+// These macros indicate current version of XML resources (this information is
+// encoded in root node of XRC file as "version" property).
+//
+// Rules for increasing version number:
+//   - change it only if you made incompatible change to the format. Addition of new
+//     attribute to control handler is _not_ incompatible change, because older
+//     versions of the library may ignore it.
+//   - if you change version number, follow these steps:
+//       - set major, minor and release numbers to respective version numbers of
+//         the wxWindows library (see wx/version.h)
+//       - reset revision to 0 unless the first three are same as before, in which
+//         case you should increase revision by one
