Package: pngcrush
Version: 1.8.13-2~exp1
The documentation leaves a small but rather curious gap: neither the manual
pages (`man pngcrush`) nor the built-in help (`pngcrush --help`) explain what
the mysterious arguments `alla` and `allb` mean when passed to the `-rem`
option.
Examples:
pngcrush -rem alla input.png output.png
pngcrush -rem allb input.png output.png
Currently, the only way to discover their meaning seems to be consulting the
Internet, or worse, reading the source code. It would be wonderful if users
could instead learn this from the locally installed documentation, as with
other options.
I do know an *Alla*, but I'm quite sure she wouldn't appreciate being removed
from a PNG file. As for *Allb*, I've never met them, except, perhaps, an
overweight Al(ex) heavy on lb . :-)
Gratefully,
Peter
