In a new post to his blog Phil Sturgeon has posted about a patch he's created to give the pre-release CodeIgniter 2.0 version the ability to do some Modular Separation.
The fix was worked out a few hours after CodeIgniter 2.0 was released but I was hoping wiredesignz would incorporate and re-post. Sadly the man has other commitments to attend to, so I have released the patched version.
The patch includes two files - custom libraries to extend from for loading and routing in your CodeIgniter 2.0 application. For a better understanding of what this patch gives you, check out this thread on the CodeIgniter forums.
