-# checks for obsolete/local and upgradeable packages.
-#
-# packages for the obsolete/local check can be ignored, by
-# listing their full name in /etc/nagios/obsolete-packages-ignore
-# or by having a regex (starting a line with "/") that matches
-# the packagename in said file.
-#
-# Takes one optional argument, the location of the ignore file.
