Ok, I reduced the whole sage spkg package just to:
$ ls
all_cmdline.py all_notebook.py all.py categories ext __init__.py
__init__.pyc misc server structure version.py
and it still seems to build and the notebook works. I'll now strip it
even further. And later implement (1) and (2) as you suggested.
