That looks quite cool. spkg's are generally for non-Python files. The way to put a Python file into sage is to convert your .sage file to a .py file (for example, changing "^" to "**" throughout) and then putting it somewhere with the sage library files (for example, in $SAGE_ROOT/devel/sage-main/sage/schemes/generic/) Then you could, from the command line do from sage.schemes.generic.hodge_numbers_ci import * and have access to all of your functionality. Once you do so, get an account on sage_trac (e-mail William), post this as a ticket to include in Sage, get someone to review it and you're all set.
At some point we need to get around to improving the documentation for people in exactly your situation: just starting to contribute to the sage library. It was a project started at Sage Days 6, but hasn't gone very far since then. I like making a CompleteIntersection class eventually. David On Jan 14, 2008 8:38 AM, D.
