+ (description
+ "This package provides a system for querying, retrieving and analyzing
+protocol- and results-related information on clinical trials from three public
+registers, the @acronym{EUCTR, European Union Clinical Trials Register} @url{
+https://www.clinicaltrialsregister.eu/}, @acronym{CTGOV, ClinicalTrials.gov}
+@url{https://clinicaltrials.gov/} and the @acronym{ISRCTN, International Clinical
+Trials Registry Platform} @url{https://www.isrctn.com/}. 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.")
