The code for the actual arrow is by James N. Whitehead II. See below for copyright notice
The code for distance calculation and minimap icons management is from Astrolabe by James Carrothers. See below for copyright notice
My contribute was mostly packaging them with a (hopefully) nice interface
LibArrow allows you to implement your own arrow without hijacking tomtom's one
Calling LibArrow-1.0 newArrow method will give you a simple arrow object you can manipulate in a number of ways (see API page).
You can even add a minimap icon for the same location with a simple call to an arrow method
