DESCRIPTION +The +.Nm +utility queries manual page databases generated by +.Xr mandocdb 8 , +evaluating on +.Ar expression +for each file in each database. +.Pp +By default, +.Nm +searches for +.Xr

operand +.Cm key +is an +.Xr mdoc 7 +macro to query and +.Cm val +is its value. +See +.Sx Macro Keys +for a list of available keys. +Operator +.Li \&= +evaluates a substring, while +.Li \&~ +evaluates a regular expression. +.It Fl i Ar term +If +.Ar term +is a regular expression, it +is evaluated case-insensitively. +Has no effect on substring terms. +.El +.Pp +Results are sorted by manual title,

-.Sh DESCRIPTION
-The
-.Nm
-library parses lines of
-.Xr man 7
-input into an abstract syntax tree (AST).
-.Pp
-In general, applications initiate a parsing sequence with
-.Fn man_alloc ,
-parse each line in a document with
-.Fn man_parseln ,
-close the parsing session with
-.Fn man_endparse ,
-operate over the syntax tree returned by
-.Fn man_node
-and
-.Fn man_meta ,
-then free all allocated memory with
-.Fn man_free .
-The
-.Fn man_reset
-function may be used in order to reset the parser for another input
-sequence.
-.Pp
-Beyond the full set of macros defined in
-.Xr man 7 ,
-the
-.Nm
-library also accepts the following macro:
-.Pp
-.Bl -tag -width Ds -compact
-.It PD
-Has no effect.
-Handled as a current-scope line macro.
-.El
-.Ss Types
-.Bl -ohang
-.It Vt struct man
-An opaque type.
-Its values are only used privately within the library.
-.It Vt struct man_node
-A parsed node.
-See
-.Sx Abstract Syntax Tree
-for details.
-.El
-.Ss Functions
-If
-.Fn man_addspan ,
-.Fn man_parseln ,
-or
-.Fn man_endparse
-return 0, calls to any function but
-.Fn man_reset
-or
-.Fn man_free
-will raise an assertion.
-.Bl -ohang
-.It Fn man_addspan
-Add a table span to the parsing stream.
-Returns 0 on failure, 1 on success.
-.It Fn man_alloc
-Allocates a parsing structure.
-The
-.Fa data
-pointer is passed to
-.Fa msgs .
-Always returns a valid pointer.
-The pointer must be freed with
-.Fn man_free .
-.It Fn man_reset
-Reset the parser for another parse routine.
-After its use,
-.Fn man_parseln
-behaves as if invoked for the first time.
-.It Fn man_free
-Free all resources of a parser.
-The pointer is no longer valid after invocation.
-.It Fn man_parseln
-Parse a nil-terminated line of input.
-This line should not contain the trailing newline.
-Returns 0 on failure, 1 on success.
-The input buffer
-.Fa buf
-is modified by this function.
-.It Fn man_endparse
-Signals that the parse is complete.
-Returns 0 on failure, 1 on success.
-.It Fn man_node
-Returns the first node of the parse.
-.It Fn man_meta
-Returns the document's parsed meta-data.
-.El
-.Ss Variables
-The following variables are also defined:
-.Bl -ohang
-.It Va man_macronames
-An array of string-ified token names.
-.El
-.Ss Abstract Syntax Tree
-The
-.Nm
-functions produce an abstract syntax tree (AST) describing input in a
-regular form.
-It may be reviewed at any time with
-.Fn man_nodes ;
-however, if called before
-.Fn man_endparse ,
-or after
-.Fn man_endparse
-or
-.Fn man_parseln
-fail, it may be incomplete.
-.Pp
-This AST is governed by the ontological rules dictated in
-.Xr man 7
-and derives its terminology accordingly.
-.Pp
-The AST is composed of
-.Vt struct man_node
-nodes with element, root and text types as declared by the
-.Va type
-field.
-Each node also provides its parse point (the
-.Va line ,
-.Va sec ,
-and
-.Va pos
-fields), its position in the tree (the
-.Va parent ,
-.Va child ,
-.Va next
-and
-.Va prev
-fields) and some type-specific data.
-.Pp
-The tree itself is arranged according to the following normal form,
-where capitalised non-terminals represent nodes.
-.Pp
-.Bl -tag -width "ELEMENTXX" -compact
-.It ROOT
-\(<- mnode+
-.It mnode
-\(<- ELEMENT | TEXT | BLOCK
-.It BLOCK
-\(<- HEAD BODY
-.It HEAD
-\(<- mnode*
-.It BODY
-\(<- mnode*
-.It ELEMENT
-\(<- ELEMENT | TEXT*
-.It TEXT
-\(<- [[:alpha:]]*
-.El
-.Pp
-The only elements capable of nesting other elements are those with
-next-lint scope as documented in
-.Xr man 7 .
-.Sh EXAMPLES
-The following example reads lines from stdin and parses them, operating
-on the finished parse tree with
-.Fn parsed .
-This example does not error-check nor free memory upon failure.
-.Bd -literal -offset indent

 .Sh NAME
 .Nm man
-.Nd man language reference
+.Nd legacy formatting language for manual pages
 .Sh DESCRIPTION
-The
+Traditionally, the
 .Nm man
-language was historically used to format
+language has been used to write
 .Ux
-manuals.
-This reference document describes its syntax, structure, and usage.
+manuals for the
+.Xr man 1
+utility.
+It supports limited control of presentational details like fonts,
+indentation and spacing.
+This reference document describes the structure of manual pages
+and the syntax and usage of the man language.
 .Pp
 .Bf -emphasis
 Do not use
 .Nm
-to write your manuals.
+to write your manuals:
 .Ef
+It lacks support for semantic markup.
 Use the
 .Xr mdoc 7
 language, instead.
 .Pp
-A
+In a
 .Nm
-document follows simple rules:  lines beginning with the control
-character
+document, lines beginning with the control character
 .Sq \&.
-are parsed for macros.
-Other lines are interpreted within the scope of
-prior macros:
+are called
+.Dq macro lines .
+The first word is the macro name.
+It usually consists of two capital letters.
+For a list of available macros, see
+.Sx MACRO OVERVIEW .
+The words following the macro name are arguments to the macro.
+.Pp
+Lines not beginning with the control character are called
+.Dq text lines .
+They provide free-form text to be printed; the formatting of the text
+depends on the respective processing context:
 .Bd -literal -offset indent
 \&.SH Macro lines change control state.
-Other lines are interpreted within the current state.
+Text 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 tab 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\*q ,
-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\*q ,
-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
-The
-.Sq \ef
-attribute is 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; unescaped
-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
+Many aspects of the basic syntax of the
 .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 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

-Macros are one to 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:

-.Pp
-The

-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:

-.Ss Block Macros
-Block macros comprise a head and body.

