-.SH NAME
-groff_markup \- groff macros for authoring web pages
-.LINE
-.SH SYNOPSIS
-.B "groff \-markup"
-[ options ]
-file ... 
-.SH DESCRIPTION
-This manual page describes the GNU \-markup macros, which is part of the
-groff document formatting system.
-The manual page is very a basic guide, and the html device driver
-.RB ( grohtml )
-is still very alpha.
-It has been included into the distribution so that a lot of people have a
-chance to test it.
-Note that this macro file will be automatically called (via the
-\fCtroffrc\fP file) if you use \fC-Thtml\fP.
-.PP
-To see the hyperlinks in action, please format this man page with the
-.B grohtml
-device.
-.PP
-Here is a summary of the functions found in this macro set.
-.SH SYNPOSIS
-.ta 2iL
-\&.HTMLINDEX	determine automatic link cut off

-.br
-.PP
-Output of the
-.IR pic ,
-.IR eqn ,
-.IR refer ,
-and
-.I tbl
-preprocessors is acceptable as input.
-.SH REQUESTS 
-.TP
-.B HTMLINDEX
-determines the cut off point for automatic link generation to headings.
-By default all headings found in a troff document have links created to them
-at the top of the html web page.
-It maybe that many of the lower heading levels do not require links.
-Alternatively some web pages may not need any heading links at all, in which
-case:
-.sp
-.nf
-\fC\&.HTMLINDEX 0\fP
-.fi
-.sp
-will tell
-.B grohtml
-not to generate links.
-An \fCHTMLINDEX\fP of 2 will mean that a heading
-.sp
-.B "1.1.1 Some Title"
-.sp
-will not be included in the links either as it is said to have a heading
-level of three.
-.TP
-.B BODYCOLOR
-takes five parameters: foreground, background, active hypertext link,
-hypertext link not yet visited, and visited hypertext link colour.
-.TP
-.B BACKGROUND
-the only parameter to this macro is the background image file.
-.TP
-.B URL
-generates
-.TAG URL
-a URL using either two or three arguments.
-$1 is the name of the link, $2 is the actual URL, and $3 is optional stuff
-to be printed immediately after $2.
-Here is how to encode
-.URL "homepage for groff" http://groff.ffii.org/ :
-.sp
-.nf
-\s-2\fC\&.URL "homepage for groff" http://groff.ffii.org/ :\fP\s+2
-.fi
-.sp
-If this is processed by a device other than \fC-Thtml\fP
-it appears as:
-homepage for groff \(lahttp://groff.ffii.org\(ra.
-The URL macro can be of any type; for example we can reference
-.URL "Eric Raymond's pic guide" pic.html
-by:
-.sp
-.nf
-\s-2\fC\&.URL "Eric Raymond's pic guide" pic.html\fP\s+2
-.fi
-.sp
-.TP
-.B MAILTO
-generates an email html reference.
-The first argument is mandatory as the email address.
-The optional second argument is the text you see in your browser, and
-an optional third argument is stuff printed immediately after the
-second argument.
-For example, the groff maintainers are
-.MAILTO wl@gnu.org "Werner Lemberg"
-and
-.MAILTO Ted.Harding@nessie.mcc.ac.uk "Ted Harding" .
-This is achieved by the following macros:
-.sp
-.nf
-\s-2\fC\&.MAILTO wl@gnu.org "Werner Lemberg"\fP
-.sp
-\fC\&.MAILTO Ted.Harding@nessie.mcc.ac.uk \\
-.br
-"Ted Harding" .\s+2\fP
-.fi
-.sp
-Note that all the urls actually are treated as consuming no textual space
-in groff.
-This could be considered as a bug since it causes some problems.
-To circumvent this, \fCtmac.arkup\fP inserts a zero-width character which
-expands to a harmless space (only if in HTML mode)
-.TP
-.B FTP
-indicates that data can be obtained via ftp.
-The first argument is the browser text and the second is the url.
-A third argument, similar to the macros above, is intended for stuff printed
-immediately after the second argument.
-The second and the third parameter are optional.
-As an example, here the location of the
-.FTP "current groff development distribution" \
-ftp://ftp.ffii.org/pub/groff/devel/groff-current.tar.gz .
-The macro example above was specified by:
-.sp
-\s-2\fC\&.FTP "current groff development distribution" \\
-.br
-ftp://ftp.ffii.org/pub/groff/devel/groff-current.tar.gz .\fP\s+2
-.sp
-.TP
-.B IMAGE
-allows the document to include pictures.
-The first argument is the image file.
-The next two arguments are optional:
-Argument two is the width in pixels (default is 400 pixels if absent).
-The third argument is the height in pixels (default is the width value if
-absent).
-.sp
-.TP
-.B HTML
-all text after this macro is treated as raw html.
-If the document is processed \fIwithout\fP \fC-Thtml\fP then
-the macro is ignored.
-This macro is a building block for other higher level macros.
-.sp
-For example, the \fCBACKGROUND\fP macro is defined as:
-.nf
-\fC\&.de BACKGROUND
-\&.   HTML <body background=\\$1>
-\&..
-\fP
-.fi
-.TP
-.B TAG
-generates an html name tag from its argument.
-This can then be referenced using the
-.URL URL #URL
-macro.
-As you can see, you must precede the tag name with `\fC#\fP' since it is
-a local reference.
-This link was achieved via placing a TAG in the URL description above;
-the source looks like this:
-.sp
-\s-2\fC\&.TP
-.br
-\&.B URL
-.br
-generates
-.br
-\&.TAG URL
-.br
-a URL using either two or three
-.br
-arguments.
-.br
-$1 is the name of the link, $2 is the actual URL
-.br
-\fP\s+2etc.
-.sp
-.\".TP
-.\".B CDFTP
-.\"takes four arguments.
-.\"Basically it is the FTP macro with optional local reference.
-.\"It was designed to allow the same groff source to be built on two different
-.\"machines and access the ftp data differently.
-.\"For example, on a web server you might wish for the web page to reference
-.\"a web site.
-.\"However, if you were producing a CDROM of your information you might wish
-.\"for the ftp data to be also stored on your CDROM and referenced as a file.
-.\"An example to get the current groff development distribution
-.\".CDFTP merlin "click here." \
-.\"ftp://ftp.ffii.org/pub/groff/devel/groff-current.tar.gz \
-.\"../../groff.tar.gz
-.\"The source for this CDFTP invocation is
-.\".sp
-.\"\fC\s-2\&.CDFTP merlin "click here." \
-.\"ftp://ftp.ffii.org/pub/groff/devel/groff-current.tar.gz \
-.\"../../groff.tar.gz\fP\s+2
-.\".sp
-.\"which means if the html is generated on machine \fCmerlin\fP
-.\"then generate a URL to \fC../../groff.tar.gz\fP.
-.\"Otherwise construct an FTP URL to 
-.\"\fCftp://ftp.ffii.org/pub/groff/devel/groff-current.tar.gz\fP.
-.TP
-.B LINE
-generates a full width horizontal rule.
-Example:
-.sp
-\fC\s-2\&.LINE\fP\s+2
-.sp
-.SH
-SECTION HEADING LINKS
-.LP
-By default
-.B grohtml
-generates links to all section headings and places these at the top of the
-html document.
-.B Grohtml
-has to guess what a section heading looks like \(em remember that all
-.B grohtml
-actually sees is a device independent language telling it where to place
-text, draw lines, change font sizes and faces etc.
-It believes a section heading to be a line of bold text which starts at the
-left most margin.
-Consequently it may misinterpret.
-Users can turn off all heading and title guessing by giving invoking groff
-with \fCgroff -P-g\fP.
-.SH
-LIMITATIONS OF GROHTML
-.LP
-Although basic text can be translated in a straightforward fashion there are
-some areas where
-.B grohtml
-has to try and guess text relationship.
-In particular, whenever
-.B grohtml
-encounters text tables and indented paragraphs or two column mode it will
-try and utilize the html table construct to preserve columns.
-.B Grohtml
-also attempts to work out which lines should be automatically formatted by
-the browser.
-Ultimately in trying to make reasonable guesses most of the time it will
-make mistakes.
-Hopefully these mistakes will happen less and less as we get bug reports
-and patches :-).
-.PP
-Tbl, pic, eqn's are also generated using images which may be
-considered a limitation.

