* keychain 2.8.2 (06 Nov 2015)

  Summary: Support new ssh features, bug fix release.

  Support for new hash algorithms (Ben Boeckel)

  Remove bashisms (Daniel Hertz)

  Various optimizations (Daniel Hahler)

  --timeout option now gets passed to agent, doc fixes (Andrew Bezella, Emil
  Lundberg)

  RPM, Makefile fixes (Mike Frysinger)

* keychain 2.8.1 (29 May 2015)

  Summary: POSIX compatibility and bug fix release.

  Only set PATH to a standard value if PATH is not set. Otherwise, do not
  modify.

  Makefile Cygwin and RPM spec fixes (thanks Luke Bakken and Ricardo Silva)

  Confhost fixes. Deprecate in_path. Use command -v instead.

  Find_pids: Modify "ps" call to work with non-GNU ps. (Bryan Drewery)

  Re-introduce POSIX compatibility (remove shopt.) (vaeth)

* keychain 2.8.0 (21 Mar 2015)

  Support for OpenSSH 6.8 fingerprints.
  Support for GnuPG 2.1.0.

  Handle private keys that are symlinks, even if the associated public key is
  in the target directory rather than alongside the symlink.

  Allow private keys to have extensions, such as foo.priv. When looking for
  matching public keys, look for foo.priv.pub, but also strip extension and
  look for foo.pub if foo.priv.pub doesn't exist.

  Initial support for --list/-l option to list SSH keys.

  Updated docs for fish shell usage.

* keychain 2.7.2_beta1 (07 July 2014)

  Various changes and updates:

  Fixes for fish from Marc Joliet.
  
  Keychain will default to start only ssh-agent unless GPG is explicitly
  updated using --agents. 

  Write ~/.gpg-agent-info when launching gpg-agent - fix from Thomas Spura.

  Add support for injecting agents into systemd (Ben Boeckel)

  Add support for --query option (Ben Boeckel)

  Add --absolute flag, allowing user to set a full path without getting a
  .keychain suffix automatically appended.

  Add --confhost option to scan ~/.ssh/config file to locate private key
  path specified there.

* keychain 2.7.1 (07 May 2010)

  07 May 2010; Daniel Robbins <drobbins@funtoo.org>: Addition of a "make
  clean" target. removal of runtests as it is currently broken.

  07 May 2010; Daniel Robbins <drobbins@funtoo.org>: New release process in
  Makefile and release.sh - keychain release tarball will now contain
  pre-generated keychain, keychain.1 and keychain.spec so that users do not
  need to run "make". Updated README.rst to refer to the "source code" as
  a "release archive" since it contains both source code and ready-to-go
  script and man page.

  14 Apr 2010; Daniel Robbins <drobbins@funtoo.org>: GPG fix from Gentoo bug
  203871; from Frederic Bathelery. This fix will fix the issue with pinentry
  starting in the background and not showing up in the terminal.

  20 Feb 2010; Daniel Robbins <drobbins@funtoo.org>: MacOS X documentation fix
  from James Turnbull.

* keychain 2.7.0 (23 Oct 2009)

  23 Oct 2009; Daniel Robbins <drobbins@funtoo.org>: updated README.rst with
  2.7.0 and MacOS X package update.

  18 Oct 2009; Daniel Robbins <drobbins@funtoo.org>: lockfile() replacement
  from Parallels Inc. OpenVZ code, takelock() rewrite, resulting in ~100 line
  code savings. Default lock timeout set to 5 seconds, and now keychain will try
  to forcefully acquire the lock if the timeout aborts, rather than simply
  failing and aborting.

  30 Sep 2009; Daniel Robbins <drobbins@funtoo.org>: MacOS X/BSD improvements:
  fix sed call in Makefile for MacOS X and presumably other *BSD environments,
  Rename COPYING to COPYING.txt, slight COPYING.txt formatting changes to
  allow license to display more cleanly from MacOS X .pkg automated install.
  Fixed POD errors (removed '=end').

  29 Sep 2009; Daniel Robbins <drobbins@funtoo.org>: disable "Identity added"
  messages when --quiet is specified (Gentoo bug #250328, thanks to Richard
  Laager,) --help will print output to stdout (Gentoo bug #196060, thanks to
  Elan Ruusamäe,) output cleanup and colorization changes - moving away from
  blue and over to cyan as it displays better terminals with black background.
  Also some additional colorization. Version bump to 2.6.10.

