[MPlayer-cvslog] r34978 - in trunk: Makefile help/help_check.sh

[ib]

Author: ib
Date: Wed May 30 23:21:46 2012
New Revision: 34978

Log:
Add a Makefile target for testing the help message text headers.

This allows a syntax check without having to compile for each language,
but doesn't check the correctness of the used format specifiers though.

Added:
   trunk/help/help_check.sh   (contents, props changed)
Modified:
   trunk/Makefile
