# command is executed. Specifies whether JVM should suspend
# execution immediately after startup. Default is "n".
#
# JPDA_OPTS (Optional) Java runtime options used when the "jpda start"
# command is executed. If used, JPDA_TRANSPORT, JPDA_ADDRESS,
# and JPDA_SUSPEND are ignored. Thus, all required jpda
# options MUST be specified. The default is:
#
# -agentlib:jdwp=transport=$JPDA_TRANSPORT,
# address=$JPDA_ADDRESS,server=y,suspend=$JPDA_SUSPEND
#
# JSSE_OPTS (Optional) Java runtime options used to control the TLS
# implementation when JSSE is used. Default is:
# "-Djdk.tls.ephemeralDHKeySize=2048"

# CATALINA_PID (Optional) Path of the file which should contains the pid
# of the catalina startup java process, when start (fork) is
# used
#
# LOGGING_CONFIG (Optional) Override Tomcat's logging config file

# Example (all one line)
# LOGGING_MANAGER="-Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager"
#
# USE_NOHUP (Optional) If set to the string true the start command will
# use nohup so that the Tomcat process will ignore any hangup
# signals. Default is "false" unless running on HP-UX in which
# case the default is "true"
