+#
+#    - foo.c defines the main testing function, main_test().
+#    - foo-lib.c implements the library functions that foo.c is testing.
+#
+# The functions in foo-lib.c will often want to abort on certain inputs.
+# They can use the global variable inside_main to see whether they are
+# being called from the test program or part of the common runtime.
+#
+# In many cases, the library functions will behave as normal at -O0
+# and abort when optimisation is enabled.  Such implementations should
+# go into the lib/ directory so that they can be included by any test
+# that needs them.  They shouldn't call any external functions in case
+# those functions were overridden too.
