From 6cfadda161ce19e6c8076d0aa118f8f436805a6a Mon Sep 17 00:00:00 2001 From: David Kalnischkies Date: Sun, 12 Jul 2015 18:28:34 +0200 Subject: headers are for declarations only Housekeeping. This used to be embedded in apt-get directly, then moved to into our (then new) private lib and now header and code get a proper separation.
