RPackages should (by design) correspond to a Monticello package, where Monticello is the code-package repository and versioning system
Metacello is a package management system that manages dependencies between different Monticello packages (providing the equivalent of the facilities such as maven, npm, apt-get)
Versionner helps you to generate Metacello configurations
The Configuration Browser allows you to browse the Metacello configurations from a given repository, and load them.
