-------

   This is a tiny application for displaying the TV picture
 through the linear frame buffer on a 3dfx Voodoo Graphics
 based 3D accelerator card and controlling the TV tuner
 on the bttv card.

   Using glidetv, you don't need to have X windows running,
 and you can easily have a full screen TV display without
 playing with X server and window manager configuration.

   Before running glidetv, you need to have xtvscreen working
 (check out it's documentation), and the glide library
 installed and working (use something like GLQuake or Quake2
 for verifying that 8-). The glide library can be downloaded
 from http://www.3dfx.com/software/download_glidel.html ...

   Use xtvscreen to find the channels and save the channel list
 to ~/.xtvrc using the 'save' button... glidetv will use
 that information for the channel list.

 glidetv is able use your soundcard's mixer to adjust the audio
 volume. (with soundcard support enabled glidetv is also able
 to eliminate the loud noise during channel-switch)
 On exit the original volume is restored.
