-Oniguruma  ----   (C) K.Kosako <kosako@sofnec.co.jp>
-
-http://www.ruby-lang.org/cgi-bin/cvsweb.cgi/oniguruma/
-
-Oniguruma is a regular expression library.
-The characteristics of this library is that different character encodings
-for every regular expression object can be specified.
-(Supported character encodings: ASCII, UTF-8, EUC-JP, Shift_JIS)
-
-There are two ways of using of it in this program.
-
-  * Built-in regular expression engine of Ruby
-  * C library (supported APIs: GNU regex, POSIX, Oniguruma native)
-
-
-Install
-
-A. Install into Ruby
-
-   See INSTALL-RUBY.
-
-
-B. C library
-
- B1. Unix, Cygwin
-
-   1. ./configure
-   2. make
-   3. make install
-
-   (* uninstall:  make uninstall)
-
-  * test (EUC-JP)
-   4. make ctest
-
-
- B2. Win32 platform (VC++)
-
-   1. copy win32\config.h config.h
-   2. copy win32\Makefile Makefile
-   3. nmake
-
-        onig_s.lib:  static link library
-        onig.dll:    dynamic link library
-
-  * test (Shift_JIS)
-   4. copy win32\testc.c testc.c
-   5. nmake ctest

-API differences with Japanized GNU regex(version 0.12) of Ruby
-
-   + re_compile_fastmap() is removed.
-   + re_recompile_pattern() is added.
-   + re_alloc_pattern() is added.
-
-
-ToDo
-
-  1 support 16-bit and 31-bit encodings. (UCS-2, UCS-4, UTF-16)
-    (each encoding has meta-character code table?)
-
-  2 if-then-else. (?(condition)then), (?(condition)then|else)
-
-  ? variable meta characters.
-  ? implement syntax behavior REG_SYN_CONTEXT_INDEP_ANCHORS.
-  ? pattern encoding different with target.
-    (ex. UCS-2 Big Endian and UCS-2 Little Endian)
-  ? better acess to hash table.
-    non null-terminated key version st_lookup().
-    (but it needs to modify st.[ch])
-  ? character set specific POSIX bracket extensions. ([:hiragana:])
-  ? grep-like tool 'onigrep'. (variable syntax option etc..)
-  ? check invalid wide char value in WC2MB, WC2MB_FIRST on Ruby M17N.
-  ? define THREAD_PASS in regint.h as rb_thread_pass().
