13:51 Slug #948: radical is slow (compared to singular) on these examples: I have found the (a?) slow step: there is a call to @saturate(I, ideal(RingElem(RingOf(G),G1)))@ taking a long time. Anna Maria Bigatti

16:17 Bug #963 (Feedback): Manual: XML problem with html doc: I cheated: instead of trying to understand XSL I just changed the few "<" into "&lt;".