+.Sh MACRO SYNTAX
+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, except for
+.Sx \&br ,
+.Sx \&sp ,
+and
+.Sx \&na .

+.Ss Block Macros
+Block macros comprise a head and body.
+As with 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.CGI 7
+.Os
+.Sh NAME
+.Nm man.cgi
+.Nd cgi for manpage query and display
+.Sh SYNOPSIS
+.Nm
+.Sh DESCRIPTION
+The
+.Nm
+script queries and displays manual pages.
+It interfaces with
+.Xr mandocdb 8
+databases cached with
+.Xr catman 8 .
+.Pp
+To use
+.Nm ,
+create a manual cache in
+.Xr catman 8 .
+Assign this directory to the environment variable
+.Ev CACHE_DIR ,
+defaulting to
+.Pa /cache/man.cgi .
+Copy the
+.Pa man.cgi
+script into your CGI directory (see
+.Sx FILES
+for other relevant files).
+.Pp
+Multiple
+.Xr catman 8
+trees may be managed by
+.Nm :
+directories under
+.Ev CACHE_DIR
+containing
+.Pa etc/catman.conf
+are identified as
+.Qq manroots .
+The path of a manroot under
+.Ev CACHE_DIR
+is converted to a name by replacing path separators with spaces.
+.Pp
+Thus, if
+.Ev CACHE_DIR
+is the default
+.Pa /cache/man.cgi ,
+the web-server is jailed to
+.Pa /var/www ,
+and cache subdirectories
+.Pa ./foo/1
+and
+.Pa ./bar/2
+contain
+.Pa etc/catman.conf ,
+.Nm
+will assign these to manroots
+.Qq foo 1
+and
+.Qq bar 2 ,
+respectively.
+These names will appear as choices when searching for manuals.
+.Pp
+If
+.Nm
+finds only one manroot, or none, then the selection box is omitted.
+If no manroot is specified during search, the first manroot is used by
+default.
+.Sh ENVIRONMENT
+.Bl -tag -width Ds
+.It Ev CACHE_DIR
+The absolute path of the
+.Xr catman 8
+cache directory.
+This must not have a trailing slash.
+.It Ev CSS_DIR
+Prepended to CSS file links in outputted HTML files.
+This must not have a trailing slash.
+.El
+.Sh FILES
+.Bl -tag -width Ds
+.It Pa etc/catman.conf
+Built by
+.Xr catman 8
+and must exist at least once under the configuration directory root.
+.It Pa man.css
+Should be visible in the server document root or within
+.Ev CSS_DIR .
+Included in each page after
+.Pa man-cgi.css , 
+ostensibly for
+.Xr mandoc 1
+HTML output styling.
+.It Pa man.cgi.css
+Should be visible in the server document root or within
+.Ev CSS_DIR .
+Included in each page, ostensibly for general
+.Nm
+styling.
+.El
+.Sh COMPATIBILITY
+The
+.Nm
+script is call-compatible with queries from the traditional
+.Pa man.cgi
+script by Wolfram Schneider.
+However, the results may not be quite the same.
+.Sh SEE ALSO
+.Xr catman 8 ,
+.Xr mandocdb 8
+.Sh AUTHORS
+The
+.Nm
+utility was written by
+.An Kristaps Dzonsons ,
+.Mt kristaps@bsd.lv .
+.Sh CAVEATS
+If you're running in a jailed web-server, make sure the
+.Pa /tmp
+directory exists and is writable.
+The databases may need this for scratch space.

+.El
+.Ss Functions
+.Bl -ohang
+.It Fn mandoc_escape
+Scan an escape sequence, i.e., a character string beginning with

+If not
+.Dv ESCAPE_ERROR
+or
+.Dv ESCAPE_IGNORE ,
+.Va start
+is set to the first relevant character of the substring (font, glyph,

+.Sh IMPLEMENTATION NOTES
+This section consists of structural documentation for
+.Xr mdoc 7
+and
+.Xr man 7
+syntax trees and strings.
+.Ss Man and Mdoc Strings
+Strings may be extracted from mdoc and man meta-data, or from text
+nodes (MDOC_TEXT and MAN_TEXT, respectively).
+These strings have special non-printing formatting cues embedded in the
+text itself, as well as
+.Xr roff 7
+escapes preserved from input.
+Implementing systems will need to handle both situations to produce
+human-readable text.
+In general, strings may be assumed to consist of 7-bit ASCII characters.
+.Pp
+The following non-printing characters may be embedded in text strings:
+.Bl -tag -width Ds
+.It Dv ASCII_NBRSP
+A non-breaking space character.
+.It Dv ASCII_HYPH
+A soft hyphen.
+.El
+.Pp
+Escape characters are also passed verbatim into text strings.
+An escape character is a sequence of characters beginning with the
+backslash
+.Pq Sq \e .
+To construct human-readable text, these should be intercepted with
+.Fn mandoc_escape
+and converted with one of
+.Fn mchars_num2char ,
+.Fn mchars_spec2str ,
+and so on.
+.Ss Man Abstract Syntax Tree
+This AST is governed by the ontological rules dictated in
+.Xr man 7
+and derives its terminology accordingly.
+.Pp
+The AST is composed of
+.Vt struct man_node
+nodes with element, root and text types as declared by the
+.Va type
+field.
+Each node also provides its parse point (the
+.Va line ,
+.Va sec ,
+and
+.Va pos
+fields), its position in the tree (the
+.Va parent ,
+.Va child ,
+.Va next
+and
+.Va prev
+fields) and some type-specific data.
+.Pp
+The tree itself is arranged according to the following normal form,
+where capitalised non-terminals represent nodes.

