New in 0.57
+* Converted to a simpler frame rate counting method.
+* Fixed the AOA reading on the HUD.
+* Removed gpc from the Lib section of distribution by request of the
+ gpc Author. The gpc license is unfortunately not compatible with
+ the GPL. I may look for an alternative library, or just require
+ that developers download this library separately.
+* First slew of changes from the MacOS porting effort contributed by
+ "Robert Puyol" <puyol@abvent.fr>.
* Support for an arbitrary number of serial ports + additional serial port
output tweaks.
+* Serial output tweaks to make things more robust and act more like a GPS.
* Portability enhancements for Borland, Solaris, and SGI.

fgCONTROLS becomes FGControls.
