This is extension is a standalone version of the tclkit [zlib] command/extension.

See http://wiki.tcl.tk/zlib for command syntax.

This package is a freely available open source package.  You can do
virtually anything you like with it, such as modifying it, redistributing
it, and selling it either in whole or in part.  See the file
"license.terms" for complete information. 

It was created by Pascal Scheffers <[email protected]> by bundling
zlib.c by Jean-Claude Wippler from the tclkit sources, zlib and
banging on sampleextension until it worked. Feel free to do with it as
you like, as long as you honor the original licenses and zlib. zlib.c
was placed in the public domain by JCW.

Have fun.

UNIX or Msys+Mingw simple build
===============================

The really simple way of building this package is

	$ cd zlib
	$ /path/to/my/tclsh build.tcl

This should auto detect the tclConfig.sh to be used for building the
extension. If that part fails, you can also specify the directory
which holds tclConfig.sh (for example /usr/local/lib)

	$ cd zlib
	$ /path/to/my/tclsh build.tcl /usr/local/lib

UNIX BUILD
==========

Before building the extension, libz(.a) needs to be available. Most
Unix systems have libz installed, so you can just run the configure
script and then run make. If you do not have libz installed (configure
will complain about it.), you should build the zlib copy provided with
this extension in the zlib directory.

For more information about the build process, see
the tcl/unix/README file in the Tcl src dist. The following minimal
example will install the extension in the /opt/tcl directory.

	$ cd zlib
	$ ./configure --prefix=/opt/tcl
	$ make
	$ make install

This example will build the zlib as well:

	$ cd zlib/zlib
	$ ./configure
	$ make
	$ cd ..
	$ ./configure --prefix=/opt/tcl
	$ make
	$ make install


WINDOWS BUILD
=============

The recommended method to build extensions under windows is to use the
Msys + Mingw build process. This provides a Unix-style build while
generating native Windows binaries. Using the Msys + Mingw build tools
means that you can use the same configure script as per the Unix build
to create a Makefile.

Building with VC++ has not been tested
