+.Sh NAME
+.Nm man
+.Nd man language reference
+.Sh DESCRIPTION
+The
+.Nm man
+language was historically used to format
+.Ux
+manuals.
+This reference document describes its syntax, structure, and usage.
+.Pp
+.Bf -emphasis
+Do not use
+.Nm
+to write your manuals.
+.Ef
+Use the
+.Xr mdoc 7
+language, instead.
+.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 indent
+\&.SH Macro lines change control state.
+Other lines are interpreted within the current state.
+.Ed
+.Sh INPUT ENCODING
+.Nm
+documents may contain only graphable 7-bit ASCII characters, the
+space character, and the tabs character.
+All manuals must have
+.Ux
+line termination.
+.Pp
+Blank lines are acceptable; where found, the output will assert a
+vertical space.
+.Ss Comments
+Text following a
+.Sq \e\*" ,
+whether in a macro or free-form text line, is ignored to the end of
+line.
+A macro line with only a control character and comment escape,
+.Sq \&.\e" ,
+is also ignored.
+Macro lines with only a control character and optionally whitespace are
+stripped from input.
+.Ss Special Characters
+Special characters may occur in both macro and free-form lines.
+Sequences begin with the escape character
+.Sq \e
+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.
+See
+.Xr mandoc_char 7
+for a complete list.
+Examples include
+.Sq \e(em
+.Pq em-dash
+and
+.Sq \ee
+.Pq back-slash .
+.Ss Text Decoration
+Terms may be text-decorated using the
+.Sq \ef
+escape followed by an indicator: B (bold), I, (italic), R (Roman), or P
+(revert to previous mode):
+.Pp
+.D1 \efBbold\efR \efIitalic\efP
+.Pp
+A numerical representation 3, 2, or 1 (bold, italic, and Roman,
+respectively) may be used instead.
+A text decoration is only valid, if specified in free-form text, until
+the next macro invocation; if specified within a macro, it's only valid
+until the macro closes scope.
+Note that macros like
+.Sx \&BR
+open and close a font scope with each argument.
+.Pp
+Text may also be sized with the
+.Sq \es
+escape, whose syntax is one of
+.Sq \es+-n
+for one-digit numerals;
+.Sq \es(+-nn
+or
+.Sq \es+-(nn
+for two-digit numerals; and
+.Sq \es[+-N] ,
+.Sq \es+-[N] ,
+.Sq \es'+-N' ,
+or
+.Sq \es+-'N'
+for arbitrary-digit numerals:
+.Pp
+.D1 \es+1bigger\es-1
+.D1 \es[+10]much bigger\es[-10]
+.D1 \es+(10much bigger\es-(10
+.D1 \es+'100'much much bigger\es-'100'
+.Pp
+Both
+.Sq \es
+and
+.Sq \ef
+attributes are forgotten when entering or exiting a macro block.
+.Ss Whitespace
+Whitespace consists of the space character.
+In free-form lines, whitespace is preserved within a line; un-escaped
+trailing spaces are stripped from input (unless in a literal context).
+Blank free-form lines, which may include spaces, are permitted and
+rendered as an empty line.
+.Pp
+In macro lines, whitespace delimits arguments and is discarded.
+If arguments are quoted, whitespace within the quotes is retained.
+.Ss Dates
+The
+.Sx \&TH
+macro is the only
+.Nm
+macro that requires a date.
+The form for this date is the ISO-8601
+standard
+.Cm YYYY-MM-DD .
+.Ss Scaling Widths
+Many macros support scaled widths for their arguments, such as
+stipulating a two-inch paragraph indentation with the following:
+.Bd -literal -offset indent
+\&.HP 2i
+.Ed
+.Pp
+The syntax for scaled widths is
+.Sq Li [+-]?[0-9]*.[0-9]*[:unit:]? ,
+where a decimal must be preceded or proceeded by at least one digit.
+Negative numbers, while accepted, are truncated to zero.
+The following scaling units are accepted:
+.Pp
+.Bl -tag -width Ds -offset indent -compact
+.It c
+centimetre
+.It i
+inch
+.It P
+pica (~1/6 inch)
+.It p
+point (~1/72 inch)
+.It f
+synonym for
+.Sq u
+.It v
+default vertical span
+.It m
+width of rendered
+.Sq m
+.Pq em
+character
+.It n
+width of rendered
+.Sq n
+.Pq en
+character
+.It u
+default horizontal span
+.It M
+mini-em (~1/100 em)
+.El
+.Pp
+Using anything other than
+.Sq m ,
+.Sq n ,
+.Sq u ,
+or
+.Sq v
+is necessarily non-portable across output media.
+.Pp
+If a scaling unit is not provided, the numerical value is interpreted
+under the default rules of
+.Sq v
+for vertical spaces and
+.Sq u
+for horizontal ones.
+.Em Note :
+this differs from
+.Xr mdoc 7 ,
+which, if a unit is not provided, will instead interpret the string as
+literal text.
+.Ss Sentence Spacing
+When composing a manual, make sure that your sentences end at the end of
+a line.
+By doing so, front-ends will be able to apply the proper amount of
+spacing after the end of sentence (unescaped) period, exclamation mark,
+or question mark followed by zero or more non-sentence closing
+delimiters (
+.Ns Sq \&) ,
+.Sq \&] ,
+.Sq \&' ,
+.Sq \&" ) .
+.Sh MANUAL STRUCTURE
+Each
+.Nm
+document must contain contains at least the
+.Sx \&TH
+macro describing the document's section and title.
+It may occur anywhere in the document, although conventionally, it
+appears as the first macro.
+.Pp
+Beyond
+.Sx \&TH ,
+at least one macro or text node must appear in the document.
+Documents are generally structured as follows:
+.Bd -literal -offset indent

