62# If printf is a shell builtin command, then we can
63# implement cheaper versions of basename and dirname
64# that do not involve any fork/exec overhead.
65# If printf is not builtin, approximate it using echo,
66# and hope there are no weird file names that cause
67# some versions of echo to do the wrong thing.
68# (Converting to this version of dirname speeded up the
69# syspkgdeps script by an order of magnitude, from 68
70# seconds to 6.3 seconds on one particular host.)
71#
72# Note that naive approximations for dirname
73# using ${foo%/*} do not do the right thing in cases
74# where the result should be "/" or ".".
