ernstki / !Makefile with built in help.md

Last active December 7, 2025 11:48

Auto-generated 'make help' from comments on Makefile targets

This replaces an earlier Perl version I'd been using for years, but I started thinking, hey, Bash can do all that. It's about ten lines longer than the Perl version, but possibly more readable.
