My own personal library of Sage[1] code. It is intended to be loaded into every Sage session, or Python script which imports the Sage library. Sage loads ~/.sage/init.sage upon 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. [1] http://www.sagemath.org/
