Looking at the PureMVC PHP project, I see why. We need a library file. Is there a utility similar to what the JavaScriptians use to put all the classes in a file, and remove extraneous spaces and returns (minify)?
So, clearly we will either need to figure out how to create a library file for inclusion in PHP projects, it's a great hinderance to have to handle it this way. That's not your fault of course, it's just the project owner hasn't gotten around to it. If you know of a good tool for doing this, please let me know.
Oh, I thought I wasn't supposed to include dependencies. Now I see what libs directory is for. PHP CLI has a built in whitespace/comment stripper. You concatenate the files by hand or with a tool and run: php -w source.php
I've repackaged the demo, now it includes minified PureMVC sources.
