I've been curious about the geographic location functions, ever since
the pre-X days.  Back then, the location was stored in PRAM, read/
written by users with the "Map" control panel, and read/written by
developers with the "ReadLocation" and "WriteLocation" API.  What is
the modern equivalent?

(I'm stuck on Tiger and I'm using Apple's developer docs on the web.)
Looking at the Carbon Memory Managment Utility Reference,
"ReadLocation" is still usable, but "WriteLocation" has been
depreciated since Mac OS X 10.0 (i.e. killed since the X series), with
the very concept of changing this information banned.  This is hope in
the Carbon Date/Time/Measurement Utilities Reference, that claims that
geographic location can be set with the assistance of the
Authorization APIs.

Of course, reading up on the Authorization API only tells how to use
the APIs in general, it does _not_ give the specifics needed:

1. The appropriate rights IDs
2. Where the data is stored/accessed
3. What format the data is in
([2] and [3] don't need much explanation if you're supposed to
authorize somehow, then use the existing "WriteLocation" API.)
4. Which versions of Mac OS X is this technique valid

Can anyone help me here?  Or is there no answer, and a bug needs to be
filed?  At least some answer can help someone else in the future when
Google-ing for a solution.
