+ LSB headers.

20080315 - [dj] * Corrected test for $pidfile in pidofproc()
* Replaced exit with return in statusproc() - (lfs-functions)

+# Begin /lib/lsb/manage_functions
+
+# /lib/lsb/manage_functions contains the functions used by
+# /lib/lsb/install_initd and /lib/lsb/remove_initd as well as additional helper
+# functions for use in programs that would provide functionality similar to
+# the RedHat chkconfig utility, for instance.
+
+## Define rcbase for now
+## (this will go away when a config file is defined)

+# Define all arrays at script start to avoid scope issues
+# scriptlist is a list of valid scripts used as an index
