Debconf5 DVD builder

Copyright 2005 Ben Hutchings
See "copyright" file for licence terms.

You will need the following packages installed:
- dvdauthor
- mencoder (available from Marillat)
- mjpegtools (availale from Marillat)
- mpegdemux
- mkisofs
- netpbm (for NTSC only)
- python
- python-gd
- ttf-bitstream-vera

You will also need the video files from dc5video.debian.net (as listed
in the Makefile) under a sub-directory called dc5video.debian.net.
Define the make variable DOWNLOAD if you want to have these downloaded
automatically as needed.

You MUST use a UTF-8 locale when generating menu VOBs.  The rule for
them will check this.

Finally, you will need a lot of disk space:
- recoded video files: 8 GB for each of PAL and NTSC
- temporary DVD tree: 5 GB for single-layer, 8 GB for dual-layer
- DVD images: 8 GB for each set

By default, this will generate single-layer disc images with video at
PAL resolutions. Define the make variable NTSC if you want to generate
video at NTSC resolutions (currently this is broken; see TODO). 
Define the make variable DUAL_LAYER if you want to generate dual-layer
disc images.
