[Pharo-users] Using Icerberg programmatically.

Hi All, the new Iceberg is really cool. I'm using it in Pharo 6.1. Is there some documentation or script examples on how to use Iceberg programmatically? I would like to write an script to pull changes to an existing repository, before doing some other stuff. I can do it with the UI, but I would like to automatize it. Any pointer is welcome. Thanks in advance. Arturo
