3 * contrib/groffer/Makefile.sub (install): Reference groffer2.sh
4 as $(srcdir)/groffer2.sh, so it will install when building in a
5 different directory from the source.
7 ________________________________________________________________
9 * release of groffer 0.9.21
11 2005-08-02 Bernd Warken
16 - $_AT: New variable for `@'.
17 - @...@: Replace the @...@ constructs by variables _AT_..._AT.
18 These constructs are transformed by `make' to useful information.
19 Keep all of these constructs in the first part of groffer.sh. For
20 a run before a `make' call, the script sets these variables to
21 special values for testing purpose.
22 - $_GROFFER_LIBDIR: Variable pointing to the groffer library
23 directory @libdir@/groff/groffer.
25 ### Configuration files
28 - Add test for `$()' construct.
29 - Read and transform the configuration files and execute the
30 emerging commands. The `sed' script was heavily enlarged to
31 handle line with spaces and quotes. The emerging script is now
32 called by `eval', so no temporary file is needed.
33 - $_CONF_FILE_ETC, $_CONF_FILE_HOME: New variables for the config
35 - $_SQ, $_SP: Move variables for characters before the handling of
36 the configuration files. Rename $_SQUOTE to $_SQ and $_SPACE to
38 - $GROFFER_OPT: Remove cleaning of this variable before the
39 reading of the configuration files.
42 - main_init(): Remove the getting of the configuration files.
44 ### Rewrite the shell determination
47 - Get rid of all functions in `groffer.sh'. Rewrite the shell
48 determination with `` and $().
49 - --shell: Shortest abbreviation is `--sh'. Allow arguments for
51 - Allow an empty argument for --shell as shell name to overwrite a
52 specified shell; an empty shell name gets back to the default
54 - The shell determination now inludes the full handling of the
55 config files. The `--shell' option needs no longer a line
61 - Remove test of `unset'.
62 - Remove all calls of `unset'.
63 - Use one character names for all variables that are meant to be
67 - Move the test of `unset' to the testing of rudimentary shell
68 functionality without change.
70 ### Allow abbreviations for long options
73 - list_has_abbrev(): New function for checking a list having an
74 element with a given abbreviation.
75 - list_get_single_from_abbrev(): New function to retrieve the
76 element having a given abbreviation.
77 - list_from_cmd_line(): For an option abbreviation determine the
78 corresponding long option.
79 - From the man option lists remove the elements that are also in
81 - Allow abbreviation for the early test of --debug.
83 * groffer.sh: Allow abbreviation for the early test on --shell.
84 - get_opt_shell(): Rewrite _get_opt_shell() and the shell test
86 - test_on_shell(): Rename function _test_on_shell().
87 - $_SHELL: global variable for the shell to run groffer2.sh.
89 ### Get rid of `sh -c'
92 - main_display(), _do_display(): Remove the `sh -c' calls. Make
93 the cleanup working without it.
94 - _do_display(): Extend _do_display() such that it can be used for
96 - _make_pdf(): New subfunction of main_display() for running the
97 additional parts of pdf mode in _do_display().
98 - rm_file(), rm_file_with_debug(), rm_tree(): New functions for
99 removing files and directories.
104 - $_START_DIR: New variable to store the directory at the starting
106 - main_display(): Go to the groffer temporary directory to be able
107 to process internal `groff' data like pictures.
108 - clean_up(): Get back to the starting directory.
110 ### Compatibility with strange shells
113 - clean_up(): `zsh' and `posh' had difficulties with `eval'.
114 - is_*(): Add test on empty argument. Some shells return true on
115 `test -d' etc. with empty argument, while most shells return
117 - echo1(); New function to print single line `cat <<EOF'. Replace
118 all `echo x' by `echo1'.
119 - list_has_abbrev(), list_from_cmdline(): Correction.
120 - main_parse_MANOPT(): Repair and revise.
121 - --do-nothing: New option without output (for development).
122 - Rewrite rudimentary shell functionality near the beginning of
125 * groffer.sh, groffer2.sh:
126 - Remove `;' after the commands `if', `while', and `until'.
128 ### Debugging information
131 - $_DEBUG_PRINT_PARAMS: New variable for printing all parameters
132 from the config files, $GROFFER_OPT, and command line after they
133 have been transformed.
134 - $_DEBUG_PRINT_SHELL: New variable for printing the name of the
135 shell found in groff.sh.
136 - main(): Move the landmarks of main-*() into main().
138 ### Further checks and additions
140 * groffer.sh, groffer2.sh:
141 - $_PROGRAM_NAME: Replace this variable by `groffer'. The program
143 - $_GROFFER_RUN: Remove this variable. As `groffer.sh' or
144 `groffer' is no longer rerun, this variable is not necessary any
148 - main_set_resources(): Make the default viewers capable to use
149 arguments in the list.
150 - leave(): Add an argument for given exit code. Use it where
151 suitable in main_*().
152 - do_filearg(): Add error messages for non-existing files and man
154 - _do_opt_V(): New subfunction of main_display() to handle the
155 output for option `-V'. `groff -V' is greatly enlarged by
156 `groffer' specific information.
157 - register_title(): Handle file names with spaces. Replace spaces
159 - is_existing(): Add `test -c' for special files.
160 - usage(): Add `=arg' to the options with an argument. Add option
162 - kghostview: In the default viewer list, add option

