+    "PARI/GP is a widely used computer algebra system designed for fast
+computations in number theory (factorisations, algebraic number theory,
+elliptic curves...), but it also contains a large number of other useful
+functions to compute with mathematical entities such as matrices,
+polynomials, power series, algebraic numbers, etc., and a lot of
+transcendental functions.
+PARI is also available as a C library to allow for faster computations.")
