Describe LfunctionsAndModularFormsVIII here.
From William Stein:
I spent 2 solid weeks this summer writing L-functions "client code", which is here (it's in psage):
Most of the example usage is near the bottom. The two unusual features to this code are that (1) you specify the local factors of the L-series instead of the Dirichlet series coefficients, and (2) for *any* of the defining data of an L-function, one can replace it by a finite list of possibilities, and all will be tried until one that satisfies the functional equation is found.
My plan is that these new LSeries objects will be computable using both Dokchitser and lcalc. So far they only use Dokchitser's GP program, but I their usage of Dokchitser is pretty well abstracted away, and I intend to have them be able to easily use lcalc instead.
