+# 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 ':'.

+optipng: optipng (lossless PNG optimizer)
+optipng:
+optipng: OptiPNG is a PNG optimizer that recompresses image files to a smaller
+optipng: size, without losing any information. This program also converts
+optipng: external formats (BMP, GIF, PNM and TIFF) to optimized PNG, and
+optipng: performs PNG integrity checks and corrections.
