30 For every symbol (type, function variable, or macro) that you use in
31 foo.cc, either foo.cc or foo.h should #include a .h file that exports the
32 declaration of that symbol. The main goal of include-what-you-use is to
33 remove superfluous #includes, both by figuring out what #includes are not
34 actually needed for this file (for both .cc and .h files), and by
35 replacing #includes with forward-declares when possible.
