  The shell-type supernova remnant RX J1713.7--3946 was observed during three
years with the H.E.S.S. Cherenkov telescope system. The first observation
campaign in 2003 yielded the first-ever resolved TeV gamma-ray image. Follow-up
observations in 2004 and 2005 revealed the very-high-energy gamma-ray
morphology with unprecedented precision and enabled spatially resolved spectral
studies. Combining the data of three years, we obtain significantly increased
statistics and energy coverage of the gamma-ray spectrum as compared to earlier
H.E.S.S. results. We present the analysis of the data of different years
separately for comparison and demonstrate that the telescope system operates
stably over the course of three years. When combining the data sets, a
gamma-ray image is obtained with a superb angular resolution of 0.06 degrees.
The combined spectrum extends over three orders of magnitude, with significant
gamma-ray emission approaching 100 TeV. For realistic scenarios of
very-high-energy gamma-ray production, the measured gamma-ray energies imply
efficient particle acceleration of primary particles, electrons or protons, to
energies exceeding 100 TeV in the shell of RX J1713.7--3946.
