TAUOLA as tau Monte Carlo for future applications

The status of the Monte Carlo programs for the simulation of the τ lepton production and decay in high energy accelerator experiments is reviewed. In particular, the status of the following packages is discussed: (i) TAUOLA for τ-lepton decay, (ii) PHOTOS for radiative corrections in decays, (iii) MC-TESTER packages for various types of semi-automatic tests and (iv) universal interface of TAUOLA for the decay of τ-leptons produced by “any” generator. Emphasis is put on recent developments for high precision tests and extensions of PHOTOS. Some considerations for the software organisation necessary in future applications for Belle and BaBar will be given, examples of the TAUOLA universal interface use, will only be listed at the end of the review.
