-.Ss Reserved Words

+If punctuation is set apart from words, such as in the phrase

+it's processed by

+according to the following rules: opening punctuation
.Po
.Sq \&( ,

and

-.Pc are not followed by whitespace.

-Closing delimiters
+.Pc
+is not followed by a space; closing punctuation

.Pp
-Note that reserved words may occur in streams of text, so the following:
-.Bd -literal -offset XXXX
-this self is not that of the waking , empirically real man

-.\" PARAGRAPH
+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.,

+.Ss Input Formats
+The
+.Nm
+utility accepts
+.Xr mdoc 7
+and
+.Xr man 7
+input with
+.Fl m Ns Ar doc
+and
+.Fl m Ns Ar 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 Ar 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
-\&...correctly adjusts the comma spacing to
-.Qq this self is not that of the waking , empirically real man .
+If multiple
+files are specified with
+.Fl m Ns Ar andoc ,
+each has its file-type determined this way. If multiple files are
+specified and
+.Fl m Ns Ar doc
+or
+.Fl m Ns Ar an
+is specified, then this format is used exclusively.

+.It Fl T Ns Ar ascii
Produce 7-bit ASCII output, backspace-encoded for bold and underline
styles. This is the default.
