+# Stack limit calibration for `make check'.  (For why we do this, see
+# the comments in measure-hwm.scm.)  We're relying here on a couple of
+# bits of Automake magic.
+#
+# 1. The fact that "libguile" comes before "test-suite" in SUBDIRS in
+# our toplevel Makefile.am.  This ensures that the
+# stack-limit-calibration.scm "test" will be run before any of the
+# tests under test-suite.
+#
+# 2. The fact that each test is invoked as $TESTS_ENVIRONMENT $test.
+# This allows us to ensure that the test will be considered to have
+# passed, by using `true' as TESTS_ENVIRONMENT.
+#
+# Why don't we care about the test "actually passing"?  Because the
+# important thing about stack-limit-calibration.scm is just that it is
+# generated in the first place, so that other tests under test-suite
+# can use it.
