Imports a project from one or more Arch repositories. It will follow branches
and repositories within the namespaces defined by the <archive/branch>
-parameters suppplied. If it cannot find the remote branch a merge comes from
+parameters supplied. If it cannot find the remote branch a merge comes from
it will just import it as a regular commit. If it can find it, it will mark it
as a merge whenever possible.
