Summary     : Automatic WiFi connection (re)establishment daemon
Description :
WiFiRoamd is a program that monitors your wireless device to keep it
connected to a good access point.  It will scan looking for a known AP, or
will try the AP with the strongest un-encrypted signal.  If a script is
found for the specific AP ESSID or MAC address is found, that script is
run.  Otherwise, a "default" script is run.

After that script is run, scripts in the "up.d" directory are run.  These
implement extra functionality such as DHCP, ESSID "pinning" (where it
explicitly does "iwconfig $DEVICE essid $ESSID", so that you don't
accidentally wander to another AP) and other local things such as
restarting OpenVPN, etc.
