+      For every symbol (type, function variable, or macro) that you use in
+      foo.cc, 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. The main goal of include-what-you-use is to remove
+      superfluous #includes. It does this both by figuring out what #includes
+      are not actually needed for this file (for both .cc and .h files), and
+      replacing #includes with forward-declares when possible.
