+//  without it forcing a recompile on something ccache would otherwise not
+//  have to rebuild...this file's checksum changes every time you build it
+//  due to the __DATE__ and __TIME__ macros.
+
+// The makefile will rebuild this file everytime it relinks an executable
+//  so that we'll always have a unique build string.
+
+// APPNAME and APPREV need to be predefined in the build system.
