+ (description "Blosc is a high performance compressor optimized for binary
+data. It has been designed to transmit data to the processor cache faster
+than the traditional, non-compressed, direct memory fetch approach via a
+@code{memcpy()} system call.
+
+Blosc works well for compressing numerical arrays that contains data with
+relatively low entropy, like sparse data, time series, grids with
+regular-spaced values, etc.
+
+This Python package wraps the Blosc library.")
