A tool for use with clang to analyze #includes in C and C++ source files
copied from cf-staging / 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. (Similarly, for footest.cc, either footest.cc or foo.h should do the including.) Obviously symbols defined in foo.cc itself are excluded from this requirement.
