From 6acec0380bfcd5e3f91c9100bf4d415db8f7acfd Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Ren=C3=A9=20Scharfe?= Date: Wed, 28 Sep 2011 19:44:30 +0200 Subject: parseopt: add OPT_NOOP_NOARG Add OPT_NOOP_NOARG, a helper macro to define deprecated options in a standard way. The help text is taken from the no-op option -r of git revert. The callback could be made to emit a (conditional?) warning later. And we could also add OPT_NOOP (requiring an argument) etc. as needed.