* keychain 2.6.9 (26 Jul 2009)

  26 Jul 2009; Daniel Robbins <drobbins@funtoo.org>: Close Gentoo bug 222953
  from Bernd Petrovitsch to fix potential issues with GNU grep, Mac OS X color
  fix when called with --eval from Aron Griffis <agriffis@n01se.net>, Perl
  5.10 Makefile fix from Aron Griffis <agriffis@n01se.net>. Transition README
  to README.rst (reStructuredText). Updated maintainership information.
  Simplified default output ( --version or --help now required to show
  version, copyright and license information.)

* keychain 2.6.8 (24 Oct 2006)

  24 Oct 2006; Aron Griffis <agriffis@gentoo.org>:
  Save LC_ALL for gpg invocation so that pinentry-curses works.  This affected
  peper and kloeri, though it seems to work for me in any case.

* keychain 2.6.7 (24 Oct 2006)

  24 Oct 2006; Aron Griffis <agriffis@gentoo.org>:
  Prevent gpg_listmissing from accidentally loading keys

* keychain 2.6.6 (08 Sep 2006)

  08 Sep 2006; Aron Griffis <agriffis@gentoo.org>:
  Make --lockwait -1 mean forever.  Previously 0 meant forever but was
  undocumented.  Add more locking regression tests #137981

* keychain 2.6.5 (08 Sep 2006)

  08 Sep 2006; Aron Griffis <agriffis@gentoo.org>:
  Break out of loop when empty lockfile can't be removed #127471.  Add locking
  regression tests:
    100_lock_stale 101_lock_held 102_lock_empty 103_lock_empty_cant_remove

* keychain 2.6.4 (08 Sep 2006)

  08 Sep 2006; Aron Griffis <agriffis@gentoo.org>:
  Add validinherit function so that validity of SSH_AUTH_SOCK and friends can be
  validated from startagent rather than up front.  The advantage is that warning
  messages aren't emitted unnecessarily when --inherit *-once.
  Fix --eval for fish, and add new testcases: 
    053_start_with_--eval_ksh
    054_start_with_--eval_fish 
    055_start_with_--eval_csh

* keychain 2.6.3 (07 Sep 2006)

  07 Sep 2006; Aron Griffis <agriffis@gentoo.org>:
  Support fish: http://roo.no-ip.org/fish/
  Thanks to Ilkka Poutanen for the patch.

* keychain 2.6.2 (20 Mar 2006)

  20 Mar 2006; Aron Griffis <agriffis@gentoo.org>:
  Add --confirm option and corresponding regression tests for Debian bug 296382.
  Thanks to Liyang HU for the patch.  Also add initialization for $ssh_timeout
  which was being inherited from the environment and add regression tests for
  --timeout

* keychain 2.6.1 (10 Oct 2005)

  10 Oct 2005; Aron Griffis <agriffis@gentoo.org>:
  Change "unset evalopt" to "evalopt=false" and run through *all* the regression
  tests instead of just the new ones.  *sigh*

* keychain 2.6.0 (10 Oct 2005)

  10 Oct 2005; Aron Griffis <agriffis@gentoo.org>:
  Add the --eval option which makes keychain startup easier.  See the man-page
  for examples.  Get rid of the release notes from README, so now this file is
  where changes are tracked.

* keychain 2.5.5 (28 Jul 2005)

  28 Jul 2005; Aron Griffis <agriffis@gentoo.org>:
  Add the --env option and automatic reading of .keychain/env.  This allows
  variables such as PATH to be overridden for peculiar environments

* keychain 2.5.4.1 (11 May 2005)

  11 May 2005; Aron Griffis <agriffis@gentoo.org>:
  A minor bug in 2.5.4 resulted in always exiting with non-zero status.  Change
  back to the correct behavior of zero for success, non-zero for failure

* keychain 2.5.4 (11 May 2005)

  11 May 2005; Aron Griffis <agriffis@gentoo.org>:
  Fix bug 92316: If any locale variables are set, override them with LC_ALL=C.
  This fixes a multibyte issue with awk that could keep a running ssh-agent from
  being found.
  Fix bug 87340: Use files instead of symlinks for locking, since symlink
  creation is not atomic on cygwin.

* keychain 2.5.3.1 (10 Mar 2005)

  10 Mar 2005; Aron Griffis <agriffis@gentoo.org>:
  Fix problem introduced in 2.5.3 wrt adding gpg keys to the agent.  Thanks
  to Azarah for spotting it.

