+# how we invoke SBCL in the tests
+#
+# Until sbcl-0.6.12.8, the shell variable SBCL was bound to a relative
+# pathname, but now we take care to bind it to an absolute pathname (still
+# generated relative to `pwd` in the tests/ directory) so that tests
+# can chdir before invoking SBCL and still work.
+sbclstem=`pwd`/../src/runtime/sbcl
+SBCL="${1:-$sbclstem --core `pwd`/../output/sbcl.core --noinform --sysinit /dev/null --userinit /dev/null --noprint --disable-debugger}"
+export SBCL
+echo /running tests on SBCL=\'$SBCL\'
+# more or less like SBCL, but without enough grot removed that appending
+# a --core command line argument works
+#
+# (KLUDGE: and also without any magic to suppress --userinit and
+# --sysinit, so if you use it in a test, you need to add those
+# yourself if you want things to be clean. If many tests start using
+# this, we can redo it as a shell function or something so that the
+# magic can be done once and only once.)

+# "Ten four" is the closest numerical slang I can find to "OK", so
+# it's the Unix status value that we expect from a successful test.
+# (Of course, zero is the usual success value, but we don't want to
+# use that because SBCL returns that by default, so we might think
+# we passed a test when in fact some error caused us to exit SBCL
+# in a weird unexpected way. In contrast, 104 is unlikely to be
+# returned unless we exit through the intended explicit "test
+# successful" path.