+.El
+.Pp
+The only elements capable of nesting other elements are those with
+next-lint scope as documented in
+.Xr man 7 .
+.Ss Mdoc Abstract Syntax Tree
+This AST is governed by the ontological
+rules dictated in
+.Xr mdoc 7
+and derives its terminology accordingly.
+.Qq In-line
+elements described in
+.Xr mdoc 7
+are described simply as
+.Qq elements .
+.Pp
+The AST is composed of
+.Vt struct mdoc_node
+nodes with block, head, body, element, root and text types as declared
+by the
+.Va type
+field.
+Each node also provides its parse point (the
+.Va line ,
+.Va sec ,
+and
+.Va pos
+fields), its position in the tree (the
+.Va parent ,
+.Va child ,
+.Va nchild ,
+.Va next
+and
+.Va prev
+fields) and some type-specific data, in particular, for nodes generated
+from macros, the generating macro in the
+.Va tok
+field.
+.Pp
+The tree itself is arranged according to the following normal form,
+where capitalised non-terminals represent nodes.
+.Pp
+.Bl -tag -width "ELEMENTXX" -compact

+.It TAIL
+\(<- mnode*
+.It TEXT
+\(<- [[:ascii:]]*
+.El
+.Pp
+Of note are the TEXT nodes following the HEAD, BODY and TAIL nodes of
+the BLOCK production: these refer to punctuation marks.
+Furthermore, although a TEXT node will generally have a non-zero-length
+string, in the specific case of
+.Sq \&.Bd \-literal ,
+an empty line will produce a zero-length string.
+Multiple body parts are only found in invocations of
+.Sq \&Bl \-column ,
+where a new body introduces a new phrase.
+.Pp
+The
+.Xr mdoc 7
+syntax tree accommodates for broken block structures as well.
+The ENDBODY node is available to end the formatting associated
+with a given block before the physical end of that block.
+It has a non-null
+.Va end
+field, is of the BODY
+.Va type ,
+has the same
+.Va tok
+as the BLOCK it is ending, and has a
+.Va pending
+field pointing to that BLOCK's BODY node.
+It is an indirect child of that BODY node
+and has no children of its own.
+.Pp
+An ENDBODY node is generated when a block ends while one of its child
+blocks is still open, like in the following example:
+.Bd -literal -offset indent
+\&.Ao ao
+\&.Bo bo ac
+\&.Ac bc
+\&.Bc end
+.Ed
+.Pp
+This example results in the following block structure:

+Support for badly-nested blocks is only provided for backward

+implementations.
+Using badly-nested blocks is
+.Em strongly discouraged ;

+.Fl T Ns Cm xhtml
+front-ends to
+.Xr mandoc 1
+are unable to render them in any meaningful way.
+Furthermore, behaviour when encountering badly-nested blocks is not
+consistent across troff implementations, especially when using  multiple

 .Os
 .Sh NAME
 .Nm mandoc_char
 .Nd mandoc special characters
 .Sh DESCRIPTION
-This page documents the special characters and predefined strings accepted by
+This page documents the
+.Xr roff 7
+escape sequences accepted by
 .Xr mandoc 1
-to format
+to represent special characters in
 .Xr mdoc 7
 and
 .Xr man 7
 documents.
 .Pp
-Both
-.Xr mdoc 7
-and
-.Xr man 7
-encode special characters with
+The rendering depends on the
+.Xr mandoc 1
+output mode; in ASCII output, most characters are completely
+unintelligible.
+For that reason, using any of the special characters documented here,
+except those discussed in the
+.Sx DESCRIPTION ,
+is strongly discouraged; they are supported merely for backwards
+compatibility with existing documents.
+.Pp
+In particular, in English manual pages, do not use special-character
+escape sequences to represent national language characters in author
+names; instead, provide ASCII transcriptions of the names.
+.Ss Dashes and Hyphens
+In typography there are different types of dashes of various width:
+the hyphen (-),
+the minus sign (\-),
+the en-dash (\(en),
+and the em-dash (\(em).
+.Pp
+Hyphens are used for adjectives;
+to separate the two parts of a compound word;
+or to separate a word across two successive lines of text.
+The hyphen does not need to be escaped:
+.Bd -unfilled -offset indent
+blue-eyed
+lorry-driver
+.Ed
+.Pp
+The mathematical minus sign is used for negative numbers or subtraction.
+It should be written as
+.Sq \e- :
+.Bd -unfilled -offset indent
+a = 3 \e- 1;
+b = \e-2;
+.Ed
+.Pp
+The en-dash is used to separate the two elements of a range,
+or can be used the same way as an em-dash.
+It should be written as
+.Sq \e(en :
+.Bd -unfilled -offset indent
+pp. 95\e(en97.
+Go away \e(en or else!
+.Ed
+.Pp
+The em-dash can be used to show an interruption
+or can be used the same way as colons, semi-colons, or parentheses.
+It should be written as
+.Sq \e(em :
+.Bd -unfilled -offset indent
+Three things \e(em apples, oranges, and bananas.
+This is not that \e(em rather, this is that.
+.Ed
+.Pp
+Note:
+hyphens, minus signs, and en-dashes look identical under normal ASCII output.
+Other formats, such as PostScript, render them correctly,
+with differing widths.
+.Ss Spaces
+To separate words in normal text, for indenting and alignment
+in literal context, and when none of the following special cases apply,
+just use the normal space character
+.Pq Sq \  .
+.Pp
+When filling text, lines may be broken between words, i.e. at space
+characters.
+To prevent a line break between two particular words,
+use the non-breaking space escape sequence
+.Pq Sq \e~
+instead of the normal space character.
+For example, the input string
+.Dq number\e~1
+will be kept together as
+.Dq number\~1
+on the same output line.
+.Pp
+On request and macro lines, the normal space character serves as an
+argument delimiter.
+To include whitespace into arguments, quoting is usually the best choice.
+In some cases, using either the non-breaking
+.Pq Sq \e~
+or the breaking
+.Pq Sq \e\ \&
+space escape sequence may be preferable.
+To escape macro names and to protect whitespace at the end
+of input lines, the zero-width space
+.Pq Sq \e&
+is often useful.
+For example, in
+.Xr mdoc 7 ,
+a normal space character can be displayed in single quotes in either
+of the following ways:
+.Pp
+.Dl .Sq \(dq \(dq
+.Dl .Sq \e \e&
+.Ss Quotes
+On request and macro lines, the double-quote character
+.Pq Sq \(dq
+is handled specially to allow quoting.
+One way to prevent this special handling is by using the
+.Sq \e(dq
+escape sequence.
+.Pp
+Note that on text lines, literal double-quote characters can be used
+verbatim.
+All other quote-like characters can be used verbatim as well,
+even on request and macro lines.
+.Ss Periods
+The period
+.Pq Sq \&.
+is handled specially at the beginning of an input line,
+where it introduces a
+.Xr roff 7
+request or a macro, and when appearing alone as a macro argument in
+.Xr mdoc 7 .
+In such situations, prepend a zero-width space
+.Pq Sq \e&.
+to make it behave like normal text.
+.Pp
+Do not use the
+.Sq \e.
+escape sequence.
+It does not prevent special handling of the period.
+.Ss Backslashes
+To include a literal backslash
+.Pq Sq \e
+into the output, use the
+.Pq Sq \ee
+escape sequence.
+.Pp
+Note that doubling it
+.Pq Sq \e\e
+is not the right way to output a backslash.
+Because
+.Xr mandoc 1
+does not implement full
+.Xr roff 7
+functionality, it may work with
+.Xr mandoc 1 ,
+but it may have weird effects on complete
+.Xr roff 7
+implementations.

