+     "Tempo analyzes pulsar timing data.  Pulse times of arrival (TOAs),
+pulsar model parameters, and coded instructions are read from one or more
+input files.  The TOAs are fitted by a pulse timing model incorporating
+transformation to the solar-system barycenter, pulsar rotation and spin-down
+and, where necessary, one of several binary models.  Program output includes
+parameter values and uncertainties, residual pulse arrival times, chi-squared
+statistics, and the covariance matrix of the model.  In prediction
+mode,ephemerides of pulse phase behavior (in the form of polynomial
+expansions) are calculated from input timing models.")
