 /// \file
 ///  This file describes a subset of C++ as a protobuf. It is used to
 ///  more easily find interesting inputs for fuzzing Clang. This subset
-///  extends the one defined in cxx_proto.proto by adding the option that
-///  a VarRef can use the for loop's counter variable.
+///  differs from the one defined in cxx_proto.proto by eliminating while
+///  loops and Lvalues. The goal is that the C++ code generated will be
+///  more likely to stress the LLVM loop vectorizer.