+The time to construct a new database pair grows linearly with the
+number of keywords in the input files.
+However, removing or updating entries with
+.Fl u
+or
+.Fl d ,
+respectively, grows as a multiple of the index length and input size.

+.It 0
+No errors occurred.
+.It 5
+Invalid command line arguments were specified.
+No input files have been read.
+.It 6
+An operating system error occurred, for example memory exhaustion or an
+error accessing input files.
+Such errors cause
+.Nm
+to exit at once, possibly in the middle of parsing or formatting a file.
+The output databases are corrupt and should be removed.

+.It "%s: Path too long"
+The file
+.Pa %s

-.Sh DESCRIPTION
-The
-.Nm mdoc
-library parses lines of
-.Xr mdoc 7
-input
-into an abstract syntax tree (AST).
-.Pp
-In general, applications initiate a parsing sequence with
-.Fn mdoc_alloc ,
-parse each line in a document with
-.Fn mdoc_parseln ,
-close the parsing session with
-.Fn mdoc_endparse ,
-operate over the syntax tree returned by
-.Fn mdoc_node
-and
-.Fn mdoc_meta ,
-then free all allocated memory with
-.Fn mdoc_free .
-The
-.Fn mdoc_reset
-function may be used in order to reset the parser for another input
-sequence.
-.Ss Types
-.Bl -ohang
-.It Vt struct mdoc
-An opaque type.
-Its values are only used privately within the library.
-.It Vt struct mdoc_node
-A parsed node.
-See
-.Sx Abstract Syntax Tree
-for details.
-.El
-.Ss Functions
-If
-.Fn mdoc_addspan ,
-.Fn mdoc_parseln ,
-or
-.Fn mdoc_endparse
-return 0, calls to any function but
-.Fn mdoc_reset
-or
-.Fn mdoc_free
-will raise an assertion.
-.Bl -ohang
-.It Fn mdoc_addspan
-Add a table span to the parsing stream.
-Returns 0 on failure, 1 on success.
-.It Fn mdoc_alloc
-Allocates a parsing structure.
-The
-.Fa data
-pointer is passed to
-.Fa msgs .
-Always returns a valid pointer.

