20:15 CoCoA-5 Feature #708: ExternalLib Normaliz: verbose flag?

Normaliz has only two levels of verbosity: off or on. Via libnormaliz this can be toggled. I think the CoCoA interfac...

15:03 CoCoALib Feature #253: W.Bruns's wish list

An issue I stumbled on recently is 3) from my wish list. I think it is not yet implemented. Suppose I produce a polyn...

14:54 CoCoALib Bug #228: libcocoa sometimes built without its index

I have completely forgotten what the problem was. I don't think it is relevant anymore.

14:49 CoCoA-5 Feature #711: External Libs: print credits?

The Normaliz header of the development version that will soon become 3.3.0 now lists the external packages compiled i...

10:43 CoCoALib Feature #342: Remove denominators: QQ[x] -> ZZ[x] (and PushBack(coeff, PP))
