      [Ralf S. Engelschall]

      [Ralf S. Engelschall]

   *) Port "sh.platform" to full POSIX 1003.1-2001 (SUSv3) compliance by
      replacing "head -1" with "sed -e 'q'" and "tail -1" with "sed -n -e '$p'".
      [Ralf S. Engelschall]

 Changes between 2.0b1 and 2.0b2 (17-Feb-2004 to 07-Apr-2004):

   *) Replace "tr 'x-' 'x_'" with "sed -e 's/-/_/g'" constructs
      because some tr(1) (at least Solaris' /usr/ucb/tr) go into endless
      loops on (incorrectly assumed) range constructs with no ends.
      [Armin Wolfermann <aw@osn.de>]

 Changes between 1.6.2 and 2.0b1 (02-Nov-2002 to 17-Feb-2004):

      with a completely new command "shtool platform" command.
      It distinguishes a Unix platform according to its hardware
      architecture and operating system. For both there is a class,
      product and technology identification. For each of those six
      identifications, there is a verbose, regular and concise version.
      [Ralf S. Engelschall]

   *) Upgraded to GNU Autoconf 2.58 environment.
      [Ralf S. Engelschall]

   *) Replace "[ x -o/-a x ]" constructs with "[ x ] ||/&& [ x ]"
      and "egrep"/"fgrep" constructs with compatible "grep" or "case"
      constructs. This way GNU shtool is now more POSIX 1003.1-2001
      compliant.
      [Paul Eggert <eggert@twinsun.com>]

   *) Make sure "shtool install -e ..." does not fail with "permission
      denied" on the internally created temporary files if the source
      file is not writeable to the current user. This occurs because
      cp(1) does not in all cases honor umask(2) (even without option
      -p) -- mainly if the source file is already owned by the current
      user (then the permissions are always copied). Hence an explicit
      "chmod u+w" is required if the "shtool install" substitution
      feature (option -e) is used.
      [Thomas Lotterer <thomas@lotterer.net>,
       Ralf S. Engelschall <rse@engelschall.com>]

   *) When patching a file with "shtool subst" try to make it
      writeable first in case it has permissions set differently.
      [Ralf S. Engelschall <rse@engelschall.com>]

   *) Fix calculation of effective source path in "shtool mkln" command
      for destination paths containing "/./" sequence and for source paths
      consisting of no directory parts at all.
      [Ralf S. Engelschall <rse@engelschall.com>,
       Michael Schloh v. Bennewitz <michael@schloh.com>]

   *) Use "env -i /bin/ls" construct in "shtool rotate" and "shtool slo"
      commands to make sure we have a consistent output not adjusted by
      some environment variables like LANG, LS_COLORS, LS_OPTIONS, etc.
      [Ralf S. Engelschall <rse@engelschall.com>,
       Manuel Hendel <manuel@hendel.net>]

   *) Make sure "shtool rotate" does still correctly determine
      the size of a file if its filename contains whitespaces.
      [Ralf S. Engelschall <rse@engelschall.com>,
       Bill Campbell <bill@celestial.com>]

   *) Consistently use "/bin/ls" instead of "ls" internally to avoid
      problems with other "ls" in PATH while still not becoming
      unportable (because "/bin/ls" is really on every reasonable
      Unix-style platform the "ls" command).
      [Ralf S. Engelschall <rse@engelschall.com>]

   *) Enhance %u, %U, %g and %G expansions of "shtool echo -e"
      by also trying the Solaris/Linux "getent" command.
      [Ralf S. Engelschall <rse@engelschall.com>,
       Christoph Schug <chris@schug.net>]

   *) Enhance %u, %U, %g and %G expansions of "shtool echo -e"
      by first trying to resolve via POSIX "id" command.
      [Ralf S. Engelschall <rse@engelschall.com>,
       Bill Campbell <bill@celestial.com>]

   *) Bump year in copyright messages to cover new year 2003.
      [Ralf S. Engelschall <rse@engelschall.com>]

