# and in places we scrape data from that file instead of duplicating it here.

#prep
# Before running this script, you should either set $SOURCES to a directory
# containing the binutils/gcc/gdb/make tarballs or put them in the current
# directory, and set $PATCH to a suitable version of patch (one that can
# parse patches in unidiff format and that line-terminates output correctly).
