 the tx value any more. It is in use in Freifunk Freiburg*
 
-emergency.sh
-============
-this repository also includes an emergency script which checks for a working batman-adv
-gateway connection. If no Gateway connection exists some countermeasures are started:
-
- - 3 min offline - call `wifi`
- - 5 min offline - restart fastd
- - 7 min offline - restart networking
-
-If no countermeasure works bringing the node online again, the router will be enforced
-to reboot after 10 minutes.
-
-*Note: this script may cause a problem for users, that use the node on purposes intended
-to work without functioning gateway connectivity, for example as a switch (disable
-the cronjob there).*

 Gluon versions
 ==============
-This branch of the skript contains the the ssid-changer version for the gluon 2016.1.x
-based on openwrt `chaos-calmer`. There is also a pre 2016.1 (barrier braker based)
-version in the branch `master`. It will probably not work in 2016.2 yet.
