gbranden pushed a commit to branch master
in repository groff.
commit 1d2df80a933dd9c32dd0076280629b034f67892b
Author: G. Branden Robinson <address@hidden>
AuthorDate: Wed Apr 22 18:16:13 2020 +1000
Delete groffer.
Per discussion on the groff development mailing list, there is
no desire to retain the maintenance of this portion of the groff
distribution.
See <https://lists.gnu.org/archive/html/groff/2020-04/msg00051.html>
et seq.
* contrib/groffer: Recursively delete.
* Makefile.am:
* arch/mingw/mingw.am: Stop building groffer.
* m4/groff.m4 (GROFF_GROFFERDIR_OPTION):
(GROFF_GROFFERDIR_OPTION): Delete; remove "--with-grofferdir"
configuration option.
* MANIFEST:

Historical references to groffer deliberately remain in ChangeLog,
ChangeLog.{118,120}, NEWS, contrib/{chem,glilypond}/ChangeLog,
and doc/webpage.ms. This is a case of deletion, not damnatio memoriae.
Some minor cosmetic changes came along for the ride:
* contrib/groff_filenames/groff_filenames.5.man: Use literal section
numbers for non-groff man page cross-references; the expansions
@MAN[157]EXT@ are determined by groff configuration parameters and not
appropriate for other pages.
* contrib/groff_filenames/groff_filenames.5.man: Refer to Heirloom
Doctools project as such, not "Heirloom roff", and stop ascribing its
ownership to Gunnar Ritter; as I understand it, he stopped working on
it years ago, and it is now maintained by others.
* PROJECTS:
* TODO: Correct asymmetric `quotes' in copyright comments.
* contrib/chem/chem.1.man:
* contrib/gperl/gperl.1.man:
* contrib/gpinyin/gpinyin.1.man Stop preventing hyphenation on words
that won't get hyphenated; no visible effect on output.
* contrib/gperl/gperl.1.man:
* contrib/groff_filenames/groff_filenames.5.man:
* src/roff/grog/grog.1.man: Fix source style nit in sectioning; no
visible effect on output.

-
- The groffer versions 1.* have two kinds of program, a shell
- version and a Perl version.
-
- The shell version is kept from the old shell only versions of
- groffer 0.*. Most of the former files in the main groffer
- directory are now moved to the subdirectoy shell/.
-
- The Perl version of groffer is a complete rewrite; most of its
- files are found in the subdirectory perl/.
-
- The Makefile.sub decides whether the shell or Perl version of
- groffer is installed. This is done by the program perl_test.pl.
-
- In the following, all files in the groffer directory tree are
- mentioned.
-
- * ChangeLog: This file. It contains information for `groffer'
- versions >= 1.0.0 with shell and Perl kinds. For older `groffer'
- versions, see `shell/ChangeLog.0' which contains information for
- the shell only versions of groffer 0.*.
-
- * Makefile.sub: The old `Makefile.sub' was extended to support the
- shell and the Perl version of `groffer' at the same time. If the
- test of `perl_test.pl' succeeds the `groffer' Perl version will be
- installed, otherwise the shell version is used.
-
- * perl_test.pl: This is used by `Makefile.sub' and installed with
- the Perl version of `groffer'. It is a test of the installed perl
- version. The installed Perl version should be greater or equal
- than the version that is required by this file.
-
- * version.sh: This is the old file kept from the shell version of
- `groffer'. It stores the `groffer' version, the date of the last
- update, and the `groff' version. It is used and installed for the
- shell and Perl version of `groffer'.
-
- * README: This is the old `README' file extended by information on
- the shell and Perl kinds of `groffer'.
-
- * perl/: Subdirectory for the Perl version of `groffer'.
-
- * perl/groffer.pl: This is the `groffer' script of the Perl
- version, a Perl source file that handles the complete groffer
- functionality.
-
- * perl/man.pl: This is the collection of functions that are
- related to man pages, `apropos', and `whatis'. It is loaded by
- `perl/groffer.pl'.
-
- * perl/func.pl: This is the collection of miscellaneous functions.
- It is loaded by `perl/groffer.pl'.
-
- * perl/split_env.sh: A shell script that is used by
- `perl/groffer.pl' to split a large shell environment variable to a
- Perl array.
-
- * perl/groffer.man: This is the man page of the Perl version of
- `groffer'. It is derived from `groffer.man' of the shell version.
- It will only be installed when the `Makefile.sub' chooses to
- install the Perl version of 'groffer' instead of the shell
- version.
-
- * perl/README_PERL: This file contains information of the Perl
- compatibility and details that are special to the Perl version.
-
- * shell/: Subdirectory for the shell version of `groffer'.
-
- * shell/ChangeLog.0: The former `ChangeLog' file of the groffer
- versions 0.* was moved to this file. It contains information of
- the shell only version of groffer 0.*.
-
- * shell/groffer.sh: This is the old `groffer.sh' file of the shell
- version.
-
- * shell/groffer2.sh: This is the old `groffer2.sh' file of the
- shell version.
-
- * shell/groffer.man: This is the old man page groffer.man of the
- shell version. The shell version keeps its own man page. It will
- only be installed when the `Makefile.sub' chooses to install the
- shell version instead of the Perl version.
-
- * shell/README_SH: This is the old `README_SH' file of the shell
- version containing information of the shell compatibility.
-
- The former part of the ChangeLog file is in `shell/ChangeLog.0'.

