(description
"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. 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.")
