 This program will convert the FILENAME JP4 movie to individual frames named
 FRAME-NNNNNN.dng, where NNNNNN will be replaced by the frame number starting
 at 1. Note that there is no need to specify the .dng extension on the frame
 name, it will be added automatically. If you want to save frames on a different
 directory, use something like DIRECTORY/FRAME, for example.

I'm going to use Launchpad as bug tracker for this project, please feel free to add bugs there, code is maintained both on Launchpad and SVN (Launchpad is a mirror a SVN).
