Free Software Foundation.
-
-  14. If you wish to incorporate parts of the Library into other free
-programs whose distribution conditions are incompatible with these,
-write to the author to ask for permission.  For software which is
-copyrighted by the Free Software Foundation, write to the Free
-Software Foundation; we sometimes make exceptions for this.  Our
-decision will be guided by the two goals of preserving the free status
-of all derivatives of our free software and of promoting the sharing
-and reuse of software generally.
-
-			    NO WARRANTY
-
-  15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
-WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
-EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
-OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
-KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
-IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
-PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
-LIBRARY IS WITH YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
-THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
-
-  16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
-WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
-AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
-FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
-CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
-LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
-RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
-FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
-SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
-DAMAGES.
-
-		     END OF TERMS AND CONDITIONS
-
-           How to Apply These Terms to Your New Libraries
-
-  If you develop a new library, and you want it to be of the greatest
-possible use to the public, we recommend making it free software that
-everyone can redistribute and change.  You can do so by permitting
-redistribution under these terms (or, alternatively, under the terms of the
-ordinary General Public License).
-
-  To apply these terms, attach the following notices to the library.  It is
-safest to attach them to the start of each source file to most effectively
-convey the exclusion of warranty; and each file should have at least the
-"copyright" line and a pointer to where the full notice is found.
-
-    <one line to give the library's name and a brief idea of what it does.>
-    Copyright (C) <year>  <name of author>
-
-    This library is free software; you can redistribute it and/or
-    modify it under the terms of the GNU Lesser General Public
-    License as published by the Free Software Foundation; either
-    version 2.1 of the License, or (at your option) any later version.
-
-    This library is distributed in the hope that it will be useful,
-    but WITHOUT ANY WARRANTY; without even the implied warranty of
-    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the GNU
-    Lesser General Public License for more details.
-
-    You should have received a copy of the GNU Lesser General Public
-    License along with this library; if not, write to the Free Software
-    Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
-
-Also add information on how to contact you by electronic and paper mail.
-
-You should also get your employer (if you work as a programmer) or your
-school, if any, to sign a "copyright disclaimer" for the library, if
-necessary.  Here is a sample; alter the names:
-
-  Yoyodyne, Inc., hereby disclaims all copyright interest in the

+
+This document is a list of user visible feature changes made between
+releases except for bug fixes.
+
+Note that each entry is kept so brief that no reason behind or
+reference information is supplied with.  For a full list of changes
+with all sufficient information, see the ChangeLog file.
+
+== Changes since the 1.9.2 release
+=== License
+
+* Ruby's License is changed from a dual license with GPLv2
+  to a dual license with 2-clause BSDL.
+
+=== Known platform dependent issues
+==== OS X Lion
+
+* You have to configure ruby with '--with-gcc=gcc-4.2' if you're using
+  Xcode 4.1, or, if you're using Xcode 4.2, you have to configure ruby
+  with '--with-gcc=clang'.
+
+=== C API updates
+
+* rb_scan_args() is enhanced with support for option hash argument
+  extraction.
+
+* ruby_vm_at_exit() added.  This enables extension libs to hook a VM
+  termination.
+
+* rb_reserved_fd_p() added.  If you want to close all file descriptors,
+  check using this API.  [ruby-core:37759]
+
+=== Library updates (outstanding ones only)
+
+* builtin classes
+
+  * ARGF
+    * new methods:
+      * ARGF.print
+      * ARGF.printf
+      * ARGF.putc
+      * ARGF.puts
+      * ARGF.read_nonblock
+      * ARGF.to_write_io
+      * ARGF.write
+
+  * Array
+    * extended method:
+      * Array#pack supports endian modifiers
+
+  * Bignum
+    * Multiplication algorithm for Bignums with a large number of digits over
+      150 BDIGITs is changed in order to reduce its calculation time.
+      Now such large Bignums are multiplied by using Toom-3 algorithm.
+
+  * Encoding
+    * new encodings:
+      * CP950
+      * CP951
+      * UTF-16
+      * UTF-32
+    * change alias:
+      * SJIS is Windows-31J
+
+  * File
+    * new constant:
+      * File::NULL
+        name of NULL device.
+      * File::DIRECT
+        name of O_DIRECT.
+
+  * IO
+    * extended method:
+      * IO#putc supports multibyte characters
+    * new methods:
+      * IO#advise
+      * IO.write(name, string, [offset] )
+        Write `string` to file `name`.
+        Opposite with File.read.
+      * IO.binwrite(name, string, [offset] )
+        binary version of IO.write.
+
+  * Kernel
+    * move #__id__ to BasicObject.
+    * extended method:
+      * Kernel#rand supports range argument
+
+  * Module
+    * new methods:
+      * Module#private_constant
+      * Module#public_constant
+
+  * Random
+    * extended method:
+      * Random.rand supports range argument
+
+  * String
+    * extended method:
+      * String#unpack supports endian modifiers
+    * new method:
+      * String#prepend
+      * String#byteslice
+
+  * Time
+    * extended method:
+      * Time#strftime supports %:z and %::z.
+
+  * Process
+    * Process#maxgroups and Process#maxgroups= now raise NotImplementedError if
+      the platform don't support supplementary groups concept.
+
+* bigdecimal
+
+  * BigDecimal#power and BigDecimal#** support non-integral exponent.
+
+  * Kernel.BigDecimal and BigDecimal.new now accept instances of Integer,
+    Rational, Float, and BigDecimal.  If you pass a Rational or a Float to
+    them, you must specify the precision to produce the digits of a BigDecimal.
+
+  * The behavior of BigDecimal#coerce with a Rational is changed.  It uses
+    the precision of the receiver BigDecimal to produce the digits of a
+    BigDecimal from the given Rational.
+
+* bigdecimal/util
+
+  * BigDecimal#to_d and Integer#to_d are added.
+
+  * Float#to_d accepts a precision.
+
+  * Rational#to_d raises ArgumentError when passing zero or negative
+    precision.
+
+  * Rational#to_d
+
+    * Zero and an implicit precision is deprecated.
+      This feature is removed at the next release of bigdecimal.
+
+    * A negative precision isn't supported.
+      Be careful it is an incompatible change.
+
+* date
+
+  * Accepts flonum explicitly with limitations.
+    * If the given offset is flonum, DateTime assumes its precision is
+      at most second.
+
+      DateTime.new(2001,2,3,0,0,0,3.0/24) ==
+      DateTime.new(2001,2,3,0,0,0,'+03:00')
+        #=> true
+
+    * If the given operand for -/+ is flonum, DateTime assumes its
+      precision is at most nanosecond.
+
+      DateTime.new(2001,2,3) + 0.5 == DateTime.new(2001,2,3,12)
+        #=> true
+
+    * Precision of offset is always at most second.
+
+      Rational('0.5') == Rational('0.500001')  #=> false
+      DateTime.new(2001,2,3,0,0,0,Rational('0.5')) ==
+      DateTime.new(2001,2,3,0,0,0,Rational('0.500001'))
+        #=> true
+
+  * Ignores long offset and far reform day (with warning).
+
+    * Now accepts only:
+
+      -1<=offset<=1 (-24:00..+24:00)
+      2298874<=start<=2426355 or -/+oo
+        (proleptic Gregorian/Julian mean -/+oo)
+
+  * A method strftime cannot produce huge output (same as Time's one).
+
+    * Even though Date/DateTime can handle far dates, the following causes
+      an exception.
+
+      DateTime.new(1<<10000).strftime('%Y')  # Errno::ERANGE
+
+  * Changed the format of inspect.
+  * Changed the format of marshal (but, can load old dumps).
+
+* io/console
+  * new methods:
+    * IO#noecho {|io| }
+    * IO#echo=
+    * IO#echo?
+    * IO#raw {|io| }
+    * IO#raw!
+    * IO#getch
+    * IO#winsize
+    * IO.console
+
+* json
+  * updated to v1.5.4.
+
+* matrix
+  * new classes:
+    * Matrix::EigenvalueDecomposition
+    * Matrix::LUPDecomposition
+  * new methods:
+    * Matrix#diagonal?
+    * Matrix#eigen
+    * Matrix#eigensystem
+    * Matrix#hermitian?
+    * Matrix#lower_triangular?
+    * Matrix#lup
+    * Matrix#lup_decomposition

+    * Matrix#symmetric?
+    * Matrix#unitary?
+    * Matrix#upper_triangular?
+    * Matrix#zero?
+    * Vector#magnitude, #norm
+    * Vector#normalize
+  * extended methods:
+    * Matrix#each and #each_with_index can iterate on a subset of the elements
+    * Matrix#find_index returns [row, column] and can iterate on a subset
+      of the elements
+    * Matrix#** implements Numeric exponents (using the eigensystem)
+    * Matrix.zero can build rectangular matrices
+
+* minitest
+  * Minitest has been updated to version 2.2.2.
+  * For full details, see https://github.com/seattlerb/minitest/blob/master/History.txt

-(3) Please set environment variable (({INCLUDE})), (({LIB})), (({PATH}))
+(2) Please set environment variable (({PATH}))
     to run required commands properly from the command line.
 
