will halt with the first failed parse.
.El
.Pp
+The options
+.Fl fhklw
+are also supported and are documented in man(1).
In
.Fl f
and
mode,
.Nm
also supports the options
-.Fl CMmOSsw
+.Fl CMmOSs
described in the
.Xr apropos 1
manual.
-.Ss Input Formats
-The
-.Nm
-utility accepts
-.Xr mdoc 7
-and
-.Xr man 7
-input with
-.Fl m Ns Cm doc
-and
-.Fl m Ns Cm an ,
-respectively.
-The
-.Xr mdoc 7
-format is
-.Em strongly
-recommended;
-.Xr man 7
-should only be used for legacy manuals.
-.Pp
-A third option,
-.Fl m Ns Cm andoc ,
-which is also the default, determines encoding on-the-fly: if the first
-non-comment macro is
-.Sq \&Dd
-or
-.Sq \&Dt ,
-the
-.Xr mdoc 7
-parser is used; otherwise, the
-.Xr man 7
-parser is used.
-.Pp
-If multiple
-files are specified with
-.Fl m Ns Cm andoc ,
-each has its file-type determined this way.
-If multiple files are
-specified and
-.Fl m Ns Cm doc
-or
-.Fl m Ns Cm an
-is specified, then this format is used exclusively.
+The options
+.Fl fkl
+are mutually exclusive and override each other.
.Ss Output Formats
The
.Nm
utility accepts the following
.Fl T
arguments, which correspond to output modes:
-.Bl -tag -width "-T locale"
+.Bl -tag -width "-T markdown"
.It Fl T Cm ascii
Produce 7-bit ASCII output.

.Sx Man Output .
+.It Fl T Cm markdown

.It Fl T Cm pdf

is used as a template for linked header files (usually via the
-.Sq \&In
+.Ic \&In
macro).
Instances of
.Sq \&%I
for example,
.Ar ../html%S/%N.%S.html ,
is used as a template for linked manuals (usually via the
-.Sq \&Xr

macro).
Instances of

.Xr man 7 ,
the input is copied to the output, expanding any
.Xr roff 7
-.Sq so
+.Ic so
requests.
The parser is also run, and as usual, the
.Fl W
level controls which
.Sx DIAGNOSTICS
are displayed before copying the input to the output.
+.Ss Markdown Output
+Translate
+.Xr mdoc 7
+input to the
+.Sy markdown
+format conforming to
+.Lk http://daringfireball.net/projects/markdown/syntax.text\
+ "John Gruber's 2004 specification" .
+The output also almost conforms to the
+.Lk http://commonmark.org/ CommonMark
+specification.
+.Pp
+The character set used for the markdown output is ASCII.
+Non-ASCII characters are encoded as HTML entities.
+Since that is not possible in literal font contexts, because these
+are rendered as code spans and code blocks in the markdown output,
+non-ASCII characters are transliterated to ASCII approximations in
+these contexts.
+.Pp
+Markdown is a very weak markup language, so all semantic markup is
+lost, and even part of the presentational markup may be lost.
+Do not use this as an intermediate step in converting to HTML;
+instead, use
+.Fl T Cm html
+directly.
+.Pp
+The
+.Xr man 7 ,
+.Xr tbl 7 ,
+and
+.Xr eqn 7
+input languages are not supported by
+.Fl T Cm markdown
+output mode.
.Ss PDF Output

.El
.Sh EXIT STATUS
The
.Ic \&Nd
macro lacks the required argument.
The title line of the manual will end after the dash.
+.It Sy "description line outside NAME section"
+.Pq mdoc
+An
+.Ic \&Nd
+macro appears outside the NAME section.
+The arguments are printed anyway and the following text is used for
+.Xr apropos 1 ,
+but none of that behaviour is portable.
.It Sy "sections out of conventional order"
.Pq mdoc
A standard section occurs after another section it usually precedes.