   *) Fixed error exit in all commands by introducing an "shtool_exit"
      function (which correctly cleans up temporary files) and
      replacing all "exit" calls with "shtool_exit". THIS THE FIRST
      TIME INTRODUCED THE USAGE OF A SHELL FUNCTION TO THE SHTOOL CODE.
      This is known to break on _very_ anchient and broken Bourne-Shell
      implementations and is considered to be no longer a real problem
      in the year 2003. Especially there is no alternative way anyway.
      [Ralf S. Engelschall <rse@engelschall.com>]

   *) Fixed description of "shtool install -C" operation in manual page.
      [Stefan Seefeld <stefan@fresco.org>]

   *) Changed "shtool fixperm" to no longer set group writeability.
      [Ralf S. Engelschall, Michael van Elst <mlelstv@serpens.de>]

 Changes between 1.6.1 and 1.6.2 (12-Jul-2002 to 02-Nov-2002):

   *) Map "shtool install -d <dir> [...]" internally to "shtool mkdir
      -f -p -m 755 <dir> [...]" in order to support the BSD-style
      "install -d" variant.
      [Ralf S. Engelschall, Alan Eldridge <alane@geeksrus.net>]

   *) Add -o|--owner and -g|--group options to "shtool mkdir".
      [Ralf S. Engelschall]

   *) Fixed 'shtool scpp -f ...'. The arguments to option -f
      were not evaluated correctly.
      [Ralf S. Engelschall]

   *) Support bold font on 'cygwin' terminals.
      [Marcus Boerger <marcus.boerger@t-online.de>]

   *) Try the terminal 'init' sequence before 'reset' for bold mode
      restoring in order to make sure the terminal is not cleared.
      Additionally, fallback to a consistent no-bold mode.
      [Mirko Liss <mirko.liss@web.de>]

 Changes between 1.6.0 and 1.6.1 (01-Feb-2002 to 12-Jul-2002):

   *) Removed not-existing --min-size option from the usage
      of "shtool rotate". The name is just --size.
      [Thomas Linden <tom@izb.net>]

   *) Port to POSIX 1003.1-2001 (SUSv3) standard:
      sh.echo, sh.version: "head -1" -> "sed -e 'q'"
      sh.path: "sort -u | tail -1" -> "sort -r -u | sed -e q"
      sh.subst: diff -u1 -> diff -U1
      [Paul Eggert <eggert@twinsun.com>]

   *) Fixed various typos in shtool.pod.
      [Ralf S. Engelschall, Liones <liones@myrealbox.com>]

 Changes between 1.5.4 and 1.6.0 (14-Jun-2001 to 01-Feb-2002):

   *) Upgraded to GNU Autoconf 2.52 environment.
      [Ralf S. Engelschall]

   *) Fixed contained RPM specification (shtool.spec)
      [Ralf S. Engelschall]

   *) Added new command `shtool rotate [-v|--verbose] [-t|--trace]
      [-f|--force] [-n|--num-files <count>] [-s|--min-size <size>]
      [-c|--copy] [-r|--remove] [-a|--archive-dir <dir>] [-z|--compress
      [<tool>:]<level>] [-b|--background] [-d|--delay] [-p|--pad <len>]
      [-o|--owner <owner>] [-g|--group <group>] [-m|--mode <mode>]
      [-M|--migrate <cmd>] [-P|--prolog <cmd>] [-E|--epilog <cmd>]
      [<file> ...]'. This is a sophisticated command for rotating
      logfiles of daemons.
      [Ralf S. Engelschall]

   *) Added GNU long-option support (`--xxxx').
      [Ralf S. Engelschall]

   *) Cleaned up temporary file handling in `shtool path'.
      [Ralf S. Engelschall]

   *) Added NEWS file to source tree to comply to GNU standards.
      [Ralf S. Engelschall]

   *) Add new `shtool subst [-v] [-t] [-n] [-s] [-i] [-b<ext>]
      [-e<cmd>] [-f<cmd-file>] [<file>] [...]' command. This
      is a useful wrapper around sed(1).
      [Ralf S. Engelschall]

 Changes between 1.5.3 and 1.5.4 (19-Apr-2001 to 14-Jun-2001):

