+</PRE>
+This class expects to be run in a directory which contains the subdirectory
+structure shown below (where example aircraft X-15 is shown):
+
+<PRE>
+aircraft/
+ X-15/
+ X-15.dat reset00 reset01 reset02 ...
+ CDRAG/
+ a0 a M De
+ CSIDE/
+ b r Dr Da
+ CLIFT/
+ a0 a M adt De
+ CROLL/
+ b p r Da Dr
+ CPITCH/
+ a0 a adt q M De
+ CYAW/
+ b p r Dr Da
+ F-16/
+ F-16.dat reset00 reset01 ...
+ CDRAG/
+ a0 a M De
+ ...
+</PRE>
+
+The General Idea
+
+The file structure is arranged so that various modeled aircraft are stored in
+their own subdirectory. Each aircraft subdirectory is named after the aircraft.
+There should be a file present in the specific aircraft subdirectory (e.g.
+aircraft/X-15) with the same name as the directory with a .dat appended. This
+file contains mass properties information, name of aircraft, etc. for the
+aircraft. In that same directory are reset files numbered starting from 0 (two
+digit numbers), e.g. reset03. Within each reset file are values for important
+state variables for specific flight conditions (altitude, airspeed, etc.). Also
+within this directory are the directories containing lookup tables for the
+stability derivatives for the aircraft.
