Re: [PATCH] Makefile: implement help target

How's this for a version without maintenance issues?

Something along these lines would be closer to what I had in mind,
actually.

Traditionally a multi-line sed command embed in Makefile has been
portability nightmare, which is a bit worrysome.

Isn't there a "makedoc" ala "perldoc" or "javadoc", by the way?

...
+#H# Show help for main make targets
+help:
+	@sed -n  -e '/^#H#/ {N'\
+		-e 's/^#H# \(.*\)\n\([a-z0-9_-]*\):.*/\2 \1/p'\
+		-e '}' <Makefile | sort --key=2 | while read target txt;\
+	do \
+		printf "%-20s: %s\n" "$$target" "$$txt"; \
+	done