-.Ss Abstract Syntax Tree
-The
-.Nm
-functions produce an abstract syntax tree (AST) describing input in a
-regular form.
-It may be reviewed at any time with
-.Fn mdoc_nodes ;
-however, if called before
-.Fn mdoc_endparse ,
-or after
-.Fn mdoc_endparse
-or
-.Fn mdoc_parseln
-fail, it may be incomplete.
-.Pp
-This AST is governed by the ontological
-rules dictated in
-.Xr mdoc 7
-and derives its terminology accordingly.
-.Qq In-line
-elements described in
-.Xr mdoc 7
-are described simply as
-.Qq elements .
-.Pp
-The AST is composed of
-.Vt struct mdoc_node
-nodes with block, head, body, element, root and text types as declared
-by the
-.Va type
-field.
-Each node also provides its parse point (the
-.Va line ,
-.Va sec ,
-and
-.Va pos
-fields), its position in the tree (the
-.Va parent ,
-.Va child ,
-.Va nchild ,
-.Va next
-and
-.Va prev
-fields) and some type-specific data, in particular, for nodes generated
-from macros, the generating macro in the
-.Va tok
-field.
-.Pp
-The tree itself is arranged according to the following normal form,
-where capitalised non-terminals represent nodes.
-.Pp
-.Bl -tag -width "ELEMENTXX" -compact
-.It ROOT
-\(<- mnode+
-.It mnode
-\(<- BLOCK | ELEMENT | TEXT
-.It BLOCK
-\(<- HEAD [TEXT] (BODY [TEXT])+ [TAIL [TEXT]]
-.It ELEMENT
-\(<- TEXT*
-.It HEAD
-\(<- mnode*
-.It BODY
-\(<- mnode* [ENDBODY mnode*]
-.It TAIL
-\(<- mnode*
-.It TEXT
-\(<- [[:printable:],0x1e]*
-.El
-.Pp
-Of note are the TEXT nodes following the HEAD, BODY and TAIL nodes of
-the BLOCK production: these refer to punctuation marks.
-Furthermore, although a TEXT node will generally have a non-zero-length
-string, in the specific case of
-.Sq \&.Bd \-literal ,
-an empty line will produce a zero-length string.
-Multiple body parts are only found in invocations of
-.Sq \&Bl \-column ,
-where a new body introduces a new phrase.
-.Ss Badly-nested Blocks
-The ENDBODY node is available to end the formatting associated
-with a given block before the physical end of that block.
-It has a non-null
-.Va end
-field, is of the BODY
-.Va type ,
-has the same
-.Va tok
-as the BLOCK it is ending, and has a
-.Va pending
-field pointing to that BLOCK's BODY node.
-It is an indirect child of that BODY node
-and has no children of its own.
-.Pp
-An ENDBODY node is generated when a block ends while one of its child
-blocks is still open, like in the following example:
-.Bd -literal -offset indent
-\&.Ao ao
-\&.Bo bo ac
-\&.Ac bc
-\&.Bc end
-.Ed
-.Pp
-This example results in the following block structure:
-.Bd -literal -offset indent
-BLOCK Ao
-	HEAD Ao
-	BODY Ao
-		TEXT ao
-		BLOCK Bo, pending -> Ao
-			HEAD Bo
-			BODY Bo
-				TEXT bo
-				TEXT ac
-				ENDBODY Ao, pending -> Ao
-				TEXT bc
-TEXT end
-.Ed
-.Pp
-Here, the formatting of the
-.Sq \&Ao
-block extends from TEXT ao to TEXT ac,
-while the formatting of the
-.Sq \&Bo
-block extends from TEXT bo to TEXT bc.
-It renders as follows in
-.Fl T Ns Cm ascii
-mode:
-.Pp
-.Dl <ao [bo ac> bc] end
-.Pp
-Support for badly-nested blocks is only provided for backward
-compatibility with some older
-.Xr mdoc 7
-implementations.
-Using badly-nested blocks is
-.Em strongly discouraged :
-the
-.Fl T Ns Cm html
-and
-.Fl T Ns Cm xhtml
-front-ends are unable to render them in any meaningful way.
-Furthermore, behaviour when encountering badly-nested blocks is not
-consistent across troff implementations, especially when using  multiple
-levels of badly-nested blocks.
-.Sh EXAMPLES
-The following example reads lines from stdin and parses them, operating
-on the finished parse tree with
-.Fn parsed .
-This example does not error-check nor free memory upon failure.

 .Sh NAME
 .Nm mdoc
-.Nd mdoc language reference
+.Nd semantic markup language for formatting manual pages
 .Sh DESCRIPTION
 The
 .Nm mdoc
-language is used to format
-.Bx
-.Ux
-manuals.
-This reference document describes its syntax, structure, and
-usage.
-The reference implementation is
+language supports authoring of manual pages for the
+.Xr man 1
+utility by allowing semantic annotations of words, phrases,
+page sections and complete manual pages.
+Such annotations are used by formatting tools to achieve a uniform
+presentation across all manuals written in
+.Nm ,
+and to support hyperlinking if supported by the output medium.
+.Pp
+This reference document describes the structure of manual pages
+and the syntax and usage of the
+.Nm
+language.
+The reference implementation of a parsing and formatting tool is
 .Xr mandoc 1 ;
 the
 .Sx COMPATIBILITY
-section describes compatibility with other troff \-mdoc implementations.
+section describes compatibility with other implementations.
 .Pp
-An
+In 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:
+document, lines beginning with the control character
+.Sq \&.
+are called
+.Dq macro lines .
+The first word is the macro name.
+It consists of two or three letters.
+Most macro names begin with a capital letter.
+For a list of available macros, see
+.Sx MACRO OVERVIEW .
+The words following the macro name are arguments to the macro, optionally
+including the names of other, callable macros; see
+.Sx MACRO SYNTAX
+for details.
+.Pp
+Lines not beginning with the control character are called
+.Dq text lines .
+They provide free-form text to be printed; the formatting of the text
+depends on the respective processing context:
 .Bd -literal -offset indent
 \&.Sh Macro lines change control state.
-Other lines are interpreted within the current state.
+Text lines are interpreted within the current state.
 .Ed
-.Sh LANGUAGE SYNTAX
-.Nm
-documents may contain only graphable 7-bit ASCII characters, the space
-character, and, in certain circumstances, the tab character.
-All manuals must have
-.Ux
-line terminators.
-.Ss Comments
-Text following a
-.Sq \e\*q ,
-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\*q ,
-is also ignored.
-Macro lines with only a control character and optional whitespace are
-stripped from input.
-.Ss Reserved Characters
-Within a macro line, the following characters are reserved:
-.Pp
-.Bl -tag -width Ds -offset indent -compact
-.It \&.
-.Pq period
-.It \&,
-.Pq comma
-.It \&:
-.Pq colon
-.It \&;
-.Pq semicolon
-.It \&(
-.Pq left-parenthesis
-.It \&)
-.Pq right-parenthesis
-.It \&[
-.Pq left-bracket
-.It \&]
-.Pq right-bracket
-.It \&?
-.Pq question
-.It \&!
-.Pq exclamation
-.It \&|
-.Pq vertical bar
-.El
-.Pp
-Use of reserved characters is described in
-.Sx MACRO SYNTAX .
-For general use in macro lines, these characters can either be escaped
-with a non-breaking space
-.Pq Sq \e&
-or, if applicable, an appropriate escape sequence can be used.
-.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
-.Dl \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 valid within
-the current font scope only: if a macro opens a font scope alongside
-its own scope, such as
-.Sx \&Bf
-.Cm \&Sy ,
-in-scope invocations of
-.Sq \ef
-are only valid within the font scope of the macro.
-If
-.Sq \ef
-is specified outside of any font scope, such as in unenclosed, free-form
-text, it will affect the remainder of the document.
 .Pp
-Note this form is
-.Em not
-recommended for
-.Nm ,
-which encourages semantic annotation.
-.Ss Predefined Strings
-Historically,
-troff
-also defined a set of package-specific
-.Dq predefined strings ,
-which, like
-.Sx Special Characters ,
-mark special output characters and strings by way of input codes.
-Predefined strings are escaped with the slash-asterisk,
-.Sq \e* :
-single-character
-.Sq \e*X ,
-two-character
-.Sq \e*(XX ,
-and N-character
-.Sq \e*[N] .
-See
-.Xr mandoc_char 7
-for a complete list.
-Examples include
-.Sq \e*(Am
-.Pq ampersand
+Many aspects of the basic syntax of the
+.Nm
+language are based on the
+.Xr roff 7
+language; see the
+.Em LANGUAGE SYNTAX
 and
-.Sq \e*(Ba
-.Pq vertical bar .
-.Ss Whitespace
-Whitespace consists of the space character.
-In free-form lines, whitespace is preserved within a line; unescaped
-trailing spaces are stripped from input (unless in a literal context).
-Blank free-form lines, which may include whitespace, are only permitted
-within literal contexts.
-.Pp
-In macro lines, whitespace delimits arguments and is discarded.
-If arguments are quoted, whitespace within the quotes is retained.
-.Ss Quotation
-Macro arguments may be quoted with double-quotes to group
-space-delimited terms or to retain blocks of whitespace.
-A quoted argument begins with a double-quote preceded by whitespace.
-The next double-quote not pairwise adjacent to another double-quote
-terminates the literal, regardless of surrounding whitespace.
-.Pp
-Note that any quoted text, even if it would cause a macro invocation
-when unquoted, is considered literal text.
-Thus, the following produces
-.Sq Op "Fl a" :
-.Bd -literal -offset indent
-\&.Op "Fl a"
-.Ed
-.Pp
-In free-form mode, quotes are regarded as opaque text.
-.Ss Dates
-There are several macros in
+.Em MACRO SYNTAX
+sections in the
+.Xr roff 7
+manual for details, in particular regarding
+comments, escape sequences, whitespace, and quoting.
+However, using
+.Xr roff 7
+requests in
 .Nm
-that require a date argument.
-The canonical form for dates is the American format:
-.Pp
-.D1 Cm Month Day , Year
-.Pp
-The
-.Cm Day
-value is an optionally zero-padded numeral.
-The
-.Cm Month
-value is the full month name.
-The
-.Cm Year
-value is the full four-digit year.
-.Pp
-Reduced form dates are broken-down canonical form dates:
-.Pp
-.D1 Cm Month , Year
-.D1 Cm Year
-.Pp
-Some examples of valid dates follow:
-.Pp
-.D1 "May, 2009" Pq reduced form
-.D1 "2009" Pq reduced form
-.D1 "May 20, 2009" Pq canonical form
-.Ss Scaling Widths
-Many macros support scaled widths for their arguments, such as
-stipulating a two-inch list indentation with the following:
-.Bd -literal -offset indent
-\&.Bl -tag -width 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.
-See
-.Sx COMPATIBILITY .
-.Ss Sentence Spacing
-When composing a manual, make sure that 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 \&" ) .
-.Pp
-The proper spacing is also intelligently preserved if a sentence ends at
-the boundary of a macro line.
-For example:
-.Pp
-.Dl \&Xr mandoc 1 \.
-.Dl \&Fl T \&Ns \&Cm ascii \.
+documents is discouraged;
+.Xr mandoc 1
+supports some of them merely for backward compatibility.

