# SKELETONKEY — top-level Makefile (Phase 1)
|
|
#
|
|
# Builds one binary `skeletonkey` linked from:
|
|
# - core/ module interface + registry
|
|
# - modules/<f>/ one family per subdir, contributes objects to the
|
|
# final binary
|
|
# - skeletonkey.c top-level dispatcher
|
|
#
|
|
# Each family is currently flat (Phase 1 keeps copy_fail_family's
|
|
# absorbed DIRTYFAIL source in modules/copy_fail_family/src/).
|
|
# Future families register the same way: add their register_* call to
|
|
# skeletonkey.c's main() and add their src dir to MODULE_DIRS below.