-.Nm mdoc.samples
-.Nd tutorial sampler for writing
-.Bx
-manuals with
-.Nm \-mdoc
-.Sh SYNOPSIS
-.Nm man mdoc.samples
-.Sh DESCRIPTION
-A tutorial sampler for writing
-.Bx
-manual pages with the
-.Nm \-mdoc
-macro package, a
-.Em content Ns \-based
-and
-.Em domain Ns \-based
-formatting
-package for
-.Xr troff 1 .
-Its predecessor, the
-.Xr \-man 7
-package,
-addressed page layout leaving the
-manipulation of fonts and other
-typesetting details to the individual author.
-In
-.Nm \-mdoc ,
-page layout macros
-make up the
-.Em "page structure domain"
-which consists of macros for titles, section headers, displays
-and lists. Essentially items which affect the physical position
-of text on a formatted page.
-In addition to the page structure domain, there are two more domains,
-the manual domain and the general text domain.
-The general text domain is defined as macros which
-perform tasks such as quoting or emphasizing pieces of text.
-The manual domain is defined as macros that are a subset of the
-day to day informal language used to describe commands, routines
-and related
-.Bx
-files.
-Macros in the manual domain handle
-command names, command line arguments and options, function names,
-function parameters, pathnames, variables, cross
-references to other manual pages, and so on.
-These domain
-items have value
-for both the author and the future user of the manual page.
-It is hoped the consistency gained
-across the manual set will provide easier
-translation to future documentation tools.
-.Pp
-Throughout the
-.Ux
-manual pages, a manual entry
-is simply referred
-to as a man page, regardless of actual length and without
-sexist intention.
-.Sh GETTING STARTED
-Since a tutorial document is normally read when a person
-desires to use the material immediately, the assumption has
-been made that the user of this document may be impatient.

-.Sh TROFF IDIOSYNCRASIES
-The
-.Nm \-mdoc
-package attempts to simplify the process of writing a man page.
-Theoretically, one should not have to learn the dirty details of
-.Xr troff 1
-to use
-.Nm \-mdoc ;
-however, there are a few
-limitations which are unavoidable and best gotten out
-of the way.
-And, too, be forewarned, this package is
-.Em not
-fast.
-.Ss Macro Usage
-As in
-.Xr troff 1 ,
-a macro is called by placing a
-.Ql \&\.
-(dot character)
-at the beginning of
-a line followed by the two character name for the macro.
-Arguments may follow the macro separated by spaces.
-It is the dot character at the beginning of the line which causes
-.Xr troff 1
-to interpret the next two characters as a macro name.
-To place a
-.Ql \&\.
-(dot character)
-at the beginning of a line in some context other than
-a macro invocation, precede the
-.Ql \&\.
-(dot) with the
-.Ql \e&
-escape sequence.
-The
-.Ql \e&
-translates literally to a zero width space, and is never displayed in the
-output.
-.Pp
-In general,
-.Xr troff 1
-macros accept up to nine arguments, any
-extra arguments are ignored.
-Most macros in
-.Nm \-mdoc
-accept nine arguments and,
-in limited cases, arguments may be continued or extended
-on the
-next line (See
-.Sx Extended Arguments ) .
-A few macros handle quoted arguments (see
-.Sx Passing Space Characters in an Argument
-below).
-.Pp
-Most of the
-.Nm \-mdoc
-general text domain and manual domain macros are special
-in that their argument lists are
-.Em parsed
-for callable macro names.
-This means an argument on the argument list which matches
-a general text or manual domain macro name and is determined
-to be callable will be executed
-or called when it is processed.
-In this case
-the argument, although the name of a macro,
-is not preceded by a
-.Ql \&\.
-(dot).
-It is in this manner that many macros are nested; for
-example
-the option macro,
-.Ql \&.Op ,
-may
-.Em call
-the flag and argument macros,
-.Ql \&Fl
-and
-.Ql \&Ar ,
-to specify an optional flag with an argument:
-.Bl -tag -width "\&.Op \&Fl s \&Ar bytes" -offset indent
-.It Op Fl s Ar bytes
-is produced by
-.Li \&.Op \&Fl s \&Ar bytes
-.El
-.Pp
-To prevent a two character
-string from being interpreted as a macro name, precede
-the string with the
-escape sequence
-.Ql \e& :
-.Bl -tag -width "\&.Op \&Fl s \&Ar bytes" -offset indent
-.It Op \&Fl s \&Ar bytes
-is produced by
-.Li \&.Op \e&Fl s \e&Ar bytes
-.El
-.Pp
-Here the strings
-.Ql \&Fl
-and
-.Ql \&Ar
-are not interpreted as macros.
-Macros whose argument lists are parsed for callable arguments
-are referred to
-as parsed and macros which may be called from an argument
-list are referred to as callable
-throughout this document and in the companion quick reference
-manual
-.Xr mdoc 7 .
-This is a technical
-.Em faux pas
-as almost all of the macros in 
-.Nm \-mdoc
-are parsed, but as it was cumbersome to constantly refer to macros
-as being callable and being able to call other macros,
-the term parsed has been used.
-.Ss Passing Space Characters in an Argument
-Sometimes it is desirable to give as one argument a string
-containing one or more blank space characters.
-This may be necessary
-to defeat the nine argument limit or to specify arguments to macros
-which expect particular arrangement of items in the argument list.
-For example,
-the function macro
-.Ql \&.Fn
-expects the first argument to be the name of a function and any
-remaining arguments to be function parameters.
-As
-.Tn "ANSI C"
-stipulates the declaration of function parameters in the
-parenthesized parameter list, each parameter is guaranteed
-to be at minimum a two word string.
-For example,
-.Fa int foo .
-.Pp
-There are two possible ways to pass an argument which contains
-an embedded space.
-.Em Implementation note :
-Unfortunately, the most convenient way
-of passing spaces in between quotes by reassigning individual
-arguments before parsing was fairly expensive speed wise
-and space wise to implement in all the macros for
-.Tn AT&T
-.Xr troff .
-It is not expensive for
-.Xr groff
-but for the sake of portability, has been limited
-to the following macros which need
-it the most:
-.Pp
-.Bl -tag -width 4n -offset indent -compact
-.It Li \&Cd
-Configuration declaration (section 4
-.Sx SYNOPSIS )
-.It Li \&Bl
-Begin list (for the width specifier).
-.It Li \&Em
-Emphasized text.
-.It Li \&Fn
-Functions (sections two and four).
-.It Li \&It
-List items.
-.It Li \&Li
-Literal text.
-.It Li \&Sy
-Symbolic text.
-.It Li \&%B
-Book titles.
-.It Li \&%J
-Journal names.
-.It Li \&%O
-Optional notes for a reference.
-.It Li \&%R
-Report title (in a reference).
-.It Li \&%T
-Title of article in a book or journal.
-.El
-.Pp
-One way of passing a string
-containing blank spaces is to use the hard or unpaddable space character
-.Ql \e\  ,
-that is, a blank space preceded by the escape character
-.Ql \e .
-This method may be used with any macro but has the side effect
-of interfering with the adjustment of text
-over the length of a line.
-.Xr Troff
-sees the hard space as if it were any other printable character and
-cannot split the string into blank or newline separated pieces as one
-would expect.
-The method is useful for strings which are not expected
-to overlap a line boundary.
-For example:
-.Bl -tag -width "fetch(char *str)" -offset indent
-.It Fn fetch char\ *str
-is created by
-.Ql \&.Fn fetch char\e *str
-.It Fn fetch "char *str"
-can also be created by
-.Ql \&.Fn fetch "\\*q*char *str\\*q"
-.El
-.Pp
-If the
-.Ql \e
-or quotes
-were omitted,
-.Ql \&.Fn
-would see three arguments and
-the result would be:
-.Pp
-.Dl Fn fetch char *str
-.Pp
-For an example of what happens when the parameter list overlaps
-a newline boundary, see the
-.Sx BUGS
-section.
-.Ss Trailing Blank Space Characters
-.Xr Troff
-can be confused by blank space characters at the end of a line.
-It
-is a wise preventive measure to globally remove all blank spaces
-from <blank-space><end-of-line> character sequences.
-Should the need
-arise to force a blank character at the end of a line,
-it may be forced with an unpaddable space and the
-.Ql \e&
-escape character.
-For example,
-.Ql string\e\ \e& .
-.Ss Escaping Special Characters
-Special characters
-like the newline character
-.Ql \en ,
-are handled by replacing the
-.Ql \e
-with
-.Ql \ee
-(e.g.
-.Ql \een )
-to preserve
-the backslash.