-The syntax of a macro depends on its classification.
-In this section,
-.Sq \-arg
-refers to macro arguments, which may be followed by zero or more
-.Sq parm
-parameters;
-.Sq \&Yo
-opens the scope of a macro; and if specified,
-.Sq \&Yc
-closes it out.
+Examples:
+.Dl \&.Ad [0,$]
+.Dl \&.Ad 0x00000000
+.Ss \&An
+Author name.
+Can be used both for the authors of the program, function, or driver
+documented in the manual, or for the authors of the manual itself.
+Requires either the name of an author or one of the following arguments:
 .Pp
-The
-.Em Callable
-column indicates that the macro may also be called by passing its name
-as an argument to another macro.
-If a macro is not callable but its name appears as an argument
-to another macro, it is interpreted as opaque text.
-For example,
-.Sq \&.Fl \&Sh
-produces
-.Sq Fl \&Sh .
+.Bl -tag -width "-nosplitX" -offset indent -compact
+.It Fl split
+Start a new output line before each subsequent invocation of
+.Sx \&An .
+.It Fl nosplit
+The opposite of
+.Fl split .
+.El
 .Pp
-The
-.Em Parsed
-column indicates whether the macro may call other macros by receiving
-their names as arguments.
-If a macro is not parsed but the name of another macro appears
-as an argument, it is interpreted as opaque text.
+The default is
+.Fl nosplit .
+The effect of selecting either of the
+.Fl split
+modes ends at the beginning of the
+.Em AUTHORS
+section.
+In the
+.Em AUTHORS
+section, the default is
+.Fl nosplit
+for the first author listing and
+.Fl split
+for all other author listings.
 .Pp
-The
-.Em Scope
-column, if applicable, describes closure rules.

+.Sh MACRO SYNTAX
+The syntax of a macro depends on its classification.
+In this section,
+.Sq \-arg
+refers to macro arguments, which may be followed by zero or more
+.Sq parm
+parameters;
+.Sq \&Yo
+opens the scope of a macro; and if specified,
+.Sq \&Yc
+closes it out.
+.Pp
+The
+.Em Callable
+column indicates that the macro may also be called by passing its name
+as an argument to another macro.
+For example,
+.Sq \&.Op \&Fl O \&Ar file
+produces
+.Sq Op Fl O Ar file .
+To prevent a macro call and render the macro name literally,
+escape it by prepending a zero-width space,
+.Sq \e& .
+For example,
+.Sq \&Op \e&Fl O
+produces
+.Sq Op \&Fl O .
+If a macro is not callable but its name appears as an argument
+to another macro, it is interpreted as opaque text.
+For example,
+.Sq \&.Fl \&Sh
+produces
+.Sq Fl \&Sh .
+.Pp
+The
+.Em Parsed
+column indicates whether the macro may call other macros by receiving
+their names as arguments.
+If a macro is not parsed but the name of another macro appears
+as an argument, it is interpreted as opaque text.
+.Pp
+The
+.Em Scope
+column, if applicable, describes closure rules.
+.Ss Block full-explicit
+Multi-line scope closed by an explicit closing macro.
+All macros contains bodies; only
+.Sx \&Bf
+and
+.Pq optionally

