png

I've read through man pngcrush and it seems that there is no way to crush a PNG file and save it over the original. I want to compress several folders worth of PNGs so it would be useful to do it all with one command!

Currently I am doing pngcrush -q -d . *.png then manually cut-pasting the files from the tmp directory to the original folder. So I guess using mv might be the best way to go? Any better ideas?
