+# 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 ':'.

+libpng: libpng (Portable Network Graphics library)
+libpng:
+libpng: PNG (Portable Network Graphics) is an extensible file format for the
+libpng: lossless, portable, well-compressed storage of raster images.  PNG
+libpng: provides a patent-free replacement for GIF and can also replace many
+libpng: common uses of TIFF.  Indexed-color, grayscale, and truecolor images
+libpng: are supported, plus an optional alpha channel.  Sample depths range
+libpng: from 1 to 16 bits.
