Any tool to manipulate /etc/portage/package.use?

[shallpion]

I always use vim + echo to edit this file, until today I read an article by a poor guy who carelessly flushed this package.use by echo "balabala...">/etc/portage/package.use .... Is there any small tool to manipulate this file, safely and conveniently? Thanks.

Sounds like the poor guy made a mistake similar to using "rm -rf /". With power comes responsibility. Certainly all he would have to do is copy his package.use file from his backups to resolve the situation.

Or use the package.use directory feature like package.keywords for kde4.
