+* April 20, 2002
+
+* Created a src/libs subdirectory for several packages that need to be

+ coordinates. You can skip any of these you like to save on space.
+* Added support for new file features in the binary -> ascii scenery file
+ decoder.
+* Various code clean ups.

+* Removed all references to SGValue from the property manager. Added
