I think I'll just stick with what I know. For now, I'm just doing 'emerge info | grep USE' 
to get a complete list of USE flags. As for the DEPEND line, I'm using a regex to extract 
each item, although its not going too well.

[code]
while($deplist =~ /((\w+\?)?) (\(?) (\S+) (\)?)/cg) {
   print "$2 - $4\n";
}
[/code]

which is supposed to pull apart a string like:

nls? ( sys-devel/gettext ) media-sound/cdparanoia gif? ( media-libs/giflib 
media-libs/libungif )

and pull out each 'key? ( value )', 'key? ( value value )', or just 'value' where its 
alone. Anyone have any idea where I'm going wrong?
