# TODO:
# - Make more checks about whether the “things” built and installed are C.
# (stuff *will* break if you add non-C things as targets)
# - Clean some more (or a lot). I mean, this script could even be reused if
# it were cleaner, more readable and somewhat more documented.
# - Using subdirs creates trouble. Really. Dont do it unless its for
# completely separate, independent sub-projects.
# Also, theyre unmaintained and probably broken by now.
#
# WARNINGS and LIMITATIONS:
# - Using a relative path in DESTDIR= *will* fail.
