Beagle filter for Gentoo ebuilds

[Pat Double <pat patdouble com>]

I've written a filter for Gentoo Linux ebuilds. The main goal is to extract 
information like the title, version, description, etc. It was really easy to 
write. I'd appreciate comments (I'm a Java developer, so I'm sure there are 
some bad things I've done with C# here ;). Any chance this could get included 
in the beagle distribution? How do I go about that, file a bug?

Thanks.
