"""BLIS is a portable software framework for instantiating high-performance
BLAS-like dense linear algebra libraries.
The framework was designed to isolate essential kernels of computation
that, when optimized, immediately enable optimized implementations of
most of its commonly used and computationally intensive operations. BLIS
is written in ISO C99 and available under a new/modified/3-clause BSD
license. While BLIS exports a new BLAS-like API, it also includes a
BLAS compatibility layer which gives application developers access to
BLIS implementations via traditional BLAS routine calls.
An object-based API unique to BLIS is also available.
