+// PURPOSE: This module deals with:
+// - code replacement: intercepting calls to client functions, and
+//   pointing them to a different piece of code.
+// - loading notification: telling the core where certain client-space
+//   functions are when they get loaded.
+// - function wrapping: add calls to code before and after client
+//   functions execute, for inspection and/or modification.
