Auto Uploading and Installing Packages in AEM

Hi,

In our deployment scenario, the authoring and publishing server would be on different servers. The authoring team will create the content and publish it.
This published content will be ftped securely to a share.
We need to create a job, which will retrieve this published content zip and upload it in package manager and post uploading, install it.
Does AEM provides some commands to do this?
We are thinking to create a batch file or a dot net application (.exe) to acheive this, but need info on some AEM APIs which will help us do this.
 

Regards,
Aditya Nayak
