#  Name:
#     voclientd
#
#  Purpose:
#
#  Description:
#     This shell script invokes the VOClient daemon.
#     It's not very complicated, but performs some argument manipulation
#     prior to invoking java with the right classpath and classname.
#
#     1. If a class path is specified using either the CLASSPATH
#        environment variable or the -classpath flag to this script,
#        it will be added to the application classpath.
#
#     2. Any initial command-line arguments which look like they are destined
#        for java itself (starting with -D or -X) will be sent to java,
#        and the others will be sent to the application.

#  Requisites:
#     - java should be on the path.
#
#     - the application jar file should exist in the same directory as this
#       command.
