Use case - Easy project setup

• With Maven installed it should be a simple command that allows you to
  checkout the sources for a project.

• Maybe this could be generalized so that if you reference a remote
  descriptor it will download the project. Something like

$ maven --project http://www.realityforge.org/daedalus-project.xml

would result in download of project either from remote location or
maybe from scm declarations in project descriptor.

As part of this remote downloading though the user may be asked for
input of particular configuration data (ie username etc). (PD)