-README
-
-The 'groffer' program is the easiest way to read documents written in
-some 'roff' language, such as the 'man pages', the manual pages in
-many operating systems. All 'roff' preprocessors, such as 'chem' or
-'glilypond', are detected and executed automatically.
-
-
-Input
-
-Input comes from either standard input or command-line parameters that
-represent names of exisiting roff files or standardized specifications
-for searching man pages. All of these can be compressed in a format
-that is decompressible by 'gzip' or 'bzip2', including '.gz', 'bz2',
-and '.Z'.
-
-'groffer' has many built-in 'man' functionalities to find and read the
-manual pages on Unix and similar operating systems. It accepts the
-information from an installed 'man' program, but tries to find a man
-path by itself.
-
-'groffer' bundles all filespec parameters into a single output file in
-the same way as 'groff'. The disadvantage of this is that all file
-name arguments must use the same groff language. To change this, the
-option parsing must be revised for large parts. It seems that this
-would create incompatibilities, so the actual option strategy is kept.
-
-
-Output
-
-All input is first sent to 'grog' to determine the necessary 'groff'
-command and then to 'groff' together with all necessary preprocessors.
-So no special 'groff' arguments must be given. But all 'groff'
-options can be specified when this seems to be appropriate.
-
-The following displaying modes for the output are available:
-- Display formatted input with
--- a PDF viewer,
--- a Postcript viewer,
--- a web browser,
--- the X 'roff' viewer 'gxditview',
--- a DVI viewer,
--- a pager in a text terminal (tty).
-- Generate 'groff' output on stdout without a viewer.
-- Generate the 'groff intermediate output' on standard output without
- postprocessing.
-- Output the source code without any 'groff' processing.
-- There are some information outputs without 'groff' processing, such
- as by option '-V' and the 'man' like 'whatis' and 'apropos'
- outputs.
-
-By default, the program creates a PDF file; on non-X text terminals,
-the 'tty' text mode with a pager is tried by default.
-
-
-File access
-
-The Perl version of groffer now uses a umask of 077. This is a very
-strict security issue. It allows only access of the temporary files
-by the file owner.
-
-
-Compatibility
-
-'groffer' is compatible to the 'man' program. It supports '.so'
-requests based on the man path and compressed files. That's more than
-'groff' does.
-
-
-Reporting bugs
-
-For reporting bugs of 'groffer', groff's bug-tracking tool at
-http://savannah.gnu.org/bugs/?group=groff can be used.
-
-
-Mailing list
-
-For a general discussion, the mailing list <address@hidden> is