193 2005-07-30 Bernd Warken
195 ### Split groffer.sh into two files groffer.sh and groffer2.sh.
198 - Remove the second part of this script. It is now in
200 - $_GROFFER2_SH: New variable to point to the installed position
201 of `groffer2.sh'. This position is presented using @libdir@.
203 * groffer2.sh: New script containing the second part of
204 groffer.sh. This script will be installed in the groffer library
205 directory @libdir@/groff/groffer, this might be
206 /usr/local/lib/groff/groffer/groffer2.sh for example.
209 - `groffer': Add replacement of @libdir@.
210 - `install_data': Add the installation of the groffer library
211 directory and groffer2.sh.
212 - `uninstall_sub': Delete the installed `groffer2.sh' and the
213 groffer library directory.

222 * release of groffer 0.9.19
224 2005-07-07 Bernd Warken
226 * groffer.sh: extensions
227 - `mode x': Mode for the equivalent options `--x', `--mode x',
228 `--X' `--mode X', and the default mode. The default assumes a
229 resolution of 75 dpi. The default device for a resolution of 75
230 dpi is `X75-12', the default device for a resolution of 100 dpi is
231 `X100'. The default geometry for the resolution of 100 dpi is set
232 to the width 800 dpi.
233 - `mode X': New mode for option -X only.
234 - `-V': Extent the `groff' output of -V by `groffer' specific
235 information (in main_display()).
236 - register_file(): Replace title `-' by `stdin'.
237 - $_DEBUG_KEEP_FILES: If set to `yes' the files in the temporary
238 directory are not deleted before the end trap.
240 * groffer.sh: get `zsh' to work as well
241 - tmp_create(): Use `: >file' for generating an empty file.
242 - rmdir: Replace `rmdir' by `rm -f -r'.
243 - eval: Add `eval' to many commands with variable arguments.
245 * groffer.sh: repair `debug'
246 - Print all debug output to stderr.
247 - $_FUNC_STACK: Built function call stack even when $_DEBUG is not
248 set. Now the arguments are not added.
249 - $_DEBUG: If set to `yes' print 3 call stack events: the function
250 that is added with its arguments is printed with `+++ '
251 (func_push()); the call stack after the addition is printed with
252 `>>> ' (func_push()); the call stack after the removing is printed
253 with `<<< ' (func_pop()).
254 - error(): Always print the function call stack on errors.
256 * groffer.sh: Corrections
257 - $_groffer_run: Rename to $_GROFFER_RUN.
258 - $unset: Rename to $_UNSET.
259 - Repair test of `unset'.
260 - Repair test for `--shell'. The script is now rerun under the
261 shell specified in the option argument. This can increase the
264 * README_SH: `zsh' now works.
267 - Reformulate the information for the `groffer' specific details
269 - Add information on the debug process.
270 - Add information on the default devices in `x mode'.
273 ________________________________________________________________
274 * release of groffer 0.9.18
276 2005-07-01 Bernd Warken
278 * groffer.sh: further shell compatibility
279 - `echo': Remove options and possible options of `echo' by
280 preceding the argument with a character `x' that is removed by
281 `sed' or replace `echo' by `cat <<EOF'. `echo -n' seems to be not
282 portable, so it is omitted.
283 - `for': Remove `;' from within `for' (because of ksh).
284 - `ls': Old UNIX systems echoed the error message to standard
285 output. So handle the output with `sed'. If the output contains
286 `not found' map it to an empty string.
287 - `true': Replace `true' by command `:'. Remove test of `true'
288 (because `ash' refuses the redefinition of builtins even in an
289 unreachable `if' branch).
290 - `false': Remove test of `false'; it isn't used any more.
291 - `test': As `test -e' does not exist in Solaris 2.5 replace it by
292 `test -f || test -d'.
293 - `unset': `unset' is said to be not portable. As `ash' protests
