# Shell function library to start and stop remctld
#
# Note that while many of the functions in this library could benefit from
# using "local" to avoid possibly hammering global variables, Solaris /bin/sh
# doesn't support local and this library aspires to be portable to Solaris
# Bourne shell.  Instead, all private variables are prefixed with "tap_".
