-* What's shell.rb?
+=begin
 
-It realizes a wish to do execution of command and filtering like
-sh/csh. However, Control statement which include sh/csh just uses
-facility of ruby.
+= What's shell.rb?
 
-* Main classes
-** Shell
+It realizes a wish to do execution of commands with filters and pipes
+like sh/csh by using just native facilities of ruby.
 
-All shell objects have a each unique current directory. Any shell object
-execute a command on relative path from current directory.
+= Main classes
 
-+ Shell#cwd/dir/getwd/pwd current directory
-+ Shell#system_path	  command path
-+ Shell#umask		  umask
+== Shell
 
-** Filter
+Every shell object has its own current working directory, and executes
+each command as if it stands in the directory.
 
-Any result of command exection is a Filter. Filter include Enumerable,
-therefore a Filter object can use all Enumerable facility.
+--- Shell#cwd
+--- Shell#dir
+--- Shell#getwd
+--- Shell#pwd
 
-* Main methods
-** Command definition
+      Returns the current directory
 
-For executing a command on OS, you need to define it as a Shell
-method.  
+--- Shell#system_path
 
-notice) Also, there are a Shell#system alternatively to execute the
-command even if it is not defined.
+      Returns the command search path in an array
 
-+ Shell.def_system_command(command, path = command)
-Register command as a Shell method 
+--- Shell#umask
 
-++ Shell.def_system_command "ls"
-   define ls
-++ Shell.def_system_command "sys_sort", "sort"
-   define sys_sort as sort
+      Returns the umask
 
-+ Shell.install_system_commands(pre = "sys_")
+== Filter
 
-Define all command of default_system_path. Default action prefix
-"sys_" to the method name.
+Any result of command exection is a Filter.  Filter include
+Enumerable, therefore a Filter object can use all Enumerable
+facilities.
 
-** 生成
+= Main methods
 
-+ Shell.new
-Shell creates a Shell object of which current directory is the process
-current directory.
+== Command definitions
 
-+ Shell.cd(path)
-Shell creates a Shell object of which current directory is <path>.
+In order to execute a command on your OS, you need to define it as a
+Shell method.
 
-** Process management
+Alternatively, you can execute any command via Shell#system even if it
+is not defined.
 
-+ jobs
-The shell returns jobs list of scheduling.
+--- Shell.def_system_command(command, path = command)
 
-+ kill sig, job
-The shell kill <job>.
+      Defines a command.  Registers <path> as a Shell method
+      <command>.
 
-** Current directory operation
+      ex)
+      Shell.def_system_command "ls"
+        Defines ls.
 
-+ Shell#cd(path, &block)/chdir
-The current directory of the shell change to <path>. If it is called
-with an block, it changes current directory to the <path> while its
-block executes.
+      Shell.def_system_command "sys_sort", "sort"
+        Defines sys_sort as sort.
 
-+ Shell#pushd(path = nil, &block)/pushdir
+--- Shell.undef_system_command(command)
 
-The shell push current directory to directory stack. it changes
-current directory to <path>. If the path is omitted, it exchange its
-current directory and the top of its directory stack. If it is called
-with an block, it do `pushd' the <path> while its block executes.
+      Undefines a commmand
 
-+ Shell#popd/popdir
-The shell pop a directory from directory stack, and its directory is
-changed to current directory.
+--- Shell.alias_command(ali, command, *opts) {...}
 
-** ファイル/ディレクトリ操作
+      Aliases a command.
 
-+ Shell#foreach(path = nil, &block)
-Same as:
-  File#foreach (when path is a file)
-  Dir#foreach (when path is a directory)
+      ex)
+        Shell.alias_command "lsC", "ls", "-CBF", "--show-control-chars"
+        Shell.alias_command("lsC", "ls"){|*opts| ["-CBF", "--show-control-chars", *opts]}
 
-+ Shell#open(path, mode)
-Same as:
- File#open(when path is a file)
- Dir#open(when path is a directory)
+--- Shell.unalias_command(ali)
 
-+ Shell#unlink(path)
-Same as:
- Dir#open(when path is a file)
- Dir#unlink(when path is a directory)
+      Unaliases a command.
 
-+ Shell#test(command, file1, file2)/Shell#[command, file1, file]
-Same as file testing function test().
-ex)
-    sh[?e, "foo"]
-    sh[:e, "foo"]
-    sh["e", "foo"]
-    sh[:exists?, "foo"]
-    sh["exists?", "foo"]
-
-+ Shell#mkdir(*path)
-Same as Dir.mkdir(its parameters is one or more)
-
-+ Shell#rmdir(*path)
-Same as Dir.rmdir(its parameters is one or more)
-
-** Command execution
-+ System#system(command, *opts)
-The shell execure <command>.
-ex)
-  print sh.system("ls", "-l")
-  sh.system("ls", "-l") | sh.head > STDOUT
-
-+ System#rehash
-The shell do rehash.
-
-+ Shell#transact &block
-The shell execute block as self.
-ex)
-  sh.transact{system("ls", "-l") | head > STDOUT}
-
-+ Shell#out(dev = STDOUT, &block)
-The shell do transact, and its result output to dev.
-
-** Internal Command
-+ Shell#echo(*strings)
-+ Shell#cat(*files)
-+ Shell#glob(patten)
-+ Shell#tee(file)
-
-When these are executed, they return a filter object, which is a
-result of their execution.
-
-+ Filter#each &block
-The shell iterate with each line of it.
-
-+ Filter#<(src)
-The shell inputs from src. If src is a string, it inputs from a file
-of which name is the string. If src is a IO, it inputs its IO.
-
-+ Filter#>(to)
-The shell outputs to <to>. If <to> is a string, it outputs to a file
-of which name is the string. If <to>c is a IO, it outoputs to its IO.
-
-+ Filter#>>(to)
-The shell appends to <to>. If <to> is a string, it is append to a file
-of which name is the string. If <to>c is a IO, it is append to its IO.
-
-+ Filter#|(filter)
-pipe combination
-
-+ Filter#+(filter)
-filter1 + filter2 output filter1, and next output filter2.
