I'm talking to Mike Hopkins about algebraic topology in Sage next week, and
I think this is one of the things he would like to see happen.  If anyone's
interested in thinking about good ways to incorporate it, let me know.  I
don't know much about the package yet, but I'll probably learn some next
week.
