 # OPTIONS:
 #   -f: start in foreground
 #   -p <filename>: log the pid to a file (useful to kill it later)
 #   -v: print version string and exit

 # CONTROLLING STARTUP:
 #
 # This script relies on few environment variables to determine startup
 # behavior, those variables are:
 #
 #   CLASSPATH -- A Java classpath containing everything necessary to run.
 #   EXTRA_CLASSPATH -- A Java classpath with anything to be appended to CLASSPATH
 #   JVM_OPTS -- Additional arguments to the JVM for heap size, etc
 #   JVM_ON_OUT_OF_MEMORY_ERROR_OPT -- The OnOutOfMemoryError JVM option if specified
 #   CASSANDRA_CONF -- Directory containing Cassandra configuration files.
 #   CASSANDRA_LOG_DIR -- Directory containing logs(default: $CASSANDRA_HOME/logs).
 #
 # As a convenience, a fragment of shell is sourced in order to set one or
 # more of these variables. This so-called `include' can be placed in a
 # number of locations and will be searched for in order. The highest
 # priority search path is the same directory as the startup script, and
 # since this is the location of the sample in the project tree, it should
 # almost work Out Of The Box.
 #
 # Any serious use-case though will likely require customization of the
 # include. For production installations, it is recommended that you copy
 # the sample to one of /usr/share/cassandra/cassandra.in.sh,
 # /usr/local/share/cassandra/cassandra.in.sh, or
 # /opt/cassandra/cassandra.in.sh and make your modifications there.
 #
 # Another option is to specify the full path to the include file in the
 # environment. For example:
 #
 #   $ CASSANDRA_INCLUDE=/path/to/in.sh cassandra -p /var/run/cass.pid
 #
 # Note: This is particularly handy for running multiple instances on a
 # single installation, or for quick tests.
 #
 # Finally, developers and enthusiasts who frequently run from an SVN
 # checkout, and do not want to locally modify bin/cassandra.in.sh, can put
 # a customized include file at ~/.cassandra.in.sh.
 #
 # If you would rather configure startup entirely from the environment, you
 # can disable the include by exporting an empty CASSANDRA_INCLUDE, or by
 # ensuring that no include files exist in the aforementioned search list.
 # Be aware that you will be entirely responsible for populating the needed
 # environment variables.

 # NB: Developers should be aware that this script should remain compatible with
 # POSIX sh and Solaris sh. This means, in particular, no $(( )) and no $( ).

 # If an include wasn't specified in the environment, then search for one...