-.
-The
-.B \%groffer
-program is the easiest way to use
-.BR \%groff (@MAN1EXT@).
-It can display arbitrary documents written in the
-.I \%groff
-language, see
-.BR \%groff (@MAN7EXT@),
-or other
-.I \%roff
-languages, see
-.BR \%roff (@MAN7EXT@),
-that are compatible to the original
-.I \%troff
-language.
-.
-It finds and runs all necessary
-.I groff
-preprocessors, such as
-.BR @g@chem .
-.
-.
-.P
-The
-.B \%groffer
-program also includes many of the features for finding and displaying
-the \%\f(CRUnix\fP manual pages
-.nh
-.RI ( man\~pages ),
-.hy
-such that it can be used as a replacement for a
-.BR \%man (1)
-program.
-.
-Moreover, compressed files that can be handled by
-.BR \%gzip (1)
-or
-.BR \%bzip2 (1)
-are decompressed on-the-fly.
-.
-.
-.P
-The normal usage is quite simple by supplying a file name or name of a
-.I \%man\~page
-without further options.
-.
-But the option handling has many possibilities for creating special
-behaviors.
-.
-This can be done either in configuration files, with the shell
-environment variable
-.IR \%GROFFER_OPT ,
-or on the command line.
-.
-.
-.P
-The output can be generated and viewed in several different ways
-available for
-.IR \%groff .
-.
-This includes the
-X Window System-based
-.I \%groff
-program
-.BR \%gxditview (@MAN1EXT@),
-each
-.IR \%PostScript ,
-.IR \%PDF ,

-.SH "Option Details"
-.\" ====================================================================
-.
-The
-.B \%groffer
-program can usually be run with very few options.
-.
-But for special purposes, it supports many options.
-.
-These can be classified in 5 option classes.
-.
-.
-.P
-All short options of
-.B \%groffer
-are compatible with the short options of
-.BR \%groff (@MAN1EXT@).
-.
-All long options of
-.B \%groffer
-are compatible with the long options of
-.BR \%man (1).
-.
-.
-.P
-Arguments for long option names can be abbreviated in several ways.
-.
-First, the argument is checked whether it can be prolonged as is.
-.
-Furthermore, each minus sign
-.B \-
-is considered as a starting point for a new abbreviation.
-.
-This leads to a set of multiple abbreviations for a single argument.
-.
-For example,
-.B \-\-de\-n\-f
-can be used as an abbreviation for
-.BR \-\-debug\-not\-func ,
-but
-.B \-\-de\-n
-works as well.
-.
-If the abbreviation of the argument leads to several resulting options
-an error is raised.
-.
-.
-.P
-These abbreviations are only allowed in the environment variable
-.IR \%GROFFER_OPT ,
-but not in the configuration files.
-.
-In configuration, all long options must be exact.
-.
-.
-.\" ====================================================================
-.SS "groffer breaking options"
-.\" ====================================================================
-.
-As soon as one of these options is found on the command line it is
-executed, printed to standard output, and the running
-.B \%groffer
-is terminated thereafter.
-.
-All other arguments are ignored.
-.
-.
-.TP
-.B \-h\~\fR|\fB\~\-\-help
-Print help information with a short explanation of options to
-standard output.
-.
-.
-.TP
-.B \-v\~\fR|\fB\~\-\-version
-Print version information to standard output.
-.
-.
-.\" ====================================================================
-.SS "groffer mode options"
-.\" ====================================================================
-.
-The display mode and the viewer programs are determined by these
-options.
-.
-If none of these mode and viewer options is specified
-.B \%groffer
-tries to find a suitable display mode automatically.
-.
-The default modes are
-.IR "mode pdf" ,
-.IR "mode ps" ,
-.IR "mode html" ,
-.IR "mode xhtml" ,
-.IR "mode x" ,
-and
-.I "mode dvi"
-in the X Window System with different viewers and
-.I mode tty
-with device
-.I utf8
-under
-.B less
-on a terminal; other modes are tested if the programs for the main
-default mode do not exist.
-.
-.
-.P
-In the X Window System, many programs create their own window when
-called.
-.
-.B \%groffer
-can run these viewers as an independent program in the background.
-.
-As this does not work in text mode on a terminal (tty) there must be a
-way to know which viewers are X Window System-based graphical
-programs.
-.
-The
-.B \%groffer
-script has a small amount of information on some viewer names.
-.
-If a viewer argument of the command\-line chooses an element that is
-recognized as an X Window System-based program in this list, it is
-treated as a viewer that can run in the background.
-.
-Unrecognized viewers are not run in the background.
-.
-.
-.P
-For each mode, you are free to choose whatever viewer you want.
-.
-That need not be some graphical viewer suitable for this mode.
-.
-There is a chance to view the output source; for example, the
-combination of the options
-.B \-\-mode=ps
-and
-.B \-\-viewer=less
-shows the content of the
-.I PostScript
-output, the source code, with the pager
-.BR less .
-.
-.
-.TP
-.B \-\-auto
-Equivalent to
-.BR \-\-mode=auto .
-.
-.
-.TP
-.B \-\-default
-Reset all configuration from previously processed command-line options
-to the default values.
-.
-This is useful to wipe out all former options of the configuration, in
-.IR \%GROFFER_OPT ,
-and restart option processing using only the rest of the command line.
-.
-.
-.TP
-.BI \-\-default\-modes \ mode1,mode2,\*(EL
-Set the sequence of modes for
-.I \%auto\~mode
-to the comma separated list given in the argument.
-.
-See
-.B \-\-mode
-for details on modes.
-Display in the default manner; actually, this means to try the modes
-.IR x ,
-.IR ps ,
-and
-.I \%tty
-in this sequence.
-.
-.
-.
-.TP
-.B \-\-dvi
-Equivalent to

