I like the description "some sort of intelligent matching"...  Sounds

I was copying your pacsearch script!

The saying that "perl is like an explosion in an ascii factory" pretty 
much describes how I see perl...  If/when I add the pkgver matching then 
this will disappear.

Also, I think I will rename the script "paclist" as that is perhaps 
slightly better that "repopkg".  It also has the "pac" prefix which 
matches pacsearch and pacdiff.
