+     "This package provides a system for querying, retrieving and analyzing
+protocol- and results-related information on clinical trials from three public
+registers, the European Union Clinical Trials Register (EUCTR),
+ClinicalTrials.gov (CTGOV) and the ISRCTN.  Trial information is downloaded,
+converted and stored in a database.  Functions are included to identify
+deduplicated records, to easily find and extract variables (fields) of
+interest even from complex nesting as used by the registers, and to update
+previous queries.  The package can be used for meta-analysis and
+trend-analysis of the design and conduct as well as for results of clinical
+trials.")