+The sections in a
+.Nm
+document are conventionally ordered as they appear above.
+Sections should be composed as follows:
+.Bl -ohang -offset indent
+.It Em NAME
+The name(s) and a short description of the documented material.
+The syntax for this is generally as follows:
+.Pp
+.D1 \efBname\efR \e(en description
+.It Em LIBRARY
+The name of the library containing the documented material, which is
+assumed to be a function in a section 2 or 3 manual.
+For functions in the C library, this may be as follows:
+.Pp
+.D1 Standard C Library (libc, -lc)
+.It Em SYNOPSIS
+Documents the utility invocation syntax, function call syntax, or device
+configuration.
+.Pp
+For the first, utilities (sections 1, 6, and 8), this is
+generally structured as follows:
+.Pp
+.D1 \efBname\efR [-\efBab\efR] [-\efBc\efR\efIarg\efR] \efBpath\efR...
+.Pp
+For the second, function calls (sections 2, 3, 9):
+.Pp

+.Pp
+And for the third, configurations (section 4):
+.Pp
+.D1 \&.B name* at cardbus ? function ?
+.Pp
+Manuals not in these sections generally don't need a
+.Em SYNOPSIS .
+.It Em DESCRIPTION
+This expands upon the brief, one-line description in
+.Em NAME .
+It usually contains a break-down of the options (if documenting a
+command).
+.It Em IMPLEMENTATION NOTES
+Implementation-specific notes should be kept here.
+This is useful when implementing standard functions that may have side
+effects or notable algorithmic implications.
+.It Em RETURN VALUES
+This section is the dual of
+.Em EXIT STATUS ,
+which is used for commands.
+It documents the return values of functions in sections 2, 3, and 9.
+.It Em ENVIRONMENT
+Documents any usages of environment variables, e.g.,
+.Xr environ 7 .
+.It Em FILES
+Documents files used.
+It's helpful to document both the file and a short description of how
+the file is used (created, modified, etc.).
+.It Em EXIT STATUS
+Command exit status for section 1, 6, and 8 manuals.
+This section is the dual of
+.Em RETURN VALUES ,
+which is used for functions.
+Historically, this information was described in
+.Em DIAGNOSTICS ,
+a practise that is now discouraged.
+.It Em EXAMPLES
+Example usages.
+This often contains snippets of well-formed,
+well-tested invocations.
+Make doubly sure that your examples work properly!
+.It Em DIAGNOSTICS
+Documents error conditions.
+This is most useful in section 4 manuals.
+Historically, this section was used in place of
+.Em EXIT STATUS
+for manuals in sections 1, 6, and 8; however, this practise is
+discouraged.
+.It Em ERRORS
+Documents error handling in sections 2, 3, and 9.
+.It Em SEE ALSO
+References other manuals with related topics.
+This section should exist for most manuals.
+.Pp
+.D1 \&.BR bar \&( 1 \&),
+.Pp
+Cross-references should conventionally be ordered