   *) Removed numerious trailing whitespaces from source files.
      [Ralf S. Engelschall]

   *) Updated shtool.spec file: DESTDIR support, indentation
      cleanups, etc.
      [Ralf S. Engelschall]

   *) Fixed typos in README.
      [Ralf S. Engelschall]

   *) Add missing entry for `tarball' to shtoolize.pod list.
      [Ralf S. Engelschall]

   *) Added %g (current group name) and %G (current group id)
      constructs to `shtool echo -e' command.
      [Ralf S. Engelschall]

   *) Fixed example of `shtool move' in shtool.pod
      [Ralf S. Engelschall]

   *) Fixed a bug in `shtool echo -e %d'
      [Ralf S. Engelschall, Christoph Schug <chris@schug.net>]

   *) Adjusted "make test" to also work under Cygwin environment.
      [Joerg Freudenberger <Joerg.Freudenberger@nbg9.siemens.de>]

 Changes between 1.5.2 and 1.5.3 (29-Feb-2001 to 19-Apr-2001):

   *) Added support for three usage lines to shtoolize.sh.
      [Ralf S. Engelschall]

   *) Fixed a few whitespace inconsistencies in shtool.pod
      and the usage line of `shtool tarball'.
      [Ralf S. Engelschall]

   *) Fix `shtool mkdir': option -m was only applied if
      option -p was present.
      [Ralf S. Engelschall]

 Changes between 1.5.1 and 1.5.2 (06-Jul-2000 to 29-Feb-2001):

   *) Fixed IFS usage in `shtool slo': `OIFS="$IFS" IFS="..."' is not
      portable, because some brain-dead Bourne-Shells (for instance /bin/sh
      under Solaris 2.8) evaluate from right-to-left instead of the usual and
      expected left-to-right. Fixed by adding a semicolon.
      [Christoph Schug <chris@schug.net>, Ralf S. Engelschall]

   *) Created a new `-e <sed-cmd>' option for `shtool install' which can
      be used one or multiple times to apply one or more sed(1) commands
      on-the-fly to installed files.
      [Ralf S. Engelschall]

   *) Kicked out the `-e <ext>' option of `shtool install', because it
      was a left-over from ancient days on non-POSIX systems and no longer
      is (or should be) of any use.
      [Ralf S. Engelschall]

   *) Adjusted copyright messages to cover year 2001, too.
      [Ralf S. Engelschall]

   *) Adjusted the shtool.spec a little bit.
      [Ralf S. Engelschall]

   *) Be extra paranoid and create temporary files with permissions of 0600.
      [Ralf S. Engelschall]

   *) Replaced a few too conservative `if [..] && [..]' with the faster
      but still portable `if [.. -a ..]'. Only make sure that `-a' and `-o'
      are not mixed in a single test (because this is unportable).
      [Ralf S. Engelschall]

   *) Fixed `shtool install': the default for option -m is 0755 in
      order to be consistent with the semantics of original BSD and
      GNU install commands.
      [Evgeny Stambulchik <fnevgeny@plasma-gate.weizmann.ac.il>]

   *) Added support to Makefile.in for DESTDIR variable. This allows
      easier rolling of installation tarballs (for instance from within
      RPM or similar facilities) by using "make install DESTDIR=/tmp/shtool".
      [Brad Smith <brad@comstyle.com>]

   *) Actually use the determined `find' command instead of the
      hard-coded one in `shtool tarball'.
      [Denis Barbier <barbier@imacs.polytechnique.fr>]

 Changes between 1.5.0 and 1.5.1 (01-Jul-2000 to 06-Jul-2000):

   *) Fixed hex value generation `shtool version': the `%X' printf
      format is not understood by all AWK flavors. So use the more
      portable `%x' instead and pass the result trough a `tr' filter.
      [Ralf S. Engelschall, Joe Meadows <joe.meadows@boeing.com>,
       Todd R. Stroup <tstroup@tomahawk.dartas.com>, Keith Minkler
       <kminkler@jabber.com>]

   *) Typo in shtool.pod
      [Ralf S. Engelschall]

