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 [E. Remiddi, J.A.M. Vermaseren, Int. J. Modern Phys. A 15 (2000) 725, hep-ph/9905237] and have many applications in high energy particle physics. Title of program: HPL Catalogue Id: ADWX_v2_0 Nature of problem Computer algebraic treatment of the harmonic polylogarithms which appear in the evaluation of Feynman diagrams.
