+// This file will select an implementation for a ThreadOps based on
+// what ThreadOps.h selects. This method is for selecting the 
+// source files, to improve portability. Currently, the project is
+// based on the autoconf tool-set, which doesn't support conditional
+// compilation well. Additionally, this should make the library 
+// easier to port since its working around conditional compilation
+// by using C++ features and people won't have to fiddle around with
+// their make tool as much to compile the source
