SirGecko just released the first version of their PHP Autoloader. This auto loader is great because I can use it in any of my PHP projects and no longer have to keep track of and/or require() my objects. I simply drop this auto loader into my project, setup the directories my classes are in in the autoloader.php file, and include it in the project bootstrap file. Blam! No more requiring class files. Surprisingly my development time has actually increased quite a bit through the usage of this library. Be sure to check it out and use it on your projects.
