Welcome to FlightGear Deamon fgd
--------------------------------
Here the first Tools to play with FlightGear Deamon.
-This is yet alpha and the sources remain to be tidied up,
+This is yet alpha moving to beta and the sources remain to be tidied up,
and to get documented.
Nov 29 1999 -> Implementing scenario functions like virtual
Pilots
Nov 30 1999 -> ???
+ v0.1-beta : Jan 16 2000 -> Several libc5, glibc-2.0 and glibc-2.1
+ issues cleaned up
Future Plans:
Send comments/flames/BEER/whatever to delise@mail.isis.de
