A <project> can be scoped by an organization or user handle. For
example, if an organiztion (rspec) has a project (rspec-core), then
the <project> would be `rspec/rspec-core`. If a user (justin) has a
project (my-project), then <project> would be `justin/my-project`.
If you leave off the organization or user handle, then it defaults
to the user (you).
