startup, so I've supplied a sample init.sage file which will load this
code from ~/src/sage/.
+Newer versions of Sage don't load ~/.sage/init.sage during test mode,
+so the imports in mjo/all.py will fail by default. However, as long as
+the other modules don't rely on all.py, their tests should be fine.
