Subject: [PATCH] wireless-regdb: fix Makefile to prevent unintended rebuilds
Date: Fri, 09 Jan 2009 13:24:05 -0500	[thread overview]
Message-ID: <20090109182405.31872.62007.stgit@dv.roinet.com> (raw)

Rules depending on key.priv.pem should only be available if that file is
already present.  They should not trigger automatic generation of
key.priv.pem.

"make clean" should not remove files that can only be generated by the
maintainer.  Use "make maintainer-clean" for that.

"make clean" should remove *.pyc files.
