+Pngcrush is an optimizer for PNG (Portable Network Graphics) files.
+It can be run from a commandline in an MSDOS window, or from a UNIX or
+LINUX commandline.  Its main purpose is to reduce the size of the PNG IDAT
+datastream by trying various compression levels and PNG filter methods.
+It also can be used to remove unwanted ancillary chunks, or to add
+certain chunks including gAMA, tRNS, iCCP, and textual chunks.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.  Line
+# up the first '|' above the ':' following the base package name, and the '|'
+# on the right side marks the last column you can put a character in.  You must
+# make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':'.