294 against the definition of the function `unset()' in the test of
295 `unset' replace the test by defining `$unset' to `unset' if it
296 exists and to `:' otherwise. Use `eval $unset' instead of the
297 direct command `unset'.
298 - _get_opt_shell(): Replace `for' loop with `shift' by `while'.
299 - man_search_section(): Replace `for f in filename*' by a test on
300 the existence of `filename*'.
301 - `zsh' interprets `$...' as `"$..."'. So `eval' must be called;
302 This cannot be used in `for i in $f', so it must be rewritten as
303 `for i in $(eval set x $f; shift; echo "$@")'
306 - `--X', `--x', `--mode=X', `--mode=x': Make these options
307 equivalent to choosing an X device by setting `-TX75-12'. `-X' is
308 still equivalent to `groff -X'.
309 - main_init(): Choose the name of the temporary file by adding a
310 number using `expr' if it exists and cannot be removed.
311 - main_parse_args():Repair some options by replacing `$mpa_mode'
313 - catz(): Rename it to cat_z() to avoid problem with existing
315 - where(): Rename to where_is().
316 - $_CONFFILES: Rename to $_CONF_FILES.
317 - $_HAS_BZIP: export and preset it.
320 - Document the `X mode' changes.
321 - Add `@g@' to `troff'.
323 * README, README_SH, TODO:
324 - Add date line `Latest update:'.
325 - Add `...' quoting to essential terms.
326 - Add Emacs mode at the end.
329 - Add documentation on the above compatibility changes.
330 - Add documentation on used commands.
331 - Mention the tested shells.
336 ________________________________________________________________
337 * release of groffer 0.9.17
339 2005-06-23 Bernd Warken
341 * groffer.sh: get rid of `local' in functions (it is not POSIX)
342 - Replace local variables by variable names with a special prefix
343 that is an abbreviation of the corresponding function name (quasi-
345 - Unset the quasi-local function variables before returning.
346 - _t_e_s_t_f_u_n_c_(): Remove tests for local and global
348 - Add quasi-local variables for saving the content of
349 single-character variables.
350 - Remove some unused local and global variables.
351 - Several variables were forgotten to make local. They are now
354 * groffer.sh: other corrections
355 - $return_var: New function (after `eval') for an arbitrary
357 - obj*(): Add return modes.
358 - Rewrite tests for `true' and `false'.
359 - Add function names to error calls where it was forgotten.
360 - `for': Replace `for x in "$@"' by `for x'.
361 - `set': Replace `set -- ...' by `set x ...; shift'.
362 - `sed': Replace `\|.*|s|...|...|' by `s|...|...|'.
365 - Add information on the removing of `local'.
366 - New section for non-POSIX shell restrictions.

380 * groffer.man: Add section `BUGS'.
383 - Add compatibility information.
384 - Correct documentation for function arguments.
386 2005-06-18 Keith Marshall
388 * groffer.sh: $_NULL_DEV: Replace /dev/null by $_NULL_DEV which is
389 either /dev/null or NUL if /dev/null does not exist.
391 2005-06-17 Zvezdan Petkovic
393 * Makefile.sub: $(RM): Define it to `rm -f' because not all `make'
394 programs have it predefined.

424 - Move some parts on usage from README_SH to README.
425 - Reformulate several parts of both files.
427 * groffer.man: update
429 2005-05-14 Keith Marshall
432 - first line: Add space to `#! /bin/sh'.
434 2004-11-15 Bernd Warken
435 ________________________________________________________________
436 * release of groffer 0.9.12
439 - main_init(): Rewriting of the creation of the temporary
440 directory to ensure that it cannot be made writable apart from the
441 user. If the directory already exists and cannot be removed then
442 append `X' to the directory name.
443 - is_non_empty_file(): fix it to use POSIX `test -s'.
444 - is_existing(): new function.
445 - POSIX `rm -f -r': use this in `clean_up()' and `main_init()'.
446 - `--macro-file': remove this unused long option.

