+# 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.
