.SH NAME
include-what-you-use \- Analyze #includes in C and C++ source files
.SH DESCRIPTION
USAGE: include\-what\-you\-use [\-Xiwyu \fB\-\-iwyu_opt]\fR... <clang opts> <source file>
Here are the <iwyu_opts> you can specify (e.g. \fB\-Xiwyu\fR \fB\-\-verbose\fR=\fI\,3\/\fR):
.HP
\fB\-\-check_also=\fR<glob>: tells iwyu to print iwyu\-violation info
.IP
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.
.HP
\fB\-\-cwd=\fR<dir>: tells iwyu what the current working directory is.
.HP
\fB\-\-help\fR: prints this help and exits.
.HP
\fB\-\-howtodebug[=\fR<filename>]: with no arg, prints instructions on
.IP
how to run iwyu under gdb for the input file, and exits.
With an arg, prints only when input file matches the arg.
.HP
\fB\-\-mapping_file=\fR<filename>: gives iwyu a mapping file.
.HP
\fB\-\-no_default_mappings\fR: do not add iwyu's default mappings.
.HP
\fB\-\-transitive_includes_only\fR: do not suggest that a file add
.IP
foo.h unless foo.h is already visible in the file's
transitive includes.
.HP
\fB\-\-prefix_header_includes=\fR<value>: tells iwyu what to do with
.IP
in\-source includes and forward declarations involving
prefix headers.  Prefix header is a file included via
command\-line option \fB\-include\fR.  If prefix header makes
include or forward declaration obsolete, presence of such
include can be controlled with the following values
.TP
add:
new lines are added
.TP
keep:
new lines aren't added, existing are kept intact
.IP
remove: new lines aren't added, existing are removed
.IP
Default value is 'add'.
.HP
\fB\-\-verbose=\fR<level>: the higher the level, the more output.
