+    (description
+     "Subject recruitment for medical research is challenging.  Slow patient
+accrual leads to delay in research.  Accrual monitoring during the process of
+recruitment is critical.  Researchers need reliable tools to manage the
+accrual rate.  This package provides an implementation of a Bayesian method
+that integrates researcher's experience on previous trials and data from the
+current study, providing reliable prediction on accrual rate for clinical
+studies.  It provides functions for Bayesian accrual prediction which can be
+easily used by statisticians and clinical researchers.")
