+    (description
+     "Genome-wide association studies (GWAS) are widely used to investigate
+the genetic basis of diseases and traits, but they pose many computational
+challenges.  The R package SNPRelate provides a binary format for
+single-nucleotide polymorphism (SNP) data in GWAS utilizing CoreArray Genomic
+Data Structure (GDS) data files.  The GDS format offers the efficient
+operations specifically designed for integers with two bits, since a SNP could
+occupy only two bits.  SNPRelate is also designed to accelerate two key
+computations on SNP data using parallel computing for multi-core symmetric
+multiprocessing computer architectures: Principal Component Analysis (PCA) and
+relatedness analysis using Identity-By-Descent measures.  The SNP GDS format
+is also used by the GWASTools package with the support of S4 classes and
+generic functions.  The extended GDS format is implemented in the SeqArray
+package to support the storage of single nucleotide variations (SNVs),
+insertion/deletion polymorphism (indel) and structural variation calls in
+whole-genome and whole-exome variant data.")
