jigsaw contrib: jigsaw.server startup script

Hi !

----

Here comes (as an attachment) the Solaris daemon script jigsaw.server
V1.4

This script allows that jigsaw runs as a system daemon (service), after
installation
of this script jigsaw is started and shut down at system startup and
shutdown.

Tested with Solaris 7 Sparc, but any Solaris >= 2.5.1 should work.

(It would be __really__ nice if someone tests if this script is
compatible with any
other Unix and make a report to me...)

----

Bye,
Roland

# version history
# V1.4 (03.05.1999): - added "save" option to save servers
#                    - "stop" option now waits until the "jigkill" background process returns
#                    - fixed delay in stop option (was "sleep 8" instead of "sleep 5"; bug introduced in V1.2)
#                    - fixed startup delay (should be 10 sec to see jigsaw's startup messages on console)
# V1.3 (28.04.1999): - changed CLASSPATH for new servlet archive /usr/local/java/jsdk2.1/servlet.jar
#                    - added SIGKILL shutdown method to force a "shutdown" of jigsaw service if SIGTERM did not work
#                    - added "restart_server" switch to make "stop" + "start" in one step.
#                      (I did not use the name "restart" because this may be reserved by another /etc/init.d/ script functionality...)
# V1.2             : - added "sleep 5" at startup to see servers startup messages before xdm/dtlogin hides this info...
# V1.1             : - initial release
