+Usage: ${0##*/} [OPTIONS]
+Build emacs if needed or directed to.
+
+If you want this script to build a new version of emacs, you need to do
+2 things. 1: check it out in /a/opt/emacs. 2: Remove
+/a/opt/emacs-DISTRO_CODENAME. We don't test for the git repo to be a
+different version that the codename directory because the repo can be
+used for testing & development, randomly switching around version. Also,
+we might intentionally use a different version for different distro
+codenames.
+
+-h|--help  Print help and exit.
+
+Note: Uses util-linux getopt option parsing: spaces between args and
+options, short options can be combined, options before args.
