# If printf is a shell builtin command, then we can
# implement cheaper versions of basename and dirname
# that do not involve any fork/exec overhead.
# If printf is not builtin, approximate it using echo,
# and hope there are no weird file names that cause
# some versions of echo to do the wrong thing.
# (Converting to this version of dirname speeded up the
# syspkgdeps script by an order of magnitude, from 68
# seconds to 6.3 seconds on one particular host.)
#
# Note that naive approximations for dirname
# using ${foo%/*} do not do the right thing in cases
# where the result should be "/" or ".".
