Application模块在zend骨架中的作用是什么?

I have a project in hand that is going to have some five for more modules. Each module is going to be used for one the departments in our organization. They may interact with each other, but not necessary. Say finance, inventory, staff, etc. So application is going to be sort of Business suite.

Question: In zend framework 2, the skeleton comes with an Application module. Shall I look at it a global module that hold some common sections. like Applications layout wrapper for common layouts, for ACL controller and Auth controller, etc.

Is this some how the role for Application module? I appreciate any feed back. Thanks
