0.24 BugMaster's mod 3 (2014-9-4)
new options:
  -depth  specify input bit depth (default 8),
          >8 expects avisynth 16-bit hack input video
  -fps    overwrite input framerate
  -par    specify pixel aspect ratio
new supported value AUTO for -csp option which will try to detect input colorspace or convert to I420

0.24 BugMaster's mod 2 (2011-9-20)
merge 2 changes by Oka Motofumi (aka Chikuzen):
  added 128 KB file buffering for speed up
  use ffmpeg for huffyuv encoding instead of mencoder
added support for interlaced avs sources (it must be field-based instead of frame-based)
new option: -csp i420/i422/i444 for support of I422/I444 colorspaces output (AviSynth 2.6+ is required)

0.24 BugMaster's mod (2011-7-7)
replaced AviSynth C++ interface with C interface
compiles with GCC instead of MSVS
added call of 'Distributor' for multi-threaded scripts
calls avs_delete_script_environment at the end of work

0.24 (2005-3-4)
new option: -raw outputs raw I420 (omits yuv4mpeg headers)

0.23 (2005-1-26)

0.22 (2004-11-25)
