Please add the following line to this comment block and the LocationProvider
comment block above:

// FYI: Used by an external project; please don't remove. Contact xxx at yy
// for more information.

Edit it so that future maintainers have contact information for you and can make
sure they don't unnecessarily break you by removing these two API integration
points.