   *) Add Python support to `shtool version'.
      [Benjamin Saller <case@appliedtheory.com>]

 Changes between 1.4.9 and 1.5.0 (16-Apr-2000 to 01-Jul-2000):

   *) Added global -r/--recreate option for generated shtool scripts which can
      be used to easily upgrade a script (the trick is that -r knows the list
      of modules which have to specified on the shtoolize command line).
      [Ralf S. Engelschall]

   *) Completely rewritten `shtool version':
      - new option -e for editing the new version interactively
      - unclean -i[sabpP] option variants are now gone
      - the calculated hex values (-dhex) are now really hex values
      - better calculated libtool values (-dlibtool)
      - the C and Perl version files are now using a structure instead
        of various single variables.
      - many other minor changes
      [Ralf S. Engelschall]

   *) Don't print `failed: 0/17' after a successful `make test'
      because it confused people too often.
      [Ralf S. Engelschall]

   *) In shtool.m4 check for shtool also in $ac_aux_dir.
      [Ralf S. Engelschall]

   *) Rewrote the `shtool path -m perl' handling, i.e., the way
      how to find the most reasonable Perl on a system. It now supports
      Perl 5.6.0 because we no longer parse `perl -v' output. Instead we
      base our assumptions on Perl's internal $] variable. Additionally
      the $PATH position and the executable name is now taken into
      account, too.
      [Ralf S. Engelschall]

   *) Fixed shtool.pod: `shtool path -m perl5 perl' is bogus, it has to
      be just `shtool path -m perl' because the "perl" argument is magic.
      [Ralf S. Engelschall]

   *) Fixed `here-document' handling in shtoolize: the whitespaces
      were incorrectly determined and so newlines were lost.
      [Ralf S. Engelschall]

   *) Allow `shtool install file [file ...] dir', i.e., multiple
      source files if target is a directory. This is especially useful
      for mass-installing files by using shell wildcards for the source.
      [Ralf S. Engelschall]

   *) Be compatible with SUSv2 and let `shtool mkdir -p' not complain
      if directory already exists.
      [Sascha Schumann <sascha@schumann.cx>]

 Changes between 1.4.8 and 1.4.9 (12-Mar-2000 to 16-Apr-2000):

   *) Added an `-f <filter>' option to `shtool scpp' which can be used to
      pre-filter all input files with one or more sed-expressions <filter>.
      [Ralf S. Engelschall]

   *) Try also `uname -x' in addition to `uname -m' in `shtool guessos'
      for backward compatibility to SVR4 platforms. Additionally changed
      the fallback vendor string from `whatever' to `unknown'.
      [Ralf S. Engelschall]

   *) Added `-p<prefix>' option to `shtool slo' to allow
      one to change the default variable prefix `SLO_' to <prefix>.
      [Ralf S. Engelschall]

   *) Speeded up `shtool echo -e "..%B..%b.."' by trying tput and tcout
      only if terminal is not a vt100, vt200 or an xterm (because for these
      three we have the escape sequences hard-coded).
      [Ralf S. Engelschall]

   *) Fixed various typos in the scripts.
      [Ralf S. Engelschall]

   *) Replaced old and ugly test for `test -x' in sh.fixperm, sh.path
      and sh.tarball with a faster, shorter and still sufficient test.
      [Ralf S. Engelschall]

   *) Added a RPM spec file shtool.spec which allows one to build RPM
      packages directly from the Shtool distribution tarball through a
      simple `rpm -tb shtool-1.X.Y.tar.gz' call.
      [Daniel Richard G. <straker@MIT.EDU>]

 Changes between 1.4.7 and 1.4.8 (24-Dec-1999 to 12-Mar-2000):

   *) Greatly speeded up option processing by moving option defaults
      directly into the sh.* scripts and by using a few faster parsing
      constructs.
      [Ralf S. Engelschall]

   *) Fixed a syntax error in the option parsing (there was a trailing
      quote character '"' in an 'eval' command). It fortunately and
      surprisingly never harmed the operation on any platforms.
      Additionally we now use sed instead of awk here.
      [Ralf S. Engelschall]

