+# Parsen van nagios config uit Genesis
+# by maarten@wirelessleiden.nl
+#
+# v0.5 - added args support for location output and genesis and added count to parser
+# v0.4 - handeling proxies
+# v0.3 - added hostgroups on postcode
+# v0.2 - append host ext info and xy for statusmap
+# v0.1 - loops trough all nodes and interfaces
+#
+# Inspired by:
+# - configcleaner.pl by Rick van der Zwet (rick@wirelessleiden.nl)
+# - conf2inc.pl
+
+#maak een mooi systeem met hash aanroepen om snel gegevens te verwerken
