Installation of PhpWF is very simple: copy the file phpwfwd.inc (wich is in the lib directory
of the tarball) in some dir of your web server enabled to execute php scripts. After this you can include phpwfwd.inc in
the site scripts. Instead, if you want to try the examples, extract the entire tarball into a dir of your php-enabled web server.
Actually the software is tested under linux with apache web server and php4 or php5, but shoud work
on any operating system and web server with php (4 or 5).
