Because this little script has got quite some popularity I have created a seperate svn repostitory for it, which will always contain the newest version. If you are using linux and have subversion installed you can check it out by entering the following on your commandline: :
$ svn co svn://svn.pureenergy.cc/php_classgraph
Unfortunatly the generator wasn't tested on a lot of code, because I do not have the time for this at the moment.
If you have any problems with it don't hesitate to drop me a line. I will try to look into it as soon as I got some spare time.
