+// This file defines pass wrappers around LLVM analyses that don't make sense to
+// be passes. It provides a nice standard pass interface to these classes so
+// that they can be printed out by analyze.
+//
+// These classes are seperated out of analyze.cpp so that it is more clear which
+// code is the integral part of the analyze tool, and which part of the code is
+// just making it so more passes are available.
