/**
Command line binary to pull core SilverStripe modules into a new project
This is an attempt to solve a problem introduced by the move to git, namely that new developers
who checkout the silverstripe-installer repo now don't get a "read to go" set of code, and they
shouldn't need to know how to use git or what modules need pulling in to get a base SilverStripe
install up and running.
Currently it doesn't attempt to solve the more general problem of updating or installing new modules
in an existing project - that's likely to be handled by some of this code + a re-architecture of sake
so that we can let developers add code to handle particulars of the process in an environment-aware manner
