pngcrush-1.6.4
--------------
Pngcrush is an optimizer for PNG (Portable Network Graphics) files.
It can be run from a commandline in an MSDOS window, or from a UNIX
or LINUX commandline.
Its main purpose is to reduce the size of the PNG IDAT datastream by trying
various compression levels an PNG filter methods. It also can be used
to remove unwanted ancillary chunks, or to add certain chunks including
gAMA, tRNS, iCCP, and textual chunks.
The author of pngcrush is Glenn Randers-Pehrson, glennrp@users.sf.net

NOTES:
- math functions are single precision, mail me if you feel that
you need double precision.
- there is stack overflow detection, but to avoid unexpected program
termination set the 'stack 50000'.
dont set it below 16384, auto stack extension is broken and there is
nothing i can do about it just keep using fixed stack to override
auto extension.
- 68040 version have its dependencies optimized for this cpu
as well.
- to see available options, issue the command in cli without any args.
- also note that by default it generates MNG's(no idea what is this),
that are unreadable by most viewers, use '-itxt PNG|PNG' to generate
files with the correct header.