* keychain 2.5.3 (09 Mar 2005)

  09 Mar 2005; Aron Griffis <agriffis@gentoo.org>:
  Improve handling of DISPLAY by unsetting if blank.  Call gpg with
  --use-agent explicitly.

* keychain 2.5.2 (06 Mar 2005)

  06 Mar 2005; Aron Griffis <agriffis@gentoo.org>:
  Fix bug 78974 "keychain errors on Big/IP (x86 BSD variant)" by refraining
  from using ! in conditional expressions.  Fix RSA fingerprint extraction
  on Solaris, reported in email by Travis Fitch.  Use $HOSTNAME when
  possible instead of calling uname -n to improve bash_profile
  compatibility.

* keychain 2.5.1 (12 Jan 2005)

  12 Jan 2005; Aron Griffis <agriffis@gentoo.org>:
  Don't accidentally inherit a forwarded agent when
  inheritwhich=local-once.  Move the --stop warning after the version
  splash.

* keychain 2.5.0 (07 Jan 2005)

  07 Jan 2005; Aron Griffis <agriffis@gentoo.org>:
  Add inheritance support via --inherit.  Add parameters to --stop for
  more control.  Change the default behavior of keychain to inherit if
  there's no keychain agent running ("--inherit local-once"), and
  refrain from killing other agents unless "--stop others" is
  specified.

* keychain 2.4.3 (17 Nov 2004)

  17 Nov 2004; Aron Griffis <agriffis@gentoo.org>:
  Fix bug 69879: Update findpids to work again on BSD; it has been
  broken since the changes in version 2.4.2.  Now we use OSTYPE (bash)
  or uname to determine the system type and call ps appropriately.

* keychain 2.4.2.1 (30 Sep 2004)

  30 Sep 2004; Aron Griffis <agriffis@gentoo.org>:
  Fix minor issues in the test for existing gpg keys wrt DISPLAY

* keychain 2.4.2 (29 Sep 2004)

  29 Sep 2004; Aron Griffis <agriffis@gentoo.org>:
  Make gpg support more complete.  Allow adding keys, clearing the
  agent, etc.  Fix --quick support to work properly again; it was
  broken since 2.4.0.  Change default --attempts to 1 since the progs
  ask multiple times anyway.

* keychain 2.4.1 (22 Sep 2004)

  22 Sep 2004; Aron Griffis <agriffis@gentoo.org>:
  Fix bugs 64174 and 64178; support Sun SSH, which is really OpenSSH
  in disguise and a few critical outputs changed.  Thanks to Nathan
  Bardsley for lots of help debugging on Solaris 9

  15 Sep 2004; Aron Griffis <agriffis@gentoo.org>:
  Fix pod2man output so it formats properly on SGI systems.  Thanks to
  Matthew Moore for reporting the problem.

* keychain 2.4.0 (09 Sep 2004)

  09 Sep 2004; Aron Griffis <agriffis@gentoo.org>:
  Fix bug 26970 with first pass at gpg-agent support

  Fix Debian bug 269722; don't filter output of ssh-add

  Fix bug reported by Marko Myllynen regarding keychain and Solaris
  awk's inability to process -F'[ :]'

  Fix bug in now_seconds calculation, noticed by me.

* keychain 2.3.5 (28 Jul 2004)

  28 Jul 2004; Aron Griffis <agriffis@gentoo.org>:
  Fix bug 58623 with patch from Daniel Westermann-Clark; don't put an
  extra newline in the output of listmissing

  Generate keychain.spec from keychain.spec.in automatically so that
  the version can be set appropriately.

* keychain 2.3.4 (24 Jul 2004)

  24 Jul 2004; Aron Griffis <agriffis@gentoo.org>:
  Fix bug 28599 reported by Bruno Pelaia; ignore defunct processes in
  ps output

* keychain 2.3.3 (30 Jun 2004)

  30 Jun 2004; Aron Griffis <agriffis@gentoo.org>:
  Fix bug reported by Matthew S. Moore in email; escape the backticks
  in --help output

  Fix bug reported by Herbie Ong in email; set pidf, cshpidf and lockf
  variables after parsing command-line to honor --dir setting

  Fix bug reported by Stephan Stahl in email; make spaces in filenames
  work throughout keychain, even in pure Bourne shell

  Fix operation on HP-UX with older OpenSSH by interpreting output of
  ssh-add as well as the error status

* keychain 2.3.2 (16 Jun 2004)

