SAPHanaTopology - DIR_PROFILE usage ?

function header claims DIR_PROFILE is set .. what is the purpose, as this variable is not used in this RA?

# function: sht_init - initialize variables for the resource agent
# globals:  DIR_EXECUTABLE(w), SAPSTARTSRV(w), SAPCONTROL(w), DIR_PROFILE(w), SAPSTARTPROFILE(w), LD_LIBRARY_PATH(w), PATH(w), nodelist(w)
