# 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.
