Aspen:Automated Installation
From Aspen Documentation
By default, Aspen provides a default installation process that's used for installing Aspen. You may modify this process by creating a copy of the Install module and editing the code as you wish.
The core Install process functionality is kept in the system folder solely so that you can extend it to meet your needs.
You can change the entire process from beginning to end, but if you intend on supporting single module installation processes, please leave install_module and uninstall_module functions left intact.
