* 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 machines)

* How to compile and install

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

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

  2. Edit defines.h if you need.  Probably this step will not need.

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

     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
     ext/Setup.

  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'

     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.