+.Pp
+.D1 IEEE Std 1003.2 (\e(lqPOSIX.2\e(rq)
+.Pp
+If not adhering to any standards, the
+.Em HISTORY
+section should be used.
+.It Em HISTORY
+The history of any manual without a
+.Em STANDARDS
+section should be described in this section.
+.It Em AUTHORS
+Credits to authors, if applicable, should appear in this section.
+Authors should generally be noted by both name and an e-mail address.
+.It Em CAVEATS
+Explanations of common misuses and misunderstandings should be explained
+in this section.
+.It Em BUGS
+Extant bugs should be described in this section.
+.It Em SECURITY CONSIDERATIONS
+Documents any security precautions that operators should consider.
+.El
+.Sh MACRO SYNTAX
+Macros are one to three three characters in length and begin with a
+control character ,
+.Sq \&. ,
+at the beginning of the line.
+The
+.Sq \(aq
+macro control character is also accepted.
+An arbitrary amount of whitespace (spaces or tabs) may sit between the
+control character and the macro name.
+Thus, the following are equivalent:
+.Bd -literal -offset indent
+\&.PP
+\&.\ \ \ PP
+.Ed
+.Pp
+The
+.Nm
+macros are classified by scope: line scope or block scope.
+Line macros are only scoped to the current line (and, in some
+situations, the subsequent line).
+Block macros are scoped to the current line and subsequent lines until
+closed by another block macro.
+.Ss Line Macros
+Line macros are generally scoped to the current line, with the body
+consisting of zero or more arguments.
+If a macro is scoped to the next line and the line arguments are empty,
+the next line, which must be text, is used instead.
+Thus:
+.Bd -literal -offset indent
+\&.I
+foo
+.Ed
+.Pp
+is equivalent to
+.Sq \&.I foo .
+If next-line macros are invoked consecutively, only the last is used.
+If a next-line macro is followed by a non-next-line macro, an error is
+raised (unless in the case of
+.Sx \&br ,
+.Sx \&sp ,
+or
+.Sx \&na ) .
+.Pp
+The syntax is as follows:
+.Bd -literal -offset indent

+.Pp
+Macros marked as
+.Qq compat
+are included for compatibility with the significant corpus of existing
+manuals that mix dialects of roff.
+These macros should not be used for portable
+.Nm
+manuals.
+.Ss Block Macros
+Block macros are comprised of a head and body.
+Like for in-line macros, the head is scoped to the current line and, in
+one circumstance, the next line (the next-line stipulations as in
+.Sx Line Macros
+apply here as well).
+.Pp
+The syntax is as follows:
+.Bd -literal -offset indent
+\&.YO \(lBhead...\(rB
+\(lBhead...\(rB
+\(lBbody...\(rB
+.Ed
+.Pp
+The closure of body scope may be to the section, where a macro is closed
+by
+.Sx \&SH ;
+sub-section, closed by a section or
+.Sx \&SS ;
+part, closed by a section, sub-section, or
+.Sx \&RE ;
+or paragraph, closed by a section, sub-section, part,
+.Sx \&HP ,
+.Sx \&IP ,
+.Sx \&LP ,
+.Sx \&P ,
+.Sx \&PP ,
+or
+.Sx \&TP .
+No closure refers to an explicit block closing macro.
+.Pp
+As a rule, block macros may not be nested; thus, calling a block macro
+while another block macro scope is open, and the open scope is not
+implicitly closed, is syntactically incorrect.

