+     "This package provides functions for fitting continuous-time Markov and
+hidden Markov multi-state models to longitudinal data.  It was designed for
+processes observed at arbitrary times in continuous time (panel data) but some
+other observation schemes are supported.  Both Markov transition rates and the
+hidden Markov output process can be modelled in terms of covariates, which may
+be constant or piecewise-constant in time.")
