+// AA - major version number
+// BB - minor version number
+// CC - bugfix version number
+// DD - alpha / beta (DD + 50) version number
+//
+// When DD is not 00, 1 is subtracted from AABBCC. For example:
+//
+// Version     AABBCCDD
+// 2.0.0       02000000
+// 2.1.0       02010000

+
+// Generally, we expect minor versions to be source code backwards-
