Summary     : An interpreter of object-oriented scripting language

files and to do system management tasks (as in Perl).  It is simple,
straight-forward, and extensible.

Update Information:

A secrity vulnerability is found on WEBrick module in Ruby  currently shipped on
Fedora 12 that WEBrick lets attackers   to inject malicious escape sequences to
its logs, making it  possible for dangerous control characters to be executed on
a victim's terminal emulator. This issue has now been tagged as  CVE-2009-4492.
Also currently have_library() function in mkmf.rb always  requires ruby's static
archive to function correctly despite  that ruby shared library is also
provided.    This new rpm will fix these issues.
