What is Pynac?
The main difference between Pynac and GiNaC is that Pynac relies on Sage to provide the operations on numerical types, while GiNaC depends on CLN for this purpose.
For more information on how Pynac came to be, and the differences between Pynac and GiNaC, please visit the FAQ page.

In order to use Pynac, one needs to have the Sage library available. Also see the FAQ entry about this.
We use the pynac-devel google group for discussions. You can also e-mail the developers directly at firstname.lastname@example.org and email@example.com with comments and suggestions.
