"Gruff is a beautiful graphing library for Ruby using RMagick. Plot multiple datasets in color or implement your own colorful theme. Line graphs available initially. Can be easily extended to draw bar, pie, or other types of graphs." I simply changed the filename and license of dev-ruby/syntax-1.0.0.ebuild to get gruff onto my system. I'm attatching the ebuild. The rubygems eclass is really great!

Committed gruff, with some modifications. Thanks for the report.