     Note: building ruby requires following commands.

      * tlib
-     * ilink

+(4) We strongly recommend to build ruby on C++Builder, to link following files.
+     * usebormm.lib
+     * memmgr.lib
+

 == How to compile and install
 
 (1) Execute bcc32\configure.bat on your build directory.
-     ex. c:\ruby-1.6.7>bcc32\configure.bat
+     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.

+Hello there, Izchak Miller was my father.  When I was younger I spent 
+many a night, hunched over the keyboard with a cup of tea, playing 
+nethack with him and my brother.  my dad was a philosopher with a strong 
+weakness for fantasy/sci fi.  I remember when he started to get involved 
+with the Nethack team- my brother's Dungeons and Dragons monster book 
+found a regular place beside my dad's desk. it's nice to see him living 
+on in the game he loved so much :-).  
+                                                                  Tamar Miller

+ *  Document-class: Fiber
+ *
+ *  Fibers are primitives for implementing light weight cooperative
+ *  concurrency in Ruby. Basically they are a means of creating code blocks
+ *  that can be paused and resumed, much like threads. The main difference
+ *  is that they are never preempted and that the scheduling must be done by
+ *  the programmer and not the VM.
+ *
+ *  As opposed to other stackless light weight concurrency models, each fiber
+ *  comes with a small 4KB stack. This enables the fiber to be paused from deeply
+ *  nested function calls within the fiber block.
+ *
+ *  When a fiber is created it will not run automatically. Rather it must be
+ *  be explicitly asked to run using the <code>Fiber#resume</code> method.
+ *  The code running inside the fiber can give up control by calling
+ *  <code>Fiber.yield</code> in which case it yields control back to caller
+ *  (the caller of the <code>Fiber#resume</code>).
+ *
+ *  Upon yielding or termination the Fiber returns the value of the last
+ *  executed expression
+ *
+ *  For instance:
+ *
+ *    fiber = Fiber.new do
+ *      Fiber.yield 1
+ *      2
+ *    end
+ *
+ *    puts fiber.resume
+ *    puts fiber.resume
+ *    puts fiber.resume
+ *
+ *  <em>produces</em>
+ *
+ *    1
+ *    2
+ *    FiberError: dead fiber called
+ *
+ *  The <code>Fiber#resume</code> method accepts an arbitrary number of
+ *  parameters, if it is the first call to <code>resume</code> then they
+ *  will be passed as block arguments. Otherwise they will be the return
+ *  value of the call to <code>Fiber.yield</code>
+ *
+ *  Example:
+ *
+ *    fiber = Fiber.new do |first|
+ *      second = Fiber.yield first + 2
+ *    end
+ *
+ *    puts fiber.resume 10
+ *    puts fiber.resume 14
+ *    puts fiber.resume 18
+ *
+ *  <em>produces</em>

+ *  Returns the filenames found by expanding <i>pattern</i> which is
+ *  an +Array+ of the patterns or the pattern +String+, either as an
+ *  <i>array</i> or as parameters to the block. Note that this pattern
+ *  is not a regexp (it's closer to a shell glob). See
+ *  <code>File::fnmatch</code> for the meaning of the <i>flags</i>
+ *  parameter. Note that case sensitivity depends on your system (so
+ *  <code>File::FNM_CASEFOLD</code> is ignored), as does the order
+ *  in which the results are returned.
+ *
+ *  <code>*</code>::        Matches any file. Can be restricted by

-* How to compile and install on djgpp
-
-This is what you need to do to compile and install Ruby:
-
-  1. Run configure.bat, which will generate config.h and Makefile
-     (GNU sed required).
-     Message like this is normal:
-       sed.exe: can't read 123456789: No such file or directory (ENOENT)
-
-  2. Edit defines.h if you need.  Probably this step will not need.
-
-  3. Remove comment mark(#) before the module names from ext/Setup.dj (or
-     add module names if not present).
-
-  4. Run make.
-
-  5. Optionally, run 'make test' to check whether the compiled Ruby
-     interpreter works well.  If you see the message "test succeeded",
-     your ruby works as it should (hopefully).
-
-  6. Run 'make install'

+	  However, to traverse living method entries, every control frame push
+	  needs to clear cfp->me field.  This will be a performance issue
+	  (because pushing control frame is occurred frequently).

+	  :widget=>'%W', :keycode=>'%k', '%x'=>:x, '%X'=>:root_x, and so on;
+	  those are attributes of event object). It means that Ruby/Tk accepts
+	  not only "widget.bind(ev, '%W', '%k', ...){|w, k, ...| ... }", but
+	  also "widget.bind(ev, :widget, :keycode, ...){|w, k, ...| ... }".
+	  It is potentially incompatible, when user passes symbols to the
+	  arguments of the callback block (the block receives the symbols as
+	  strings). I think that is very rare case (probably, used by Ruby/Tk
+	  experts only). When causes such trouble, please give strings instead
+	  of such symbol parameters (e.g. call Symbol#to_s method).

+
+	* ext/tk/lib/tkextlib/tile.rb: [incompatible] remove TileWidgets'
+	  instate/state/identify method to avoid the conflict with standard
+	  widget options. Those methods are renamed to ttk_instate/ttk_state/
+	  ttk_identify (tile_instate/tile_state/tile_identify are available
+	  too). Although I don't recommend, if you really need old methods,
+	  please define "Tk::USE_OBSOLETE_TILE_STATE_METHOD = true" before
+	  "require 'tkextlib/tile'".
+
+	* ext/tk/lib/tkextlib/tile.rb: "Tk::Tile::__Import_Tile_Widgets__!"
+	  is obsolete. It outputs warning. To control default widget set,
+	  use "Tk.default_widget_set = :Ttk".
+
+	* ext/tk/lib/tk.rb: __IGNORE_UNKNOWN_CONFIGURE_OPTION__ method and
+	  __set_IGNORE_UNKNOWN_CONFIGURE_OPTION__!(mode) method are defined
+	  as module methods of TkConfigMethod. It may help users to wrap old
+	  Ruby/Tk scripts (use standard widgets) to force to use Ttk widgets.
+	  Ttk widgets don't have some options of standard widgets which are
+	  control the view of widgets. When set ignore-mode true, configure
+	  method tries to ignore such unknown options with no exception.
+	  Of course, it may raise other troubles on the GUI design.
+	  So, those are a little danger methods.
+
+	* ext/tk/lib/tk/itemconfig.rb: __IGNORE_UNKNOWN_CONFIGURE_OPTION__
+	  method and __set_IGNORE_UNKNOWN_CONFIGURE_OPTION__!(mode) method
+	  are defined as module methods of TkItemConfigMethod as the same
+	  purpose as TkConfigMethod's ones.
+
+	* ext/tk/sample/ttk_wrapper.rb: A new example. This is a tool for
+	  wrapping old Ruby/Tk scripts (which use standard widgets) to use
+	  Ttk (Tile) widgets as default.
+
+	* ext/tk/sample/tkextlib/tile/demo.rb: use ttk_instate/ttk_state
+	  method instead of instate/state method.
+
+	* ext/tk/lib/tk/root, ext/tk/lib/tk/namespace.rb,
+	  ext/tk/lib/tk/text.rb, ext/tk/lib/tkextlib/*: some 'instance_eval's
+	  are replaced to "instance_exec(self)".
+
+	* ext/tk/lib/tk/event.rb: bug fix on KEY_TBL and PROC_TBL (?x is not
+	  a character code on Ruby1.9).
+
+	* ext/tk/lib/tk/variable.rb: support new style of operation argument
+	  on Tcl/Tk's 'trace' command for variables.
+
+	* ext/tk/sample/demos-jp/widget, ext/tk/sample/demos-en/widget: bug fix
+
+	* ext/tk/sample/demos-jp/textpeer.rb,

+
+	* ext/tk/tcltklib.c: decrease SEGV troubles (probably)
+
+	* ext/tk/lib/tk.rb: remove Thread.critical access if Ruby1.9
+
+	* ext/tk/lib/tk/multi-tk.rb: support Ruby1.9 (probably)
+
+	* ext/tk/lib/tkextlib/tile.rb: add method to define Tcl/Tk command
+	  to make Tcl/Tk theme sources (based on different version of Tile
+	  extension) available.
+	  (Tk::Tile::__define_LoadImages_proc_for_compatibility__)
+
+	* ext/tk/lib/tk.rb, ext/tk/lib/tk/wm.rb: support dockable frames
+	  (Tcl/Tk8.5 feature). 'wm' command can treat many kinds of widgets
+	  as toplevel widgets.
+
+	* ext/tk/lib/tkextlib/tile/style.rb: ditto.
+	  (Tk::Tile::Style.__define_wrapper_proc_for_compatibility__)
+
+	* ext/tk/lib/tk/font.rb: add actual_hash and metrics_hash to get
+	  properties as a hash. metrics_hash method returns a boolean value
+	  for 'fixed' option. But metrics method returns numeric value
+	  (0 or 1) for 'fixed' option, because of backward compatibility.
+
+	* ext/tk/lib/tk/timer.rb: sometimes fail to set callback procedure.
+
+	* ext/tk/lib/tk.rb: add Tk.sleep and Tk.wakeup method. Tk.sleep
+	  doesn't block the eventloop. It will be better to use the method
+	  in event callbacks.
+
+	* ext/tk/sample/tksleep_sample.rb: sample script about Tk.sleep.

