TERMUX_PKG_DESCRIPTION="Toolkit for manipulation of graphic images, including conversion of images between a variety of different formats"
# The netpbm releases are described at http://netpbm.sourceforge.net/release.html
# and are divided among (1) Development, (2) Advanced, (3) Stable and (4) Super Stable.
# Only Super Stable is distributed as a tar ball, but is outdated and does not compile with modern libpng.
# So use revisions from http://svn.code.sf.net/p/netpbm/code/advanced for packages.
