+%description
+"Include what you use" means this: for every symbol (type, function, variable,
+or macro) that you use in foo.cc (or foo.cpp), either foo.cc or foo.h
+should #include a .h file that exports the declaration of that symbol. The
+include-what-you-use tool is a program that can be built with the clang
+libraries in order to analyze #includes of source files to find
+include-what-you-use violations, and suggest fixes for them.