-.
-.TP
-.B auto
-Select the automatic determination of the display mode.
-.
-The sequence of modes that are tried can be set with the
-.B \-\-default\-modes
-option.
-.
-Useful for restoring the
-.I \%default\~mode
-when a different mode was specified before.
-.
-.
-.TP
-.B dvi
-Display formatted input in a
-.I \%DVI
-viewer program.
-.
-By default, the formatted input is displayed with the
-.BR \%xdvi (1)
-program.
-.

-.TP
-.B groff
-After the file determination, switch
-.B \%groffer
-to process the input like
-.BR \%groff (@MAN1EXT@)
-would do.
-.
-This disables the
-.I \%groffer
-viewing features.
-.
-.
-.TP
-.B html
-Translate the input into HTML format and display the result in a web
-browser program.
-.
-By default, the existence of a sequence of standard web browsers is
-tested, starting with

-is displayed with suitable viewer programs, such as
-.BR okular (1).
-.
-.
-.TP
-.B pdf2
-This is the traditional
-.IR "pdf mode" .
-.
-Sometimes this mode produces more correct output than the default

-using the PostScript device, then it is transformed into the PDF file
-format using
-.BR \%gs (1),
-or
-.BR ps2pdf (1).
-.
-If that's not possible, the
-.I PostScript mode (ps)
-is used instead.
-.
-Finally it is displayed using different viewer programs.
-.

-is
-.BR X75\-12 ,
-for
-.B 100dpi
-it is
-.BR X100 .
-.
-The corresponding
-.I "groff intermediate output"
-for the actual device is generated and the result is displayed.
-.
-For a resolution of
-.BR 100dpi ,
-the default width of the geometry of the display program is chosen to

