+class Blis(Package):
+    """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."""