-Several content macros are used to demonstrate page layout macros;
-reading about content macros before page layout macros is
-recommended.
-.Sh TITLE MACROS
-The title macros are the first portion of the page structure
-domain, but are presented first and separate for someone who
-wishes to start writing a man page yesterday.
-Three header macros designate the document title or manual page title,
-the operating system,
-and the date of authorship.
-These macros are one called once at the very beginning of the document
-and are used to construct the headers and footers only.
-.Bl -tag -width 6n
-.It Li \&.Dt DOCUMENT_TITLE section# [volume]
-The document title is the
-subject of the man page and must be in
-.Tn CAPITALS
-due to troff
-limitations.
-The section number may be 1,\ ...,\ 9,
-and if it is specified,
-the volume title may be omitted.
-A volume title may be arbitrary or one of the following:

-.El
-.Sh MANUAL DOMAIN
-.Ss What's in a name...
-The manual domain macro names are derived from the day to day
-informal language used to describe commands, subroutines and related
-files.
-Slightly
-different variations of this language are used to describe
-the three different aspects of writing a man page.
-First, there is the description of
-.Nm \-mdoc
-macro request usage.
-Second is the description of a
-.Ux
-command
-.Em with
-.Nm \-mdoc
-macros and third,
-the
-description of a command to a user in the verbal sense;
-that is, discussion of a command in the text of a man page.
-.Pp
-In the first case,
-.Xr troff 1
-macros are themselves a type of command;
-the general syntax for a troff command is:
-.Bd -filled -offset indent
-\&.Va argument1 argument2 ... argument9
-.Ed
-.Pp
-The
-.Ql \&.Va
-is a macro command or request, and anything following it is an argument to
-be processed.
-In the second case,
-the description of a
-.Ux
-command using the content macros is a
-bit more involved;
-a typical
-.Sx SYNOPSIS
-command line might be displayed as:
-.Bd -filled -offset indent
-.Nm filter
-.Op Fl flag
-.Ar infile outfile
-.Ed
-.Pp
-Here,
-.Nm filter
-is the command name and the
-bracketed string
-.Fl flag
-is a
-.Em flag
-argument designated as optional by the option brackets.
-In
-.Nm \-mdoc
-terms,
-.Ar infile
-and
-.Ar outfile
-are
-called
-.Em arguments .
-The macros which formatted the above example:
-.Bd -literal -offset indent
-\&.Nm filter
-\&.Op \&Fl flag
-\&.Ar infile outfile
-.Ed
-.Pp
-In the third case, discussion of commands and command syntax
-includes both examples above, but may add more detail.
-The
-arguments
-.Ar infile
-and
-.Ar outfile
-from the example above might be referred to as
-.Em operands
-or
-.Em file arguments .
-Some command line argument lists are quite long:
-.Bl -tag -width make -offset indent
-.It Nm make
-.Op Fl eiknqrstv
-.Op Fl D Ar variable
-.Op Fl d Ar flags
-.Op Fl f Ar makefile
-.Bk -words
-.Op Fl I Ar directory
-.Ek
-.Op Fl j Ar max_jobs
-.Op Ar variable=value
-.Bk -words
-.Op Ar target ...
-.Ek
-.El
-.Pp
-Here one might talk about the command
-.Nm make
-and qualify the argument
-.Ar makefile ,
-as an argument to the flag,
-.Fl f ,
-or discuss the optional
-file
-operand
-.Ar target .
-In the verbal context, such detail can prevent confusion,
-however the
-.Nm \-mdoc
-package
-does not have a macro for an argument
-.Em to
-a flag.
-Instead the
-.Ql \&Ar
-argument macro is used for an operand or file argument like
-.Ar target
-as well as an argument to a flag like
-.Ar variable .
-The make command line was produced from:
-.Bd -literal -offset indent
-\&.Nm make
-\&.Op Fl eiknqrstv
-\&.Op Fl D Ar variable
-\&.Op Fl d Ar flags
-\&.Op Fl f Ar makefile
-\&.Op Fl I Ar directory
-\&.Op Fl j Ar max_jobs
-\&.Op Ar variable=value
-\&.Bk -words
-\&.Op Ar target ...
-\&.Ek
-.Ed
-.Pp
-The
-.Ql \&.Bk
-and
-.Ql \&.Ek
-macros are explained in
-.Sx Keeps .
-.Ss General Syntax
-The manual domain and general text domain macros share a similar
-syntax with a few minor deviations:
-.Ql \&.Ar ,
-.Ql \&.Fl ,
-.Ql \&.Nm ,
-and
-.Ql \&.Pa
-differ only when called without arguments;
-.Ql \&.Fn
-and
-.Ql \&.Xr
-impose an order on their argument lists
-and the
-.Ql \&.Op
-and
-.Ql \&.Fn
-macros
-have nesting limitations.
-All content macros
-are capable of recognizing and properly handling punctuation,
-provided each punctuation character is separated by a leading space.
-If an request is given:
-.Pp
-.Dl \&.Li sptr, ptr),
-.Pp
-The result is:
-.Pp
-.Dl Li sptr, ptr),
-.Pp
-The punctuation is not recognized and all is output in the
-literal font. If the punctuation is separated by a leading
-white space:
-.Pp
-.Dl \&.Li "sptr , ptr ) ,"
-.Pp
-The result is:
-.Pp
-.Dl Li sptr , ptr ) ,
-.Pp
-The punctuation is now recognized and is output in the
-default font distinguishing it from the strings in literal font.
-.Pp
-To remove the special meaning from a punctuation character
-escape it with
-.Ql \e& .
-.Xr Troff
-is limited as a macro language, and has difficulty
-when presented with a string containing
-a member of the mathematical, logical or
-quotation set:
-.Bd -literal -offset indent-two
-\&{+,\-,/,*,\&%,<,>,<=,>=,=,==,&,`,',"}
-.Ed
-.Pp
-The problem is that
-.Xr troff
-may assume it is supposed to actually perform the operation
-or evaluation suggested by the characters.  To prevent
-the accidental evaluation of these characters,
-escape them with
-.Ql \e& .
-Typical syntax is shown in the first content macro displayed
-below,
-.Ql \&.Ad .
-.Ss Address Macro
-The address macro identifies an address construct
-of the form addr1[,addr2[,addr3]].
-.Pp
-.Dl Usage: .Ad address ... \*(Pu
-.Bl -tag -width ".Ad f1 , f2 , f3 :" -compact -offset 14n
-.It Li \&.Ad addr1