-.Dt MAN 7
-.Os
-.Sh NAME
-.Nm man
-.Nd man language reference
-.Sh DESCRIPTION
-The
-.Nm man
-language was historically used to format
-.Ux
-manuals.
-This reference document describes its syntax, structure, and usage.
-.Pp
-.Bf -emphasis
-Do not use
-.Nm
-to write your manuals.
-.Ef
-Use the
-.Xr mdoc 7
-language, instead.
-.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 indent
-\&.SH Macro lines change control state.
-Other lines are interpreted within the current state.
-.Ed
-.Sh INPUT ENCODING
-.Nm
-documents may contain only graphable 7-bit ASCII characters, the
-space character, and the tabs character.
-All manuals must have
-.Ux
-line termination.
-.Pp
-Blank lines are acceptable; where found, the output will assert a
-vertical space.
-.Ss Comments
-Text following a
-.Sq \e\*" ,
-whether in a macro or free-form text line, is ignored to the end of
-line.
-A macro line with only a control character and comment escape,
-.Sq \&.\e" ,
-is also ignored.
-Macro lines with only a control character and optionally whitespace are
-stripped from input.
-.Ss Special Characters
-Special characters may occur in both macro and free-form lines.
-Sequences begin with the escape character
-.Sq \e
-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.
-See
-.Xr mandoc_char 7
-for a complete list.
-Examples include
-.Sq \e(em
-.Pq em-dash
-and
-.Sq \ee
-.Pq back-slash .
-.Ss Text Decoration
-Terms may be text-decorated using the
-.Sq \ef
-escape followed by an indicator: B (bold), I, (italic), R (Roman), or P
-(revert to previous mode):
-.Pp
-.D1 \efBbold\efR \efIitalic\efP
-.Pp
-A numerical representation 3, 2, or 1 (bold, italic, and Roman,
-respectively) may be used instead.
-A text decoration is only valid, if specified in free-form text, until
-the next macro invocation; if specified within a macro, it's only valid
-until the macro closes scope.
-Note that macros like
-.Sx \&BR
-open and close a font scope with each argument.
-.Pp
-Text may also be sized with the
-.Sq \es
-escape, whose syntax is one of
-.Sq \es+-n
-for one-digit numerals;
-.Sq \es(+-nn
-or
-.Sq \es+-(nn
-for two-digit numerals; and
-.Sq \es[+-N] ,
-.Sq \es+-[N] ,
-.Sq \es'+-N' ,
-or
-.Sq \es+-'N'
-for arbitrary-digit numerals:
-.Pp
-.D1 \es+1bigger\es-1
-.D1 \es[+10]much bigger\es[-10]
-.D1 \es+(10much bigger\es-(10
-.D1 \es+'100'much much bigger\es-'100'
-.Pp
-Both
-.Sq \es
-and
-.Sq \ef
-attributes are forgotten when entering or exiting a macro block.
-.Ss Whitespace
-Whitespace consists of the space character.
-In free-form lines, whitespace is preserved within a line; un-escaped
-trailing spaces are stripped from input (unless in a literal context).
-Blank free-form lines, which may include spaces, are permitted and
-rendered as an empty line.
-.Pp
-In macro lines, whitespace delimits arguments and is discarded.
-If arguments are quoted, whitespace within the quotes is retained.
-.Ss Dates
-The
-.Sx \&TH
-macro is the only
-.Nm
-macro that requires a date.
-The form for this date is the ISO-8601
-standard
-.Cm YYYY-MM-DD .
-.Ss Scaling Widths
-Many macros support scaled widths for their arguments, such as
-stipulating a two-inch paragraph indentation with the following:
-.Bd -literal -offset indent
-\&.HP 2i
-.Ed
-.Pp
-The syntax for scaled widths is
-.Sq Li [+-]?[0-9]*.[0-9]*[:unit:]? ,
-where a decimal must be preceded or proceeded by at least one digit.
-Negative numbers, while accepted, are truncated to zero.
-The following scaling units are accepted:
-.Pp
-.Bl -tag -width Ds -offset indent -compact
-.It c
-centimetre
-.It i
-inch
-.It P
-pica (~1/6 inch)
-.It p
-point (~1/72 inch)
-.It f
-synonym for
-.Sq u
-.It v
-default vertical span
-.It m
-width of rendered
-.Sq m
-.Pq em
-character
-.It n
-width of rendered
-.Sq n
-.Pq en
-character
-.It u
-default horizontal span
-.It M
-mini-em (~1/100 em)
-.El
-.Pp
-Using anything other than
-.Sq m ,
-.Sq n ,
-.Sq u ,
-or
-.Sq v
-is necessarily non-portable across output media.
-.Pp
-If a scaling unit is not provided, the numerical value is interpreted
-under the default rules of
-.Sq v
-for vertical spaces and
-.Sq u
-for horizontal ones.
-.Em Note :
-this differs from
-.Xr mdoc 7 ,
-which, if a unit is not provided, will instead interpret the string as
-literal text.
-.Ss Sentence Spacing
-When composing a manual, make sure that your sentences end at the end of
-a line.
-By doing so, front-ends will be able to apply the proper amount of
-spacing after the end of sentence (unescaped) period, exclamation mark,
-or question mark followed by zero or more non-sentence closing
-delimiters (
-.Ns Sq \&) ,
-.Sq \&] ,
-.Sq \&' ,
-.Sq \&" ) .
-.Sh MANUAL STRUCTURE
-Each
-.Nm
-document must contain contains at least the
-.Sx \&TH
-macro describing the document's section and title.
-It may occur anywhere in the document, although conventionally, it
-appears as the first macro.
-.Pp
-Beyond
-.Sx \&TH ,
-at least one macro or text node must appear in the document.
-Documents are generally structured as follows:
-.Bd -literal -offset indent

