+= How to build ruby using Borland C++
+
+== Requirement
+
+(1) Borland C++ 5.0 or later.
+
+(2) If you want to run `((%make clean%))' or `((%make distclean%))'
+    properly, you must install UNIX compatible `((%rm%))' command on
+    your ((|PATH|)).
+
+(3) Please set environment variable (({INCLUDE})), (({LIB})), (({PATH}))
+    to run required commands properly from the command line.
+
+    Note: building ruby requires following commands.
+     * make
+     * bcc
+     * tlib
+     * ilink
+
+== How to compile and install
+
+(1) Execute bcc32\configure.bat on your build directory.
+     ex. c:\ruby-1.6.7>bcc32\configure.bat
+     
+(2) Change ((|RUBY_INSTALL_NAME|)) and ((|RUBY_SO_NAME|)) in (({Makefile}))
+    if you want to change the name of the executable files. 
+    And add ((|RUBYW_INSTALL_NAME|)) to change the name of the
+    executable without console window if also you want.
+
+(3) Run `((%make%))'
+
+(4) Run `((%make test%))'
+
+(5) Run `((%make DESTDIR=<install_directory> install%))'
+
+    This command will create following directories and install files onto them.
+      * <install_directory>\bin
+      * <install_directory>\lib
+      * <install_directory>\lib\ruby
+      * <install_directory>\lib\ruby\<MAJOR>.<MINOR>
+      * <install_directory>\lib\ruby\<MAJOR>.<MINOR>\<PLATFORM>
+      * <install_directory>\lib\ruby\site_ruby
+      * <install_directory>\lib\ruby\site_ruby\<MAJOR>.<MINOR>
+      * <install_directory>\lib\ruby\site_ruby\<MAJOR>.<MINOR>\<PLATFORM>
+      * <install_directory>\man\man1
+    If Ruby's version is `x.y.z', the ((|<MAJOR>|)) is `x' and the ((|<MINOR>|)) is `y'.
+    The ((|<PLATFORM>|)) is usually `(({i586-bccwin32}))'.
+
+== Icons
+
+Any icon files(*.ico) in the build directory, directories specified with
+((|icondirs|)) make variable and (({win32})) directory under the ruby
+source directory will be included in DLL or executable files, according
+to their base names.
+    $(RUBY_INSTALL_NAME).ico or ruby.ico   --> $(RUBY_INSTALL_NAME).exe
+    $(RUBYW_INSTALL_NAME).ico or rubyw.ico --> $(RUBYW_INSTALL_NAME).exe
+    the others                             --> $(RUBY_SO_NAME).dll
+
+Although no icons are distributed with the ruby source or in the official 
+site, you can use anything you like. For example, followings are written 
+in Japanese, but you can download at least.
+
+* ((<URL:http://member.nifty.ne.jp/ueivu/rubyico.html>)) or
+  ((<zipped icons|URL:http://member.nifty.ne.jp/ueivu/Ruby_ico.zip>))
+* ((<URL:http://homepage1.nifty.com/a_nakata/ruby/>)) or
+  ((<icon itself|URL:http://homepage1.nifty.com/a_nakata/ruby/RubyIcon.ico>))
+
+== Build examples
+
+* Build on the ruby source directory.
+
+  ex.)
+    ruby source directory:  C:\ruby
+    build directory:        C:\ruby
+    install directory:      C:\usr\local
+
+    C:
+    cd \ruby
+    bcc32\configure
+    make
+    make test
+    make DESTDIR=/usr/local install
+
+* Build on the relative directory from the ruby source directory.
+
+  ex.)
+    ruby source directory:  C:\ruby
+    build directory:        C:\ruby\bccwin32
+    install directory:      C:\usr\local
+
+    C:
+    cd \ruby
+    mkdir bccwin32
+    cd bccwin32
+    ..\bcc32\configure
+    make
+    make test
+    make DESTDIR=/usr/local install
+
+* Build on the different drive.
+
+  ex.)
+    ruby source directory:  C:\src\ruby
+    build directory:        D:\build\ruby
+    install directory:      C:\usr\local
+
+    D:
+    cd D:\build\ruby
+    C:\src\ruby\bcc32\configure
+    make
+    make test
+    make DESTDIR=C:/usr/local install
+
+== Bugs
+
+You can ((*NOT*)) use a path name contains any white space characters as
+the ruby source directory, this restriction comes from the behavior of
+(({!INCLUDE})) directives of (({MAKE})).
+((- you may call it a bug. -))