   *) Made shtool's command line related error messages more
      clear by distinguishing between options and commands.
      [Denis Barbier <barbier@imacs.polytechnique.fr>]

   *) Updated all copyright messages for year 2000.
      [Ralf S. Engelschall]

 Changes between 1.4.6 and 1.4.7 (05-Sep-1999 to 24-Dec-1999):

   *) Replaced the too generic (and this way slowed down processing)
      bang `!' mode in option parsing with a per-script local setup.
      [Denis Barbier <barbier@imacs.polytechnique.fr>]

   *) Fixed mkshadow command: it calculated the reverse path incorrectly
      if the destination path contained `../' elements.
      [Ralf S. Engelschall, Gil ?? <pg@sweng.stortek.com>]

   *) Ignore `_.SYMDEF' symbols in arx command.
      [Ralf S. Engelschall]

   *) Fixed `shtool echo' command for arguments containing whitespaces.
      [Denis Barbier <barbier@imacs.polytechnique.fr>]

 Changes between 1.4.5 and 1.4.6 (28-Jul-1999 to 05-Sep-1999):

   *) Fixed manual page sections in Makefile.in.
      [Denis Barbier <barbier@imacs.polytechnique.fr>]

   *) Accept `tarcust' in addition to `tardy' in sh.tarball.
      [Ralf S. Engelschall]

   *) Added hint to `shtoolize' to INSTALL document.
      [Denis Barbier <barbier@imacs.polytechnique.fr>]

   *) Added support for AmigaOS to sh.guessos
      [Ralf S. Engelschall]

   *) Replace bars (`|') by slashes (`/') in sh.guessos' fallback
      result string to avoid problems in GNU libtool.
      [Kriton Kyrimis <kyrimis@cti.gr>]

 Changes between 1.4.4 and 1.4.5 (17-Jul-1999 to 28-Jul-1999):

   *) Added a shtool.m4 which provides an AC_PROG_SHTOOL macro to GNU
      Autoconf. This is installed in $datadir/aclocal/ so it can be picked up
      by Autoconf's aclocal command.
      [Ralf S. Engelschall]

   *) Added `uninstall' target to Makefile.in
      [Ralf S. Engelschall]

   *) Source tree adjustments to comply more to the GNU standards: Added
      AUTHORS file; renamed CHANGES to ChangeLog and CREDITS to THANKS.
      [Ralf S. Engelschall]

   *) Added `make check' as an alias for `make test'
      [Ralf S. Engelschall]

 Changes between 1.4.3 and 1.4.4 (11-Jul-1999 to 17-Jul-1999):

   *) Added a new `shtool tarball' command for rolling
      nice distribution tarballs.
      [Ralf S. Engelschall]

   *) Fixed usage message of shtoolize.
      [Ralf S. Engelschall]

   *) Adjusted IRIX detection in sh.guessos.
      [Ralf S. Engelschall]

   *) Allow shtool to recognize symlinks to itself with the name of
      the shtool command like in `ln -s shtool install'.
      This is useful for emulation situations.
      [Paolo Bonzini <bonzini@gnu.org>, Ralf S. Engelschall]

 Changes between 1.4.2 and 1.4.3 (09-Jul-1999 to 11-Jul-1999):

   *) Fix the `a _directory_ named perl5 exists in $PATH' problem
      also for `shtool path -m perl'.
      [Justin Leonard Tripp <justin@ee.byu.edu>]

   *) Mention in the manual page that the order of documentation follows the
      order of the modules in the generated script and that this order is
      sorted by _topic_.
      [Ralf S. Engelschall]

 Changes between 1.4.1 and 1.4.2 (07-Jul-1999 to 09-Jul-1999):

   *) Removed residual shebang lines on sh.* scripts.
      [Gopal Narayanan <gopal@fcrao1.phast.umass.edu>]

   *) Enhanced sh.guessos for more granular GNU/Linux detection.  This
      especially fixes problems when using the guessed id with libtool.
      [Ralf S. Engelschall]

