MPSolve stands for Multiprecision Polynomial SOLVEr. It is a software that aims to provide an easy to use (hopefully) universal blackbox for solving polynomials and secular equations.

Amongs its features you can find:
* Arbitrary precision approximation
* Guaranteed inclusion radii for the results
* Exploiting of polynomial structures: it can take advantage of sparsity as well as coefficients in a particular domain (i.e. integers or rationals).

Nightly builds (untested and potentially not-working) are also available at https://launchpad.net/~leo.robol/+archive/mpsolve-daily.
