I was recently contacted about availability problems with the code for pngtools. Frankly, I’m mildly surprised anyone still uses this code, but I am happy for them to do so.

At the moment, the only command that is implemented is pnginfo, which is pretty much there (apart from the command line options, which are rarely used).
