	A simple tool for performing substitutions on the source files of the
	compiler.

compiler/*.m:
	Change the names of the get predicates operating on module_infos to
	include "get" in the name, for uniformity. This was done mostly by
	the following sed script, with some manual cleanup afterwards to reduce
	excessive line lengths.
