* How to get Ruby

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

   ftp://ftp.ruby-lang.org/pub/ruby/

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

   $ svn co http://svn.ruby-lang.org/repos/ruby/trunk/ ruby

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

   $ svn ls http://svn.ruby-lang.org/repos/ruby/branches/