+.Ss Delimiters
+When a macro argument consists of one single input character
+considered as a delimiter, the argument gets special handling.
+This does not apply when delimiters appear in arguments containing
+more than one character.
+Consequently, to prevent special handling and just handle it
+like any other argument, a delimiter can be escaped by prepending
+a zero-width space
+.Pq Sq \e& .
+In text lines, delimiters never need escaping, but may be used
+as normal punctuation.
+.Pp
+For many macros, when the leading arguments are opening delimiters,
+these delimiters are put before the macro scope,
+and when the trailing arguments are closing delimiters,
+these delimiters are put after the macro scope.
+For example,
 .Pp

+and also to the middle delimiter:
 .Pp
-.D1 Pf \. Sx \&sp Op Cm height
+.Bl -tag -width Ds -offset indent -compact
+.It \&|
+vertical bar
+.El
 .Pp
-The
-.Cm height
-argument must be formatted as described in
-.Sx Scaling Widths .
-If unspecified,
-.Sx \&sp
-asserts a single vertical space.
+As a special case, the predefined string \e*(Ba is handled and rendered
+in the same way as a plain
+.Sq \&|
+character.
+Using this predefined string is not recommended in new manuals.
+.Ss Font handling
+In
+.Nm
+documents, usage of semantic markup is recommended in order to have
+proper fonts automatically selected; only when no fitting semantic markup
+is available, consider falling back to
+.Sx Physical markup
+macros.
+Whenever any
+.Nm
+macro switches the
+.Xr roff 7
+font mode, it will automatically restore the previous font when exiting
+its scope.
+Manually switching the font using the

+.Ql \ef
+font escape sequences is never required.

+Its arguments are as follows:
+.Bl -tag -width Ds
+.It Fl D Ar enc
+The default encoding.
+.It Fl e Ar enc
+The document's encoding.
+.It Ar file
+The input file.
+.El
+.Pp
+The recoded input is written to standard output: Unicode characters in
+the ASCII range are printed as regular ASCII characters, while those
+above this range are printed using the
+.Sq \e[uNNNN]
+format documented in
+.Xr mandoc_char 7 .
+.Pp
+If input bytes are improperly formed in the current encoding, they're
+passed unmodified to standard output.
+For some encodings, such as UTF-8, unrecoverable input sequences will
+cause
+.Nm
+to stop processing and exit.
+.Ss Algorithm
+An encoding is chosen according to the following steps:
+.Bl -enum
+.It
+From the argument passed to
+.Fl e Ar enc .
+.It
+If a BOM exists, UTF\-8 encoding is selected.
+.It
+From the coding tags parsed from
+.Qq File Variables
+on the first two lines of input.
+A file variable is an input line of the form
+.Pp
+.Dl \%.\e\(dq -*- key: val [; key: val ]* -*-
+.Pp
+A coding tag variable is where
+.Cm key
+is
+.Qq coding
+and
+.Cm val
+is the name of the encoding.
+A typical file variable with a coding tag is
+.Pp
+.Dl \%.\e\(dq -*- mode: troff; coding: utf-8 -*-
+.It
+From the argument passed to
+.Fl D Ar enc .
+.It
+If all else fails, Latin\-1 is used.
+.El
+.Pp
+The
+.Nm
+utility recognises the UTF\-8, us\-ascii, and latin\-1 encodings as
+passed to the
+.Fl e
+and
+.Fl D
+arguments, or as coding tags.
+Encodings are matched case-insensitively.

-.Fn roff_free .
-The
-.Fn roff_reset
-function may be used in order to reset the parser for another input
-sequence.
-.Pp
-The
-.Fn roff_parseln
-function should be invoked before passing a line into the
-.Xr mdoc 3
-or
-.Xr man 3
-libraries.

-behaves as if invoked for the first time.
-.It Fn roff_free
-Free all resources of a parser.
-The pointer is no longer valid after invocation.
-.It Fn roff_parseln
-Parse a nil-terminated line of input.
-The character array
-.Fa bufp

 The

 language is a general purpose text formatting language.

+many real-world manuals use small numbers of
 .Nm
-language accepted by the

+.Xr mdoc 7
+or
+.Xr man 7

+To properly format such manuals, the
+.Xr mandoc 1

+.Nm
+requests.
+Only these requests supported by
 .Xr mandoc 1
-utility.
+are documented in the present manual,
+together with the basic language syntax shared by

-Some requests and macros also produce formatted output,
-while others do not.

-All other input lines provide free-form text to be printed;

 documents may contain only graphable 7-bit ASCII characters, the space
 character, and, in certain circumstances, the tab character.
-To produce other characters in the output, use the escape sequences
-documented in the
+The back-space character
+.Sq \e
+indicates the start of an escape sequence for
+.Sx Comments ,
+.Sx Special Characters ,
+.Sx Predefined Strings ,

+.Ss Comments
+Text following an escaped double-quote
+.Sq \e\(dq ,
+whether in a request, macro, or text line, is ignored to the end of the line.
+A request line beginning with a control character and comment escape
+.Sq \&.\e\(dq
+is also ignored.
+Furthermore, request lines with only a control character and optional
+trailing whitespace are stripped from input.
+.Pp
+Examples:
+.Bd -literal -offset indent -compact
+\&.\e\(dq This is a comment line.
+\&.\e\(dq The next line is ignored:
+\&.
+\&.Sh EXAMPLES \e\(dq This is a comment, too.
+\&example text \e\(dq And so is this.
+.Ed
+.Ss Special Characters
+Special characters are used to encode special glyphs and are rendered
+differently across output media.
+They may occur in request, macro, and text 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.

