-Sorry, no README yet.
+Sorry, no real README yet.
+
+Just a short intro:
+
+waproamd is to be used together with ifplugd.
+
+waproamd: when not associated waproamd does periodic scans and tries to associate to a sensible AP by running a script in /etc/waproamd/scripts
+
+aeswepd: A daemon for doing AES based WEP rekeying, is called by /etc/waproamd/scripts/default if /etc/waproamd/keys/foo.aes exists
+
+ifplugd: if an associating succeeded runs ifup for the device
+
+waproamd will not issue scans while associated. 
+
+The algorithm to select an AP if multiple are available is rather simple: Just take the first one having a script in /etc/waproamd/scripts.
+
+If a script named after the MAC address of the AP is available in /etc/waproamd/scripts/ it is run if an AP is selected. If not /etc/waproamd/scripts/default is run. Have a look on that script to see its arguments.
