.Sh SYNOPSIS
.Nm mandoc
.Op Fl V
.Op Fl f Ns Ar option...
.Op Fl W Ns Ar err...
.Op Fl T Ns Ar output
.Op Ar infile...
.\" SECTION
.Sh DESCRIPTION
The
.Nm
utility formats a BSD
.Dq mdoc
manual page for display. The arguments are as follows:
.Bl -tag -width XXXXXXXXXXXX
.\" ITEM
.It Fl f Ns Ar option...
Override default compiler behaviour. See
.Sx Compiler Options
for details.
.\" ITEM
.It Fl T
Output format. See
.Sx Output Formats
for available formats. Defaults to
.Fl T Ns Ar ascii .
.\" ITEM
.It Fl V
Print version and exit.
.\" ITEM
.It Fl W Ns Ar err...
Print warning messages. May be set to
.Fl W Ns Ar all
for all warnings,
.Ar compat
for groff/troff-compatibility warnings, or
.Ar syntax
for syntax warnings. If
.Fl W Ns Ar error
is specified, warnings are considered errors and cause utility
termination. Multiple
.Fl W
arguments may be comma-separated, such as
.Fl W Ns Ar error,all .
.\" ITEM
.It Ar infile...
Read input from zero or more
.Ar infile .
If unspecified, reads from stdin. If multiple files are specified,
.Nm
will halt with the first failed parse.
.El
.\" PARAGRAPH
.Pp
By default,
.Nm
reads from stdin and prints 78-column backspace-encoded output to stdout
as if
.Fl T Ns Ar ascii
were provided.
.\" PARAGRAPH
.Pp

.\" SUB-SECTION
.Ss Reserved Words
The reserved words described in
.Xr mdoc 7
are handled according to the following rules:
.Bl -enum -offset XXX
.It
Opening delimiters
.Po
.Sq \&( ,
.Sq \&[ ,
and
.Sq \&{
.Pc are not followed by whitespace.
.It
Closing delimiters
.Po
.Sq \&. ,
.Sq \&, ,
.Sq \&; ,
.Sq \&: ,
.Sq \&? ,
.Sq \&! ,
.Sq \&) ,
.Sq \&]
and
.Sq \&}
.Pc are not preceeded by whitespace.
.El
.\" PARAGRAPH
.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
.Ed
.\" PARAGRAPH
.Pp
\&...correctly adjusts the comma spacing to
.Qq this self is not that of the waking , empirically real man .
.\" SUB-SECTION
.Ss Output Formats
The
.Nm
utility accepts the following
.Fl T
arguments:
.Bl -tag -width XXXXXXXXXXXX -offset XXXX
.It Ar ascii
Produce 7-bit ASCII output, backspace-encoded for bold and underline
styles. This is the default.
.It Ar tree
Produce an indented parse tree.
.It Ar lint
Parse only: produce no output.
.El
.\" SUB-SECTION
.Ss Compiler Options
Default compiler behaviour may be overriden with the
.Fl f
flag.
.Bl -tag -width XXXXXXXXXXXX -offset XXXX
.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.
.It Fl f Ns Ar ign-macro
Ignore unknown macros at the start of input lines.
.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,ign-escape ,
for example, will try to ignore scope and character-escape errors.

.\" SECTION
.Sh CAVEATS
The
.Nm
utility in
.Fl T Ns Ar ascii
mode doesn't yet know how to display the following:
.Pp
.Bl -bullet -compact
.It
The \-hang
.Sq \&Bl
list is not yet supported.
.\" LIST-ITEM
.It
The \-literal and \-unfilled
.Sq \&Bd
displays types are synonyms, as are \-filled and \-ragged.
.\" LIST-ITEM
.It
The
.Sq \&Xo/Xc
pair isn't supported.
.\" LIST-ITEM
.It
The
.Sq \&Bd
macro doesn't process \-compact .
.El
.Pp
Other macros still aren't supported by virtue of nobody complaining
about their absence. Please report any omissions: this is a work in
progress.
