# This wrapper around the colm program (and bootstrap programs) allows us to
# limit ourselves to one output file per makefile rule. It packs up multiple
# colm output files into one pack file, which is used as an intermediate file.
# We can extract the individual files from the pack one at a time, in separate
# rules.
#
# Ultimately this functionality should be rolled into the colm program itself.
# Until that is complete, this wrapper exists.
