       include-what-you-use - Analyze #includes in C and C++ source files

DESCRIPTION

       USAGE: include-what-you-use [-Xiwyu --iwyu_opt]... <clang opts> <source file> Here are the
       <iwyu_opts> you can specify (e.g. -Xiwyu --verbose=3):

       --check_also=<glob>: tells iwyu to print iwyu-violation info

              for all files matching the given glob  pattern  (in  addition  to  the  default  of
              reporting  for  the  input .cc file and its associated .h files).  This flag may be
              specified multiple times to specify multiple glob patterns.

       --cwd=<dir>: tells iwyu what the current working directory is.

       --help: prints this help and exits.

       --howtodebug[=<filename>]: with no arg, prints instructions on

              how to run iwyu under gdb for the input file, and exits.  With an arg, prints  only
              when input file matches the arg.

       --mapping_file=<filename>: gives iwyu a mapping file.

       --no_default_mappings: do not add iwyu's default mappings.

       --transitive_includes_only: do not suggest that a file add

              foo.h unless foo.h is already visible in the file's transitive includes.

       --verbose=<level>: the higher the level, the more output.
