+openwrt-network
+================
+
+network (and dhcp) config of your openwrt system.
+compare: [http://wiki.openwrt.org/doc/uci/network] and 
+[http://wiki.openwrt.org/doc/uci/dhcp]
+
+Role Variables
+--------------
+
+a bunch of per interface settings are all nested in a dict
+`network` and another `dhcp` one. the layout is a bit weird because
+i use with_subelements. look at the defaults and tasks directory.
+if you have a suggestion for how to do it more effectively without
+duplication, let me know!
+
+you may want to consider `hash_behaviour=merge` in your ansible.cfg

+Dependencies

+
+Example Playbook
+----------------
+
+[https://github.com/lefant/ansible-openwrt/blob/master/openwrt.yml]
+
+Requirements
+------------
+
+must be kept minimal as this is supposed to run on openwrt embedded
+systems. in particular we try get by with plain POSIX shell, using
+neither python nor bash in any way. lua could be an option as that
+seems to be the openwrt scripting language of choice.