  16 Jun 2004; Aron Griffis <agriffis@gentoo.org>:
  Fix bug 53837 (keychain needs ssh-askpass) by unsetting SSH_ASKPASS
  when --nogui is specified

* keychain 2.3.1 (03 Jun 2004)

  03 Jun 2004; Aron Griffis <agriffis@gentoo.org>:
  Fix bug 52874: problems when the user is running csh

* keychain 2.3.0 (14 May 2004)

  14 May 2004; Aron Griffis <agriffis@gentoo.org>:
  Rewrite the locking code to avoid procmail

* keychain 2.2.2 (03 May 2004)

  03 May 2004; Aron Griffis <agriffis@gentoo.org>:
  Call loadagent prior to generating HOSTNAME-csh file so that
  variables are set.

* keychain 2.2.1 (27 Apr 2004)

  27 Apr 2004; Aron Griffis <agriffis@gentoo.org>:
  Find running ssh-agent processes by searching for /[s]sh-agen/
  instead of /[s]sh-agent/ for the sake of Solaris, which cuts off ps
  -u output at 8 characters.  Thanks to Clay England for reporting the
  problem and testing the fix.

* keychain 2.2.0 (21 Apr 2004)

  21 Apr 2004; Aron Griffis <agriffis@gentoo.org>:
  Rewrote most of the code, organized into functions, fixed speed
  issues involving ps, fixed compatibility issues for various UNIXes,
  hopefully didn't introduce too many bugs.  This version has a
  --quick option (for me) and a --timeout option (for carpaski).

  Also added a Makefile and converted the man-page to pod for easier
  editing.  See perlpod(1) for information on the format.  Note that
  the pod is sucked into keychain and colorized when you run make.

* keychain 2.0.3 (06 Apr 2003)

  06 Apr 2003; Seth Chandler <sethbc@gentoo.org>:
  Added keychain man page, fixed bugs with displaying colors for keychain 
  --help.  Also added a $grepopts to fix the grepping for a pid on cygwin
  Also added a TODO document
  color fix based on submission by Luke Holden <email@alterself.org>

* keychain 2.0.2 (26 Aug 2002)

  26 Aug 2002; the Tru64 fix didn't work; it was being caused by "trap - foo"
  rather than "tail +2 -". Now really fixed.

  26 Aug 2002; fixed "ssh-add" call to only redirect stdin (thus enabling
  ssh-askpass) if ssh_askpass happens to be set; this is to work around a bug
  in openssh were redirecting stdin will enable ssh-askpass even if ssh_askpass
  isn't set, which contradicts the openssh 3.4_p1 man page. to enable
  ssh-askpass, keychain now requires that the ssh_askpass var be set to point
  to your askpass program.

* keychain 2.0.1 (24 Aug 2002)

  24 Aug 2002; "--help" fixes; the keychain files were listed as sh-${HOSTNAME}
  rather than ${HOSTNAME}-sh. Now consistent with the actual program. Thanks to
  Christian Plessl <plessl@tik.ee.ethz.ch>, others for reporting this issue.

  24 Aug 2002; cycloon <cycloon@linux-de.org>: "If you add < /dev/null when
  adding the missingkeys via "ssh-add ${missingkeys}" (at line 454 of version
  2.0) so that it reads: "ssh-add ${missingkeys} < /dev/null" then users can
  use program like x11-ssh-askpass in xfree to type in their passphrase. It
  then still works for users on shell, depending if $DISPLAY is set." Added. 
  
  24 Aug 2002; A fix to calling "tail" that *should* fix things for Tru64 Unix;
  unfortunately, I have no way to test but the solution should be portable to
  all other flavors of systems. Thanks to Mark Scarborough
  <Mark.Scarborough@broadwing.com> for reporting the issue.
  
  24 Aug 2002; Changed around the psopts detection stuff so that "-x -u $me f"
  is used; this is needed on MacOS X. Thanks to Brian Bergstrand
  <brian@classicalguitar.net>, others for reporting this issue.

* keychain 2.0 (17 Aug 2002)

  17 Aug 2002; (Many submitters): A fix for keychain when running on HP-UX
  10.20.
  
  17 Aug 2002; Patrice DUMAS - DOCT <dumas@centre-cired.fr>: Now perform help
  early on to avoid unnecessary processing. Also added --dir option to allow
  keychain to look in an alternate location for the .keychain directory (use
  like this: "keychain --dir /var/foo")
 
  17 Aug 2002; Martial MICHEL <martial@users.sourceforge.net>: Martial also
  suggested moving help processing to earlier in the script. He also submitted
  a patch to place .ssh-agent-* files in a ~/.keychain/ directory, which makes
  sense particularly for NFS users so I integrated the concept into the code.
 
