7 # Ah! gcc folks are kind of 'different': they store the tarballs in
8 # subdirectories of the same name! That's because gcc is such /crap/ that
9 # it is such /big/ that it needs being splitted for distribution! Sad. :-(
10 # Arrgghh! Some of those versions does not follow this convention:
11 # gcc-3.3.3 lives in releases/gcc-3.3.3, while gcc-2.95.* isn't in a
12 # subdirectory! You bastard!