-parameter is an argument that is not an option or option argument.
-.
-In
-.BR \%groffer ,
-.I \%filespec
-parameters are a file name or a template for searching
-.IR \%man\~pages .
-.
-These input sources are collected and composed into a single output
-file such as
-.B \%groff
-does.
-.
-.
-.P
-The strange \%\f(CRPOSIX\fP behavior to regard all arguments behind
-the first non-option argument as
-.I \%filespec
-arguments is ignored.
-.
-The \f(CRGNU\fP behavior to recognize options even when mixed with
-.I \%filespec
-arguments is used throughout.
-.
-But, as usual, the double minus argument
-.B \-\-
-ends the option handling and interprets all following arguments as
-.I \%filespec
-arguments; so the \%\f(CRPOSIX\fP behavior can be easily adopted.
-.
-.
-.P
-The options
-.B \-\-apropos*
-have a special handling of
-.I filespec
-arguments.
-.
-Each argument is taken as a search scheme of its own.
-.
-Also a regexp (regular expression) can be used in the filespec.
-.
-For example,
-.B groffer \-\-apropos '^gro.f$'
-searches
-.B groff
-in the
-.I man\~page
-name, while
-.B groffer \-\-apropos groff
-searches
-.B groff
-somewhere in the name or description of the
-.IR man\~pages .
-.
-.
-.P
-All other parts of
-.IR groffer ,
-such as the normal display or the output with
-.B \-\-whatis
-have a different scheme for
-.IR filespecs .
-No regular expressions are used for the arguments.
-.
-The
-.I filespec
-arguments are handled by the following scheme.
-.
-.
-.P
-It is necessary to know that on each system the
-.I \%man\~pages
-are sorted according to their content into several sections.
-.
-The
-.I classical man sections
-have a single-character name, either a digit from
-.B 1
-to
-.B 9
-or one of the characters
-.B n
-or
-.BR o .
-.
-.
-.P
-This can optionally be followed by a string, the so-called
-.IR extension .
-The
-.I extension
-allows the storage of several
-.I man\~pages
-with the same name in the same
-.IR section .
-But the
-.I extension
-is only rarely used; usually it is omitted.
-.
-Then the
-.I extensions
-are searched automatically by alphabet.
-.
-.
-.P
-In the following, we use the name
-.I section_extension
-for a word that consists of a single character
-.I section
-name or a
-.I section
-character that is followed by an
-.IR extension .
-.
-Each
-.I \%filespec
-parameter can have one of the following forms in decreasing sequence.
-.
-.
-.IP \*(BU 2m
-No
-.I \%filespec
-parameters means that
-.B \%groffer
-waits for standard input.
-.
-The minus option
-.B \-
-always stands for standard input; it can occur several times.
-.
-If you want to look up a
-.I \%man\~page
-called
-.B \-
-use the argument
-.BR man:\- .
-.
-.
-.IP \*(BU 2m
-Next a
-.I \%filespec
-is tested whether it is the path name of an existing file.
-.
-Otherwise it is assumed to be a searching pattern for a
-.IR \%man\~page .
-.
-.
-.IP \*(BU 2m
-.BI \%man: name ( section_extension ) ,
-.BI \%man: name . section_extension,
-.IB \%name ( section_extension ) ,
-or
-.IB \%name . section_extension
-search the \%man\~page
-.I \%name
-in \%man\~section and possibly extension of
-.IR \%section_extension .
-.
-.
-.IP \*(BU 2m
-Now
-.BI \%man: name
-searches for a
-.I \%man\~page
-in the lowest
-.I \%man\~section
-that has a document called
-.IR \%name .
-.
-.
-.IP \*(BU 2m
-.I \%section_extension\~name
-is a pattern of 2 arguments that originates from a strange argument
-parsing of the
-.B man
-program.
-.
-Again, this searches the man page
-.I name
-with
-.IR \%section_extension ,
-a combination of a
-.I section
-character optionally followed by an
-.IR extension .
-.
-.
-.IP \*(BU 2m
-We are left with the argument
-.I \%name
-which is not an existing file.
-.
-So this searches for the
-.I \%man\~page
-called
-.I \%name
-in the lowest
-.I \%man\~section
-that has a document for this name.
-.
-.
-.P
-Several file name arguments can be supplied.
-.
-They are mixed by
-.B \%groff
-into a single document.
-.
-Note that the set of option arguments must fit to all of these file
-arguments.

-.B \%groffer
-is called a
-.IR \%mode .

