Just one small description (that I will add on a next release of
pngquant, when necessary) is this (or at least more or less like this):
Optimizers (like pngcrush) optimize the compression, usually losslessly.
pngquant quantizes colors down to 256 (or fewer) distinct RGBA
combinations, which is quite lossy. They're very different applications.
It's good to specify the difference between this PNG optimizer and other
optimizers available.
It can makes new PNG files 2 or 3 times smaller than the original.
The resulting image is very good. In some cases there are apparently no
visual difference between the original file and the new one.
Since PNG is getting very used (I see a lot of programs having the
default output as PNG and not GIF, JPG, TIFF, etc), could be very useful
having a program to makes some PNG file smaller.
pngcrunsh and pngquant, IMHO, should be included on med-imaging. If not
on Depends, at least on Recommends.

pngquant is already on NEW queue (it´s more than 1 month there). Philipp
Kern <pkern@debian.org> has sponsored this upload to me.
One thing that I don't know is why some packages take so long time to be
processed. Some programs stay only 1 day on NEW queue, while others stay
months there...
Cheers
Nelson