-.It Li \&.Ad addr\ )\ )\ ,
-.Ad addr ) ) ,
-.El
-.Pp
-It is an error to call
-.Li \&.Ad
-without arguments.
-.Li \&.Ad
-is callable by other macros and is parsed.
-.Ss Argument Macro
-The
-.Li \&.Ar
-argument macro may be used whenever
-a command line argument is referenced.
-.Pp
-.Dl Usage: .Ar argument ... \*(Pu
-.Bl -tag -width ".Ar file1 file2" -compact -offset 15n

-.El
-.Pp
-If
-.Li \&.Ar
-is called without arguments
-.Ql Ar
-is assumed.
-The
-.Li \&.Ar
-macro is parsed and is callable.
-.Ss Configuration Declaration (section four only)
-The
-.Ql \&.Cd
-macro is used to demonstrate a
-.Xr config 8
-declaration for a device interface in a section four manual.
-This macro accepts quoted arguments (double quotes only).
-.Pp
-.Bl -tag -width "device le0 at scode?" -offset indent
-.It Cd "device le0 at scode?"
-produced by:
-.Ql ".Cd device le0 at scode?" .
-.El
-.Ss Command Modifier
-The command modifier is identical to the
-.Ql \&.Fl
-(flag) command with the exception
-the
-.Ql \&.Cm
-macro does not assert a dash
-in front of every argument.
-Traditionally flags are marked by the
-preceding dash, some commands or subsets of commands do not use them.
-Command modifiers may also be specified in conjunction with interactive
-commands such as editor commands.
-See
-.Sx Flags .
-.Ss Defined Variables
-A variable which is defined in an include file is specified
-by the macro
-.Ql \&.Dv .
-.Pp
-.Dl Usage: .Dv defined_variable ... \*(Pu
-.Bl -tag -width ".Dv MAXHOSTNAMELEN" -compact -offset 14n
-.It Li ".Dv MAXHOSTNAMELEN"
-.Dv MAXHOSTNAMELEN

-.El
-.Pp
-It is an error to call
-.Ql \&.Dv
-without arguments.
-.Ql \&.Dv
-is parsed and is callable.
-.Ss Errno's (Section two only)
-The
-.Ql \&.Er
-errno macro specifies the error return value
-for section two library routines.
-The second example
-below shows
-.Ql \&.Er
-used with the
-.Ql \&.Bq
-general text domain macro, as it would be used in
-a section two manual page.
-.Pp
-.Dl Usage: .Er ERRNOTYPE ... \*(Pu

-.El
-.Pp
-It is an error to call
-.Ql \&.Ev
-without arguments.
-The
-.Ql \&.Ev
-macro is parsed and is callable.
-.Ss Function Argument
-The
-.Ql \&.Fa
-macro is used to refer to function arguments (parameters)
-outside of the
-.Sx SYNOPSIS
-section of the manual or inside
-the
-.Sx SYNOPSIS
-section should a parameter list be too
-long for the
-.Ql \&.Fn
-macro and the enclosure macros
-.Ql \&.Fo
-and
-.Ql \&.Fc
-must be used.
-.Ql \&.Fa
-may also be used to refer to structure members.
-.Pp
-.Dl Usage: .Fa function_argument ... \*(Pu
-.Bl -tag -width ".Fa d_namlen\ )\ )\ ," -compact -offset 14n
-.It Li \&.Fa d_namlen\ )\ )\ ,
-.Fa d_namlen ) ) ,
-.It Li \&.Fa iov_len
-.Fa iov_len
-.El
-.Pp
-It is an error to call
-.Ql \&.Fa
-without arguments.
-.Ql \&.Fa
-is parsed and is callable.
-.Ss Function Declaration
-The
-.Ql \&.Fd
-macro is used in the
-.Sx SYNOPSIS
-section with section two or three
-functions.
-The
-.Ql \&.Fd
-macro does not call other macros and is not callable by other
-macros.
-.Pp
-.Dl Usage: .Fd include_file (or defined variable)
-.Pp
-In the
-.Sx SYNOPSIS
-section a
-.Ql \&.Fd
-request causes a line break if a function has already been presented
-and a break has not occurred.
-This leaves a nice vertical space
-in between the previous function call and the declaration for the
-next function.
-.Ss Flags
-The
-.Ql \&.Fl
-macro handles command line flags.
-It prepends
-a dash,
-.Ql \- ,
-to the flag.
-For interactive command flags, which
-are not prepended with a dash, the
-.Ql \&.Cm
-(command modifier)
-macro is identical, but without the dash.
-.Pp
-.Dl Usage: .Fl argument ... \*(Pu
-.Bl -tag -width ".Fl \-s \-t \-v" -compact -offset 14n
-.It Li \&.Fl
-.Fl
-.It Li \&.Fl cfv
-.Fl cfv

