About
This will...
Set up HE's tunnel broker service.
Automatically finds your wan ip at boot using whatismyip.com
Automatically updates HE's endpoint on boot
Generates a radvd.conf on boot, and applies it automatically
Generates a executable file that can be used with cron to keep HE's endpoint up-to-date if you have a dynamic IP
My setup for reference.