+
+	* ext/tk/lib/tk.rb, ext/tk/lib/*: make default widget set
+	  switchable between Tk (standard Tcl/Tk widget set) and
+	  Ttk (Tile). Initial default widget set is Tk. Now, toplevel
+	  widget classes are removed and defined as aliases.
+	  For example, "TkButton" is an alias of the "Tk::Button" class.
+	  Those aliases are replaced when switching default widget set.
+	  "Tk.default_widget_set=" is the method for switching default
+	  widget set. "Tk.default_widget_set = :Ttk" defines Ttk (Tile)
+	  widget set as default. It means that "TkButton" denotes
+	  "Tk::Tile::Button" class. And then, "TkButton.new" creates
+	  a Tk::Tile::Button widget. Of course, you can back to use
+	  standard Tk widgets as the default widget set by calling
+	  "Tk.default_widget_set = :Tk", whenever you want. Based on
+	  the feature, you can use Ttk widget styling engine on your
+	  old Ruby/Tk application without modifying its source, if you
+	  don't use widget options unsupported on Ttk widgets (At first,
+	  call "Tk.default_widget_set = :Ttk", and next load and run
+	  your application).
+	  This is one step for supporting Tcl/Tk8.5 features.

+	* st.c: uses malloc instead of xmalloc to avoid GC. syck uses st_insert

+
+	* ext/syck/rubyext.c (syck_parser_assign_io): rb_check_string_type can

+	  not syck_free_node, and it won't free data.str->ptr and type_id.
+
+	 (I still think this is unsafe because RString(foo)->ptr becomes

+
+	* lib/{soap,wsdl,xsd}, test/{soap,wsdl,xsd}: imported soap4r/1.5.4.
+
+	  == SOAP client and server ==
+
+	  === for both client side and server side ===
+
+	  * improved document/literal service support.
+	    style(rpc,document)/use(encoding, literal) combination are all
+	    supported.  for the detail about combination, see
+	    test/soap/test_style.rb.
+
+	  * let WSDLEncodedRegistry#soap2obj map SOAP/OM to Ruby according to
+	    WSDL as well as obj2soap.  closes #70.
+
+	  * let SOAP::Mapping::Object handle XML attribute for doc/lit service.
+	    you can set/get XML attribute via accessor methods which as a name
+	    'xmlattr_' prefixed (<foo name="bar"/> -> Foo#xmlattr_name).
+
+	  === client side ===
+
+	  * WSDLDriver capitalized name operation bug fixed.  from
+	    1.5.3-ruby1.8.2, operation which has capitalized name (such as
+	    KeywordSearchRequest in AWS) is defined as a method having
+	    uncapitalized name. (converted with GenSupport.safemethodname
+	    to handle operation name 'foo-bar').  it introduced serious
+	    incompatibility; in the past, it was defined as a capitalized.
+	    define capitalized method as well under that circumstance.
+
+	  * added new factory interface 'WSDLDriverFactory#create_rpc_driver'
+	    to create RPC::Driver, not WSDLDriver (RPC::Driver and WSDLDriver
+	    are merged).  'WSDLDriverFactory#create_driver' still creates
+	    WSDLDriver for compatibility but it warns that the method is
+	    deprecated.  please use create_rpc_driver instead of create_driver.
+
+	  * allow to use an URI object as an endpoint_url even with net/http,
+	    not http-access2.
+
+	  === server side ===
+
+	  * added mod_ruby support to SOAP::CGIStub.  rename a CGI script
+	    server.cgi to server.rb and let mod_ruby's RubyHandler handles the
+	    script.  CGIStub detects if it's running under mod_ruby environment
+	    or not.
+
+	  * added fcgi support to SOAP::CGIStub.  see the sample at
+	    sample/soap/calc/server.fcgi.  (almost same as server.cgi but has
+	    fcgi handler at the bottom.)
+
+	  * allow to return a SOAPFault object to respond customized SOAP fault.
+
+	  * added the interface 'generate_explicit_type' for server side
+	    (CGIStub, HTTPServer).  call 'self.generate_explicit_type = true'
+	    if you want to return simplified XML even if it's rpc/encoded
+	    service.
+
+	  == WSDL ==
+
+	  === WSDL definition ===
+
+	  * improved XML Schema support such as extension, restriction,
+	    simpleType, complexType + simpleContent, ref, length, import,
+	    include.
+
+	  * reduced "unknown element/attribute" warnings (warn only 1 time for
+	    each QName).
+
+	  * importing XSD file at schemaLocation with xsd:import.
+
+	  === code generation from WSDL ===
+
+	  * generator crashed when there's '-' in defined element/attribute
+	    name.
+
+	  * added ApacheMap WSDL definition.
+
+	* sample/{soap,wsdl}: removed.

+	  had become unbuildable; enhanced --enable-fat-binary option so that
+	  it accepts a list of desired architectures (rather than assuming a
+	  fixed list), or defaults to a platform-appropriate list if user does
+	  not provide an explicit list; made the default list of architectures
+	  for MAB (fat binary) more comprehensive; now uses -fno-common even
+	  when building the interpreter (in addition to using it for
+	  extensions), thus allowing the interpreter to be embedded into a
+	  plugin module of an external project (in addition to allowing
+	  embedding directly into an application); added checks for
+	  <netinet/in_systm.h> (needed by `socket' extension) and getcwd(); now
+	  ensures that -I/usr/local/include is employed when extensions'
+	  extconf.rb scripts invoke have_header() since extension checks on
+	  NextStep and OpenStep will fail without it if the desired resource
+	  resides in the /usr/local tree; fixed formatting of --help message.
+
+	* Makefile.in: $(LIBRUBY_A) rule now deletes the archive before
+	  invoking $(AR) since `ar' on Apple/NeXT can not "update" MAB archives
+	  (see configure's --enable-fat-binary option); added rule for new
+	  missing/getcwd.c.
+
+	* defines.h: fixed endian handling during MAB build (see configure's
+	  --enable-fat-binary option) to ensure that all portions of the
+	  project see the correct WORDS_BIGENDIAN value (some extension modules
+	  were getting the wrong endian setting); added missing constants
+	  GETPGRP_VOID, WNOHANG, WUNTRACED, X_OK, and type pid_t for NextStep
+	  and OpenStep; removed unnecessary and problematic HAVE_SYS_WAIT_H
+	  define in NeXT section.
+
+	* dir.c: do not allow NAMLEN() macro to trust dirent::d_namlen on
+	  NextStep since, on some installations, this value always resolves
+	  uselessly to zero.
+
+	* dln.c: added error reporting to NextStep extension loader since the
+	  previous behavior of failing silently was not useful; now ensures
+	  that NSLINKMODULE_OPTION_BINDNOW compatibility constant is defined
+	  for OpenStep and Rhapsody; no longer includes <mach-o/dyld.h> twice
+	  on Rhapsody since this header lacks multiple-include protection,
+	  which resulted in "redefinition" compilation errors.
+
+	* main.c: also create hard reference to objc_msgSend() on NeXT
+	  platforms (in addition to Apple platforms).
+
+	* lib/mkmf.rb: now exports XCFLAGS from configure script to extension
+	  makefiles so that extensions can be built MAB (see configure's
+	  --enable-fat-binary option); also utilize XCFLAGS in cc_command()
+	  (but not cpp_command() because MAB flags are incompatible with
+	  direct invocation of `cpp').
+
+	* ext/curses/extconf.rb: now additionally checks for presence of these
+	  curses functions which are not present on NextStep or Openstep:
+	  bkgd(), bkgdset(), color(), curs(), getbkgd(), init(), scrl(), set(),
+	  setscrreg(), wattroff(), wattron(), wattrset(), wbkgd(), wbkgdset(),
+	  wscrl(), wsetscrreg()
+
+	* ext/curses/curses.c: added appropriate #ifdef's for additional set of
+	  curses functions now checked by extconf.rb; fixed curses_bkgd() and
+	  window_bkgd() to correctly return boolean result rather than numeric
+	  result; fixed window_getbkgd() to correctly signal an error by
+	  returning nil rather than -1.
+
+	* ext/etc/etc.c: setup_passwd() and setup_group() now check for null
+	  pointers before invoking rb_tainted_str_new2() upon fields extracted
+	  from `struct passwd' and `struct group' since null pointers in some
+	  fields are common on NextStep/OpenStep (especially so for the
+	  `pw_comment' field) and rb_tainted_str_new2() throws an exception
+	  when it receives a null pointer.
+
+	* ext/pty/pty.c: include "util.h" for strdup()/ruby_strdup() for
+	  platforms such as NextStep and OpenStep which lack strdup().
+
+	* ext/socket/getaddrinfo.c: cast first argument of getservbyname(),
+	  gethostbyaddr(), and gethostbyname() from (const char*) to non-const
+	  (char*) for older platforms such as NextStep and OpenStep.
+
+	* ext/socket/socket.c: include "util.h" for strdup()/ruby_strdup() for
+	  platforms such as NextStep and OpenStep which lack strdup(); include
+	  <netinet/in_systm.h> if present for NextStep and OpenStep; cast first
+	  argument of gethostbyaddr() and getservbyname() from (const char*) to
+	  non-const (char*) for older platforms.
+
+	* ext/syslog/syslog.c: include "util.h" for strdup()/ruby_strdup() for
+	  platforms such as NextStep and OpenStep which lack strdup().

