Usage: 
  dvd-menu -t <titleset1> ... -t <titlesetN>
  -f <xmlfile1> ... -f <xmlfileN> [-o output_directory]
  [-n "menu title"] [-e <embed image>] [-L]
  [-b <background jpeg>] [ -a <menu audio file> ] [-p]
  [-c] [-D] [-W] [-mp2] [-iso] [-nomenu] 

Description: 
	Creates a simple vmgm menu with buttons that
	link to the mpeg files in the specified 
	dvdauthor-compatible xml files. 
	
Options: 
 -t <titleset1> -t <titleset2> ... -t <titlesetN>
	Name of each title.  Each string will be used for 
	the button menu corresponding to each xmlfile.
	This sets the order of the menu buttons!

 -f <xmlfile1> <xmlfile2> ...
	Name of each titleset xml file.  You can use
	dvd_slideshow to generate one for each slideshow
	or you can create your own for a simple mpeg2
	file.

 [-e <embedded image>]
	Embed a jpeg image in the middle of the screen.
	If one image is passed for each button text, 
	That image will be shown as each button is active.

 [-o <output directory>]
	Directory where the output dvd file system resides

 [-b <background jpeg>]
	Image to put in the background of the menu.

 [-a <audiofile>]
	Audio file to use in the background of the
	menu.  The full audio file will keep looping.
	Supports mp3, ogg, or wav.

 [-mp2]
        Use MP2 audio by default.  AC3 seems to be more stable
	in hardware players, but requires ffmpeg.

 [-n "dvd_title"]
        This string will be placed on the top of the
        menu page.

 [-p]
        Use PAL format instead of NTSC (untested initial support)

 [-c]
        Use continuous method.  Each video plays one after another.

 [-W]
        Do not generate 50% white background behind menu text.

 [-L]
        Use low quality mode for compatibility with the same option
	in dvd-slideshow.  This renders half-resolution menus.

 [-D]
        Do not call dvdauthor at the end.  Useful when you want
	to edit your own xml file and pass it to dvdauthor by hand.

 [-iso]
        Create iso image with mkisofs when finished.

 [-nomenu]
        Do not create a menu.  Useful for just finishing the 
	dvdauthor xml file from one video that you want to just
	start playing when the user puts it into a dvd player.

 [-nocleanup]
        Save files in temp directory for debugging.

 -h or -help 
   Prints this help. 

Requires:
	dvdauthor 0.6.11
	sox
	mjpegtools  (mp2enc, mpeg2enc, ppmtoy4m)
	ImageMagick (convert)
 '
}

if [ $# -lt 1 ]; then
	help
	exit 1
fi

# [-button <button image.jpg>]
#	Use image.jpg for a highlight image button.
#	The text from -t <titleset> will be placed underneath.
#	Pass one -b <image.jpg> for each titleset xml file.
