# Wrapper
WRAPPER_CMD="/usr/bin/wrapper"
WRAPPER_CONF="/etc/freenet-wrapper.conf"

# Priority at which to run the wrapper.  See "man nice" for valid priorities.
#  nice is only used if a priority is specified.

# Note that Freenet will scale its usage within the specifed niceness, some
# threads will have a lower priority (higher nice value) than this. Also please
# don't renice Freenet once it's started.
PRIORITY=10

# Location of the pid file.

# If uncommented, causes the Wrapper to be shutdown using an anchor file.
#  When launched with the 'start' command, it will also ignore all INT and
#  TERM signals.

# If specified, the Wrapper will be run as the specified user.
# IMPORTANT - Make sure that the user has the required privileges to write
#  the PID file and wrapper.log files.  Failure to be able to write the log
#  file will cause the Wrapper to exit without any way to write out an error
#  message.
# NOTE - This will set the user which is used to run the Wrapper as well as
#  the JVM and is not useful in situations where a privileged resource or
#  port needs to be allocated prior to the user being changed.
