# For easily starting and stopping the jetty server (that is included with 
# the solr extension for Greenstone 3) from the command-line.
# First source gs3-setup.sh, then this script can be run as follows:
#     run_solr_server.pl start
# which runs the jetty server. 
# To stop the jetty server, re-run the script with the stop parameter:
#     run_solr_server.pl stop
