// This tool is used to move class/function definitions from the given source
// files (old.h/cc) to new files (new.h/cc).
// The goal of this tool is to make the new/old files as compilable as possible.
//
// When moving a symbol,all used helper declarations (e.g. static
// functions/variables definitions in global/named namespace,
// functions/variables/classes definitions in anonymous namespace) used by the
// moved symbol in old.cc are moved to the new.cc. In addition, all
// using-declarations in old.cc are also moved to new.cc; forward class
// declarations in old.h are also moved to new.h.
//
// The remaining helper declarations which are unused by non-moved symbols in
// old.cc will be removed.
//
// Note: When all declarations in old header are being moved, all code in
// old.h/cc will be moved, which means old.h/cc are empty. This ignores symbols
// that are not supported (e.g. typedef and enum) so that we always move old
// files to new files when all symbols produced from dump_decls are moved.
