.Nd man language reference
.\" SECTION
.Sh DESCRIPTION
The
.Nm man
language was historically used to format 
.Ux
manuals.  In this reference document, we describe the syntax and
structure of the 
.Nm
language.
.Pp
.Em \&Do not
use 
.Nm
to write your manuals.  Use the
.Xr mdoc 7
language, instead.
.\" PARAGRAPH
.Pp
An
.Nm
document follows simple rules:  lines beginning with the control
character 
.Sq \.
are parsed for macros.  Other lines are interpreted within the scope of
prior macros:
.Bd -literal -offset XXX
\&.SH Macro lines change control state.
Other lines are interpreted within the current state.
.Ed
.\" PARAGRAPH
.Pp
Macros are character sequences whose structural rules are described
later in this document.
.\" SECTION
.Sh INPUT ENCODING
.Nm
documents may contain only graphable 7-bit ASCII characters and the
space character
.Sq \  .
All manuals must have
.Sq \en
line termination.  
.Pp
Blank lines are acceptable; where found, the output will also assert a
vertical space.
.\" SUB-SECTION
.Ss Special Characters
Special character sequences begin with the escape character
.Sq \\
followed by either an open-parenthesis 
.Sq \&(
for two-character sequences; an open-bracket
.Sq \&[
for n-character sequences (terminated at a close-bracket
.Sq \&] ) ;
or a single one-character sequence.
.Pp
Characters may alternatively be escaped by a slash-asterisk,
.Sq \\* ,
with the same combinations as described above.  This form is deprecated.  
.Pp
The following is a table of all available escapes.