-.Pp
-The sections in a
-.Nm
-document are conventionally ordered as they appear above.
-Sections should be composed as follows:
-.Bl -ohang -offset indent
-.It Em NAME
-The name(s) and a short description of the documented material.
-The syntax for this is generally as follows:
-.Pp
-.D1 \efBname\efR \e(en description
-.It Em LIBRARY
-The name of the library containing the documented material, which is
-assumed to be a function in a section 2 or 3 manual.
-For functions in the C library, this may be as follows:
-.Pp
-.D1 Standard C Library (libc, -lc)
-.It Em SYNOPSIS
-Documents the utility invocation syntax, function call syntax, or device
-configuration.
-.Pp
-For the first, utilities (sections 1, 6, and 8), this is
-generally structured as follows:
-.Pp
-.D1 \efBname\efR [-\efBab\efR] [-\efBc\efR\efIarg\efR] \efBpath\efR...
-.Pp
-For the second, function calls (sections 2, 3, 9):
-.Pp
-.D1 \&.B char *name(char *\efIarg\efR);
-.Pp
-And for the third, configurations (section 4):
-.Pp
-.D1 \&.B name* at cardbus ? function ?
-.Pp
-Manuals not in these sections generally don't need a
-.Em SYNOPSIS .
-.It Em DESCRIPTION
-This expands upon the brief, one-line description in
-.Em NAME .
-It usually contains a break-down of the options (if documenting a
-command).
-.It Em IMPLEMENTATION NOTES
-Implementation-specific notes should be kept here.
-This is useful when implementing standard functions that may have side
-effects or notable algorithmic implications.
-.It Em RETURN VALUES
-This section is the dual of
-.Em EXIT STATUS ,
-which is used for commands.
-It documents the return values of functions in sections 2, 3, and 9.
-.It Em ENVIRONMENT
-Documents any usages of environment variables, e.g.,
-.Xr environ 7 .
-.It Em FILES
-Documents files used.
-It's helpful to document both the file and a short description of how
-the file is used (created, modified, etc.).
-.It Em EXIT STATUS
-Command exit status for section 1, 6, and 8 manuals.
-This section is the dual of
-.Em RETURN VALUES ,
-which is used for functions.
-Historically, this information was described in
-.Em DIAGNOSTICS ,
-a practise that is now discouraged.
-.It Em EXAMPLES
-Example usages.
-This often contains snippets of well-formed,
-well-tested invocations.
-Make doubly sure that your examples work properly!
-.It Em DIAGNOSTICS
-Documents error conditions.
-This is most useful in section 4 manuals.
-Historically, this section was used in place of
-.Em EXIT STATUS
-for manuals in sections 1, 6, and 8; however, this practise is
-discouraged.
-.It Em ERRORS
-Documents error handling in sections 2, 3, and 9.
-.It Em SEE ALSO
-References other manuals with related topics.
-This section should exist for most manuals.
-.Pp
-.D1 \&.BR bar \&( 1 \&),

