I'm not sure if anyone else would find this useful, but I threw together a simple script the other day for speeding up the process of configuring and managing my VPN connections on my desktop (Linux Mint). Note that this is far from comprehensive--I made it with my use cases in mind.
~$ airvpn setup pavonis --connect
Would prompt you for your username and password, generate the configuration, save it and set the appropriate permissions, then start the openvpn daemon. There are a few other useful commands as well.