  17 Aug 2002; Fred Carter <fred.carter@amberpoint.com>: Cygwin fix to use
  proper "ps" options.

  17 Aug 2002; Adrian Howard <adrianh@quietstars.com>: patch so that lockfile
  gets removed even if --noask is specified.

  17 Aug 2002; Mario Wolff <wolff@voll.prima.de>: Replaced an awk dependency
  with a shell construct for improved performance.

  17 Aug 2002; Marcus Stoegbauer <marcus@grmpf.org>, Dmitry Frolov
  <frolov@riss-telecom.ru>: I (Daniel Robbins) solved problems reported by
  Marcus and Dmitry (mis-parsed command line issues) by following Dmitry's good
  suggestion of performing argument parsing all at once at the top of the
  script.

  17 Aug 2002; Brian W. Curry <truth@bcurry.cjb.net>: Added commercial SSH2
  client support; improved output readability by initializing myfail=0;
  integrated Cygwin support into the main keychain script; improved Cygwin
  support by setting "trap" appropriately. Thanks Brian!

* keychain 1.9 (04 Mar 2002)

  04 Mar 2002; changed license from "GPL, v2 or later" to "GPL v2".
  
  04 Mar 2002; added "keychain.cygwin" for Cygwin systems.  It may be time to
  follow this pattern and start building separate, optimized scripts for each
  platform so they don't get too sluggish.  Maybe I could use a C preprocessor
  for this.
  
  06 Dec 2001; several people: Solaris doesn't like '-e' comparisons; switched
  to '-f'

* keychain 1.8 (29 Nov 2001)

  29 Nov 2001; Philip Hallstrom (philip@adhesivemedia.com) Added a "--local"
  option for removing the ${HOSTNAME} from the various files that keychain
  creates.  Handy for non-NFS users.
  
  29 Nov 2001; Aron Griffis (agriffis@gentoo.org) Using the Bourne shell "type"
  builtin rather than using the external "which" command.  Should make things a
  lot more robust and slightly faster.
  
  09 Nov 2001; Mike Briseno (mike@radik.com) Solaris' "which" command outputs
  "no lockfile in..." to stdout rather than stderr.  A one-line fix (test the
  error condition) has been applied.

  09 Nov 2001; lockfile settings tweak

  09 Nov 2001; Rewrote how keychain detects failed passphrase attempts.  If you
  stop making progress providing valid passphrases, it's three strikes and
  you're out.

  09 Nov 2001; Constantine P. Sapuntzakis (csapuntz@stanford.edu) Some private
  keys can't be "ssh-keygen -l -f"'d; this patch causes keychain to look for
  the corresponding public key if the private key doesn't work.  Thanks
  Constantine!

  09 Nov 2001; Victor Leitman (vleitman@yahoo.com) CYAN color misdefined;
  fixed.
  
  27 Oct 2001; Brian Wellington (bwelling@xbill.org) A "quiet mode" (--quiet)
  fix; I missed an "echo".
  
  27 Oct 2001; J.A. Neitzel (jan@belvento.org) Missed another "kill -9"; it's
  now gone.

* keychain 1.7 (21 Oct 2001) 
 
  21 Oct 2001; Frederic Gobry (frederic.gobry@smartdata.ch) Frederic suggested
  using procmail's lockfile to serialize the execution of critical parts of
  keychain, thus avoiding multiple ssh-agent processes being started if you
  happen to have multiple xterms open automatically when you log in.
  Initially, I didn't think I could add this, since systems may not have the
  lockfile command; however, keychain will now auto-detect whether lockfile is
  installed; if it is, keychain will automatically use it, thus preventing
  multiple ssh-agent processes from being spawned. 
  
  21 Oct 2001; Raymond Wu (ursus@usa.net): --nocolor test is no longer inside
  the test for whether "echo -e" works.  According to Raymond, this works
  optimally on his Solaris box.
  
  21 Oct 2001; J.A. Neitzel (jan@belvento.org): No longer "kill -9" our
  ssh-agent processes. SIGTERM should be sufficient and will allow ssh-agent to
  clean up after itself (this reverses a previously-applied patch).
  