457 subsection in their apropos output.
459 2004-06-02 Bernd Warken
460 ________________________________________________________________
461 * release of groffer 0.9.10
464 - Remove automatic call of `ash' due to inconsistencies of
465 different ash versions.
466 - In the first run, add recognition of `--shell' lines in the
467 groffer configuration files. To configure an external shell in
468 a configuration file, a line starting with `--shell' is
470 - list_from_cmdline(): Simplify the arguments.
471 - As $POSIXLY_CORRECT is internally set to `y' by some GNU
472 `/bin/sh' shells the following 2 fixes are necessary:
473 -- `sed': Empty patterns are not allowed with $POSIXLY_CORRECT
474 set; so move the address information before the `s' command to the
475 pattern after the command, and write `.*' to the address field.
476 -- list_from_cmdline(): Remove the strange $POSIXLY_CORRECT style
477 to finish the option processing after the first non-option
478 argument; use the flexible GNU mixing of options and file names
482 - Remove any hints on `ash'.
483 - Add minus line behavior of `--shell' for configuration and add a
484 corresponding example.
485 - Update the information on $POSIXLY_CORRECT.
487 2004-05-29 Bernd Warken

525 2004-04-27 Bernd Warken
526 ________________________________________________________________
527 * release of groffer 0.9.6
529 This version replaces the license of all files except ChangeLog of
530 the groffer source to the GNU General Public License (GPL) of the
531 version described in files COPYING and LICENSE in the groff top
535 Changement from the GNU Free Documentation License (FDL) to

546 which is weaker than the GPL, but has its flavor.
548 2004-04-24 Bernd Warken
549 ________________________________________________________________
550 * release of groffer 0.9.5
552 This version is a rewrite of groffer in many parts, but it is kept
553 in the old single script style.
555 Overview of new options:
556 --text, --mode text, --tty-viewer,
557 --X, --mode X, --X-viewer, --html, --mode html, --html-view,
558 --apropos-data, --apropos-devel, --apropos-progs
561 <groffer-source>/README_SH
564 ******* Extension of the `apropos' handling
566 The output of man's `apropos' has grown immensely meanwhile, so it
567 has become inefficient. Now `groffer' provides new options to get
568 the a selected information from this output.
571 `--apropos-progs': new option for displaying only information
572 on programs (man page sections 1, 6, and 8)
573 `--apropos-data': new option for displaying only information
574 on documented data (man page sections 4, 5 and 7)
575 `--apropos-devel': new option for displaying only information
576 on development documentation (man page sections 2, 3 and 9)
577 `--apropos': still displays just the output of man's `apropos'
579 - Specify all of these options as a single argument option; that
580 makes groffer's `--apropos' option slightly different because
581 the corresponding `man' option does not have arguments, but takes
582 all file arguments as apropos targets. So just ignore the `man'
583 options `-k' and `--apropos' in the parsing of $MANOPT.
584 - Exit after processing one `apropos' call.
587 ******* Quasi object oriented function arguments
589 An object is the name of an environment variable. The value of
590 this variable contains the object's content. This allows to
591 specify function arguments and the calling syntax in a simpler way
592 by letting the first argument be a variable name, usable for input
595 Such an object type is `list', the string value of a shell
596 variable arranged in space-separated single-quoted elements, such
597 as $GROFFER_OPT internally.
600 - Remove list_from_args(), list_element_from_arg()
601 list_from_lists(), list_length(), and list_prepend().
602 They can be replaced by list_append().
603 - All list*() functions are rearranged such that the first
604 argument is a list object, the name of a variable.
607 ******* Simplification of configuration files
609 The new syntax of the groffer configuration files is
610 - all lines starting with a `-' character are interpreted as
611 command line options for all calls of groffer; they are collected
612 and prepended to the actual value of $GROFFER_OPT; optional
613 spaces at the beginning.of the line are omitted.
614 - all other lines are interpreted as a shell command and executed
615 in the current shell of the groffer call.
618 - The command line and the external environment variables such as
619 $GROFFER_OPT of the groffer call have the highest precedence.
620 - This is overwritten by the configuration file in the user's home
622 - The system configuration file in /etc has the lowest
626 The configuration files are now called after the determination of
627 the temporary files in main_init().
630 ******* Script file name
632 The file name of the script is needed for the several calls during
633 the search for the optimal shell.
636 - $_GROFFER_SH: replace $_this by $_GROFFER_SH and use $0 for
637 determining the file name of the script for the following calls,
638 instead of the cumbersome @BINDIR@ construction.
639 - Force the script to be called as an executable file, so $0 must
640 contain the program name.
643 ******* Improved temporary file names
645 Just like groff, groffer mixes all file parameters into a single
646 output file. Its name is now constructed as a comma-separated
647 list built from the file name arguments without a leading comma.
648 So a leading comma can be used for the internal temporary file
652 - $_OUTPUT_FILE_NAME: new global variable as basis for the output
653 file name; it is set in main_set_resources().
654 - tmp_create(): use `,name' for temporary files different from
655 output file because the output file name does not start with a
656 comma. `$$' is not needed anymore.
657 - main_display(): simplification of $_modefile in _do_display()
658 and single display modes.
659 - Add extension `.html' to output file name in html mode.
660 - base_name(): correction for strange positions of `/'.
666 - Set the main default mode to `x' with groff's X Window viewer
668 - Allow 'x' and 'X' in `--mode' for the X Window mode; the same
669 for `--x' and `X', `--x-viewer' and `--X-viewer'.
670 - Make groff's `-X' equivalent to `mode X'.
671 - Fix `--auto', `--mode auto', and `--default-modes'.
672 - `html' mode: new mode equivalent to `www', add `konqueror' and
674 - `pdf' mode: fix zoom options for pdf-viewer `xpdf' in
675 main_set_resources(); in main_display() fix the display structure.
676 - Set default X Window resolution to 75dpi. This is not optimal,
677 but with a higher value the options and resources for some viewers
679 `--text' and `--mode text': new option for text output without a

