+# the reference is normally the interpreter (built with -DZYINTERP) and the second

+# runs with a timeout (JIT_TEST_TIMEOUT seconds, 120 by default). a program that
+# differs is listed with the first lines of the difference; the exit status of
+# this script is the number of programs that differ.
