%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 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.

# IWYU needs to find Clang's builtin headers. It looks for them relative to the
# binary (https://clang.llvm.org/docs/LibTooling.html#builtin-includes), but
# since it isn't installed into /usr/bin, it fails to find them. So we pass
# the directory manually to the executable, and because the test driver doesn't
# allow us to specify additional flags, we build a stub.
# Note that this isn't a problem for the installed package, because it will be
# in the same directory as the Clang binary.
