+    (description
+     "Blosc is a high performance compressor optimized for binary
+data (i.e. floating point numbers, integers and booleans, although it can
+handle string data too).  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 main goal is not just
+to reduce the size of large datasets on-disk or in-memory, but also to
+accelerate memory-bound computations.
+
+C-Blosc2 is the new major version of C-Blosc, and is backward compatible with
+both the C-Blosc1 API and its in-memory format.  However, the reverse thing is
+generally not true for the format; buffers generated with C-Blosc2 are not
+format-compatible with C-Blosc1 (i.e. forward compatibility is not
+supported).")
