%global desc \
PARI/GP is a computer algebra system designed for fast computations\
in number theory (factorizations, algebraic number theory, elliptic\
curves), but 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.\
