671242f350d172e106580348e24bab66b0d7e6a5vboxsync# Associates, 1999). Go buy a copy, eh? Buy some for friends
671242f350d172e106580348e24bab66b0d7e6a5vboxsync# and family, too. (Not that this is a blatant plug or anything.)
671242f350d172e106580348e24bab66b0d7e6a5vboxsync# Invoke this makefile from a shell prompt in the usual way; for example:
671242f350d172e106580348e24bab66b0d7e6a5vboxsync# This makefile assumes libpng and zlib have already been built or downloaded
671242f350d172e106580348e24bab66b0d7e6a5vboxsync# and are both installed in /usr/local/{include,lib} (as indicated by the
671242f350d172e106580348e24bab66b0d7e6a5vboxsync# PNG* and Z* macros below). Edit as appropriate--choose only ONE each of
671242f350d172e106580348e24bab66b0d7e6a5vboxsync# the PNGINC, PNGLIB, ZINC and ZLIB lines.
671242f350d172e106580348e24bab66b0d7e6a5vboxsync# This makefile builds statically linked executables (against libpng and zlib,
671242f350d172e106580348e24bab66b0d7e6a5vboxsync# that is), but that can be changed by uncommenting the appropriate PNGLIB and
671242f350d172e106580348e24bab66b0d7e6a5vboxsync# ZLIB lines.
