include-what-you-use

"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 program is a tool 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 declarations when possible.
