I updated the jruby ebuild for my first gentoo project. It's nearly
complete. I just have to test a few things. I added /usr/bin/jruby and
/usr/bin/jirb and some others. I also added /usr/share/jruby. I also
created an ebuild for jvyaml, a new dependancy in jruby. I tried to
contact the last maintainer (luckyduck@gentoo.org) but the email
bounced. I'd like to get some help checking over my work. I'd also like
to know the steps involved to get this into main. Here's the ebuilds:
