60# If printf is a shell builtin command, then we can
61# implement cheaper versions of basename and dirname
62# that do not involve any fork/exec overhead.
63# If printf is not builtin, approximate it using echo,
64# and hope there are no weird file names that cause
65# some versions of echo to do the wrong thing.
66# (Converting to this version of dirname speeded up the
67# syspkgdeps script by an order of magnitude, from 68
68# seconds to 6.3 seconds on one particular host.)

70# Note that naive approximations for dirname
71# using ${foo%/*} do not do the right thing in cases
72# where the result should be "/" or ".".
