  mplayer     is used to extract a still image from MPEG files, and
	      to extract audio from VOICE files.
	      If missing, no stills will be produced, and VOICE files
	      will remain silent.

# Image::Magick doesn't build, so do not depend.
print STDERR <<EOD;

  Image::Magick  is used for various image manipulations.
