.Nm mdocml
.Op Fl v

.Op Ar infile
.\"
.Sh DESCRIPTION
The
.Nm
utility interfaces the
.Xr mdoc 3
library to validate and parse mdoc-macro documents.  Arguments follow:
.Bl -tag -width "\-Werr... "
.It Fl W Ns Ar err...
Print warning messages.  May be set to 
.Fl W Ns Ar all
for all warnings, 
.Ar compat
for groff/troff-compatibility warnings, or
.Ar syntax
for syntax warnings.  If
.Fl W Ns Ar error 
is specified, warnings are considered errors and cause utility
termination.  Multiple 
.Fl W
arguments may be comma-separated, such as
.Fl W Ns Ar error,all .
.It Fl v
Print verbose parsing output.
.It Ar infile
Read input from
.Ar infile ,
which may be 
.Dq \-
for stdin.
.El
.Pp
Parsing and validation rules are drawn entirely from the 
.Xr mdoc 7
and
.Xr mdoc.samples 7 
manuals.
.Pp
By default,
.Nm
reads from stdin, writes messages to stdout, and writes errors and
warnings to stderr.

.Sh CAVEATS
The most glaring short-coming of 
.Nm
is that it doesn't yet support the 
.Sq \&Xc
and
.Sq \&Xo
macros when used to extend the line arguments to
.Sq \&It ;
in effect, trampling the body section.  We note that this is explicitly
discouraged in
.Xr mdoc.samples 7 ,
but in practice used quite often.
