 Sage is a mathematical software package with support for a wide range
 of mathematics, including algebra, calculus, elementary to very
 advanced number theory, cryptography, numerical computation,
 commutative algebra, group theory, combinatorics, graph theory, and
 exact linear algebra.
 .
 Sage integrates several dozen mathematical software packages, making
 it possible to combine the best algorithms from several different
 packages together in a single Sage program.
 .
 Much of the Sage core and the Sage interfaces are implemented in
 Cython, helping Sage avoid the usual performance problems associated
 with Python.
 .
 Sage has a friendly command-line interface based on iPython and a
 web-based notebook interface which can run locally or connect to a
 remote Sage server over the network.
