* What's Ruby

Ruby is the interpreted scripting language for quick and
easy object-oriented programming.  It has many features to
process text files and to do system management tasks (as in
Perl).  It is simple, straight-forward, and extensible.

* Features of Ruby

  + Simple Syntax
  + *Normal* Object-Oriented features(ex. class, method calls)
  + *Advanced* Object-Oriented features(ex. Mix-in, Singleton-method)
  + Operator Overloading
  + Exception Handling
  + Iterators and Closures
  + Garbage Collection
  + Dynamic Loading of Object files(on some architecture)
  + Highly Portable (works on many Unix-like/POSIX compatible platforms
    as well as Windows, Mac OS X, BeOS etc.)

* How to get Ruby

The Ruby distribution files can be found in the following FTP site:

The trunk of the Ruby source tree can be checked out with the
following command:

  $ svn co ruby

There are some other branches under development.  Try the following
command and see the list of branches:

  $ svn ls

* Ruby home-page

The URL of the Ruby home-page is:

* Mailing list

There is a mailing list to talk about Ruby.

* How to compile and install

This is what you need to do to compile and install Ruby:

  1. If ./configure does not exist or is older than,
     run autoconf to (re)generate configure.

  2. Run ./configure, which will generate config.h and Makefile.

     Some C compiler flags may be added by default depending on your
     environment.  Specify optflags=.. and warnflags=.. as necessary
     to override them.

  3. Edit defines.h if you need.  Usually this step will not be needed.

  4. Remove comment mark(#) before the module names from ext/Setup (or
     add module names if not present), if you want to link modules

     If you don't want to compile non static extension modules
     (probably on architectures which does not allow dynamic loading),
     remove comment mark from the line "#option nodynamic" in

  5. Run make.

  6. 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).

  7. Run 'make install'

     This command will create following directories and install files
     onto them.

       * ${DESTDIR}${prefix}/bin
       * ${DESTDIR}${prefix}/include/ruby-${MAJOR}.${MINOR}.${TEENY}
       * ${DESTDIR}${prefix}/include/ruby-${MAJOR}.${MINOR}.${TEENY}/${PLATFORM}
       * ${DESTDIR}${prefix}/lib
       * ${DESTDIR}${prefix}/lib/ruby
       * ${DESTDIR}${prefix}/lib/ruby/${MAJOR}.${MINOR}.${TEENY}
       * ${DESTDIR}${prefix}/lib/ruby/${MAJOR}.${MINOR}.${TEENY}/${PLATFORM}
       * ${DESTDIR}${prefix}/lib/ruby/site_ruby
       * ${DESTDIR}${prefix}/lib/ruby/site_ruby/${MAJOR}.${MINOR}.${TEENY}
       * ${DESTDIR}${prefix}/lib/ruby/site_ruby/${MAJOR}.${MINOR}.${TEENY}/${PLATFORM}
       * ${DESTDIR}${prefix}/lib/ruby/vendor_ruby
       * ${DESTDIR}${prefix}/lib/ruby/vendor_ruby/${MAJOR}.${MINOR}.${TEENY}
       * ${DESTDIR}${prefix}/lib/ruby/vendor_ruby/${MAJOR}.${MINOR}.${TEENY}/${PLATFORM}
       * ${DESTDIR}${prefix}/lib/ruby/gems/${MAJOR}.${MINOR}.${TEENY}
       * ${DESTDIR}${prefix}/share/man/man1
       * ${DESTDIR}${prefix}/share/ri/${MAJOR}.${MINOR}.${TEENY}/system

     If Ruby's API version is `x.y.z', the ((|${MAJOR}|)) is `x', the
     ((|${MINOR}|)) is `y', and the ((|${TEENY}|)) is `z'.

     NOTE: teeny of the API version may be different from one of
     Ruby's program version

     You may have to be a super user to install ruby.

If you fail to compile ruby, please send the detailed error report with
the error log and machine/OS type, to help others.
