En ayant jeté un oeil rapidement je dirais que ça fait rien de plus que
le module de Konrad de scientific python

Sinon ce que fait llgeometry necessite de manipuler des polynomes à
plusieurs variables ce que ni l'un ni l'autre ne font.

enfin, presque car le module de Konrad permet de définir et d'évaluer
des polynômes à plusieurs variables.