  21 Oct 2001; Thomas Finneid (tfinneid@online.no): Added argument "--quiet |
  -q" to make the program less intrusive to the user; with it, only error and
  interactive messages will appear.
  
  21 Oct 2001; Thomas Finneid (tfinneid@online.no): Changed the format of some
  arguments to bring them more in line with common *nix programs: added "-h" as
  alias for "--help"; added "-k" as alias for "--stop"

  21 Oct 2001; Mark Stosberg (mark@summersault.com): $pidf to "$pidf" fixes to
  allow keychain to work with paths that include spaces (for Darwin and MacOS X
  in particular).
  
  21 Oct 2001; Jonathan Wakely (redi@redi.uklinux.net): Small patch to convert
  "echo -n -e" to "echo -e "\c"" for FreeBSD compatibility.

* keychain 1.6 (15 Oct 2001)

  13 Oct 2001; Ralf Horstmann (ralf.horstmann@webwasher.com): Add /usr/ucb to
  path for Solaris systems.
  
  11 Oct 2001; Idea from Joe Reid (jreid@vnet.net): Try to add multiple keys
  using ssh-add; avoid typing in identical passphrases more than once.  Good
  idea!

*keychain 1.5 (21 Sep 2001)

  21 Sep 2001; David Hull (hull@paracel.com): misc. compatibility, signal
  handling, cleanup fixes
  
  21 Sep 2001; "ps" test to find the right one for your OS.

  20 Sep 2001; Marko Myllynen (myllynen@lut.fi): "grep [s]sh-agent" to "grep
  [s]sh-agent" (zsh fix)

*keychain 1.4 (20 Sep 2001)

  20 Sep 2001; David Hull (hull@paracel.com): "touch $foo" to ">$foo"
  optimization and other "don't fork" fixes.  Converted ${foo#--} to a case
  statement for Solaris sh compatibility.

  20 Sep 2001; Try an alternate "ps" syntax if our default one fails.  This
  should give us Solaris and IRIX (sysV) compatibility without breaking BSD.

  20 Sep 2001; Hans Peter Verne (h.p.verne@usit.uio.no); "echo -e" to "echo $E"
  (for IRIX compatibility with --nocolor), optimization of grep ("grep
  [s]sh-agent")
  
  17 Sep 2001; Marko Myllynen (myllynen@lut.fi): Various fixes: trap signal 2
  if signal INT not supported (NetBSD); handle invalid keys correctly; ancient
  version of ash didn't support ~, so using $HOME; correct zsh instruction;
  minor cleanups

*keychain 1.3 (12 Sep 2001)
  
  12 Sep 2001; Minor color changes; the cyan was hard to read on xterm-colored
  terms so it was switched to bold.  Additional --help text added.
  
  10 Sep 2001; We now use .ssh-agent-[hostname] instead of .ssh-agent.  We now
  create a .ssh-agent-csh-[hostname] file that can be sourced by csh-compatible
  shells.  We also now kill all our existing ssh-agent processes before
  starting a new one.

  10 Sep 2001; Robert R. Wal (rrw@hell.pl): Very nice NFS fixes, colorization
  fixes, tcsh redirect -> grep -v fix.  Thanks go out to others who sent me
  similar patches.

  10 Sep 2001; Johann Visagie (johann@egenetics.com): "source" to "."
  shell-compatibility fixes.  Thanks for the FreeBSD port.

  10 Sep 2001; Marko Myllynen (myllynen@lut.fi): rm -f $pidf after stopping
  ssh-agent fix

*keychain 1.2 

  09 Sep 2001; README updates to reflect new changes.
  
  09 Sep 2001; Marko Myllynen (myllynen@lut.fi): bash 1/zsh/sh compatibility;
  now only tries to kill *your* ssh-agent processes, version fix, .ssh-agent
  file creation error detection.  Thanks! 

*keychain 1.1; fixes for calling "pidof"; README; ChangeLog

  07 Sep 2001; Addition of README stating that keychain requires bash 2.0 or
  greater, as well as quick install directions and web URL.

  07 Sep 2001; Explicitly added /sbin and /usr/sbin to path, and then called
  "pidof".  I think that this is a bit more robust.
  
  06 Sep 2001; from John Ellson (ellson@lucent.com): "pidof" changed to
  "/sbin/pidof", since it's probably not in $PATH
 
  06 Sep 2001; New ChangeLog! :)

*keychain 1.0; initial release (Aug 2001)