-.It Li \&.Fl s v t
-.Fl s v t
-.It Li \&.Fl -\ ,
-.Fl - ,
-.It Li \&.Fl xyz\ )\ ,
-.Fl xyz ) ,
-.El
-.Pp
-The
-.Ql \&.Fl
-macro without any arguments results
-in a dash representing stdin/stdout.
-Note that giving
-.Ql \&.Fl
-a single dash, will result in two dashes.
-The
-.Ql \&.Fl
-macro is parsed and is callable.
-.Ss Functions (library routines)
-The .Fn macro is modeled on ANSI C conventions.
-.Bd -literal
-Usage: .Fn [type] function [[type] parameters ... \*(Pu]
-.Ed
-.Bl -tag -width ".Fn .int align. .const * char *sptrsxx" -compact
-.It Li "\&.Fn getchar"
-.Fn getchar
-.It Li "\&.Fn strlen ) ,"
-.Fn strlen ) ,
-.It Li \&.Fn "\\*qint align\\*q" "\\*qconst * char *sptrs\\*q" ,
-.Fn "int align" "const * char *sptrs" ,
-.El
-.Pp
-It is an error to call
-.Ql \&.Fn
-without any arguments.
-The
-.Ql \&.Fn
-macro
-is parsed and is callable,
-note that any call to another macro signals the end of
-the
-.Ql \&.Fn
-call (it will close-parenthesis at that point).
-.Pp
-For functions that have more than eight parameters (and this
-is rare), the
-macros
-.Ql \&.Fo
-(function open)
-and
-.Ql \&.Fc
-(function close)
-may be used with
-.Ql \&.Fa
-(function argument)
-to get around the limitation. For example:
-.Bd -literal -offset indent
-\&.Fo "int res_mkquery"
-\&.Fa "int op"
-\&.Fa "char *dname"
-\&.Fa "int class"
-\&.Fa "int type"
-\&.Fa "char *data"
-\&.Fa "int datalen"
-\&.Fa "struct rrec *newrr"
-\&.Fa "char *buf"
-\&.Fa "int buflen"
-\&.Fc
-.Ed
-.Pp
-Produces:
-.Bd -filled -offset indent
-.Fo "int res_mkquery"
-.Fa "int op"
-.Fa "char *dname"
-.Fa "int class"
-.Fa "int type"
-.Fa "char *data"
-.Fa "int datalen"
-.Fa "struct rrec *newrr"
-.Fa "char *buf"
-.Fa "int buflen"
-.Fc
-.Ed
-.Pp
-The
-.Ql \&.Fo
-and
-.Ql \&.Fc
-macros are parsed and are callable.
-In the
-.Sx SYNOPSIS
-section, the function will always begin at
-the beginning of line.
-If there is more than one function
-presented in the
-.Sx SYNOPSIS
-section and a function type has not been
-given, a line break will occur, leaving a nice vertical space
-between the current function name and the one prior.
-At the moment,
-.Ql \&.Fn
-does not check its word boundaries
-against troff line lengths and may split across a newline
-ungracefully.
-This will be fixed in the near future.
-.Ss Function Type
-This macro is intended for the
-.Sx SYNOPSIS
-section.
-It may be used
-anywhere else in the man page without problems, but its main purpose
-is to present the function type in kernel normal form for the
-.Sx SYNOPSIS
-of sections two and three
-(it causes a page break allowing the function name to appear
-on the next line).
-.Pp
-.Dl Usage: .Ft type ... \*(Pu

-.Ss Literals
-The
-.Ql \&.Li
-literal macro may be used for special characters,
-variable constants, anything which should be displayed as it
-would be typed.

-.Pp
-The
-.Ql \&.Li
-macro is parsed and is callable.
-.Ss Name Macro
-The
-.Ql \&.Nm
-macro is used for the document title or subject name.
-It has the peculiarity of remembering the first
-argument it was called with, which should
-always be the subject name of the page.
-When called without
-arguments,
-.Ql \&.Nm
-regurgitates this initial name for the sole purpose
-of making less work for the author.
-If trailing punctuation is required with this feature,
-use
-.Qq
-as a first argument to
-.Ql \&.Nm .
-Note:
-a section two
-or three document function name is addressed with the
-.Ql \&.Nm
-in the
-.Sx NAME
-section, and with
-.Ql \&.Fn
-in the
-.Sx SYNOPSIS
-and remaining sections.
-For interactive commands, such as the
-.Ql while
-command keyword in
-.Xr csh 1 ,
-the
-.Ql \&.Ic
-macro should be used.
-While the
-.Ql \&.Ic
-is nearly identical
-to
-.Ql \&.Nm ,
-it can not recall the first argument it was invoked with.

-.Ss Enclosure and Quoting Macros
-The concept of enclosure is similar to quoting.
-The object being to enclose one or more strings between
-a pair of characters like quotes or parentheses.
-The terms quoting and enclosure are used
-interchangeably throughout this document.
-Most of the
-one line enclosure macros end
-in small letter
-.Ql q
-to give a hint of quoting, but there are a few irregularities.
-For each enclosure macro
-there is also a pair of open and close macros which end
-in small letters
-.Ql o
-and
-.Ql c
-respectively.
-These can be used across one or more lines of text
-and while they have nesting limitations, the one line quote macros
-can be used inside
-of them.
-.Pp
-.ne 5
-.Bd -filled -offset indent
-.Bl -column "quote " "close " "open " "Enclose Stringx(in XX) " XXstringXX
-.Em " Quote	 Close	 Open	Function	Result"

-\&.Qq	.Qc	.Qo	Straight Double Quote	"string"
-\&.Sq	.Sc	.So	Single Quote	`string'
-.El
-.Ed
-.Pp
-Except for the irregular macros noted below, all
-of the quoting macros are parsed and callable.
-All handle punctuation properly, as long as it
-is presented one character at a time and separated by spaces.
-The quoting macros examine opening and closing punctuation
-to determine whether it comes before or after the
-enclosing string. This makes some nesting possible.
-.Bl -tag -width xxx,xxxx
-.It Li \&.Ec , \&.Eo
-These macros expect the first argument to be the
-opening and closing strings respectively.
-.It Li \&.Ql
-The quoted literal macro behaves differently for
-.Xr troff
-than
-.Xr nroff .
-If formatted with
-.Xr nroff ,
-a quoted literal is always quoted. If formatted with
-troff, an item is only quoted if the width
-of the item is less than three constant width characters.
-This is to make short strings more visible where the font change
-to literal (constant width) is less noticeable.
-.It Li \&.Pf
-The prefix macro is not callable, but it is parsed:
-.Bl -tag -width "(namexx" -offset indent
-.It Li ".Pf ( Fa name2"
-becomes
-.Pf ( Fa name2 .
-.El
-.It Li \&.Ns
-The
-.Ql \&.Ns
-(no space) macro, which
-.Em is