-.Pp
-.D1 IEEE Std 1003.2 (\e(lqPOSIX.2\e(rq)
-.Pp

-section should be used.
-.It Em HISTORY
-The history of any manual without a
-.Em STANDARDS

-.Sh MACRO SYNTAX
-Macros are one to three three characters in length and begin with a
-control character ,
-.Sq \&. ,
-at the beginning of the line.
-The
-.Sq \(aq
-macro control character is also accepted.
-An arbitrary amount of whitespace (spaces or tabs) may sit between the
-control character and the macro name.
-Thus, the following are equivalent:
-.Bd -literal -offset indent
-\&.PP
-\&.\ \ \ PP
-.Ed
-.Pp
-The
-.Nm
-macros are classified by scope: line scope or block scope.
-Line macros are only scoped to the current line (and, in some
-situations, the subsequent line).
-Block macros are scoped to the current line and subsequent lines until
-closed by another block macro.
-.Ss Line Macros
-Line macros are generally scoped to the current line, with the body
-consisting of zero or more arguments.
-If a macro is scoped to the next line and the line arguments are empty,
-the next line, which must be text, is used instead.
-Thus:
-.Bd -literal -offset indent
-\&.I
-foo
-.Ed
-.Pp
-is equivalent to
-.Sq \&.I foo .
-If next-line macros are invoked consecutively, only the last is used.
-If a next-line macro is followed by a non-next-line macro, an error is
-raised (unless in the case of
-.Sx \&br ,
-.Sx \&sp ,
-or
-.Sx \&na ) .
-.Pp
-The syntax is as follows:
-.Bd -literal -offset indent

-.Pp
-Macros marked as
-.Qq compat
-are included for compatibility with the significant corpus of existing
-manuals that mix dialects of roff.
-These macros should not be used for portable
-.Nm
-manuals.
-.Ss Block Macros
-Block macros are comprised of a head and body.
-Like for in-line macros, the head is scoped to the current line and, in
-one circumstance, the next line (the next-line stipulations as in
-.Sx Line Macros
-apply here as well).
-.Pp
-The syntax is as follows:
-.Bd -literal -offset indent
-\&.YO \(lBhead...\(rB
-\(lBhead...\(rB
-\(lBbody...\(rB
-.Ed
-.Pp
-The closure of body scope may be to the section, where a macro is closed
-by
-.Sx \&SH ;
-sub-section, closed by a section or
-.Sx \&SS ;
-part, closed by a section, sub-section, or
-.Sx \&RE ;
-or paragraph, closed by a section, sub-section, part,
-.Sx \&HP ,
-.Sx \&IP ,
-.Sx \&LP ,
-.Sx \&P ,
-.Sx \&PP ,
-or
-.Sx \&TP .
-No closure refers to an explicit block closing macro.
-.Pp
-As a rule, block macros may not be nested; thus, calling a block macro
-while another block macro scope is open, and the open scope is not
-implicitly closed, is syntactically incorrect.

-In quoted literals, GNU troff allowed pair-wise double-quotes to produce
-a standalone double-quote in formatted output.
-It is not known whether this behaviour is exhibited by other formatters.
-.It
-The
-.Sx \&sp
-macro does not accept negative values in mandoc.
-In GNU troff, this would result in strange behaviour.
-.It
-The
-.Sq \(aq
-macro control character, in GNU troff (and prior troffs) suppresses a
-newline before macro output; in mandoc, it is an alias for the standard
-.Sq \&.