-program provides a search facility for
-.IR \%man\~pages .
-.
-All long options, all environment variables, and most of the

-aren't necessary any longer.
-.
-Additionally,
-.B \%groffer
-is a

-program; it wants to read
-.I roff
-source files and format them itself.
-.
-.
-.P
-The algorithm for retrieving the file for a
-.I \%man\~page
-needs first a set of directories.
-.
-This set starts with the so-called
-.I man\~path
-that is modified later on by adding names of
-.I operating system
-and
-.IR language .
-.
-This arising set is used for adding the section directories which
-contain the
-.I \%man\~page
-files.
-.
-.
-.P
-The

-is a list of directories that are separated by colon.
-.
-It is generated by the following methods.
-.
-.IP \*(BU 2m
-The environment variable
-.I \%MANPATH
-can be set.
-.
-.IP \*(BU 2m
-It can be read from the arguments of the environment variable

-.IP \*(BU 2m
-When no
-.I man\~path
-was set the
-.BR \%manpath (1)

-.
-.IP \*(BU 2m
-If this does not work a reasonable default path from
-.I $PATH
-is determined.
-.
-.
-.P
-We now have a starting set of directories.

-.
-.P
-Several names of
-.I operating systems
-can be given by appending their names, separated by a comma.
-.
-.

-.P
-but the two-letter code in

-is sufficient for most purposes.
-.
-If for a complicated

-formulation no
-.I \%man\~pages
-are found
-.B \%groffer
-searches the country part consisting of these first two characters as
-well.
-.
-.
-.P
-The actual directory set is copied thrice.
-.
-The
-.I language
-name is appended as subdirectory to each directory in the first copy
-of the actual directory set (this is only done when a language
-information is given).
-.
-Then the 2-letter abbreviation of the

-.
-The third copy of the directory set is kept unchanged (if no

-.I \%<name>
-is the name of the

-.P
-The

-is an addition to the section.
-.
-This postfix acts like a subsection.

-subdirectory.
-.
-It can be specified on the command line.
-.
-.
-.P
-On the other hand, the

-is just an information on how the file is compressed.
-.
-This is not important for the user, such that it cannot be specified
-on the command line.

-.P
-It is also possible to specify several

-by appending the single characters separated by colons.
-.

-.
-.
-.TP
-.I \%DISPLAY
-If set, this variable indicates that the X Window System is running.
-.
-Testing this variable decides on whether graphical or text output is
-generated.
-.
-This variable should not be changed by the user carelessly, but it can
-be used to start the graphical

-.\" ====================================================================
-.
-The
-.B \%groffer
-program can be preconfigured by two configuration files.
-.
-.
-.TP
-.B \%/etc/groff/groffer.conf
-System-wide configuration file for
-.BR \%groffer .
-.
-.
-.TP
-.B \%$HOME/.groff/groffer.conf
-User-specific configuration file for
-.BR \%groffer ,
-where
-.I \%$HOME
-denotes the user's home directory.
-.
-This file is called after the system-wide configuration file to enable
-overriding by the user.
-.
-.
-.P
-Both files are handled for the configuration, but the configuration
-file in
-.B /etc
-comes first; it is overwritten by the configuration file in the home
-directory; both configuration files are overwritten by the environment
-variable
-.IR \%GROFFER_OPT ;
-everything is overwritten by the command-line arguments.
-.
-.
-.P
-The configuration files contain options that should be called as
-default for every
-.B \%groffer
-run.
-.
-These options are written in lines such that each contains either a
-long option, a short option, or a short option cluster; each with or
-without an argument.
-.
-So each line with configuration information starts with a minus
-character
-.RB \[lq] \- \[rq];
-a line with a long option starts with two minus characters
-.RB \[lq] \-\- \[rq],
-a line with a short option or short option cluster starts with a
-single minus
-.RB \[lq] \- \[rq].
-.
-.
-.P
-The option names in the configuration files may not be abbreviated,
-they must be exact.
-.
-.
-.P
-The argument for a long option can be separated from the option name
-either by an equal sign
-.RB \[lq] = \[rq]
-or by whitespace, i.e.\& one or several space or tab characters.
-.
-An argument for a short option or short option cluster can be directly
-appended to the option name or separated by whitespace.
-.
-The end of an argument is the end of the line.
-.
-It is not allowed to use a shell environment variable in an option
-name or argument.
-.
-.
-.P
-It is not necessary to use quotes in an option or argument, except for
-empty arguments.
-.
-An empty argument can be provided by appending a pair of quotes to the
-separating equal sign or whitespace; with a short option, the
-separator can be omitted as well.
-.
-For a long option with a separating equal sign
-.RB \[lq] = \[rq],
-the pair of quotes can be omitted, thus ending the line with the
-separating equal sign.
-.
-All other quote characters are cancelled internally.
-.
-.
-.P
-In the configuration files, arbitrary whitespace is allowed at the
-beginning of each line, it is just ignored.
-.
-Each whitespace within a line is replaced by a single space character
-\[lq] \[rq] internally.
-.
-.
-.P
-All lines of the configuration lines that do not start
-with a minus character are ignored, such that comments starting with
-.RB \[lq] # \[rq]
-are possible.
-.
-So there are no shell commands in the configuration files.
-.
-.
-.P
-As an example, consider the following configuration file that can be
-used either in
-.B \%/etc/groff/groffer.conf
-or
-.B \%\s+2~\s0/.groff/groffer.conf .
-.