-  Implemented with fsync(2) or equivalent.
-
-: Dir#pos=
-
-  Returns the new position instead of self.
-
-: Dir::glob

-  Now 1-element array in rhs is expanded properly.
-
-    a = *[1]
-    p a #=> 1
-
-: allocation framework
-
-  any instance of class can be allocated by class.allocate,
-  (except a few classes).
-
-: break and next
-
-  Extended to take an optional expression, which is used as a value
-  for termination. [experimental]
-
-: comparison of exception classes in a rescue clause
-
-  Changed to use Module#=== for comparing $! with the exception
-  class specified in each rescue clause.
-
-  As the previous behavior was to use kind_of?, the effect is limited
-  to the SystemCallError case.  SystemCallError.=== has been newly
-  defined to return true when the two have the same errno.  With this
-  change, SystemCallError's with the same errno, such as Errno::EAGAIN
-  and Errno::EWOULDBLOCK, can both be rescued by listing just one of
-  them.
-
-: constants lookup
-
-  Improved at the performance of searching by using an internal hash
-  table.
-
-: expression parenthesis in the first argument
-
-  Experimentally altered to get the following code (note the space
-  after p):
-
-    p ("xx"*2).to_i
-
-  Interpreted as:
-
-    p (("xx"*2).to_i)
-
-  Instead of:
-
-    (p("xx"*2)).to_i
-
-: implicit comparison in conditional expressions
-
-  Obsoleted except when it is used in -e.
-
-  : between Range and $.
-      Use explicit comparison instead.
-
-  : between Regexp and $_
-      Use the unary method ~/re/ instead.
-
-: to_str
-
-  Added to get objects which define to_str() treated as String's.
-
-  Now almost all the built-in methods try each argument with to_str()
-  when they expect it to be a String.
-
-    foo = Object.new
-    class <<foo
-      def to_str
-        "foo"
-      end
-    end
-    p File.open(foo)
-    => -:7:in `open': wrong argument type Object (expected String) (TypeError)
-       ruby 1.6.4 (2001-04-19) [i586-linux]
-    => -:7:in `open': No such file or directory - "foo" (Errno::ENOENT)
-       ruby 1.7.0 (2001-05-02) [i586-linux]
-

-
-: open
-
-  Extended so that when the third argument is permission flags it
-  calls open(2) instead of fopen(3).

-
-  Added.  If a default value isn't given, raises index error if index
-  is out of range.
-
-: Array#insert(n, other, ...)
-
-  Added. [ruby-talk:14289]
-
-  This is much the same as (({ary[n,0] = [other,...]})) except
-  returing self.
-
-    ary = [0,1,2,3]
-    ary[2, 0] = [4, 5, 6]
-    p ary
-
-    ary = [0,1,2,3]
-    ary.insert(2, 4, 5, 6)
-    p ary
-
-: Array#sort!
-
-  Changed to always return self without checking whether the sequence
-  of the elements was modified or not.
-
-  Beware that this behavior is not guaranteed to continue in the
-  future.  Do not rely on its return value. [ruby-dev:12506]
-
-: Curses
-
-  Updated.  New methods and constants for using the mouse, character
-  attributes, colors and key codes have been added.

-
-  Changed to warn only when invoked from multiple threads or no block
-  is given. [ruby-dev:13823]
-

-        puts Dir.pwd
-      }
-    }

-
-  Localism is FNM_DOTMATCH which has the opposite meaning of the
-  commonly known FNM_PERIOD, which does not exist in Ruby.
-
-  e.g.
-
-    # exclude files matching "*.bak" case-insensitively.
-    files.reject! {|fn| File.fnmatch?("*.bak", fn, File::FNM_CASEFOLD) }
-
-: File.lchmod
-: File.lchown
-
-  Added.
-
-: File.open, IO.open
-
-  File mode can be specified by flags like open(2),
-  e.g. File::open(path, File::CREAT|File::WRONLY).
-
-: IO.open
-
-  Made public.  Can only associate an IO object with a file number
-  like IO.new and IO.for_fd, but can take a block.
-
-: IO.for_fd
-
-  Added as a synonym for IO.new.
-
-: IO.read
-
-  Added.  Like IO.readlines, except it returns the entire file as a
-  string.  [ruby-talk:9460]
-
-: Interrupt
-
-  Made a subclass of SignalException. (It was a subclass of
-  Exception in 1.6 and prior)
-
-: Marshal
-
-  Fixed not to dump anonymous classes/modules.
-
-  Fixed with loading modules.
-
-: MatchData#to_ary
-
-  Added for convenience of Regexp#match. [ruby-dev:12766]
-
-  Previously we had to do:
-
-    foo, bar, baz = /(\w+?)\s+(\w+?)\s+(\w+)/.match("foo bar baz").to_a[1..-1]
-    p [foo, bar, baz]
-
-  But now can do:
-
-    _, foo, bar, baz = /(\w+?)\s+(\w+?)\s+(\w+)/.match("foo bar baz")
-    p [foo, bar, baz]
-
-: Math.acos(x)

-
-  Added.
-
-: Module#include?
-
-  Added. [ruby-dev:13941] 
-
-: Module#included
-
-  Added.  This is a hook called after Module#append_feature.
-
-: Module#method_removed
-: Module#method_undefined
-
-  Added.
-

-  changes. For details, see document embedded in net/http.rb itself.
-
-: NameError and NoMethodError

-: Object#singleton_method_removed
-: Object#singleton_method_undefined
-
-  Added.
-
-: Proc#==
-
-  Added.
-
-: Proc#yield
-
-  Added.  This is equivalent to Proc#call except it does not check the
-  number of given arguments, which are thus passed to the proc as-is.
-
-: Process.times
-
-  Moved from Time.times. (Time.times still remains but emits a
-  warning)
-
-: Process.waitall
-
-  Added.
-
-: Process::Status
-
-  Added.  (({$?})) is now an instance of this class.
-
-: Range#step([step=1])

-  Added.  You can now do something like this:
-
-    a, b, c = 1..3

-
-  Added.  This is a case insensitive version of String#<=>.
-
-: String#chomp
-
-  If $/ == "\n", chops off last newlines (any of \n, \r, \r\n).
-
-: String#eql?
-
-  Changed to be always case sensitive.
-
-: String#insert(n, other)
-
-  Added.
-
-  This is much the same as (({str[n, 0] = other})) except returing
-  self.
-
-: String#lstrip, rstrip, lstrip!, rstrip!
-
-  Added.  These strip only left or right part of a string.

-    => Thu Jan 01 08:59:59 JST 1970
-
-: Time#to_a

+
+This document is a list of user visible feature changes made between
+releases except for bug fixes.
+
+Note that each entry is kept so brief that no reason behind or
+reference information is supplied with.  For a full list of changes
+with all sufficient information, see the ChangeLog file.
+
+== Changes since the 1.8.6 release
+
+=== Configuration changes
+
+* default C flags
+
+  Some C compiler flags may be added by default depending on your
+  environment.  Specify optflags=.. and warnflags=.. as necessary to
+  override them.
+
+* vendor_ruby directory
+
+  A new library directory named `vendor_ruby' is introduced in
+  addition to `site_ruby'.  The idea is to separate libraries
+  installed by the package system (`vendor') from manually (`site')
+  installed libraries preventing the former from getting overwritten
+  by the latter, while preserving the user option to override vendor
+  libraries with site libraries. (`site_ruby' takes precedence over
+  `vendor_ruby')
+
+  If you are a package maintainer, make each library package configure
+  the library passing the `--vendor' option to `extconf.rb' so that
+  the library files will get installed under `vendor_ruby'.
+
+  You can change the directory locations using configure options such
+  as `--with-sitedir=DIR' and `--with-vendordir=DIR'.

