+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.")