-.fi
-.hy
-.ft
-.
-.
-.P
-The lines starting with
-.B #
-are just ignored, so they act as command lines.
-.
-This configuration sets four
-.B \%groffer
-options (the lines starting with
-.RB \[lq] \- \[rq]).
-This has the following effects:
-.
-.
-.IP \*(BU 2m
-Use a text color of

-.\" ====================================================================
-.SH Compatibility
-.\" ====================================================================
-.
-The
-.B \%groffer
-program is written in Perl, the Perl version during writing was v5.8.8.
-.
-.
-.P
-.B \%groffer
-provides its own parser for command-line arguments that is compatible
-to both \%\f(CRPOSIX\fP
-.BR \%getopts (1)
-and \%\f(CRGNU\fP
-.BR \%getopt (1).
-It can handle option arguments and file names containing white space
-and a large set of special characters.
-.
-The following standard types of options are supported.
-.
-.
-.IP \*(BU 2m
-The option consisting of a single minus
-.B \-
-refers to standard input.
-.
-.
-.IP \*(BU 2m
-A single minus followed by characters refers to a single character
-option or a combination thereof; for example, the
-.B \%groffer
-short option combination
-.B \-Qmfoo
-is equivalent to
-.BR \-Q\~\-m\~foo .
-.
-.
-.IP \*(BU 2m
-Long options are options with names longer than one character; they
-are always preceded by a double minus.
-.
-An option argument can either go to the next command-line argument or
-be appended with an equal sign to the argument; for example,
-.B \-\-long=arg
-is equivalent to
-.BR \-\-long\~arg .
-.
-.
-.IP \*(BU 2m
-An argument of
-.B \-\-
-ends option parsing; all further command-line arguments are
-interpreted as
-.I \%filespec
-parameters, i.e.\& file names or constructs for searching
-.IR \%man\~pages ).
-.
-.
-.IP \*(BU 2m
-All command-line arguments that are neither options nor option
-arguments are interpreted as
-.I \%filespec
-parameters and stored until option parsing has finished.
-.
-For example, the command line
-.sp
-.EX
-\fIsh#\fR\~groffer file1 \-a \-o arg file2
-.EE
-.sp
-is equivalent to
-.sp
-.EX
-\fIsh#\fR\~groffer \-a \-o arg \-\- file1 file2
-.EE
-.sp
-.
-.P
-The free mixing of options and
-.I \%filespec
-parameters follows the GNU principle.
-.
-That does not fulfill the strange option behavior of \%\f(CRPOSIX\fP
-that ends option processing as soon as the first non-option argument
-has been reached.
-.
-The end of option processing can be forced by the option
-.RB \[lq] \-\- \[rq]
-anyway.

