Remove the SGI demos. These were all ancient and nobody cared enough.

-# Manipulate the time base of CMIF movies
-
-
-# Possibilities:
-#
-# - resample at a fixed rate
-# - divide the time codes by a speed factor (to make it go faster/slower)
-# - drop frames that are less than n msec apart (to accommodate slow players)
-
-
-# Usage:
-#
-# Vtime [-m msec] [-r msec] [-s speed] [infile [outfile]]
-
-
-# Options:
-#
-# -m n : drop frames closer than n msec (default 0)
-# -r n : regenerate input time base n msec apart
-# -s speed : speed change factor after other processing (default 1.0)
-# infile : input file (default film.video)
-# outfile : output file (default out.video)
