NAME

     cmplayer - application for playback of continuous media


SYNOPSIS

     cmplayer [options] [filename]


DESCRIPTION

     Cmplayer is an application for the  playback  of  video  and
     audio  data.   It  is a Tcl/Tk script that requires a cmwish
     binary (a wish linked with the CMT Toolkit) in order to exe-
     cute.

     If a filename is supplied, cmplayer attempts  to  open  that
     file  for  playback.  The following formats can be played by
     the cmplayer:

          CMT movie scripts
          Sun/Next .au files
          MPEG encoded video files

     If the file ~/.cmplayerrc exists, it is  sourced  as  a  Tcl
     script at startup.  It is often useful to change directories
     or set options in this file.
