# makefile for PNG (Portable Network Graphics) code.
# Users of this makefile must define the following:
#	ZSRCDIR - the zlib source directory
#	ZGENDIR - the zlib generated intermediate file directory
#	ZOBJDIR - the zlib object directory
#	PNGSRCDIR - the source directory
#	PNGGENDIR - the generated intermediate file directory
#	PNGOBJDIR - the object directory
#	SHARE_LIBPNG - 0 to compile libpng, 1 to share
#	LIBPNG_NAME - if SHARE_LIBPNG=1, the name of the shared library
#       PNG_CFLAGS

# This partial makefile compiles the png library for use in the Ghostscript
# PNG drivers.  You can get the source code for this library from:
#   http://www.libpng.org/pub/png/src/
#   ftp://swrinde.nde.swri.edu/pub/png/src/
#   ftp://ftp.uu.net/graphics/png/src/
#   http://libpng.sourceforge.net/
# Please see Ghostscript's `Make.htm' file for instructions about how to
# unpack these archives.
#
# When each version of Ghostscript is released, we copy the associated
# version of the png library to
#	ftp://ftp.cs.wisc.edu/ghost/3rdparty/
# for more convenient access.
#
# this makefile should work with libpng versions 0.90 and above
#
# NOTE: the archive for libpng 0.95 may be inconsistent: if you have
# compilation problems, use a newer version.
#
# Please see Ghostscript's Make.htm file for instructions about how to
# unpack these archives.
#
# The specification for the PNG file format is available from:
#   http://www.group42.com/png.htm
#   http://www.w3.org/pub/WWW/TR/WD-png

# (Rename directories.)
