t/99cvs_clone_delete_order.t

=head1 DESCRIPTION

Test that VCP::Source::cvs emits clone records in the correct order
when cloning a delete.  This is to address an issue that is reported
by VCP::Dest::cvs of "all revision(s) already integrated" which occurs
because VCP::Source::cvs clones a delete before it clones an edit.
