Using quilt with debhelper
--------------------------
If you use the dh command provided by debhelper 7, you can simply
call it with "dh --with quilt" and dh_quilt_patch/dh_quilt_unpatch
will be called at the right time.

Otherwise you can manually call dh_quilt_patch / dh_quilt_unpatch
at the right place, see their respective manpages for examples.
