+&# Usage:
+&#   &:include subdirmk/clean.sd.mk
+&# (probably in Perdir.sd.mk)
+&#
+&# Provides a per-directory `clean' target, which deletes all the files
+&# in &CLEAN.  &OBJECTS, &DEPFILES and &TARGETS are automatically deleted.
+&#
+&# If you want to delete a directory, extend the target with
+&#   &/clean::
+&#	$(RM) -r somethingn
+&# ($(RM) conventionally contains `-f'.)
