# IMPORTANT NOTE:
# This script no longer accepts an optional argument.
# It was removed by the same person who added it -- me, drobbins -- when I optimized
# bootstrap to complete 20 mins to 2 hours faster, depending on CPU. I did this by 
# merging both stages of bootstrap into a single stage. We no longer compile gcc and
# binutils twice. Doing this is unnecessary and a holdover from very early versions
# of Gentoo, where we were being ultra-paranoid.
