A Pari/GP package for computing L-functions.

Based on an idea of Pascal Molin, we describe a GP script for computing with L-functions of any reasonable degree. Most of the talk will be computer demonstrations of examples. The audience can bring their own favourite L-functions, as long as they are easy to implement and most importantly that their conductor be not too large. This will enable me to add to the examples that I will present, and/or find bugs.
