+similar to that of the TxDb packages from the @code{GenomicFeatures} package,
+but, in addition to retrieve all gene/transcript models and annotations from
+the database, the @code{ensembldb} package also provides a filter framework
+allowing to retrieve annotations for specific entries like genes encoded on a
+chromosome region or transcript models of lincRNA genes.")
