This script (still) naïvely assumes that you are using a Wi-Fi network and that you normally don’t have any DNS servers manually set.
There are four command available:
tunlr— toggle Tunlr on and off
tunlr on— explicitly set the Tunlr servers
tunlr off— explicitly unset the Tunlr servers
tunlr status— check what the current DNS settings are
Tunlr lets you stream content from sites like Netflix, Hulu, MTV, CBS, ABC, Pandora and more to your Mac or PC. Want to watch Netflix or HuluPlus on your iPad, AppleTV or XBox 360 even though you’re not in the U.S.? Tunlr lets you do this.