740 ________________________________________________________________
741 * release of groffer 0.9.4
743 * groffer.sh: corrections for some restrictive shells
744 - Possible exit codes in actual `ash' are between 0 and 63. To
745 handle even deeper restrictions, use 7 as maximal code instead
746 of 255 as replacement for error -1.

842 - Remove the 'sed' complaints.
844 2002-07-15 Bernd Warken

847 - This improves the performance of the shell programming parts
848 and shortens the groffer script by about 5%.
849 - Remove functions: string_del_append(), string_del_leading(),
850 string_del_trailing(), string_flatten(), string_get_before(),

862 the shell specified in the argument of `--shell'.
863 - If no shell was specified at run-time, `ash' is tried first;
864 if `ash' is not available continue with the shell with which
865 groffer was called from the command line, or with the shell
866 name in the first line of the script, actually `/bin/sh'.
868 2002-07-12 Bernd Warken
869 ________________________________________________________________
870 * fixes for groffer 0.9.0
872 * groffer.sh: enhance version information
873 `groffer -v|--version' now print:
874 - groffer's version number and date
875 - the string `is part of '
876 - groff's version information (version number and copyright),
877 but not groff's `called subprograms' information.
879 * groffer.sh: minor fixes
880 - Fix the argument parser to process argument `-' correctly.
881 - Some display programs have trouble with empty input; feed a
882 line consisting of a single space character in this case for
883 all display modes (not for source or groff modes).
886 fix entry `shoop' (not 'shopt').
888 2002-06-28 Bernd Warken
889 ________________________________________________________________
890 * release of groffer 0.9.0
892 * groffer.sh: new mode `pdf'
893 - PDF (Portable Document Format):
894 -> Transform groff `ps' output into pdf using `gs'.
895 -> Pro: PDF viewers provide text searching (!).
896 -> Con: the transformation is quite slow.
897 -> Not suitable as an auto mode.
898 - New options `--pdf', `--pdf-viewer', `--mode pdf'.
899 - Standard pdf viewers `xpdf' and `acroread'.
900 - For `xpdf', choose zoom `z 3' for 100 dpi, `z 2' for 75 dpi.
902 * groffer.sh: support bzip2 decompression
903 - add test for `bzip2' with necessary options

941 - Disabled by default; enabled by environment variables.
942 - Add landmark() to catch typos with quotes.
943 - Add a function call stack for suitable functions; implemented
944 as within the argument checker func_check().
945 - This implies the need to provide `return' with some clean-up
946 facility; implemented as `eval "$_return_..."'.
947 - Add option `--debug' to enable debugging at run-time.
948 - Actually, the groffer script uses only shell builtins found
949 in `ash' (a subset of POSIX) and POSIX `sed' as the only
950 external shell utility.
952 * groffer.sh: customization of viewers
953 - In `groff' mode, the groffer viewing facilities are disabled.
954 - The postprocessor option `-P' costumizes the viewer only in
955 some situations in the `groff' mode, so a new infrastructure
956 for viewer customization is necessary.
957 - Allow to specify arguments to the viewer programs specified
959 - Implement some of the essential X Toolkit resource options in
960 groffer, but with use a leading double minus.

