This program requires some helper programs.

  jpegtran    will be used to rotate JPEG files loslessly.
	      If missing, JPEG files will be rotated by ImageMagick,
	      with possible loss of information.

checkexec("jpegtran");

print STDERR <<EOD;

  mencoder    is needed to manipulate MPEG files.
	      If missing, MPEG movies will be copied, and cannot be rotated.
EOD
checkexec("mencoder");

print STDERR <<EOD;

  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.
