Here's a simple python script for you. You'll need python 2.2 if you
haven't got it already. Feed it the output of "pkg_info -a -R" on
standard in, and it'll output the package names of all packages that
aren't required by other packages.
Don't forget that you may have packages which are only required by
packages that you don't want, so you need to iterate over the deletion
process multiple times.
