here's take two. if someone could tell me a simple way to get the
category given a package name, including a way to detect ambiguous
names, i could drop the dependency on app-portage/udept.
anyways it now supports disabling more than one FEATURE and defaults
to appending to the env file with an -o option for overwriting.
it won't rape your dog though it may try. it could also probably be
rewritten using nothing but pure sh, awk, perl, or GWBASIC, but i
think it does what i want it to. ;)