-Usage: groffer [option]... [filespec]...
-
-Display roff files, standard input, and/or Unix manual pages with an X
-Window viewer or in several text modes. All input is decompressed
-on-the-fly with all formats that gzip can handle.
-
-"filespec" is one of
- "filename" name of a readable file
- "-" for standard input
- "man:name(n)" man page "name" in section "n"
- "man:name.n" man page "name" in section "n"
- "man:name" man page "name" in first section found
- "name(n)" man page "name" in section "n"
- "name.n" man page "name" in section "n"
- "n name" man page "name" in section "n"
- "name" man page "name" in first section found
-where 'section' is a single character out of [1-9on], optionally followed
-by some more letters that are called the 'extension'.
-
--h --help print this usage message.
--T --device=name pass to groff using output device "name".
--v --version print version information.
--V display the groff execution pipe instead of formatting.
--X display with "gxditview" using groff -X.
--Z --ditroff --intermediate-output
- generate groff intermediate output without
- post-processing and viewing, like groff -Z.
-All other short options are interpreted as "groff" formatting options.
-
-The most important groffer long options are
-
---apropos=name start man's "apropos" program for "name".
---apropos-data=name
- "apropos" for "name" in man's data sections 4, 5, 7.
---apropos-devel=name
- "apropos" for "name" in development sections 2, 3, 9.
---apropos-progs=name
- "apropos" for "name" in man's program sections 1, 6, 8.
---auto choose mode automatically from the default mode list.
---default reset all options to the default value.
---default-modes=mode1,mode2,...
- set sequence of automatically tried modes.
---dvi display in a viewer for TeX device independent format.
---groff process like groff, disable viewing features.
---help display this helping output.
---html display in a web browser.
---man check file parameters first whether they are man pages.
---mode=auto|dvi|groff|html|pdf|ps|source|text|tty|utf8|www|x|X|xhtml
- choose display mode.
---no-man disable man-page facility.
---no-special disable --all, --apropos*, and --whatis
---pager=program preset the paging program for tty mode.
---pdf display in a PDF viewer.
---ps display in a Postscript viewer.
---source output as roff source.
---text output in a text device without a pager.
---to-stdout output the content of the mode file without display.
---tty display with a pager on text terminal even when in X.
---utf8 unicode text mode
---viewer choose a viewer for the actual device mode
---whatis display the file name and description of man pages
---www same as --html.
---x --X display with "gxditview" using an X* device.
---xhtml display html in XML mode using a web browser.
-
-The usual X Windows toolkit options transformed into GNU long options:
---background=color, --bd=size, --bg=color, --bordercolor=color,
---borderwidth=size, --bw=size, --display=Xdisplay, --fg=color,
---fn=font, --font=font, --foreground=color, --geometry=geom, --iconic,
---resolution=dpi, --rv, --title=text, --xrm=resource
-
-Long options of GNU "man":
---all, --ascii, --ditroff, --extension=suffix, --locale=language,
---local-file=name, --location, --manpath=dir1:dir2:...,
---sections=s1:s2:..., --systems=s1,s2,..., --where, ...
-
-Development options that are not useful for normal usage:
---debug, --debug-filenames, --debug-grog, --debug-keep, --debug-params,
---debug-tmpdir, --do-nothing, --print=text
-
-EOF
-
-# The following mode-viewer options were replaced by a single --viewer
-# option. The old options are only ignored:
-# --dvi-viewer=prog choose the viewer program for dvi mode.
-# --html-viewer=program
-# choose the web browser for html or xhtml mode.
-# --pdf-viewer=prog choose the viewer program for pdf mode.
-# --ps-viewer=prog choose the viewer program for ps mode.
-# --tty-viewer=prog select a pager for tty mode; same as --pager.
-# --www-viewer=prog same as --html-viewer
-# --x-viewer=prog choose viewer program for x mode (X mode).
-# --X-viewer=prog same as "--xviewer".
