If the input is

these rules are also applied to macro arguments when appropriate.

White-space, in non-literal (normal) mode, is stripped from input 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.

+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 ,

+.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 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.
