.Ss Punctuation and Spacing
If punctuation is set apart from words, such as in the phrase
.Dq to be \&, or not to be ,
.Nm
according to the following rules: opening punctuation
.Po
-.Sq \&( ,
-.Sq \&[ ,
+.Sq \&( ,
+.Sq \&[ ,
and
.Sq \&{
-.Pc
+.Pc
is not followed by a space; closing punctuation
.Po

and

is not preceded by whitespace.
+.
.Pp
If the input is
.Xr mdoc 7 ,
these rules are also applied to macro arguments when appropriate.
+.
.Pp
White-space, in non-literal (normal) mode, is stripped from input and
-replaced on output by a single space. Thus, if you wish to preserve
-multiple spaces, they must be space-escaped
-.Sq \e\ .
-or used in a literal display mode, e.g.,
-.Sq \&.Bd \-literal
-in
+replaced on output by a single space. Thus, if you wish to preserve multiple
+spaces, they must be space-escaped or used in a literal display mode, e.g.,

.Ss Input Formats
The

.Xr mdoc 7
format is

.Xr man 7
should only be used for legacy manuals.

A third option,

-the

parser is used.

.Pp
If multiple

+files are specified with

each has its file-type determined this way. If multiple files are
specified and

.Ss Output Formats
The
.Nm
utility accepts the following
.Fl T
arguments:
+.
.Bl -tag -width Ds
.It Fl T Ns Ar ascii
Produce 7-bit ASCII output, backspace-encoded for bold and underline
styles. This is the default.
+.
+.It Fl T Ns Ar html
+Produce strict HTML-4.01 output, with a sane default style.
+.
.It Fl T Ns Ar tree
Produce an indented parse tree.
+.
.It Fl T Ns Ar lint
Parse only: produce no output.
.El
+.
.Pp
If multiple input files are specified, these will be processed by the
corresponding filter in-order.

.Fl f
flag.

.Bl -tag -width Ds
.It Fl f Ns Ar ign-scope
When rewinding the scope of a block macro, forces the compiler to ignore
scope violations. This can seriously mangle the resulting tree.

+.It Fl f Ns Ar ign-escape
+Ignore invalid escape sequences.
+This is the default, but the option can be used to override an earlier
+.Fl f Ns Ar strict .
+.
.It Fl f Ns Ar no-ign-escape
Don't ignore invalid escape sequences.
+.
.It Fl f Ns Ar no-ign-macro
Do not ignore unknown macros at the start of input lines.

+.Ss Output Options
+For the time being, only

+is the only mode with output options:

+.It Fl O Ns Ar style=style.css
+The file
+.Ar style.css
+is used for an external style-sheet. This must be a valid absolute or
+relative URI.
+.It Fl O Ns Ar includes=fmt
+The string
+.Ar fmt ,
+for example,
+.Ar ../src/%I.html ,
+is used as a template for linked header files (usually via the
+.Sq \&In
+macro). Instances of
+.Sq \&%I
+are replaced with the include filename. The default is not to present a
+hyperlink.
+.It Fl O Ns Ar man=fmt
+The string
+.Ar fmt ,
+for example,
+.Ar ../html%S/%N.%S.html ,
+is used as a template for linked manuals (usually via the
+.Sq \&Xr
+macro). Instances of
+.Sq \&%N
+and
+.Sq %S
+are replaced with the linked manual's name and section, respectively.
+If no section is included, section 1 is assumed. The default is not to
+present a hyperlink.
