CTAN update: xintsession
Add &ROOTS interface to under-the-hood usage of the polexpr facilities allowing to get all real roots of the given polynomial to arbitrary precision (and all rational roots exactly). Dubbed "alpha" simply because I hesitate about the names &ROOTS and &REFINEROOTS, and whether to have a variant which does not automatically look exactly for the rational roots, or a variant to refine only one given root. Also because I added the interface rather quickly (all of the hard work having been already done at the polexpr level).

xintsession – Interactive computing sessions (fractions, floating points, polynomials)
Once xintsession is loaded, ε-TeX becomes an interactive computing software capable of executing arbitrary precision calculations, or exact calculations with arbitrarily big fractions. It can also manipulate polynomials as algebraic entities.
Numerical variables and functions can be defined during the session, and each evaluation result is stored in automatically labeled variables. A file is automatically created storing inputs and outputs.
