My bad, I thought the `help' target was a GNU standard. `make help' would display a one-line help about the various available targets: # make all # make install # make TAGS # make clean (or make mostlyclean) # make distclean # make maintainer-clean # make extraclean # make bootstrap (Taken from INSTALL, not from the actual Makefile.) If I'm not confused, the last two targets are not in the GNU standards (`bootstrap' and `extraclean'). Documenting `make extraclean' is not important IMO but documenting `make bootstrap' could be: there are often questions on emacs-devel which are answered by "You need to `make bootstrap'." I guess `make help' could give a better exposure to this option? -- Bastien ^ permalink raw reply [flat|nested] 13+ messages in thread

I think you should feel free to add such a target if you think it will be useful to people.

It's not always easy to find the doc corresponding to a given target, so I think it would indeed be a good idea to make "make help" return some useful info. I also think it would be a valuable addition to the GNU coding standards. Just like all commands should accept a "--help", it would make sense for the main Makefile to do something useful with "make help". Stefan ^ permalink raw reply [flat|nested] 13+ messages in thread
