Any shell resource agent should source the .ocf-shellfuncs function library. With the syntax below, this is done in terms of $OCF_FUNCTIONS_DIR, which — for testing purposes, and also for generating documentation — may be overridden from the command line.

# Initialization:
: ${OCF_FUNCTIONS_DIR=${OCF_ROOT}/lib/heartbeat}
. ${OCF_FUNCTIONS_DIR}/ocf-shellfuncs
