(synopsis "Python wrapper for the Blosc2 data compressor library")
(description
"Blosc2 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.
Python-Blosc2 wraps the C-Blosc2 library, and it aims to leverage its new API
so as to support super-chunks, multi-dimensional arrays, serialization and
other features introduced in C-Blosc2.
Python-Blosc2 also reproduces the API of Python-Blosc and is meant to be able
to access its data, so it can be used as a drop-in replacement.")
