# 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 ':'.

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