-For a good example of nested enclosure macros, see the

-option macro.
-It was created from the same
-underlying enclosure macros as those presented in the list
-above.
-The
-.Ql \&.Xo
-and
-.Ql \&.Xc
-extended argument list macros
-were also built from the same underlying routines and are a good
-example of
-.Nm \-mdoc
-macro usage at its worst.
-.Ss No\-Op or Normal Text Macro
-The macro
-.Li \&.No
-is
-a hack for words in a macro command line which should
-.Em not
-be formatted and follows the conventional syntax
-for content macros.
-.Ss No Space Macro
-The
-.Ql \&.Ns
-macro eliminates unwanted spaces in between macro requests.
-It is useful for old style argument lists where there is no space
-between the flag and argument:
-.Bl -tag -width ".Op Fl I Ns Ar directoryxx" -offset indent
-.It Li ".Op Fl I Ns Ar directory"
-produces
-.Op Fl I Ns Ar directory
-.El
-.Pp
-Note: the
-.Ql \&.Ns
-macro always invokes the
-.Ql \&.No
-macro after eliminating the space unless another macro name
-follows it.
-The macro
-.Ql \&.Ns
-is parsed and is callable.
-.Ss Section Cross References
-The
-.Ql \&.Sx
-macro designates a reference to a section header
-within the same document.
-It is parsed and is callable.

-refer style references.
-.Pp
-.Bl -tag -width 6n -offset indent -compact
-.It Li ".Rs"
-Reference Start.

-The macros beginning with

-are not callable, and are parsed only for the trade name macro which
-returns to its caller.
-(And not very predictably at the moment either.)
-The purpose is to allow trade names
-to be pretty printed in
-.Xr troff Ns / Ns Xr ditroff
-output.
-.Ss Trade Names (or Acronyms and Type Names)
-The trade name macro is generally a small caps macro for
-all upper case words longer than two characters.

-.Ss Extended Arguments
-The
-.Li \&.Xo
-and
-.Li \&.Xc
-macros allow one to extend an argument list
-on a macro boundary.
-Argument lists cannot
-be extended within a macro
-which expects all of its arguments on one line such
-as
-.Ql \&.Op .
-.Pp
-Here is an example of
-.Ql \&.Xo
-using the space mode macro to turn spacing off:
-.Bd -literal -offset indent
-\&.Sm off
-\&.It Xo Sy I Ar operation
-\&.No \een Ar count No \een
-\&.Xc
-\&.Sm on
-.Ed

-Another example of
-.Ql \&.Xo
-and using enclosure macros:
-Test the value of an variable.
-.Bd -literal -offset indent
-\&.It Xo

-.Bl -tag -width flag -compact
-.It Xo
-.Ic .ifndef
-.Oo \&! Oc Ns Ar variable
-.Op Ar operator variable ...
-.Xc
-.El
-.Ed
-.Pp
-All of the above examples have used the
-.Ql \&.Xo
-macro on the argument list of the
-.Ql \&.It
-(list-item)
-macro.
-The extend macros are not used very often, and when they are
-it is usually to extend the list-item argument list.
-Unfortunately, this is also where the extend macros are the
-most finicky.
-In the first two examples, spacing was turned off;
-in the third, spacing was desired in part of the output but
-not all of it.
-To make these macros work in this situation make sure
-the
-.Ql \&.Xo
-and
-.Ql \&.Xc
-macros are placed as shown in the third example.
-If the
-.Ql \&.Xo
-macro is not alone on the
-.Ql \&.It
-argument list, spacing will be unpredictable.
-The
-.Ql \&.Ns
-(no space macro)
-must not occur as the first or last macro on a line
-in this situation.
-Out of 900 manual pages (about 1500 actual pages)
-currently released with
-.Bx
-only fifteen use the
-.Ql \&.Xo
-macro.
-.Sh PAGE STRUCTURE DOMAIN
-.Ss Section Headers
-The first three
-.Ql \&.Sh
-section header macros
-list below are required in every
-man page.
-The remaining section headers
-are recommended at the discretion of the author
-writing the manual page.
-The
-.Ql \&.Sh
-macro can take up to nine arguments.
-It is parsed and but is not callable.
-.Bl -tag -width ".Sh SYNOPSIS"
-.It \&.Sh NAME
-The
-.Ql \&.Sh NAME
-macro is mandatory.
-If not specified,
-the headers, footers and page layout defaults
-will not be set and things will be rather unpleasant.
-The
-.Sx NAME
-section consists of at least three items.
-The first is the
-.Ql \&.Nm
-name macro naming the subject of the man page.
-The second is the Name Description macro,
-.Ql \&.Nd ,
-which separates the subject
-name from the third item, which is the description.
-The
-description should be the most terse and lucid possible,
-as the space available is small.
-.It \&.Sh SYNOPSIS
-The
-.Sx SYNOPSIS
-section describes the typical usage of the
-subject of a man page.
-The  macros required
-are either
-.Ql ".Nm" ,
-.Ql ".Cd" ,
-.Ql ".Fn" ,
-(and possibly
-.Ql ".Fo" ,
-.Ql ".Fc" ,
-.Ql ".Fd" ,
-.Ql ".Ft"
-macros).
-The function name
-macro
-.Ql ".Fn"
-is required
-for manual page sections 2 and 3, the command and general
-name macro
-.Ql \&.Nm
-is required for sections 1, 5, 6, 7, 8.
-Section 4 manuals require a
-.Ql ".Nm" , ".Fd"
-or a
-.Ql ".Cd"
-configuration device usage macro.
-Several other macros may be necessary to produce
-the synopsis line as shown below:
-.Pp
-.Bd -filled -offset indent
-.Nm cat
-.Op Fl benstuv
-.Op Fl
-.Ar
-.Ed
-.Pp
-The following macros were used:
-.Pp
-.Dl \&.Nm cat
-.Dl \&.Op \&Fl benstuv
-.Dl \&.Op \&Fl
-.Dl \&.Ar
-.Pp
-.Sy Note :
-The macros
-.Ql \&.Op ,
-.Ql \&.Fl ,
-and
-.Ql \&.Ar
-recognize the pipe bar character
-.Ql \*(Ba ,
-so a command line such as:
-.Pp
-.Dl ".Op Fl a | Fl b"
-.Pp
-will not go orbital.
-.Xr Troff
-normally interprets a \*(Ba as a special operator.
-See
-.Sx PREDEFINED STRINGS
-for a usable \*(Ba
-character in other situations.
-.It \&.Sh DESCRIPTION
-In most cases the first text in the
-.Sx DESCRIPTION
-section
-is a brief paragraph on the command, function or file,
-followed by a lexical list of options and respective
-explanations.
-To create such a list, the
-.Ql \&.Bl
-begin-list,
-.Ql \&.It
-list-item and
-.Ql \&.El
-end-list
-macros are used (see
-.Sx Lists and Columns
-below).
-.El
-.Pp
-The following
-.Ql \&.Sh
-section headers are part of the
-preferred manual page layout and must be used appropriately
-to maintain consistency.
-They are listed in the order
-in which they would be used.
-.Bl -tag -width SYNOPSIS
-.It \&.Sh ENVIRONMENT
-The
-.Sx ENVIRONMENT
-section should reveal any related
-environment
-variables and clues to their behavior and/or usage.
-.It \&.Sh EXAMPLES
-There are several ways to create examples.
-See
-the
-.Sx EXAMPLES
-section below
-for details.
-.It \&.Sh FILES
-Files which are used or created by the man page subject
-should be listed via the
-.Ql \&.Pa
-macro in the
-.Sx FILES
-section.
-.It \&.Sh SEE ALSO
-References to other material on the man page topic and
-cross references to other relevant man pages should
-be placed in the
-.Sx SEE ALSO
-section.
-Cross references
-are specified using the
-.Ql \&.Xr
-macro.
-At this time
-.Xr refer 1
-style references are not accommodated.
-.Pp
-It is recommended that the cross references are sorted on the section
-number, and then alphabetically on the names within a section.
-.It \&.Sh STANDARDS
-If the command, library function or file adheres to a
-specific implementation such as
-.St -p1003.2
-or
-.St -ansiC
-this should be noted here.
-If the
-command does not adhere to any standard, its history
-should be noted in the
-.Sx HISTORY
-section.
-.It \&.Sh HISTORY
-Any command which does not adhere to any specific standards
-should be outlined historically in this section.
-.It \&.Sh AUTHORS
-Credits, if need be, should be placed here.
-.It \&.Sh DIAGNOSTICS
-Diagnostics from a command should be placed in this section.
-.It \&.Sh ERRORS
-Specific error handling, especially from library functions
-(man page sections 2 and 3) should go here.
-The
-.Ql \&.Er
-macro is used to specify an errno.
-.It \&.Sh BUGS
-Blatant problems with the topic go here...
-.El
-.Pp
-User specified
-.Ql \&.Sh

