$(basename $0) [-t timeout] [-i interval] [-d delay] distdir
Launch Spyder.app located in distdir with a time-out.
Upon time-out expiration SIGTERM (15) is sent to Spyder. If SIGTERM
signal is blocked, then the subsequent SIGKILL (9) terminates it.

  distdir     Directory in which Spyder.app resides.

  -t timeout  Number of seconds to wait for command completion.
              Default value: $timeout seconds.

  -i interval Interval between checks if the process is still alive.
              Positive integer, default value: $interval seconds.

  -d delay    Delay between posting the SIGTERM signal and destroying the
              process by SIGKILL. Default value: $delay seconds.

Bash does not support floating point arithmetic (sleep does),
therefore all delay/time values must be integers.
