Revision 1.6 1999/08/08 15:12:33 curt Revision 1.7 1999/08/17 19:18:16 curt
Updates from Tony. Updates from Tony.
Revision 1.1.1.1 1999/04/05 21:32:45 curt
Start of 0.6.x branch.
Revision 1.6 1998/10/17 01:34:16 curt
C++ ifying ...
Revision 1.5 1998/09/29 02:03:00 curt
Added a brake + autopilot mods.
Revision 1.4 1998/08/06 12:46:40 curt
Header change.
Revision 1.3 1998/02/03 23:20:18 curt
Lots of little tweaks to fix various consistency problems discovered by
Solaris' CC. Fixed a bug in fg_debug.c with how the fgPrintf() wrapper
passed arguments along to the real printf(). Also incorporated HUD changes
by Michele America.
Revision 1.2 1998/01/19 18:40:29 curt
Tons of little changes to clean up the code and to remove fatal errors
when building with the c++ compiler.
Revision 1.1 1997/05/29 00:10:02 curt
Initial Flight Gear revision.
