+Since
+.Xr mdoc 7
+is semantic and
+.Xr perlpod 1
+is not,
+.Nm
+tries to figure out semantic context for some terms.
+Specifically, within each paragraph of the SYNOPSIS section, the
+following occur:
+.Bl -bullet
+.It
+If any number of
+.Li #include <foo.h>
+lines are found at the start of a verbatim paragraph, they're rendered
+with
+.Sq \&In .
+.It
+Other lines starting with
+.Sq #
+are rendered with
+.Sq \&Fd .
+.It
+An initial
+.Li B<>
+format code is rendered as
+.Sq \&Nm .
+.It
+Subsequent
+.Li B<>
+format codes are rendered as
+.Sq \&Ar .
+However, if the leading character of a
+.Li B<>
+format code is
+.Sq - ,
+it is rendered as
+.Sq \&Fl .
+Subsequent space-separated terms without leading hyphens, e.g.,
+.Li B<-foo bar> ,
+are rendered as
+.Sq \&Ar .
+.It
+Matching
+.Li \&[
+and
+.Li \&]
+pairs are rendered as
+.Sq \&Oo
+and
+.Sq \&Oc .
+.El
+.Pp
+Thus, the input
+.Li B<foo> [B<-bar baz>]
+is rendered as follows:
+.Bd -literal
+\&.Nm foo
+\&.Oo
+\&.Fl bar Ar baz
+\&.Oc
+.Ed
+.Pp
+In the NAME section,
+.Sq \&Nm
+and
+.Sq \&Nd
+macros are inferred from text leading and trailing the last hyphen
+followed by a space (there may be any number of hyphens preceding the
+space).
+The space may occur on either side of the hyphen.
+Thus,
+.Li B<foo> - bar
+will be rendered as follows:
+.Bd -literal
+\&.Nm foo
+\&.Nd bar
+.Ed
+.Pp
+Multiple names separated by a comma are properly handled.
+.Pp
+In any section, the
+.Li L<>
+format code is considered a
+.Sq \&Lk
+link if beginning with
+.Li http: ,
+.Li https: ,
+.Li ftp: ,
+.Li sftp: ,
+.Li smb: ,
+or
+.Li afs: .
+If beginning with
+.Li mailto: ,
+it is considered a
+.Sq \&Mt
+link.
+Otherwise, it is considered a
+.Sq \&Xr
+manpage in section 3P if containing double-colons or section 1
+otherwise.
+The section may be overriden as
+.Li L<foo(5)> .
+If only a section appears, such as in
+.Li </section> ,
+the link is rendered with
+.Sq \&Sx .
+.Pp
+Words followed by
+.Qq Pq
+that match function names listed in the SYNOPSIS section are marked up with
+.Sq \&Fn .
+.Pp
+If the contents of a
+.Li B<>
+format code matches a type name mentioned in the SYNOPSIS section,
+it is rendered as
+.Sq \&Vt .
+If it matches a function argument name mentioned there,
