.Nm mdoc
.Nd mdoc macro reference
.\" SECTION
.Sh DESCRIPTION
The
.Nm mdoc
language is used to format 
.Bx 
.Ux
manuals.  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.  Macros are either two or three characters in length.
.\" SECTION
.Sh CHARACTER ENCODING
.Nm
documents may contain only printable alphanumeric characters, the space
character
.Sq \  ,
and, in certain circumstances, the tab character
.Sq \et .
All manuals must have
.Sq \en
line termination.
.\" SUB-SECTION
.Ss Special Characters
Within a macro line, the following characters are special:
.\" PARAGRAPH
.Pp
.Bl -tag -width Ds -offset XXXX -compact
.It \&.

.It \&,
comma
.It \&:
colon

.It \&)
right-parenthesis
.It \&[
left-bracket
.It \&]
right-bracket
.It \&?
question
.It \&!
exclmamation 
.El
.Pp
Use of these characters must either be escaped with a non-breaking space
.Pq Sq \e&
or, if applicable, an appropriate escape-sequence used.
.\" SUB-SECTION
.Ss Special Characters
Special character sequences begin with the escape character
.Sq \\
and 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, however, is
deprecated.  The following is a table of all available escapes, arranged
by classification.

.\" SECTION
.Sh CLASSIFICATION
Macros are classified in an ontology described by scope rules.  
.Bl -tag -width "in-lineX"
.\" LIST-ITEM
.It Em Block
Block macros enclose other block macros, in-line macros or text, and
may span multiple lines.  
.Qq Implicit 
block scope is closed by a subsequent invocation of the same macro,
one of a set of corresponding closure macros or end-of-file.
.Qq Explicit 
block scope is closed by a corresponding closure macro.
.Bl -tag -width "partial-blockX"
.\" LIST-ITEM
.It Em Full-block
Always spans multiple lines.  Consists optionally of one or more
.Qq heads ,
subsequent macros or text on the same line following invocation; a
.Qq body ,
which spans subsequent lines of text or macros; and an optional
.Qq tail ,
macros or text on the same line following closure.
.\" LIST-ITEM
.It Em Partial-block
May span multiple lines.  Consists optionally of a 
.Qq head ,
text immediately following invocation; always a 
.Qq body ,
text or macros following the head on the same and subsequent lines; and
optionally a
.Qq tail ,
text immediately following closure.
.El
.\" LIST-ITEM
.It Em In-line
In-line macros may only enclose text and span at most a single line.  If
a macro is parsable, its scope may be closed by subsequent macros or
delimiting punctuation.  In-line macros follow different conventions for
closure; see 
.Sx MACROS 
for per-macro details.
