[Pharo-project] Loading dependencies

Hi, At the moment I'm creating an analysis tool for Git repositories. I'm versioning my source code on Smalltalkhub, so that I can easily load my code in a fresh image, when needed. My project depends on several external packages such as the Filesystem-Git, Fuel, and the last version of Filesystem. I was wondering if it's possible to add such dependencies programmatically so that once I load my project from Monticello dependencies are added as well. I heard that Metacello is probably suitable to handle dependencies, but it would be glad to hear an opinion from you. Thanks in advance, Roberto
