+
+# 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.
