+TBLIS is a library and framework for performing tensor operations,
+especially tensor contraction, using native algorithms. In this
+context, native means that TBLIS does not translate tensor
+operations into matrix operations using the BLAS libraries.
+Instead, TBLIS uses the philosophy (and certain low-level kernels)
+of the BLIS framework to implement tensor contraction with
+essentially zero overhead compared to matrix multiplication. TBLIS
+also aims to offer a convenient C++ interface for tensors and
+tensor operations, as well as a stable C interface with high
+portability.
