Is package.use a file or a directory? If it's a file, convert it to a 
directory (you can just put the existing package.use file in the new 
directory).

Then make sure every time you add new use flags they're either in a file 
dedicated to a particular package, or they're in a dated file and refer 
to particular package versions. That dated file, when etc-update wants 
to update package.use, I just rename its temporary file into a proper 
dated file, rather than let it mess with a file it's chosen at random.

That way, you can delete packages you no longer use, clear out old 
package/use combos, and generally keep things tidy.

And when you're trying to fix something, that all goes in one file you 
can ditch when it's all gone wrong :-)
