# azilink for OS X
# based on http://pastie.org/405289 but works with Tunnelblick only

# or building from source by hand, thankfully)
# Requires: 
# - azilink running on android phone (http://code.google.com/p/azilink/)
#   (run the app and check the box to start the service).
# - adb on system path (comes with the Android SDK; 
#   add its tools folder to your PATH in ~/.profile or 
#   place or symlink the sdk's tools/adb file in e.g. usr/local/bin or somewhere else on the PATH)
# - Tunnelblick, a nice OS X packaging of OpenVPN (http://code.google.com/p/tunnelblick/)
#   Install Tunnelblick to Applications. Tested with Tunnelblick 3.0b22
