# BOINC - start and stop the BOINC client daemon on Unix
#
#  Unix start/stop script to run the BOINC client as a daemon at
#  system startup, as the 'boinc' user (not root!).
#
#  This version works on Red Hat Linux, Fedora Core, Mandriva,
#  and Slackware Linux, and should work on generic Linux systems
#  provided they have 'pidof'.   Metadata for chkconfig and the SUSE
#  equivalent INIT info are included below.
#
#  Usage:  boinc { start | stop | restart | status }
#
