+/* The InterAspect package for GCC is a framework for building GCC plug-ins
+   that perform instrumentation.  InterAspect has two goals:
+     1: to serve as the interposition backend for a GCC
+        Aspect-Oriented Programming (AOP) utility;
+     2: to make it simple to write stand-alone plug-ins that implement
+        custom instrumentation.
+
+   For both of these goals, InterAspect provides functions to
+   interpose on a variety of program events.  The framework can insert
+   calls to "advice" functions at the points in the program where
+   these events occur (known as "join points").  Furthermore, inserted
+   calls can pass values from the running program to the advice
+   function. */
