+    (description
+     "This package provides a high-level R interface to CoreArray @dfn{Genomic
+Data Structure} (GDS) data files, which are portable across platforms with
+hierarchical structure to store multiple scalable array-oriented data sets
+with metadata information.  It is suited for large-scale datasets, especially
+for data which are much larger than the available random-access memory.  The
+@code{gdsfmt} package offers efficient operations specifically designed for
+integers of less than 8 bits, since a diploid genotype, like
+@dfn{single-nucleotide polymorphism} (SNP), usually occupies fewer bits than a
+byte.  Data compression and decompression are available with relatively
+efficient random access.  It is also allowed to read a GDS file in parallel
+with multiple R processes supported by the package @code{parallel}.")
