CMS using CodeIgniter need help on the plugin manager

[eluser]anis2505[/eluser]
Hi to all,

As a final year student my project is to develop a new cms for the university websites.

So I started and now I'm 99% finshed on the system core.

My problem is how to make a plugin manager for the system?

I know there is many CMS out there based on CI so could you give an ideo how to bild this plugin manager (or extension manager name it whatever you want :-)).
Please I need help.

Regards
