Excellent, then we are working toward similar ends: the invasion of the Jav=
a
world by Rubyists. Please feel free to ask questions on the JRuby mailing
lists at sf.net/projects/jruby and let us know how things are working out
for you. The compatibility issue is one of special concern for us...we'd
like to be able to run everything Ruby out of the box, and perhaps this is
not something Jython can claim today.
