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