Switches are: (taken from the help of the original executable)
  -b       Toggle background load status off/on.
  -c:char  Specify sound card id letter.
  -g       Stay in graphics mode on exit.
  -h[:ex]  Disable EMS/XMS high memory support.
  -i       Switch sound interrupts mode off/on.
  -j       Wait for music to finish at end.
  -k       Keystroke jumps to end instead of abort.
  -m       Operate in non-MADS mode.
  -o:xxx   Specify opening special effect.
  -p       Switch MADS path mode to CONCAT.
  -r[:abn] Resynch timer (always, beginning, never).
  -s:file  Specify sound file.
  -u[:...] Use DMA speech [optional: addr,type,irq,drq].
  -w       Toggle white bars off/on.
  -x       Exit immediately after last frame.
  -y       Do not clear screen initially
  -z       Display statistics after run.

  Opening special effects are:
  0: no effect
  1: fade in
  2: fade in (looks to be the same as 1)
  3: box in from bottom left (unused)
  4: box in from bottom right (unused)
  5: box in from top left (unused)
  6: box in from top right (unused)
  7: pan in from left to right
  8: pan in from right to left
  9: circle in (new scene appears in a circle that expands)

  Animview is ran like this from the original games:
  animview.exe @resfilename -c:P,220,20 -u:220,20,07,01 -p -a:mainmenu -p

  Note that the first -p is necessary to watch the animation, otherwise
  the program just exits

  To watch an animation within the *.res file, just run animview like this:
  animview.exe -x -r:b -o:2 animfilename -p
