+Pngcrush is an optimizer for PNG (Portable Network Graphics) files. Its
+main purpose is to reduce the size of the PNG IDAT datastream by trying
+various compression levels an 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.
+
+Note
+-------
+This package builds the "nolib" version of pngcrush which assumes you
+have zlib and libpng installed (both are stock Slackware packages).

+# 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
