# The whole contents of this file is run by dot-sourcing it from
# inside a shell function. It used to be that "return"s we see
# below were not inside any function, and expected to return
# to the function that dot-sourced us.
#
# However, older (9.x) versions of FreeBSD /bin/sh misbehave on such a
# construct and continue to run the statements that follow such a "return".
# As a work-around, we introduce an extra layer of a function
# here, and immediately call it after defining it.
