-clang_linking - Build scripts that build the *_linking examples with clang.
-                Clang does not require changes to the source in either case.
-                The build lines require some modification on Windows.
-                On Linux clang can be directly swapped out for gcc.

+clang - Build scripts that build the concrete examples with clang instead of
+        cl or gcc. In each case clang can build the same source. In some cases
+        clang on windows can even build the linux source. The build lines for
+        clang that replace cl require some modification. The build lines for
+        clang that replace gcc have the exact same flags and inputs.
 
 xlist - My prefered solution to the problem posed in the investigation which
-        relies only on run-time linking. It uses an xlist to manage the
-        maintenance burden of run-time linking, and a basic outline of the
-        abstracted form of each layer.
