.Sh DESCRIPTION
The
.Nm
utility formats
.Ux
manual pages for display.
+.Pp
+By default,
+.Nm
+reads
+.Xr mdoc 7
+or
+.Xr man 7
+text from stdin, implying
+.Fl m Ns Cm andoc ,
+and produces
+.Fl T Ns Cm ascii
+output.
+.Pp
The arguments are as follows:
.Bl -tag -width Ds
+.Sm off
+.It Fl I Cm os Li = Ar name
+.Sm on
+Override the default operating system
+.Ar name
+for the
+.Xr mdoc 7
+.Sq \&Os
+macro.
.It Fl m Ns Ar format
Input format.

.Nm
will halt with the first failed parse.
.El
-.Pp
-By default,
-.Nm
-reads
-.Xr mdoc 7
-or
-.Xr man 7
-text from stdin, implying
-.Fl m Ns Cm andoc ,
-and produces
-.Fl T Ns Cm ascii
-output.
.Ss Input Formats
The
.Nm
utility accepts the following
.Fl T
arguments, which correspond to output modes:
-.Bl -tag -width Ds
+.Bl -tag -width "-Tlocale"
.It Fl T Ns Cm ascii
Produce 7-bit ASCII output.
This is the default.
Parse only: produce no output.
Implies
.Fl W Ns Cm warning .
+.It Fl T Ns Cm locale
+Encode output using the current locale.
+See
+.Sx Locale Output .
+.It Fl T Ns Cm man
+Produce
+.Xr man 7
+format output.
+See
+.Sx Man Output .
.It Fl T Ns Cm pdf
Produce PDF output.
See
.Sx PostScript Output .
.It Fl T Ns Cm tree
Produce an indented parse tree.
+.It Fl T Ns Cm utf8
+Encode output in the UTF\-8 multi-byte format.
+See
+.Sx UTF\-8 Output .
.It Fl T Ns Cm xhtml
Produce strict CSS1/XHTML-1.0 output.
See
The special characters documented in
.Xr mandoc_char 7
are rendered best-effort in an ASCII equivalent.
+If no equivalent is found,
+.Sq \&?
+is used instead.
.Pp
Output width is limited to 78 visible columns unless literal input lines
exceed this limit.
.Fl O
arguments are accepted:
.Bl -tag -width Ds
+.It Cm indent Ns = Ns Ar indent
+The left margin for normal text is set to
+.Ar indent
+blank characters instead of the default of five for
+.Xr mdoc 7
+and seven for
+.Xr man 7 .
+Increasing this is not recommended; it may result in degraded formatting,
+for example overfull lines or ugly line breaks.
.It Cm width Ns = Ns Ar width
The output width is set to
.Ar width ,
.Fl T Ns Cm html
conforms to HTML-4.01 strict.
.Pp
-Font styles and page structure are applied using CSS1.
-By default, no font style is applied to any text,
-although CSS1 is hard-coded to format
-the basic structure of output.
-.Pp
The
.Pa example.style.css
-file documents the range of styles applied to output and, if used, will
-cause rendered documents to appear as they do in
-.Fl T Ns Cm ascii .
+file documents style-sheet classes available for customising output.
+If a style-sheet is not specified with
+.Fl O Ns Ar style ,
+.Fl T Ns Cm html
+defaults to simple output readable in any graphical or text-based web
+browser.
.Pp
-Special characters are rendered in decimal-encoded UTF-8.
+Special characters are rendered in decimal-encoded UTF\-8.
.Pp
The following
.Fl O
arguments are accepted:
.Bl -tag -width Ds
+.It Cm fragment
+Omit the
+.Aq !DOCTYPE
+declaration and the
+.Aq html ,
+.Aq head ,
+and
+.Aq body
+elements and only emit the subtree below the
+.Aq body
+element.
+The
+.Cm style
+argument will be ignored.
+This is useful when embedding manual content within existing documents.
.It Cm includes Ns = Ns Ar fmt
The string
.Ar fmt ,
This must be a valid absolute or
relative URI.
.El
+.Ss Locale Output
+Locale-depending output encoding is triggered with
+.Fl T Ns Cm locale .
+This option is not available on all systems: systems without locale
+support, or those whose internal representation is not natively UCS-4,
+will fall back to
+.Fl T Ns Cm ascii .
+See
+.Sx ASCII Output
+for font style specification and available command-line arguments.
+.Ss Man Output
+Translate input format into
+.Xr man 7
+output format.
+This is useful for distributing manual sources to legancy systems
+lacking
+.Xr mdoc 7
+formatters.
+.Pp
+If
+.Xr mdoc 7
+is passed as input, it is translated into
+.Xr man 7 .
+If the input format is
+.Xr man 7 ,
+the input is copied to the output, expanding any
+.Xr roff 7
+.Sq 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 PDF Output
+PDF-1.1 output may be generated by
+.Fl T Ns Cm pdf .
+See
+.Sx PostScript Output
+for
+.Fl O
+arguments and defaults.
.Ss PostScript Output
PostScript
.Qq Adobe-3.0
.Ar letter
is used.
.El
-.Ss PDF Output
-PDF-1.1 output may be generated by
-.Fl T Ns Cm pdf .
+.Ss UTF\-8 Output
+Use
+.Fl T Ns Cm utf8
+to force a UTF\-8 locale.

-for
-.Fl O
-arguments and defaults.
+.Sx Locale Output
+for details and options.
