      to a WLIE experience (Work Like I Expect).  'exp_pid', 'match_max',
      'log_file', 'log_user', even 'send' (which is an alias for 'print')
      are all there now.  But I won't make 'send_user' an alias for
      'print STDOUT', you have to draw a line somewhere.
    + some diagnosis messages now use cluck to print a stacktrace
      (suggested by horos@earth.he.net)
    + there is a new option 'restart_timeout_upon_receive', that, when
      set to 1, will restart the timeout within the expect call.  This is
      useful when supervising an application that produces periodic, but
      not well-defined output and you still want to react to certain
      patterns.  Just say
    
        $exp->restart_timeout_upon_receive(1);
        $exp->expect($timeout,
                     [ timeout => \&report_timeout ],
                     [ qr/pattern/ => \&handle_pattern ]);

1.10 2000-11-22
    I cannot believe it: a syntax error in Expect.pm slipped through 
      (probably when I changed the version number after testing the patches),
      forcing me to do anouther release. >:-(

1.09 2000-11-21
    Various small bugfixes: exp_before didn't get set on timeout,
      the expect call didn't return on matching EOF, spawn didn't die when
      exec failed, Expect crashed in certain cases.

1.08 2000-09-20
    Added multi-match functionality (see docu)  --Roland

1.07 1998-07-12
    Changed the ver by .01 so I could get it up on CPAN :P

1.06
    Added exp_before(), exp_after(), exp_match(), exp_match_number(), exp_error().

1.05
    Added debug level '3'. Fixed/added to tutorial, fixed a couple of minor bugs.

1.04 1998-03-12
    Made all handles exp_inited autoflush. IO::Pty does the spawned 
      processes for us. All regexp patterns passed to expect() are now 
      multiline matched-- this makes matching ^ work for the beginning of lines.
      Unfortunately due to limitations in perl matching $ as the end of a line
      doesn't work if you are being returned \r\n instead of just \n. In this case
      you can use \r?$ to match the end of a line.
    exp_stty now checks to make sure the FH is a tty.

1.03
    Reworked expect() to make the code more fluid. Removed ~50 lines of
      cruft. Added soft_close() and hard_close() (see Expect.pod for details).

1.02
    Killed the $Expect::Use_Regexps stuff. Changed expect to look for '-re'
      strings indicating the subsequent pattern is to be matched as a regular
      expression.

1.01 1997-12-15
    Dropped process still alive during expect. Sometimes the process dies
      before the handle finishes getting read. Fixed a typo that caused a response
      of 'child process died' if a successfull pattern had a null value.
    Added the ability to do expect() literals instead of regular
      expressions. see $process->use_regexps and the package global 
      $Expect::Use_Regexps.
    Fixed internals to work with the documented fashion for using file
      ojects. everything is internally represented as ${*$process}{exp_variable} 
      instead of ${*$process}{variable}. Pids should be checked with 
      $process->pid() now, since $process->{Pid} no longer exists.
    exp_kill() is obsolete. Use kill($signal,$process->pid()).

1.00
    exp_close no longer sends an exp_kill() to the process. This was kind
      of a dumb thing to do in the first place. Processes should go away after they
      are close()d. In fact, there really isn't any point in using exp_close. Just
      use $process->close();. -This isn't true as of 1.03, where soft and hard close
      were added to help deal with buffering issues.

0.99
    Changed expect() to return the index of the matched pattern + 1. This
      enables the 'quick and dirty'   $process->expect($timeout,'patern') || die;
      sort of behavior.

0.98
    Changed everything. Now requires IO::Tty and uses IO::Stty. This
      should make it work on any posix-supporting platform that includes a method
      of obtaining a pty. Got rid of the 'detach' stuff, as it cluttered stuff up
      too much. Do your own forking.
    Default settings are now done by directly setting Expect::Values, such
      as $Expect::Debug and $Expect::Log_Stdout. Things now use 'spawn ids' and
      'handle ids' instead of handle numbers. This makes debugging a little more 
      sensible.
    Though there may be more bugs in the ver. I'm hopeful it should prove
      to be much more stable, reliable, intuitive and portable than previously.

0.972
    Fixed setpgrp to be setsid. Oops. Processes opening /dev/tty should be
      much happier now.

0.97
    Forced baud rate to get set at startup to make sure it wasn't set to 0
      and sending EOFs. Linux now hangs consistently. It will probably not work until
      I get to the stty module. Sigh. Time to stop being lazy :)
    Also forced complete handle flushing after handles are opened. Probably
      a bit anal but I'd rather err on the side of safety.
    After the stty problem gets fixed I'll probably change over eveything
      to use the IO::Pty module. 

0.96
    Fixed a couple of idiot mistakes concerning DEBUG mode and printing
      debug info to STDERR. Changed some debugging spots so debugging info will 
      always be printed in readable escaped format rather than raw input.

0.95
    Linux had this bizarre problem of stty occasionally not returning when
      setting raw -echo. My solution was to run it twice, once for raw and once for
      echo. The real solution is of course to write an stty function using the POSIX
      module.. any volunteers? :-)