-.Ed
-.Ss Paragraphs and Line Spacing.
-.Bl -tag -width 6n
-.It \&.Pp
-The \&.Pp paragraph command may
-be used to specify a line space where necessary.
-The macro is not necessary after a
-.Ql \&.Sh

-.Ql \&.Ss
-macro or before
-a
-.Ql \&.Bl

-.Ss Keeps
-The only keep that is implemented at this time is for words.
-The macros are
-.Ql \&.Bk
-(begin-keep)
-and
-.Ql \&.Ek
-(end-keep).
-The only option that
-.Ql \&.Bl
-accepts is
-.Fl words
-and is useful for preventing line breaks in the middle of options.
-In the example for the make command line arguments (see
-.Sx What's in a name ) ,
-the keep prevented
-.Xr nroff
-from placing up the
-flag and the argument
-on separate lines.
-(Actually, the option macro used to prevent this from occurring,
-but was dropped when the decision (religious) was made to force
-right justified margins in
-.Xr troff
-as options in general look atrocious when spread across a sparse
-line.
-More work needs to be done with the keep macros, a
-.Fl line
-option needs to be added.)
-.Ss Examples and Displays
-There are six types of displays, a quickie one line indented display
-.Ql \&.D1 ,
-a quickie one line literal display
-.Ql \&.Dl ,
-and block literal, block filled, block unfilled, and block ragged which use
-the
-.Ql \&.Bd
-begin-display
-and
-.Ql \&.Ed
-end-display macros.
-.Pp
-.Bl -tag -width \&.Dlxx
-.It Li \&.D1
-(D-one) Display one line of indented text.
-This macro is parsed, but it is not callable.
-.Pp
-.Dl Fl ldghfstru
-.Pp
-The above was produced by:
-.Li \&.Dl Fl ldghfstru .
-.It Li \&.Dl
-(D-ell)
-Display one line of indented
-.Em literal
-text.
-The
-.Ql \&.Dl
-example macro has been used throughout this
-file.
-It allows
-the indent (display) of one line of text.
-Its default font is set to
-constant width (literal) however
-it is parsed and will recognized other macros.
-It is not callable however.
-.Pp
-.Dl % ls -ldg /usr/local/bin
-.Pp
-The above was produced by
-.Li \&.Dl % ls -ldg /usr/local/bin .
-.It Li \&.Bd
-Begin-display.
-The
-.Ql \&.Bd
-display must be ended with the
-.Ql \&.Ed
-macro.
-Displays may be nested within lists, but may
-.Em not
-contain other displays; this also prohibits nesting
-of .D1 and .Dl one-line displays.
-.Ql \&.Bd
-has the following syntax:
-.Pp
-.Dl ".Bd display-type [-offset offset_value] [-compact]"
-.Pp
-The display-type must be one of the following four types and
-may have an offset specifier for indentation:
-.Ql \&.Bd .
-.Pp
-.Bl -tag -width "file file_name  " -compact
-.It Fl ragged
-Fill, but do not adjust the right margin.
-.It Fl unfilled
-Do not fill: display a block of text as typed, the
-right (and left) margin edges are left ragged.
-.It Fl filled
-Display a filled (formatted) block.
-The block of text is formatted (the edges are filled \-
-not left unjustified).
-.It Fl literal
-Display a literal block, useful for source code or
-simple tabbed or spaced text.
-.It Fl file Ar file_name
-The file name following the
-.Fl file
-flag is read and displayed.
-Literal mode is
-asserted and tabs are set at 8 constant width character
-intervals, however any
-.Xr troff/ Ns Nm \-mdoc
-commands in file will be processed.
-.It Fl offset Ar string
-If
-.Fl offset
-is specified with one of the following strings, the string
-is interpreted to indicate the level of indentation for the
-forthcoming block of text:
-.Pp
-.Bl -tag -width "indent-two" -compact
-.It Ar left
-Align block on the current left margin,
-this is the default mode of
-.Ql \&.Bd .
-.It Ar center
-Supposedly center the block.
-At this time
-unfortunately, the block merely gets
-left aligned about an imaginary center margin.
-.It Ar indent
-Indents by one default indent value or tab.
-The default
-indent value is also used for the
-.Ql \&.D1
-display so one is guaranteed the two types of displays
-will line up.
-This indent is normally set to 6n or about two
-thirds of an inch (six constant width characters).
-.It Ar indent-two
-Indents two times the default indent value.
-.It Ar right
-This
-.Em left
-aligns the block about two inches from
-the right side of the page.
-This macro needs
-work and perhaps may never do the right thing by
-.Xr troff .
-.El
-.El
-.It ".Ed"
-End-display.
-.El
-.Ss Tagged Lists and Columns
-There are several types of lists which may be initiated with the
-.Ql ".Bl"
-begin-list macro.
-Items within the list
-are specified with the
-.Ql ".It"
-item macro and
-each list must end with the
-.Ql ".El"
-macro.
-Lists other than
-.Li \-enum
-may be nested within themselves and within displays.
-The use of columns inside of lists or lists inside of columns
-is unproven.
-.Pp
-In addition, several list attributes may be specified such as
-the width of a tag, the list offset, and compactness
-(blank lines between items allowed or disallowed).
-Most of this document has been formatted with a tag style list
-.Pq Fl tag .
-For a change of pace, the list-type used to present the list-types
-is an over-hanging list
-.Pq Fl ohang .
-This type of list is quite popular with
-.Tn TeX
-users, but might look a bit funny after having read many pages of
-tagged lists.
-The following list types are accepted by
-.Ql ".Bl" :
-.Pp
-.Bl -ohang -compact
-.It Fl bullet
-.It Fl dash
-.It Fl enum
-.It Fl hyphen
-.It Fl item
-These five are the simplest types of lists.

