# Alternative configuration:

# Misc commentary.
# The sh -e option exits on failure, avoiding the need to guard commands.
# The sh -v option echos commands before executing them, avoiding the
# need to do so manually.
# I'm dubious about
# (a) invoking "make" here at all,
# (b) using make option -j instead of leaving that to the user, via ${MAKEFLAGS},
# (c) using make option -j instead of -jX where X = #CPUs.
# The "if" stanza addresses (c), and partially addresses (b) by avoiding overriding
# or augmenting ${MAKEFLAGS} if it is already set.
