NAME

       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.
