.Ss Punctuation and Spacing
If punctuation is set apart from words, such as in the phrase
.Dq to be \&, or not to be ,
.Sq \&}
.Pc
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
+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.,
+.Sq \&Bd \-literal
in
.Xr mdoc 7 .
-.\" SUB-SECTION
+.
+.
.Ss Input Formats
The
.Nm
recommended;
.Xr man 7
should only be used for legacy manuals.
+.
.Pp
A third option,
.Fl m Ns Ar andoc ,
which is also the default, determines encoding on-the-fly: if the first
non-comment macro is
-.Sq \&.Dd
+.Sq \&Dd
or
-.Sq \&.Dt ,
+.Sq \&Dt ,
the
.Xr mdoc 7
parser is used; otherwise, the
.Xr man 7
parser is used.
+.
.Pp
If multiple
files are specified with
or
.Fl m Ns Ar an

.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.

.Ss Compiler Options

+Default compiler behaviour may be overridden with the
.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.
.Pq mdoc only
+.
.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.
+.
.It Fl f Ns Ar no-ign-chars
Do not ignore disallowed characters.
+.
.It Fl f Ns Ar strict
Implies
.Fl f Ns Ar no-ign-escape ,
.Fl f Ns Ar no-ign-macro
and
.Fl f Ns Ar no-ign-chars .
+.
+.It Fl f Ns Ar ign-errors
+Don't halt when encountering parse errors. Useful with
+.Fl T Ns Ar lint
+over a large set of manuals passed on the command line.
.El
-.\" PARAGRAPH
-.Pp
-As with the
-.Fl W
-flag, multiple
-.Fl f
-options may be grouped and delimited with a comma. Using
-.Fl f Ns Ar ign-scope,no-ign-escape ,
-for example, will try to ignore scope and not ignore character-escape
-errors.
-.\" SECTION
+.
+.Ss Output Options
+For the time being, only
+.Fl T Ns Ar html
+is the only mode with output options:
+.Bl -tag -width Ds
+.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 base=http://base/
+The URL
+.Ar http://base/
+is used as a base URL for all relative links. This is useful when
+linking between documents via the
+.Sq \&Xr
+macro.
