This script is used to run the jmx proxy
By default it would connect to the local API ($API_ADDR) and will listen on the JMX port ($JMX_PORT)
This script receives the following command line arguments:
$PARAM_HELP - print this help screen and exit
$PARAM_JMX_PORT <port> - The jmx port to open
$PARAM_API_PORT <port> - The API port to connect to
$PARAM_ADDR <address> - The API address to connect to
$PARAM_JMX_ADDR <address> - JMX bind address
$PARAM_FILE <file> - A configuration file to use
$PARAM_LOCATION <location> - The location of the jmx proxy jar file
$ALLOW_REMOTE - When set allow remote jmx connectivity
$ALLOW_DEBUG - When set open debug ports for remote debugger
HLPEND
