hi there - welcome to the pdf generation class..
to install, put all the files in the indicated directories.
make sure that the web server has write permission to the 'fonts' sub-directory, the first time it uses each font it creates a serialized afm file which is much faster on subsequent uses.
then view the readme.php file through the web browser, this should produce a pdf document (streaming) which contains the documentation.
and problems, write to us as firstname.lastname@example.org, or try downloading the zip file from the site:
there pdf documentation is pre-generated there, and there is a live demo to play with too.
