JRuby 1.6.5

JRuby 1.6.5 brings an enhanced and advantageous program which provides a complete set of core "builtin" classes and syntax for the Ruby language, as well as most of the Ruby Standard Libraries. The standard libraries are mostly Ruby's own complement of .rb files, but a few that depend on C language-based extensions have been re-implemented. Some are still missing, but the providers hope to implement as many as is feasible and allows the embedding of the interpreter into any Java application.

Enhancements:

• Many –1.9 encoding issues resolved
• .jrubyrc support for storing convenient execution options
