  Measurements of tau lepton, because of its long lifetime, large mass and
parity sensitive couplings lead to broad physics interest. From the perspective
of high-energy experiments such as at LHC, knowledge of tau lepton properties
offers an important ingredient of new physics signatures. From the perspective
of lower energies, tau lepton decays constitute an excellent laboratory for
hadronic interactions. At present,hundreds of millions of tau decays have been
amassed by both Belle and BaBar experiments. It is of utmost importance to
represent such data in a form as useful for general applications as possible.
In the present paper we describe the set of form factors for hadronic tau
decays based on Resonance Chiral Theory. The technical implementation of the
form factors in FORTRAN code is also explained. It is shown how it can be
installed into TAUOLA Monte Carlo program. Then it is rather easy to implement
into software environments of not only Belle and BaBar collaborations but also
for FORTRAN and C++ applications of LHC. Description of the current for each
tau decay mode is complemented with technical numerical tests. The set is ready
for fits, parameters to be used in fits are explained. Arrangements to work
with the experimental data not requiring unfolding are prepared. Hadronic
currents, ready for confrontation with the tau decay data, but not yet ready
for the general use, cover more than 88% of hadronic tau decay width.
