Create an Android project from existing one

How can I create a new project from an existing project, using Androi开发者_Python百科d command line tools?

android update project ... ?

Why i want to implement this kind of process: I would like to create a batch file to generate a new project from an existing one, then build the apk from that newly created project, using Ant. This whole process needs to be working without Eclipse or any other IDE.

Thanks!
