After the 0.2.206 release, Alan Lefor reported that the `--version' option does not show in the output of `--help' on his Mac OS X (10.12.4) machine. However, it worked on the Scientific Linux that was installed on a virtual machine within the Mac OS X.

This was not a problem in Gnuastro 0.2.28 on Mac OS X.

The `--version' option (as well as the `--help' and `--usage' options) is not actually controlled by Gnuastro but by the GNU C Library's Argp routines (Which Gnuastro implements through Gnulib's implementation so it can be usable on non GNU systems also).

The only major change from version 0.2.28 that I can think of now is a modification in the options structure of Argp to allow more information for each option in bootstrap.conf (the part that discusses `argp_option'). However, I can't see how can be the cause of this Mac OS X-only behavior. Most probably it is something else.