+
+=== Interpreter Implementation
+
+* passing a block to a Proc [experimental]
+
+  This implementation in current shape is known to be buggy/broken,
+  especially with nested block invocation.  Take this as an
+  experimental feature.
+
+* stack trace
+
+  On non-SystemStackError exception, full stack trace is shown.
+
+=== Compatibility issues (excluding feature bug fixes)
+
+* String#slice! had some unintentional bugs and they have been fixed
+  because either they disagreed with documentation or their respective
+  behavior of #slice.  Unfortunately, this causes some
+  incompatibilities in the following (somewhat rare) cases.
+
+  * #slice! no longer expands the array when an out-of-boundary value
+    is given.
+
+      # Ruby 1.8.6
+      a = [1,2]
+      a.slice!(4,0)   #=> nil
+      a               #=> [1,2,nil,nil]
+
+      # Ruby 1.8.7
+      a = [1,2]
+      a.slice!(4,0)   #=> nil
+      a               #=> [1,2]
+
+  * #slice! no longer raises an exception but returns nil when a
+    negative length or out-of-boundary negative position is given.
+
+      # Ruby 1.8.6
+      a = [1,2]
+      a.slice!(1,-1)  #=> (raises IndexError)
+      a.slice!(-5,1)  #=> (raises IndexError)
+
+      # Ruby 1.8.7
+      a = [1,2]
+      a.slice!(1,-1)  #=> nil
+      a.slice!(-5,1)  #=> nil
+
+* String#to_i, String#hex and String#oct no longer accept a sequence
+  of underscores (`__') as part of a number.
+
+    # Ruby 1.8.6
+    '1__0'.to_i     #=> 10
+    '1__0'.to_i(2)  #=> 2  # 0b10
+    '1__0'.oct      #=> 8  # 010
+    '1__0'.hex      #=> 16 # 0x10
+
+    # Ruby 1.8.7
+    '1__0'.to_i     #=> 1
+    '1__0'.to_i(2)  #=> 1
+    '1__0'.oct      #=> 1
+    '1__0'.hex      #=> 1
+
+  The old behavior was inconsistent with Ruby syntax and considered as
+  a bug.
+
+* date
+
+  * Date.parse
+
+    '##.##.##' (where each '#' is a digit) is now taken as 'YY.MM.DD'
+    instead of 'MM.DD.YY'.  While the change may confuse you, you can
+    always use Date.strptime() when you know what you are dealing
+    with.
+
+* stringio
+
+  * StringIO#each_byte
+
+    The return value changed from nil to self.  This is what the
+    document says and the same as each_line() does.
+
+* tempfile
+
+  * The file name format has changed.  No dots are included by default
+    in temporary file names any more.  See above for how to specify a
+    suffix.
+
+* uri
+
+  * See above for details.
+
+== Changes since the 1.8.5 release
+
+=== New platforms/build tools support
+
+* IA64 HP-UX
+
+* Visual C++ 8 SP1
+
+* autoconf 2.6x
+
+=== Global constants
+
+* RUBY_PATCHLEVEL
+
+  New constant since 1.8.5-p1.
+
+=== Library updates (outstanding ones only)
+
+* builtin classes
+
+  * New method: Kernel#instance_variable_defined?
+
+  * New method: Module#class_variable_defined?
+
+  * New feature: Dir::glob() can now take an array of glob patterns.
+
+* date
+
+  * Updated based on date2 4.0.3.
+
+* digest
+
+  * New internal APIs for C and Ruby.
+
+  * Support for autoloading.
+
+      require 'digest'
+
+      # autoloads digest/md5
+      md = Digest::MD5.digest("string")
+
+  * New digest class methods: file
+
+  * New digest instance methods: clone, reset, new, inspect,
+    digest_length (alias size or length), block_length()
+
+  * New library: digest/bubblebabble
+
+  * New function: Digest(name)
+
+* fileutils
+
+  * New option for FileUtils.cp_r(): :remove_destination
+
+* nkf
+
+  * Updated based on nkf as of 2007-01-28.
+
+* thread
+
+  * Replaced with much faster mutex implementation in C.  The former
+    implementation, which is slow but considered to be stable, is
+    available with a configure option `--disable-fastthread'.
+
+* tk
+
+  * Updated Tile extension support based on Tile 0.7.8.
+
+  * Support --without-X11 configure option for non-X11 versions of
+    Tcl/Tk (e.g. Tcl/Tk Aqua).
+
+  * New sample script: irbtkw.rbw -- IRB on Ruby/Tk. It has no trouble
+    about STDIN blocking on Windows.
+
+* webrick
+
+  * New method: WEBrick::Cookie.parse_set_cookies()
+
+=== Compatibility issues (excluding feature bug fixes)
+
+* builtin classes
+
+  * String#intern now raises SecurityError when $SAFE level is greater
+    than zero.
+
+* date
+
+  * Time#to_date and Time#to_datetime are added as private methods.
+    They cause name conflict error in ActiveSupport 1.4.1 and prior,
+    which comes with Rails 1.2.2 and prior.  Updating ActiveSupport
+    and/or Rails to the latest versions fixes the problem.
+
+* digest
+
+  * The constructor does no longer take an initial string to feed.
+    The following examples show how to migrate:
+
+      # Before
+      md = Digest::MD5.new("string")
+      # After (works with any version)
+      md = Digest::MD5.new.update("string")
+        
+      # Before
+      hd = Digest::MD5.new("string").hexdigest
+      # After (works with any version)
+      hd = Digest::MD5.hexdigest("string")
+
+  * Digest::Base#==
+
+    * self == string
+
+      Automatic detection between binary digest values and hexadecimal
+      digest values has been dropped.  It is always assumed that a
+      hexadecimal digest value is given for comparison.
+
+    * self == md
+
+      Digest objects are compared by the resulting digest values, not
+      by the exact vector states.
+
+* fileutils
+
+  * A minor implementation change breaks Rake <=0.7.1.
+    Updating Rake to 0.7.2 or higher fixes the problem.
+
+* tk
+
+  * Tk::X_Scrollable (Y_Scrollable) is renamed to Tk::XScrollable
+    (YScrollable). Tk::X_Scrollable (Y_Scrollable) is still available,
+    but it is an alias name.

