Does this plugin do…

I was told about your plugin & am hoping it will help me. I looked thru the information, but was still not entirely clear if it solves the issue that I am hoping for.

Is there a plugin that helps manage access to certain pages by users in the admin?

For example if I have a site that has 40 pages:
I may only want user X to access 3 specific pages in the admin.

Where as user Y can only access 5 other pages.

And user Z can access all the pages which a typical user account.

Does your plugin help with these types of advance user control from within the admin?
