ACK

I /thought/ that was the case.  But I wanted to double check that there 
wasn't something else filed away that needed to match before I edited 
the file.

It seems as if the regenworld script adds things that it finds from 
/var/log/emerge.log that aren't themselves dependencies of something 
else.  Thus it the world file is cleaner than if all installed packages 
were in the world file.

However, there are still some things that aren't dependencies of other 
things that are listed that are no longer needed.

The world file is 279 lines long.  I'm just going to go through the file 
by hand and identify every package listed and make a judgment call if I 
know if it needs to be on the system or not.  If it does, then I'll 
leave it.  If it doesn't then I'll remove it from the world file and let 
emerge decide if it needs to stay or not.  There's a massive --depclean 
in this systems future.

ACK
