Nature of problem: The code of Monte Carlo generators often has to be tuned to the needs of large HEP Collaborations and experiments. Usually, these modifications do not introduce important changes in the algorithm, but rather modify the initialization and form of the hadronic current in τ decays. The format of the event record (HEPEVT common block) used to exchange information between building blocks of Monte Carlo systems often needs modification. Thus, there is a need to maintain various, slightly modified versions of the same code. The package presented here allows the production of ready-to-compile versions of TAUOLA [1,2] and PHOTOS [3] Monte Carlo generators with appropriate demonstration programs. The new algorithm, universal interface of TAUOLA to work with the HEPEVT common block, is also documented here. Finally, minor technical improvements of TAUOLA and PHOTOS are also listed.
Solution method: The standard UNIX tool: the C-language preprocessor is used to produce a ready-to-distribute version of TAUOLA and PHOTOS code. The final FORTRAN code is produced from the library of 'pre-code' that is included in the package.
Additional comments: This older version does not include features described in Section 9 of the paper; the updated version is already available from the CPC Program Library. PHOTOS and TAUOLA were first submitted to the library as separate programs. Summary details of these previous programs are shown in the Other versions section above. Note also that future versions may become available from the web page, http://cern.ch/wasm/goodies.html
Running time: Depends on the speed of the computer used and the demonstration program chosen. Typically a few seconds.