+
+== Changes since the 1.8.7 release
+See doc/NEWS-1.8.7 for changes between 1.8.6 and 1.8.7.
+
+=== Compatibility issues
+
+* language core
+
+    * New syntax and semantics
+          o Block arguments are always local
+          o New semantics for block arguments
+          o defined? and local variables
+          o Parser expects that your source code has only valid byte
+            sequence in some character encoding.  Use magic comments
+            to tell the parser which encoding you use.
+          o New semantics for constant definition in instance_eval
+            or in module_eval.
+
+    * Deprecated syntax
+          o colon (:) instead of "then" in if/unless or case expression.
+          o retry in a loop or an iterator.
+
+* builtin classes and objects
+
+    * Kernel and Object
+          o Kernel#methods and #singleton_methods used to return an 
+            array of strings but now they return an array of symbols.
+    * Class and Module
+          o Module#attr works as Module#attr_reader by default.
+	    Optional boolean argument is obsolete.
+          o Module#instance_methods, #private_instance_methods and
+            #public_instance_methods used to return an array of 
+            strings but now they return an array of symbols.
+          o Extra subclassing check when binding UnboundMethods
+            
+    * Exceptions
+          o Exceptions are equal to each other if they belong to 
+            the same class and have the same message and backtrace.
+          o SystemStackError used to be a subclass of StandardError
+            but not it is a direct subclass of Exception.
+          o SecurityError: ditto
+          o Removed Exception#to_str [Ruby2]
+
+    * Enumerable and Enumerator
+          o Enumerable::Enumerator, compatibility alias of Enumerator,
+            is removed.
+          o Enumerable#{map,collect} called without a block returns
+            an enumerator.
+          o Even more builtin and bundled libraries have been made to
+            return an enumerator when called without a block.
+    * Array
+          o Array#nitems was removed (use count {|i| !i.nil?})
+          o Array#choice was removed (use sample)
+          o Array#[m,n] = nil places nil in the array.
+    * Hash
+          o Hash#to_s is equivalent to Hash#inspect
+          o Semantics for Hash#each and Hash#each_pair
+          o Hash#select returns a hash
+          o Hash#key is the new name for #index which has been
+            deprecated.
+          o Hash preserves order.  It enumerates its elements in the
+            order in which the keys are inserted.
+          o Most of the changes in Hash apply to hash like interfaces
+            such as ENV and *DBM.
+    * IO operations
+          o Many methods used to act byte-wise but now some of those act 
+            character-wise. You can use alternate byte-wise methods.
+          o IO#getc
+          o Non-blocking IO
+          o Kernel#open takes "t" for newline conversion
+          o Kernel#open takes encoding specified
+          o IO automatically converts byte sequence from a character
+            encodings into another if specified.
+          o StringIO#readpartial
+          o IO.try_convert
+          o IO.binread
+          o IO.copy_stream
+          o IO#binmode?
+          o IO#close_on_exec= and IO#close_on_exec?
+          o Limit input in IO#gets, IO#readline, IO#readlines,
+            IO#each_line, IO#lines, IO.foreach, IO.readlines,
+            StringIO#gets, StringIO#readline, StringIO#each,
+            StringIO#readlines
+          o IO#ungetc, StringIO#ungetc
+          o IO#ungetbyte, StringIO#ungetbyte
+          o IO#internal_encoding, IO#external_encoding,
+            IO#set_encoding
+          o IO.pipe takes encoding option
+          o Directive %u behaves like %d for negative values in 
+            printf-style formatting.
+    * File and Dir operations
+          o #to_path is called as necessary in File.path, File.chmod,
+            File.lchmod, File.chown, File.lchown, File.utime,
+            File.unlink, etc..
+          o File.world_readable?
+          o File.world_writable?
+          o Dir.[], Dir.glob
+          o Dir.exist?
+          o Dir.exists?
+    * File::Stat
+          o File::Stat#world_readable?
+          o File::Stat#world_writable?
+    * String
+          o No longer an Enumerable: use each_line/lines for line
+            oriented operation
+          o Encoding-awareness
+              o Character-wise semantics in many methods instead of
+                byte-wise.
+                  o String#[]: Indexing a String with an integer returns a
+                    single character String instead of an integer.
+                  o String#[]=: No longer takes an integer as right
+                    side value.  Note that "str[i] = ?c" because of
+                    the following change.
+                  o ?c is evaluated to a single character string
+                    instead of an integer.
+    * Regexp
+          o Encoding-awareness
+          o Regexp matches only with strings which is encoded in a
+            compatible character encoding to the regexp's.
+          o Regexp#kcode is removed. use Regexp#encoding.
+    * Symbols: restriction on literal symbols
+    * Numeric
+          o Numeric#div always rounds as Integer#div has done.
+          o Numeric#fdiv: ditto.
+    * Integer
+          o Integer(nil) raises TypeError
+    * Fixnum
+          o Fixnum#id2name removed
+          o Fixnum#to_sym removed
+    * Struct
+          o Struct#inspect
+    * Time
+          o New format in Time#to_s
+          o Timezone information preserved on Marshal.dump/load
+    * $SAFE and bound methods
+          o New trusted/untrusted model in addition to
+            tainted/untainted model.
+
+    * Deprecation
+          o $= (global flag for case-sensitiveness on string matching)
+          o Kernel#to_a
+          o Kernel#getc, #gsub, #sub
+          o Kernel#callcc and Continuation now become 'continuation'
+            bundled library.
+          o Object#type
+          o Removed Array and Hash #indices, #indexes
+          o Hash#index
+          o ENV.index
+          o Process::Status#to_int
+          o Numeric#rdiv
+          o Precision is removed.  Don't cry, it will be redesigned
+            and come back in future version.
+          o Symbol#to_int and Symbol#to_i
+          o $KCODE is no longer effective.  Use Encoding related
+            features of each class.
+          o VERSION and friends
+
+* bundled libraries
+
+    * Pathname
+          o No longer has #to_str nor #=~.
+    * time and date
+          o Time.parse and Date.parse interprets slashed numerical dates 
+	    as "dd/mm/yyyy".
+    * Readline
+          o If Readline uses libedit, Readline::HISTORY[0] returns the
+            first of the history.
+    * Continuation
+          o as above
+
+    * Deprecation
+          o Complex#image: use Complex#imag
+          o All SSL-related class methods in Net::SMTP
+          o Prime#cache, Prime#primes, Prime#primes_so_far
+          o mailread library: use tmail gem.
+          o cgi-lib library: use cgi.
+          o date2 library: use date.
+          o eregex library
+          o finalize library: use ObjectSpace.define_finalizer if you
+            really need a finalizer. really?
+          o ftools library: use fileutils.
+          o generator library: use Enumerator.
+          o importenv library and Env library
+          o jcode library: use multilingualization support of String
+          o parsedate library
+          o ping library
+          o readbytes library
+          o getopts library and parsearg library: use optparse or
+            getoptlong.
+          o soap, wsdl and xsd libraries: use soap4r gem.
+          o Win32API library: use dl.
+          o dl library: Reimplemented and API changed. use the new
+	    version of dl or ffi gem.
+          o rubyunit library and runit library: use minitest or
+            test/unit. Or use anything you love through RubyGems.
+          o test/unit is reimplemented on top of minitest.  This is
+            not fully compatible with the original.
+
+=== Language core changes
+
+    * New syntax and semantics
+          o Magic comments to declare in which encoding your source
+            code is written
+          o New literal hash syntax and new syntax for hash style 
+	    arguments

+          o Block local variables
+          o Mandatory arguments after optional arguments allowed
+          o Multiple splats allowed
+          o #[] can take splatted arguments, hash style arguments 
+            and a block.
+          o New directives in printf-style formatted strings (%).
+          o Newlines allowed before ternary colon operator (:) and
+            method call dot operator (.)
+          o Negative operators such as !, != and !~ are now
+            overloadable
+          o Encoding.default_external and default_internal
+          o __ENCODING__: New pseudo variable to hold the current
+            script's encoding
+
+=== Library updates
+
+* builtin classes and objects
+    * Kernel and Object
+          o BasicObject
+          o Object#=~ returns nil instead of false by default.
+          o Kernel#define_singleton_method
+	  o Kernel#load can load a library from the highest versions
+	    of gems by default.
+    * Class and Module
+          o Module#const_defined?, #const_get and #method_defined?
+            take an optional parameter.
+          o #class_variable_{set,get} are public.
+          o Class of singleton classes
+
+    * Errno::EXXX
+          o All of those are always defined.  Errno::EXXX will be
+            defined as an alias to Errno::NOERROR if your platform
+            does not have one.
+
+    * Binding#eval
+    * Blocks and Procs
+          o Arity of blocks without arguments
+          o proc is now a synonym of Proc.new
+          o Proc#yield
+          o Passing blocks to #[]
+          o Proc#lambda?
+          o Proc#curry
+    * Fiber: coroutines/micro-threads
+    * Thread
+          o Thread.critical and Thread.critical= removed
+          o Thread#exit!, Thread#kill! and Thread#terminate! removed.
+
+    * Enumerable and Enumerator
+          o Enumerator#enum_cons and Enumerator#enum_slice are
+            removed.  Use #each_cons and #each_slice without a block.            
+          o Enumerable#each_with_index can take optional arguments
+            and passes them to #each.
+          o Enumerable#each_with_object
+          o Enumerator#with_object
+          o Enumerator.new { ... }
+    * Array
+          o Array#delete returns a deleted element rather than a given
+            object
+          o Array#to_s is equivalent to Array#inspect
+          o Array.try_convert
+          o Array#pack('m0') complies with RFC 4648.
+    * Hash
+          o preserving item insertion order
+          o Hash#default_proc=
+          o Hash#_compare_by_identity and Hash#compare_by_identity?
+          o Hash.try_convert
+          o Hash#assoc
+          o Hash#rassoc

+== Module Function
+
+--- getlogin
+
+	returns login name of the user.  It this fails, try getpwuid().
+
+--- getpwnam(name)
+
+	searches in /etc/passwd file (or equivalent database), and
+	returns password entry for the user.  The return value is an
+	passwd structure, which has members described below.

+pty extension version 0.3 by A.ito
+
+1. Introduction
+
+This extension module adds ruby a functionality to execute an 
+arbitrary command through pseudo tty (pty).
+
+2. Install
+
+Follow the instruction below.
+
+(1) Execute
+
+      ruby extconf.rb
+
+    then Makefile is generated.
+
+(3) Do make; make install.
+
+3. What you can do
+
+This extension module defines a module named PTY, which contains
+following module fungtions:
+
+   getpty(command)
+   spawn(command)
+
+      This function reserves a pty, executes command over the pty 
+      and returns an array. The return value is an array with three
+      elements. The first element in the array is for reading and the 
+      second for writing. The third element is the process ID of the
+      child process. If this function is called with an iterator block,
+      the array is passed to the block as block parameters, and the
+      function itself returns nil.
+
+      When the child process is suspended or finished, an exception is
+      raised.  If this function is called with an iterator block,
+      exception is raised only within the block.  Child process
+      monitor is terminated on block exit.
+
+   protect_signal
+   reset_signal
+
+      These functions are obsolete in this version of pty.
+
+   PTY.open
+
+      Allocates a pty (pseudo-terminal).
+
+      It returns an array which contains an IO object and a File object.
+      The former is the master of the pty.
+      The latter is the slave of the pty.
+
+      If a block is given, it yields the array instead of return.
+      The value of the block is returned.
+      master_io and slave_file is closed when return if they are not closed.
+
+   PTY.check(pid[, raise=false])
+
+      checks the status of the child process specified by pid, and
+      returns nil if the process is still alive and active.
+      Otherwise, returns Process::Status about the process if raise is
+      false, or PTY::ChildExited exception is raised.

