I've been using Sage to do a bunch of calculations for a math paper I'm now finishing. I'm definitely citing Sage, as well as PARI/GP (which I used within Sage, as well as on its own before I started using Sage). But I'm wondering about how much else to cite. Using the "get_systems" command, I've found that different functions I've used make use of GAP, GiNaC, MPFR, MPFI, Maxima, GMP, FLINT, and Mpmath, and I'm not even done looking yet.
Does etiquette dictate that I cite (with both a mention in the text and a bibliography entry) each of those? On a gut level, that feels like a lot. And I don't know if any of those components are considered so basic that they're not worth mentioning. But I want to give credit where it's appropriate.
Thanks, John