963 -> `--bw': set border width.
964 -> `--display': set X display.
965 -> `--geometry': set size and position of viewer window.

976 -> `--ps-viewer' sets the Postscript viewer.
977 - New mode `www' (`--www') for displaying in a web browser:
978 -> default browsers: mozilla,netscape,opera,amaya,arena;
979 -> `--www-viewer' sets the web browser.
980 - New dvi mode (`--dvi'); default viewer `xdvi':
981 -> default viewers: xdvi,dvilx;
982 -> `--dvi-viewer' sets the dvi viewer.
984 -> active if no other mode is given or by new option `--auto';
985 -> selects from a sequence of modes that are tested until one
987 -> the default mode sequence is actually `ps', `x', `tty'.
988 -> `--default-modes' sets this mode sequence as a comma
989 separated string of program names, optionally each one
992 -> process input like groff, ignore viewing options.
993 -> activated by new option `--groff'.
994 -> automatically active with one of `-V', `-X', `-Z'.
996 -> allow several text devices.
998 - Reorganize the mode management:
999 -> new mode setting option `--mode'.
1000 -> logically separate source, groff, and display modes.
1001 -> intermediate output mode is now part of mode groff; remove
1002 any special features around `-Z'.
1003 - Update usage() to reflect the new option structure.
1005 * groffer.sh: add configuration files
1006 - `/etc/groff/groffer.conf' system-wide configuration.
1007 - `${HOME}/.groff/groffer.conf' user configuration.
1008 - The configuration file are shell scripts for now; later
1009 implementations can identify this from the `#! /bin/sh' line.
1011 * groffer.sh: new data structure `list':
1012 - Implement a `list' data structure as a string consisting of
1013 single-quoted elements, separated by a space character;
1014 embedded single-quotes are escaped.
1016 * groffer.sh: new option parser based on `list':
1017 - Write new option parser based on `list', compatible to both
1018 POSIX getopts() and GNU getopt().
1019 - Long options are now available on GNU and non-GNU systems.
1020 - Get rid of POSIX getopts() and GNU getopt().
1021 - the `-W--longopt' construct is now obsolete; remove it.
1022 - add test/function for `unset'.
1023 - Option strings are now implemented as `list's in order to
1024 allow unusual characters in options.
1025 - Parse $MANOPT first; translate essential arguments into
1029 - determine prompt length for `.Shell_cmd'* dynamically.
1030 - naming scheme for static strings and registers changed to
1031 `namespace:macro.variable'.
1034 2002-06-16 Werner Lemberg <wl@gnu.org>
1037 Implement man option `--ascii' by `-mtty-char'.
1040 2002-05-31 Werner LEMBERG <wl@gnu.org>
1042 * groffer.man (@.Shell_cmd_width):
1043 Increase to 4m (we use `sh#' as the prompt).
1046 2002-05-31 Bernd Warken
1047 ________________________________________________________________
1048 * release of groffer 0.7
1050 * groffer.sh: remove incompatibilities with the `ash' shell:
1051 - do not use `!command':
1053 -> write `_not_' equivalents for some functions
1054 - do not use `[^]' in `case':
1055 -> restructure some functions.
1056 - only single-character names for loop variables:
1057 -> spoils the paradigm of leading `_' for local variables.
1058 - spurious trouble with `for i in ${var}':
1059 -> use `eval set -- ${var}' and `for i in "$@"'
1060 - do not change or use $IFS:
1061 -> define new functions string_split() and `path_split()'.
1062 -> result must be processed by `eval set --'.
1063 -> solve conflicts with existing positional parameters.
1064 - trouble with exporting external `$GROFF_*' variables:
1065 -> hope that they were exported in the calling shell.
1066 - not smart about additional blanks:
1067 -> remove unnecessary white space.
1069 * groffer.sh: improve run-time speed:
1070 - `ash' more than doubles the speed of `bash'.
1071 - speed-up `man_setup()'.
1074 2002-05-30 Werner Lemberg <wl@gnu.org>
1077 - remove some wrong `\:'.
1078 - rename macro names that start with a `[' (clashes with refer).