+= Rake Changelog
+
+== Version 0.8.7
+
+* Fixed EXEEXT for JRuby on windows.
+
+== Version 0.8.6
+
+* Minor fixes to the RDoc generation (removed dependency on darkfish
+  and removed inline source option).
+
+== Version 0.8.5
+
+* Better support for the system command on Windows.
+
+== Version 0.8.4
+
+* Preserve case when locating rakefiles (patch from James
+  M. Lawrence/quix)
+
+* Better support for windows paths in the test task (patch from Simon
+  Chiang/bahuvrihi)
+
+* Windows system dir search order is now: HOME, HOMEDRIVE + HOMEPATH,
+  APPDATA, USERPROFILE (patch from Luis Lavena)
+
+* MingGW is now recognized as a windows platform.  (patch from Luis
+  Lavena)
+
+* Numerous fixes to the windows test suite (patch from Luis Lavena).
+
+* Improved Rakefile case insensitivity testing (patch from Luis
+  Lavena).
+
+* Fixed stray ARGV option problem that was interfering with
+  Test::Unit::Runner.
+
+* Fixed default verbose mode (was accidently changed to false).  
+
+* Removed reference to manage_gem to fix the warning produced by the
+  gem package task.
+
+== Version 0.8.3
+
+* Enhanced the system directory detection in windows. We now check
+  HOMEDRIVE/HOMEPATH and USERPROFILE if APPDATA isn't found. (Patch
+  supplied by James Tucker). Rake no long aborts if it can't find the
+  directory.
+
+* Added fix to handle ruby installations in directories with spaces in
+  their name.  
+
+== Version 0.8.2
+
+* Fixed bug in package task so that it will include the subdir
+  directory in the package for testing. (Bug found by Adam Majer)
+
+* Added ENV var to rakefile to prevent OS X from including extended
+  attribute junk in a tar file. (Bug found by Adam Majer)
+
+* Fixed filename dependency order bug in test_inspect_pending and
+  test_to_s_pending. (Bug found by Adam Majer)
+
+* Fixed check for file utils options to make them immune to the
+  symbol/string differences. (Patch supplied by Edwin Pratomo)
+
+* Fixed bug with rules involving multiple source (Patch supplied by
+  Emanuel Inderm�hle)
+
+* Switched from getoptlong to optparse (patches supplied by Edwin
+  Pratomo)
+
+* The -T option will now attempt to dynamically sense the size of the
+  terminal.  RAKE_COLUMNS will override any dynamic sensing.
+
+* FileList#clone and FileList#dup have better sematics w.r.t. taint
+  and freeze.
+
+* Added ability clear prerequisites, and/or actions from an existing
+  task.
+
+* Added the ability to reenable a task to be invoked a second time.
+
+* Changed RDoc test task to have no default template. This makes it
+  easier for the tempate to pick up the template from the environment.
+
+* Changed from using Mutex to Monitor. Evidently Mutex causes thread
+  join errors when Ruby is compiled with -disable-pthreads. (Patch
+  supplied by Ittay Dror) 
+
+* Fixed bug in makefile parser that had problems with extra spaces in
+  file task names. (Patch supplied by Ittay Dror)
+
+* Added a performance patch for reading large makefile dependency
+  files. (Patch supplied by Ittay Dror)
+
+* Default values for task arguments can easily be specified with the
+  :with_defaults method. (Idea for default argument merging supplied
+  by (Adam Q. Salter)
+
+* The -T output will only self-truncate if the output is a tty.
+  However, if RAKE_COLUMNS is explicitly set, it will be honored in
+  any case. (Patch provided by Gavin Stark).
+
+* Numerous fixes for running under windows. A big thanks to Bheeshmar
+  Redheendran for spending a good part of the afternoon at the
+  Lonestar Ruby Conference to help me work out these issues.
+
+== Version 0.8.1
+
+* Removed requires on parsedate.rb (in Ftptools)
+* Removed ftools from rake.rb.  Made it options in sys.rb
+
+== Version 0.8.0
+
+* Added task parameters (e.g. "rake build[version7]")
+* Made task parameters passable to prerequisites.
+* Comments are limited to 80 columns or so (suggested by Jamis Buck).
+* Added -D to display full comments (suggested by Jamis Buck).
+* The rake program will set the status value used in any explicit
+  exit(n) calls. (patch provided by Stephen Touset)
+* Fixed error in functional tests that were not including session (and
+  silently skipping the functionl tests.
+* Removed --usage and make -h the same as -H.
+* Make a prettier inspect for tasks.
+
+== Version 0.7.3
+
+* Added existing and existing! methods to FileList
+* FileLists now claim to be Arrays (via is_a?) to get better support
+  from the FileUtil module.
+* Added init and top_level for custom rake applications.
+
+== Version 0.7.2
+
+* Error messages are now send to stderr rather than stdout (from
+  Payton Quackenbush).
+* Better error handling on invalid command line arguments (from Payton
+  Quackenbush).
+* Added rcov task and updated unit testing for better code coverage.
+* Fixed some bugs where the application object was going to the global
+  appliation instead of using its own data.
+* Added square and curly bracket patterns to FileList#include (Tilman
+  Sauerbeck). 
+* Added plain filename support to rule dependents (suggested by Nobu
+  Nakada). 
+* Added pathmap support to rule dependents.
+* Added a 'tasks' method to a namespace to get a list of tasks
+  associated with the namespace.
+* Fixed the method name leak from FileUtils (bug found by Glenn
+  Vanderburg). 
+* Added rake_extension to handle detection of extension collisions.
+* Added test for noop, bad_option and verbose flags to sh command.
+* Removed dependency on internal fu_xxx functions from FileUtils.
+* Added a 'shame' task to the Rakefile.

+  unbreak cruisecontrol.rb.
+* Added the handful of RakeFileUtils to the private method as well.
+* Added block based exclusion.
+* The clean task will no longer delete 'core' if it is a directory.
+* Removed rake_dup.  Now we just simply rescue a bad dup.
+* Refactored the FileList reject logic to remove duplication.
+* Removed if __FILE__ at the end of the rake.rb file.
+
+== Version 0.7.1
+
+* Added optional filter parameter to the --tasks command line option.
+* Added flatten to allow rule transform procs to return lists of
+  prereqs (Joel VanderWerf provided patch).
+* Added pathmap to String and FileList.

+  doesn't yet).  NOTE: This is experimental ... it may be
+  discontinued.
+* The -f option without a value will disable the search for a
+  Rakefile.  The assumption is that the -r files are adequate.
+* Fixed the safe_ln function to fall back to cp in more error
+  scenarios.

+  supplied test case).
+* Made the RDoc task default to internal (in-process) RDoc formatting.
+  The old behavior is still available by setting the +external+ flag
+  to true.
+* Rakefiles are now loaded with the expanded path to prevent
+  accidental polution from the Ruby load path.
+* The +namespace+ command now returns a NameSpace object that can be
+  used to lookup tasks defined in that namespace.  This allows for
+  better anonymous namespace behavior.
+* Task objects my now be used in prerequisite lists directly.
+
+== Version 0.6.1
+
+* Rebuilt 0.6.0 gem without signing.
+
+== Version 0.6.0
+
+* Fixed file creation bug in the unit tests (caused infinite loop on
+  windows).
+* Fixed bug where session based functional tests were run under
+  windows.
+* Fixed bug in directory tasks so that updating a directory will not
+  retrigger file tasks depending on the directory (see
+  FileCreationTask and EarlyTime).
+* Added egrep to FileList
+* ruby command now runs same ruby version as rake.
+* Added investigation to task object. (suggested by Martin Fowler)
+* Added ruby_opts to the test task to allow arbitrary ruby options to
+  be passed to the test script. (Greg Fast)
+* Fixed the test loader to ignore options. (Greg Fast)
+* Moved Task, FileTask, FileCreationTask and RakeApp into the Rake
+  module namespace.  Old style namespace behavior can be invoked via
+  the --classic-namespace option. (requested by Kelly Felkins).
+* GemTask is now sensitive to the gem platform (Masao Mutoh).
+* A non-existing file prerequisite will no longer cause an exception
+  (Philipp Neubeck).
+* Multiple prerequisites on Rake rules now allowed (initial patch
+  supplied by Stuart Jansen).
+
+== Version 0.5.4
+
+* Added double quotes to the test runner.
+* Added .svn to default ignore list.
+* Updated FileList#include to support nested arrays and filelists.
+
+== Version 0.5.3
+
+* Added support for importing Rakefile and other dependencies.
+* Fixed bug so that now rules can chain off of existing tasks as well
+  as existing files.
+* Fixed verbose flag bug in the testing task.  Shortened some failure
+  messages.
+* Make FileUtils methods private at the top level module to avoid
+  accidental method leaking into other objects.
+* Added test loader option to test task.  "testrb" is no longer the
+  default test loader.  It is now eating syntax errors that should
+  halt the unit tests.
+* Revamped FileList so that it works more like and array (addressed
+  flatten bug).  Added many tests around file list.
+* Added +ext+ method to both String and FileList.
+
+== Version 0.5.0
+
+* Fixed documentation that was lacking the Rake module name (Tilman
+  Sauerbeck).
+* Added tar.gz and tar.bz2 support to package task (Tilman Sauerbeck).
+* Recursive rules are now supported (Tilman Sauerbeck).

