Merge pull request #8 from sileht/master

I'm going to merge this. i've checked it out and tried it in a few places and everything seems in order. I'd also like to use the augeas changes, too but that commit hasn't been included in this request.
Merge branch 'master' into shorewall-conf-augeas

Conflicts:
