.Sh SYNOPSIS
.Nm mdocml
.Op Fl vW
.Op Fl f Ar filter
.Op Fl o Ar outfile

.\"
.Sh DESCRIPTION
The
.Nm
utility parses
.Xr mdoc
formatted manual source and passes results into the output filter
dictated by 
.Fl f Ar filter .
The only current output filter is
.Ar validate ,
the default.  The arguments are as follows:
.Bl -tag -width "\-o outfile,"
.It Sq Fl o Ar outfile ,
Place output in 
.Ar outfile ,
which may be
.Qq \-
for standard output.  The default is standard output.
.It Ar infile
Read input from
.Ar infile ,
which may be 
.Qq \-
for standard input.  The default is standard input.
.It Fl v 
Print messages (output depends on filter).
.It Fl W
Print warnings (output depends on filter).
.El
.Ss Validate Filter
The validate filter, specified by
.Fl f Ar validate ,
is the default filter.  It produces no output, so specifying
.Fl o Ar outfile
results in an empty file.

.Sh CAVEATS
Most caveats of
.Nm
stem from ambiguities in 
.Xr mdoc 7
or the necessary limitations of converting an ad hoc language into
structured ones:
.Bl -enum -compact -offset indent
.It 
The engine doesn't understand
.Sq \&Xo
and
.Sq \&Xc
troff macros.
.It 
All macro arguments may be quoted, instead of only some.
.It 
Blank lines raise warnings.
.It 
If terminating punctuation is found, then 
.Em all
remaining tokens are flushed after line scope is closed, not just the
last one.
