Please help me with multi-applications management.

[eluser]BnoL[/eluser]
Hi all,

I’m currently managing multi applications with CI:

just like: application/prj1 , application/prj2 ...

and I have written some new classes (base on CI core classes) and put them in “libraries” folder of each application, ex: “application/prj1/libraries/MY_Controller.php” ...

But if I do so, I have to copy my classes to all of my prjs’ folders (prj2,prj3,...), and it’s not good for maintenancing or updating…

So I want to put them in a new place so that all prjs can use 1 “libraries”, “helpers”... folder, for example: “application/libraries”, “application/helpers”...

My question is: if I do so, what’s the best way to config the core to make it works?
or is there any better solutions ?

Thanks in advance and sry for my bad English