+* Added Brian Candler's fix for problems in --trace and --dry-run
+  mode.
+
+== Version 0.4.15
+
+* Fixed a bug that prevented the TESTOPTS flag from working with the
+  revised for 1.8.2 test task.
+* Updated the docs on --trace to indicate that it also enables a full
+  backtrace on errors. 
+
+== Version 0.4.14
+
+* Modified the TestTask to workaround the Ruby 1.8.2 change in
+  autoexecuting unit tests.
+
+== Version 0.4.13
+
+* Fixed the dry-run flag so it is operating again.
+* Multiple arguments to sh and ruby commands will not be interpreted
+  by the shell (patch provided by Jonathan Paisley).

+
+* Added --silent (-s) to suppress the (in directory) rake message.
+
+== Version 0.4.11
+
+* Changed the "don't know how to rake" message (finally)
+* Changes references to a literal "Rakefile" to reference the global
+  variable $rakefile (which contains the actual name of the rakefile).
+
+== Version 0.4.10
+
+* Added block support to the "sh" command, allowing users to take
+  special actions on the result of the system call.  E.g.
+
+    sh "shell_command" do |ok, res|
+      puts "Program returned #{res.exitstatus}" if ! ok
+    end
+
+== Version 0.4.9

+  added back into the list of methods to rewrite in FileList.  (Thanks
+  to Kent Sibilev for pointing this out).
+
+== Version 0.4.6
+* Removed test version of ln in FileUtils that prevented safe_ln from
+  using ln.
+
+== Version 0.4.5
+* Upgraded comments in TestTask.
+* FileList to_s and inspect now automatically resolve pending changes.

+  macros.
+* Allow a +test_files+ attribute in test tasks.  This allows more
+  flexibility in specifying test files.
+

+= RAKE -- Ruby Make 
+
+Supporting Rake version: 0.8.6
+
+This package contains Rake, a simple ruby build program with
+capabilities similar to make.
+
+Rake has the following features:
+
+* Rakefiles (rake's version of Makefiles) are completely defined in
+  standard Ruby syntax.  No XML files to edit.  No quirky Makefile
+  syntax to worry about (is that a tab or a space?)
+
+* Users can specify tasks with prerequisites.
+
+* Rake supports rule patterns to synthesize implicit tasks.
+
+* Flexible FileLists that act like arrays but know about manipulating
+  file names and paths.
+
+* A library of prepackaged tasks to make building rakefiles easier. For example,
+  tasks for building tarballs, gems and RDoc output are provided.
+
+* Supports parallel execution of tasks.
+
+
+== Installation
+
+=== Gem Installation
+
+Download and install  rake with the following.
+
+   gem install rake
+
+=== Normal Installation
+
+You can download the source tarball of the latest version of Rake from
+
+* http://rubyforge.org/project/showfiles.php?group_id=50
+
+Extract the tarball and run
+
+  % ruby install.rb
+
+from its distribution directory.
+
+== Usage
+
+=== Simple Example
+
+First, you must write a "Rakefile" file which contains the build rules. Here's
+a simple example:
+
+  task :default => [:test]
+  
+  task :test do
+    ruby "test/unittest.rb"
+  end
+
+This Rakefile has two tasks:
+
+* A task named "test", which - upon invocation - will run a unit test file in
+  Ruby.
+* A task named "default". This task does nothing by itself, but it has exactly
+  one dependency, namely the "test" task. Invoking the "default" task will
+  cause Rake to invoke the "test" task as well.
+
+Running the "rake" command without any options will cause it to run the
+"default" task in the Rakefile:
+
+  % ls
+  Rakefile     test/
+  % rake
+  (in /home/some_user/Projects/rake)
+  ruby test/unittest.rb
+  ....unit test output here...
+
+Type "rake --help" for all available options.
+
+
+=== More Information
+
+* For details on Rake's command-line invocation, read
+  doc/command_line_usage.rdoc[http://rake.rubyforge.org/files/doc/command_line_usage_rdoc.html]
+* For details on writing Rakefiles, see
+  doc/rakefile.rdoc[http://rake.rubyforge.org/files/doc/rakefile_rdoc.html].
+* For the original announcement of Rake, see
+  doc/rational.rdoc[http://rake.rubyforge.org/files/doc/rational_rdoc.html].
+* For a glossary of terms, see
+  doc/glossary.rdoc[http://rake.rubyforge.org/files/doc/glossary_rdoc.html].
+
+
+== Development
+
+=== Source Repository
+
+Rake is currently hosted at github. The github web page is
+http://github.com/jimweirich/rake. The public git clone URL is
+
+* git://github.com/jimweirich/rake.git
+
+=== Running the Rake Test Suite
+
+If you wish to run the unit and functional tests that come with Rake:
+
+* Install the 'session' gem in order to run the functional tests.
+* CD into the top project directory of rake.
+* Type one of the following:
+
+     rake                  # If you have a version of rake installed
+     ruby -Ilib bin/rake   # If you do not have a version of rake installed.

+= Rake Command Line Usage
+
+Rake is invoked from the command line using:
+
+   % rake [<em>options</em> ...]  [<em>VAR</em>=<em>VALUE</em>]  [<em>targets</em> ...]
+
+Options are:
+
+[<tt><em>name</em>=<em>value</em></tt>]
+    Set the environment variable <em>name</em> to <em>value</em>
+    during the execution of the <b>rake</b> command.  You can access
+    the value by using ENV['<em>name</em>'].  
+
+[<tt>--classic-namespace</tt> (-n)]
+    Import the Task, FileTask, and FileCreateTask into the top-level
+    scope to be compatible with older versions of Rake.  Alternatively
+    you can include the line <code>require
+    'rake/classic_namespace'</code> in your Rakefile to get the
+    classic behavior.
+
+[<tt>--describe</tt> _pattern_ (-D)]
+    Describe the tasks (matching optional PATTERN), then exit.
+
+[<tt>--dry-run</tt> (-n)]
+    Do a dry run.  Print the tasks invoked and executed, but do not
+    actually execute any of the actions.
+
+[<tt>--execute</tt> _code_ (-e)]
+    Execute some Ruby code and exit.
+
+[<tt>--execute-print</tt> _code_ (-p)]
+    Execute some Ruby code, print the result, and exit.
+
+[<tt>--execute-continue</tt> _code_ (-p)]
+    Execute some Ruby code, then continue with normal task processing.
+
+[<tt>--help</tt>  (-H)]
+    Display some help text and exit.
+
+[<tt>--libdir</tt> _directory_  (-I)]
+    Add _directory_ to the list of directories searched for require.
+
+[<tt>--nosearch</tt>  (-N)]
+    Do not search for a Rakefile in parent directories.
+
+[<tt>--prereqs</tt>  (-P)]
+    Display a list of all tasks and their immediate prerequisites.
+
+[<tt>--quiet</tt> (-q)]
+    Do not echo commands from FileUtils.
+
+[<tt>--rakefile</tt> _filename_ (-f)]
+    Use _filename_ as the name of the rakefile. The default rakefile
+    names are +rakefile+ and +Rakefile+ (with +rakefile+ taking
+    precedence). If the rakefile is not found in the current
+    directory, +rake+ will search parent directories for a match. The
+    directory where the Rakefile is found will become the current
+    directory for the actions executed in the Rakefile.
+
+[<tt>--rakelibdir</tt> _rakelibdir_ (-R)]
+    Auto-import any .rake files in RAKELIBDIR. (default is 'rakelib')
+
+[<tt>--require</tt> _name_ (-r)]
+    Require _name_ before executing the Rakefile.
+
+[<tt>--rules</tt>]
+    Trace the rules resolution.
+
+[<tt>--silent (-s)</tt>]
+    Like --quiet, but also suppresses the 'in directory' announcement.
+
+[<tt>--system</tt> (-g)]
+    Use the system wide (global) rakefiles. The project Rakefile is
+    ignored. By default, the system wide rakefiles are used only if no
+    project Rakefile is found. On Unix-like system, the system wide
+    rake files are located in $HOME/.rake. On a windows system they
+    are stored in $APPDATA/Rake.
+
+[<tt>--no-system</tt> (-G)]
+    Use the project level Rakefile, ignoring the system-wide (global)
+    rakefiles.
+
+[<tt>--tasks</tt> (-T)]
+    Display a list of the major tasks and their comments.  Comments
+    are defined using the "desc" command.
+
+[<tt>--trace</tt> (-t)]
+    Turn on invoke/execute tracing. Also enable full backtrace on
+    errors.
+
+[<tt>--usage</tt> (-h)]
+    Display a usage message and exit.
+
+[<tt>--verbose</tt> (-v)]
+    Echo the Sys commands to standard output.
+
+[<tt>--version</tt> (-V)]
+    Display the program version and exit.
+
+In addition, any command line option of the form
+<em>VAR</em>=<em>VALUE</em> will be added to the environment hash
+<tt>ENV</tt> and may be tested in the Rakefile.
