+// into a platform specific implementation at compile time. This is
+// a fairly ugly process that requires lots of ifdef's based on the
+// particular implementation of shared libraries.
+//
+// Adding a new dynamic library implementation for a platform involves
+// two steps:
+//
+//     	1) Create a new implementation of the DynamicLib object (see
+//	   DlDynamicLib.C for an example).
+//
+//	2) Adding the appropriate ifdef construction step to this function.
