+Installing libpng version 1.2.5 - October 3, 2002
+
+Before installing libpng, you must first install zlib. zlib
+can usually be found wherever you got libpng. zlib can be
+placed in another directory, at the same level as libpng.
+Note that your system might already have a preinstalled
+zlib, but you will still need to have access to the
+zlib.h and zconf.h include files that correspond to the
+version of zlib that's installed.
+
+You can rename the directories that you downloaded (they
+might be called "libpng-1.2.5" or "lpng109" and "zlib-1.1.4"
+or "zlib114") so that you have directories called "zlib" and "libpng".
+
+Your directory structure should look like this:
+
+ .. (the parent directory)
+ libpng (this directory)
+ INSTALL (this file)
+ README
+ *.h
+ *.c
+ contrib
+ gregbook
+ msvctest
+ pngminus
+ pngsuite
+ visupng
+ projects
+ beos
+ borland
+ msvc
+ netware.txt
+ wince.txt
+ scripts
+ makefile.*
+ libpng*.in
+ pngtest.png
+ etc.
+ zlib
+ README
+ *.h
+ *.c
+ contrib
+ etc.
+
+If the line endings in the files look funny, you may wish to get the other
+distribution of libpng. It is available in both tar.gz (UNIX style line
+endings) and zip (DOS style line endings) formats.
+
+If you are building libpng with MSVC, you can enter the libpng\msvc directory
+and follow the instructions in msvc\README.txt.
+
+You can build libpng for WindowsCE by entering the downloading and installing
+the libpng\wince directory as instructed in the projects\wince.txt file, and
+then following the instructions in the README* files. Similarly, you can
+build libpng for Netware as instructed in projects\netware.txt.
+
+Else enter the zlib directory and follow the instructions in zlib/README,
+then come back here and choose the appropriate makefile.sys in the scripts
+directory.
+

+ descrip.mms => VMS makefile for MMS or MMK
+ pngdef.pas => Defines for a png32bd.dll with Borland C++ 4.5
+ SCOPTIONS.ppc => Used with smakefile.ppc
+
+Copy the file (or files) that you need from the
+scripts directory into this directory, for example
+
+ MSDOS example: copy scripts\makefile.msc makefile
+ UNIX example: cp scripts/makefile.std makefile
+
+Read the makefile to see if you need to change any source or
+target directories to match your preferences.
+
+Then read pngconf.h to see if you want to make any configuration
+changes.
+
+Then just run "make test" which will create the libpng library in
+this directory and run a quick test that reads the "pngtest.png"
+file and writes a "pngout.png" file that should be identical to it.
+Look for "9782 zero samples" in the output of the test. For more
+confidence, you can run another test by typing "pngtest pngnow.png"
+and looking for "289 zero samples" in the output. Also, you can
+run "pngtest -m *.png" in the "contrib/pngsuite" directory and compare
+your output with the result shown in contrib/pngsuite/README.
+
+Most of the makefiles will allow you to run "make install" to
+put the library in its final resting place (if you want to
+do that, run "make install" in the zlib directory first if necessary).
+Some also allow you to run "make test-installed" after you have
+run "make install".
+
+Further information can be found in the README and libpng.txt
+files, in the individual makefiles, in png.h, in the README files in
+subdirectories of the LIB directory, and the manual pages libpng.3 and png.5.
