# This is the main Makefile. The two primary targets are "all", to build
# everything which can be built (except tests), and "clean" to remove all
# dependent files. In a repository clone, derived source files are generated
# and deleted as well.
#
# We distinguish between repository clones and source packages by the existence
# of make-files.sh scripts in various subdirectories.
