Subject: sci-mathematics/flintqs: new package for quadratic sieve factoring.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A straightforward import of the ebuild that François Bissey has
been maintaining in the sage-on-gentoo overlay. I added a test
suite that factors a large composite number based on the doctests
for qsieve() in SageMath.

Closes: https://bugs.gentoo.org/715090
Package-Manager: Portage-2.3.89, Repoman-2.3.20
