[xiph-commits] r3628 - liboggz/trunk/src/tools

[conrad at svn.annodex.net]

Author: conrad
Date: 2008-07-08 08:37:47 -0700 (Tue, 08 Jul 2008)
New Revision: 3628

Added:
   liboggz/trunk/src/tools/oggz.c
Modified:
   liboggz/trunk/src/tools/Makefile.am
Log:
add a wrapper "oggz" tool, so that commands like the following work:
  $ oggz dump file.ogv  -- runs "oggz-dump file.ogv"
  $ oggz help info      -- runs "man oggz-info", or "oggz-info --help" on win32
  $ oggz                -- prints a list of common oggz-tools

(so you can use a space instead of a hyphen, like with git)
