emerge -v thissocoolapplication

<brings in plenty of deps not used by another package, and adds
thiscoolapplication to the world file>

emerge -v --unmerge thiscoolapplicaton

<removes thiscoolapplication from the comp and the world file>

emerge -v depclean

<lists things broughtin but no longer found to be needed>

genlop -lunr|tail

<lists recently installed stuff>

emerge -v --unmerge <apps emerged before thiscoolapplication and not
needed according to depclean>