+Terms may be text-decorated using the
+.Sq \ef
+escape followed by an indicator: B (bold), I (italic), R (regular), or P
+(revert to previous mode).
+A numerical representation 3, 2, or 1 (bold, italic, and regular,
+respectively) may be used instead.
+The indicator or numerical representative may be preceded by C
+(constant-width), which is ignored.
+.Pp
+Examples:
+.Bl -tag -width Ds -offset indent -compact
+.It Li \efBbold\efR
+Write in bold, then switch to regular font mode.
+.It Li \efIitalic\efP
+Write in italic, then return to previous font mode.
+.El
 .Pp
-All manuals must have
-.Ux
-line terminators.
+Text decoration is
+.Em not
+recommended for
+.Xr mdoc 7 ,
+which encourages semantic annotation.
+.Ss Predefined Strings
+Predefined strings, like
+.Sx Special Characters ,
+mark special output glyphs.
+Predefined strings are escaped with the slash-asterisk,
+.Sq \e* :
+single-character
+.Sq \e*X ,
+two-character
+.Sq \e*(XX ,
+and N-character
+.Sq \e*[N] .
+.Pp

+.It Li \e*(Am
+Two-letter ampersand predefined string.
+.It Li \e*q
+One-letter double-quote predefined string.
+.El
+.Pp
+Predefined strings are not recommended for use,
+as they differ across implementations.
+Those supported by
+.Xr mandoc 1
+are listed in
+.Xr mandoc_char 7 .
+Manuals using these predefined strings are almost certainly not portable.
+.Ss Whitespace
+Whitespace consists of the space character.
+In text lines, whitespace is preserved within a line.
+In request and macro lines, whitespace delimits arguments and is discarded.
+.Pp
+Unescaped trailing spaces are stripped from text line input unless in a
+literal context.
+In general, trailing whitespace on any input line is discouraged for
+reasons of portability.
+In the rare case that a blank character is needed at the end of an
+input line, it may be forced by
+.Sq \e\ \e& .
+.Pp
+Literal space characters can be produced in the output
+using escape sequences.
+In macro lines, they can also be included in arguments using quotation; see
+.Sx MACRO SYNTAX
+for details.
+.Pp
+Blank text lines, which may include whitespace, are only permitted
+within literal contexts.
+If the first character of a text line is a space, that line is printed
+with a leading newline.
+.Ss Scaling Widths
+Many requests and macros support scaled widths for their arguments.
+The syntax for a scaled width is
+.Sq Li [+-]?[0-9]*.[0-9]*[:unit:] ,
+where a decimal must be preceded or followed by at least one digit.
+Negative numbers, while accepted, are truncated to zero.
+.Pp
+The following scaling units are accepted:
+.Pp
+.Bl -tag -width Ds -offset indent -compact

+centimetre
+.It i

+.It n
+width of rendered
+.Sq n
+.Pq en

+.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.
+See
+.Sx COMPATIBILITY .
+.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.
+.Pp
+Examples:
+.Bl -tag -width ".Bl -tag -width 2i" -offset indent -compact

+.Ss Sentence Spacing
+Each sentence should terminate at the end of an input line.

+To be recognised as the beginning of a quoted argument, the opening
+quote character must be preceded by a space character.
+A quoted argument extends to the next double quote character that is not
+part of a pair, or to the end of the input line, whichever comes earlier.
+Leaving out the terminating double quote character at the end of the line
+is discouraged.
+For clarity, if more arguments follow on the same input line,

+by a space character; in case the next character after the terminating
+double quote character is anything else, it is regarded as the beginning

+.Sh DESCRIPTION
+The
+.Nm
+utility searches databases generated by
+.Xr mandocdb 8
+for manuals containing the word
+.Ar name
+in their page name, ignoring case.
+It returns the header lines from all matching pages.
+You can then use the
+.Xr man 1
+command to get more information.
+.Pp
+By default,
+.Nm
+searches for
+.Xr mandocdb 8
+databases in the default paths stipulated by
+.Xr man 1 .
+.Pp
+The options are as follows:
+.Bl -tag -width Ds
+.It Fl C Ar file
+Specify an alternative configuration
+.Ar file
+in
+.Xr man.conf 5
+format.
+.It Fl M Ar manpath
+Use the colon-separated
+.Ar manpath
+instead of the default list of paths searched for
+.Xr mandocdb 8
+databases.
+Invalid paths, or paths without manual databases, are ignored.
+.It Fl m Ar manpath
+Prepend the colon-separated
+.Ar manpath
+to the list of paths searched for
+.Xr mandocdb 8
+databases.
+Invalid paths, or paths without manual databases, are ignored.
+.It Fl S Ar arch
+Search only for a particular architecture.
+.It Fl s Ar cat
+Search only for a manual section.
+See
+.Xr man 1
+for a listing of manual sections.
+.El
+.Pp
+Results are sorted by manual title, with output formatted as
+.Pp
+.D1 title(sec) \- description
+.Pp
+Where
+.Qq title
+is the manual's title (note multiple manual names may exist for one
+title),
+.Qq sec
+is the manual section, and
+.Qq description
+is the manual's short description.
+If an architecture is specified for the manual, it is displayed as
+.Pp
+.D1 title(cat/arch) \- description
+.Pp
+Resulting manuals may be accessed as
+.Pp
+.Dl $ man \-s sec title
+.Pp
+If an architecture is specified in the output, use
+.Pp
+.Dl $ man \-s sec \-S arch title
+.Pp
+.Nm
+is identical to running
+.Xr apropos 1
+as follows:
+.Pp
+.Dl $ apropos -- -i 'Nm~[[:<:]]term[[:>:]]'
+.Sh ENVIRONMENT
+.Bl -tag -width Ds
+.It Ev MANPATH
+Colon-separated paths modifying the default list of paths searched for
+manual databases.
+Invalid paths, or paths without manual databases, are ignored.
+Overridden by
+.Fl M .
+If
+.Ev MANPATH
+begins with a
+.Sq \&: ,
+it is appended to the default list;
+else if it ends with
+.Sq \&: ,
+it is prepended to the default list; else if it contains
+.Sq \&:: ,
+the default list is inserted between the colons.
+If none of these conditions are met, it overrides the default list.
