# 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, Mandrake, Debian,
#  and Slackware Linux, and should work on generic Linux systems
#  provided that they have 'pidof' (most do).   
#  Metadata for chkconfig and the SUSE equivalent INIT info are included below.
#
#  Usage:  boinc { start | stop | status | restart }
#