   *) Enhanced `shtool scpp': The generated function prototypes now
      no longer contain the argument names to avoid namespace conflicts
      [Ralf S. Engelschall]

   *) Fixed shtoolize.in: The chown() has to use $opt_o
      [Denis Barbier <barbier@imacs.polytechnique.fr>]

 Changes between 1.4.0 and 1.4.1 (02-Jul-1999 to 07-Jul-1999):

   *) Cleaned up usage messages.
      [Ralf S. Engelschall, Denis Barbier <barbier@imacs.polytechnique.fr>]

   *) Updated and cleaned up shtool.pod
      [Ralf S. Engelschall]

   *) Added shtool -d for enabling shell trace information.
      [Ralf S. Engelschall]

   *) Renamed shtool.gen to shtoolize.in and enhanced it to become the new
      build frontend which now is also installed and can be used by developers
      to build individual shtool scripts (which contain only a subset of the
      functionality in case the developer doesn't need all functionality in
      his source tree).
      [Denis Barbier <barbier@imacs.polytechnique.fr>, Ralf S. Engelschall]

   *) Made sh.scpp more robust on brain-dead platforms where their `awk' is to
      weak for the used Awk script.  Instead we now search for gawk, then nawk
      and finally for awk before using it.
      [Ralf S. Engelschall, Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>]

   *) Be more friendly to developers and require only Autoconf 2.12
      [Denis Barbier <barbier@imacs.polytechnique.fr>]

   *) Fixed typos related to `separate'.
      [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>]

 Changes between 1.3.3 and 1.4.0 (01-Jul-1999 to 02-Jul-1999):

   *) Fixed `shtool arx' command: it expected one argument too much,
      shifted one argument too much and wasn't aware of `arx x lib.a'.
      [Ralf S. Engelschall]

   *) Fixed `shtool echo -n' variant: Now Awk is only used as a fallback,
      because it complains about some \xx sequences and there is no $seo for
      Awk :-( [Ralf S. Engelschall]

   *) Added the first cut for a shtool test suite under `make test'.
      [Ralf S. Engelschall]

   *) Additionally try `tput sgr0' to reset bold mode in sh.echo
      [Denis Barbier <barbier@imacs.polytechnique.fr>]

   *) Fix initializations for `bptype' variable in sh.version
      [Denis Barbier <barbier@imacs.polytechnique.fr>]

   *) Globally cleaned up -v (verbose), -d (debug) and -t (trace) options:
      - Added -v (verbose) and -t (trace) options to "shtool move"
      - Added -v (verbose) and -t (trace) options to "shtool install"
      - Added -t (trace) option to "shtool mkdir"
      - Renamed -v option to -t (trace) option for "shtool mkln"
      - Renamed -d option to -t (trace) option for "shtool mkshadow"
      - Added -t (trace) option to "shtool fixperm"
      - Renamed -v option to -t (trace) option for "shtool arx"
      [Ralf S. Engelschall]

   *) Fixed a path construction bug in "shtool install" and
      added more error escapes
      [Ralf S. Engelschall]

   *) Removed remaining trailing whitespaces from scripts
      [Ralf S. Engelschall]

 Changes between 1.3.2 and 1.3.3 (28-Jun-1999 to 01-Jul-1999):

   *) Cleaned up usage of IFS and removed explicit default IFS
      [Ralf S. Engelschall]

   *) Removed trailing whitespaces from all scripts
      [Ralf S. Engelschall, Markus F.X.J. Oberhumer
      <markus.oberhumer@jk.uni-linz.ac.at>]

   *) Fixed error status handling in sh.move
      [Markus F.X.J. Oberhumer <markus.oberhumer@jk.uni-linz.ac.at>]

 Changes between 1.3.1 and 1.3.2 (28-Jun-1999 to 28-Jun-1999):

   *) Fixed a portability problem under SysV shells inside the source tree:
      the sh.xxxx scripts have to include sh.common via ``. ./sh.common''
      instead of just ``. sh.common'' in order to find sh.common in the
      source tree while bootstrapping.
      [Ralf S. Engelschall, Lars Hecking <lhecking@nmrc.ucc.ie>]
