* open with a statement of what sage is for
* statement of nfs support on page 1
* example calculations sage can do:
 det of ...
 ell curves (padic lseries; sha)
 zeta functions for padic methods
 combine matlab, mathematica, maple, maxima, singular, gap, etc., together.
 multiply polys over ZZ
 graph isomorphism
 algebraic topology  mention Steenrod algebras
* why python/cython
* address why nzmath is the wrong approach:
e.g., very damning statements on page 8 about no peer review.
* something about mupadcombinat > sagecombinat
* something about algebraic topology
Main areas:
 number theory & arith geom
 algebraic combinatorics
 symbolic comp
 graph theory
 algebraic topology

emphasize broadness
* problems: referee system.
* platform for developing math software
