And or SAGE! As SAGE _is_ Python in a way, all Python programs run in SAGE.
So :g/Python/s//SAGE/g

Agreed Python/SAGE is far more readable compared to Mathematica (don't flame!).

As I wrote before about SAGE, we are in the proces of making available the OEIS
within SAGE. The database of sequences is already there, but in
sage-1.6 or sage-2.0 there will be a growing number of functions
to produce sequences:
A111776(n) will give the n-th number and
A111776_list(n) wil give the list of the first n numbers of ...

So in the long run we may see a line
%o A111776 (SAGE) sloane.A111776(n)

See http://www.research.att.com/~njas/sequences/A111776

As an alternative: place a link to an external location. This is certainly
more attractive for larger programs.