-.Sh DIAGNOSTICS
-The debugging facilities for
-.Nm \-mdoc
-are limited, but can help detect subtle errors such
-as the collision of an argument name with an internal
-register or macro name.
-(A what?)
-A register is an arithmetic storage class for
-.Xr troff
-with a one or two character name.
-All registers internal to
-.Nm \-mdoc
-for
-.Xr troff
-and
-.Xr ditroff
-are two characters and
-of the form <upper_case><lower_case> such as
-.Ql \&Ar ,
-<lower_case><upper_case> as
-.Ql \&aR
-or
-<upper or lower letter><digit> as
-.Ql \&C\&1 .
-And adding to the muddle,
-.Xr troff
-has its own internal registers all of which are either
-two lower case characters or a dot plus a letter or meta-character
-character.
-In one of the introduction examples, it was shown how to
-prevent the interpretation of a macro name with the escape sequence
-.Ql \e& .
-This is sufficient for the internal register names also.
-.Pp
-.\" Every callable macro name has a corresponding register
-.\" of the same name (<upper_case><lower_case>).
-.\" There are also specific registers which have
-.\" been used for stacks and arrays and are listed in the
-.\" .Sx Appendix .
-.\" .Bd -ragged -offset 4n
-.\" [A-Z][a-z]	registers corresponding to macro names (example ``Ar'')
-.\" [a-z][A-Z]	registers corresponding to macro names (example ``aR'')
-.\" C[0-9]		argument types (example C1)
-.\" O[0-9]		offset stack (displays)
-.\" h[0-9]		horizontal spacing stack (lists)
-.\" o[0-9]		offset (stack) (lists)
-.\" t[0-9]		tag stack (lists)
-.\" v[0-9]		vertical spacing stack (lists)
-.\" w[0-9]		width tag/label stack
-.\" .Ed
-.\" .Pp
-If a non-escaped register name is given in the argument list of a request
-unpredictable behavior will occur.
-In general, any time huge portions
-of text do not appear where expected in the output, or small strings
-such as list tags disappear, chances are there is a misunderstanding
-about an argument type in the argument list.
-Your mother never intended for you to remember this evil stuff - so here
-is a way to find out whether or not your arguments are valid: The
-.Ql \&.Db
-(debug)
-macro displays the interpretation of the argument list for most
-macros.
-Macros such as the
-.Ql \&.Pp
-(paragraph)
-macro do not contain debugging information.
-All of the callable macros do,
-and it is strongly advised whenever in doubt,
-turn on the
-.Ql \&.Db
-macro.
-.Pp
-.Dl Usage: \&.Db [on | off]
-.Pp
-An example of a portion of text with
-the debug macro placed above and below an
-artificially created problem (a flag argument
-.Ql \&aC
-which should be
-.Ql \e&aC
-in order to work):
-.Bd -literal -offset indent
-\&.Db on
-\&.Op Fl aC Ar file )
-\&.Db off
-.Ed
-.Pp
-The resulting output:
-.Bd -literal -offset indent
-DEBUGGING ON
-DEBUG(argv) MACRO: `.Op'  Line #: 2

-	Argc: 5  Argv: `)'  Length: 1
-	Space: ` '  Class: Closing Punctuation or suffix
-	MACRO REQUEST: .Op Fl aC Ar file )
-DEBUGGING OFF
-.Ed
-.Pp
-The first line of information tells the name of the calling
-macro, here
-.Ql \&.Op ,
-and the line number it appears on.
-If one or more files are involved
-(especially if text from another file is included) the line number
-may be bogus.
-If there is only one file, it should be accurate.
-The second line gives the argument count, the argument
-.Pq Ql \&Fl
-and its length.
-If the length of an argument is two characters, the
-argument is tested to see if it is executable (unfortunately, any
-register which contains a non-zero value appears executable).
-The third line gives the space allotted for a class, and the
-class type.
-The problem here is the argument aC should not be
-executable.
-The four types of classes are string, executable, closing
-punctuation and opening punctuation.
-The last line shows the entire
-argument list as it was read.
-In this next example, the offending
-.Ql \&aC
-is escaped:
-.Bd -literal -offset indent
-\&.Db on
-\&.Em An escaped \e&aC
-\&.Db off
-.Ed
-.Bd -literal -offset indent
-DEBUGGING ON

-DEBUGGING OFF
-.Ed
-.Pp
-The argument
-.Ql \e&aC
-shows up with the same length of 2 as the
-.Ql \e&
-sequence produces a zero width, but a register
-named
-.Ql \e&aC
-was not found and the type classified as string.
-.Pp
-Other diagnostics consist of usage statements and are self explanatory.
-.Sh GROFF, TROFF AND NROFF
-The
-.Nm \-mdoc
-package does not need compatibility mode with
-.Xr groff .
-.Pp
-The package inhibits page breaks, and the headers and footers
-which normally occur at those breaks with
-.Xr nroff ,
-to make the manual more efficient for viewing on-line.
-At the moment,
-.Xr groff
-with
-.Fl T Ns Ar ascii
-does eject the imaginary remainder of the page at end of file.
-The inhibiting of the page breaks makes
-.Xr nroff Ns 'd
-files unsuitable for hardcopy.
-There is a register named
-.Ql \&cR
-which can be set to zero in the site dependent style file
-.Pa /usr/src/share/tmac/doc-nroff
-to restore the old style behavior.

-msafer \- groff -msafer macros
-.SH SYNOPSIS
-.B groff
-.B \-msafer
-[
-.IR options .\|.\|.

-[

-]
-.SH DESCRIPTION
-The -msafer macros remove the
-.BR open ,
-.BR opena ,
-.BR pso ,
-.B sy
-and
-.B pi
-requests.
-These macros should be used when processing input from
-an untrustworthy source.
-For maximum safety,
-they should be the first -m option on the command-line.
-Normally they are invoked using the
-.B \-S
-option of groff, which will also pass
-.B @g@pic
-the
-.B \-S
-flag.
