-# Sample makefile for rpng-x / rpng2-x / wpng using gcc and make.
-# Greg Roelofs
-# Last modified:  2 June 2007
-#
-#	The programs built by this makefile are described in the book,
-#	"PNG:  The Definitive Guide," by Greg Roelofs (O'Reilly and
-#	Associates, 1999).  Go buy a copy, eh?  Well, OK, it's not
-#	generally for sale anymore, but it's the thought that counts,
-#	right?  (Hint:  http://www.libpng.org/pub/png/book/ )
-#
-# Invoke this makefile from a shell prompt in the usual way; for example:
-#
-#	make -f Makefile.unx
-#
-# This makefile assumes libpng and zlib have already been built or downloaded
-# and are installed in /usr/local/{include,lib} or as otherwise indicated by
-# the PNG* and Z* macros below.  Edit as appropriate--choose only ONE each of
-# the PNGINC, PNGLIBd, PNGLIBs, ZINC, ZLIBd and ZLIBs lines.
-#
-# This makefile builds both dynamically and statically linked executables
-# (against libpng and zlib, that is), but that can be changed by modifying
-# the "EXES =" line.  (You need only one set, but for testing it can be handy
-# to have both.)
