     * (especially as Accurev uses the term "repository" to refer to the Accurev server) so an

     * {@link SCMSourceCategory#collectAndSimplify(Iterable)} will contain an {@link UncategorizedSCMSourceCategory} under
     * the {@code default} key that has a {@link #getDisplayName()} of {@code Depots / Repositories} (which may indeed
     * confuse the Accurev users who have not been exposed to Git, but as both are in use they should have
     * been prepared for the different terminology)
