+ssid-changer
+============
+
+Script to change the SSID when ther is no suffic sufficient connection in the mesh.
+
+It is quite basic, just check the TQ of the Connection and decide if a change of the SSID is necessary.
+
+Add the following lines to the modules file in your gluon directory:
+
+PACKAGES_SSIDCHANGER_REPO=https://github.com/ffac/gluon-ssid-changer.git
+PACKAGES_SSIDCHANGER_COMMIT=tbd
+
+With this done you can add the package gluon-ssid-changer to your site.mk
