+      (description "This package implements parallel block gzip.  For many
+formats, in particular genomics data formats, data are compressed in
+fixed-length blocks such that they can be easily indexed based on a (genomic)
+coordinate order, since typically each block is sorted according to this order.
+This allows for each block to be individually compressed (deflated), or more
+importantly, decompressed (inflated), with the latter enabling random retrieval
+of data in large files (gigabytes to terabytes).  @code{pbgzip} is not limited
+to any particular format, but certain features are tailored to genomics data
+formats when enabled.  Parallel decompression is somewhat faster, but the true
+speedup comes during compression.")
