V2.00/18-Aug-2007:
   * More clearly defined the return values of hatimerun.
   * added -E option to halockrun so that a distinction between
     locking problems and other errors is possible.

V1.12/14-Aug-2006:
   * Fixed a bug which caused a compile time error on systems which
     need -lposix4 to have nanosleep() available (Thx to Stefan 
     Berglund for reporting and analyzing).
   * Fixed some warnings with -pedantic

V1.11/19-Jun-2006:
   * Fixed a bug in hatimerun which caused environment manipulation
     on some platforms. 
     The problem was observed, analyzed and reported by Thomas
     Picherot.

V1.10/27-May-2006:

   * Introduced the possibility to specify multiple -t -k and -e
     options to hatimerun. This allows sending more then one signal
     if the process doesn't terminate after the first one.

V1.00/15-Mar-2005:

   * Fixed a race-condition in hatimerun which could cause zombies
     until the timeout appears. Thx to Michael Polivanov for the report.


V0.99.09/7-Jan-2003:

   * Added the test mode for halockrun. Using the -t flag halockrun
     can check a file for a lock, if the file is locked (e.g. by
     another halockrun) the PID of the process holding the lock
     will be printed to stdout.
   * minor portability improvements

V0.99.08/26-Oct-2001:

   * Changed halockrun to not fork. This can be changed via the "-f" option.
   * Made signalhandling for halockrun and hatimerun to ignore TERM,
     HUP, INT, PIPE, QUIT, USR1 and USR2 in the parent.
   * Changed exitcode of hatimerun and halockrun if the child
     abnormally aborts.
   * hatimerun will always wait fot the child to exit, even if the timeout
     occures.
   * Fixed bug which caused hatimerun to not recognize "-k HUP" on non
     BSD systems.
 
   
V0.99.07/9-Aug-2001:

   * Applied patch from Scott Gallaher to fix some warnings.
   * Fixed getopt behavior on GNU systems (POSIXLY_CORRECT)
   * Fixed returncode of getopt (works on AIX now)
   * Improved Signallist creation procedure (works now for AIX and Solaris)
