Extension of HPL to complex arguments

Abstract

In this paper we describe the extension of the Mathematica package HPL to treat harmonic polylogarithms of complex arguments. The harmonic polylogarithms have been introduced by Remiddi and Vermaseren and have many applications in high energy particle physics.
