Hi Neil,

I hadn't realised that you were embarking on an ambitious project from such
a low point on the learning curve. In order to find and use the new flight
plan stuff you need to download the latest data and source code from the cvs
repository. You then need to compile the source code. This is a complex
subject, but if you use Linux, then this procedure should be fairly familiar
to you, and if you are on Windows, then here's a step by step guide:

http://www.oflebbe.de/oflebbe/FlightGear/index.html

You will probably need to set aside several days to get to understand and
then get it all to work correctly. But you will find it very rewarding if
you do.

Of course all the new stuff won't work on ver 0.9.10, which is old, and very
out of date. Otherwise you will have to wait until there is a new release,
and that doesn't seem like any time soon, but we might be surprised.

I'm now in the process of implementing another new concept - the WAITUNTIL
token which when encountered in a flight plan will cause the AIShip to pause
until a specified time (gmt) is reached. That will probably be finished by
the end of this weekend.
