+   satisified or not, but delay the actual determination until the
+   prerequisite is actually used by "test_have_prereq" or the
+   three-arg form of the test_expect_* functions.  For example, this

+   supports symbolic links:
+
+	test_lazy_prereq SYMLINKS '
+		ln -s x y && test -h y
+	'
+
+   The script is lazily invoked when SYMLINKS prerequisite is first
+   queried by either "test_have_prereq SYMLINKS" or "test_expect_*
+   SYMLINKS ...".  The script is run in a temporary directory inside
+   a subshell, so you do not have to worry about removing temporary
+   files you create there.  When the script exits with status 0, the
+   prerequisite is set.  Exiting with non-zero status other than 125
+   makes the prerequisite unsatisified.  Exiting the script with 125
+   signals a programming error and is used to mark a prerequisite that
+   should not be used by test scripts.
