%description
Symbolic calculation and evaluation of multivariate polynomials with
rational coefficients. This package is strongly inspired by the 'spray'
package. It provides a function to compute Gröbner bases (reference
<doi:10.1007/978-3-319-16721-3>). It also includes some features for
symmetric polynomials, such as the Hall inner product. The header file of
the C++ code can be used by other packages. It provides the templated
class 'Qspray' that can be used to represent and to deal with multivariate
polynomials with another type of coefficients.
