The pngcrush-1.5.10 ebuild does not install the pngcrush manpage. I do not know if any other manpages should be associated with this package.

pngcrush does not have any man page as far as I can tell. Please point to the man page file if I am mistaken. It does however, have two text files, Install.txt and Readme.txt, which are now installed if the doc USE flag is on. Thanks for reporting!
