5#	The programs built by this makefile are described in the book,
6#	"PNG:  The Definitive Guide," by Greg Roelofs (O'Reilly and
7#	Associates, 1999).  Go buy a copy, eh?  Well, OK, it's not
8#	generally for sale anymore, but it's the thought that counts,
9#	right?  (Hint:  http://www.libpng.org/pub/png/book/ )
10#
11# Invoke this makefile from a DOS prompt window via:
12#
13#	%devstudio%\vc\bin\vcvars32.bat
14#	nmake -nologo -f Makefile.w32
15#
16# where %devstudio% is the installation directory for MSVC / DevStudio.  If
17# you get "environment out of space" errors, create a desktop shortcut with
18# "c:\windows\command.com /e:4096" as the program command line and set the
19# working directory to this directory.  Then double-click to open the new
20# DOS-prompt window with a bigger environment and retry the commands above.
21# 
22# This makefile assumes libpng and zlib have already been built or downloaded
23# and are in subdirectories at the same level as the current subdirectory
24# (as indicated by the PNGPATH and ZPATH macros below).  Edit as appropriate.
25#
26# Note that the names of the dynamic and static libpng and zlib libraries
27# used below may change in later releases of the libraries.  This makefile
28# builds statically linked executables, but that can be changed by uncom-
29# menting the appropriate PNGLIB and ZLIB lines.
