+sharing tensors among frameworks.  DLPack enables
+@itemize
+@item Easier sharing of operators between deep learning frameworks.
+@item Easier wrapping of vendor level operator implementations, allowing
+collaboration when introducing new devices/ops.
+@item Quick swapping of backend implementations, like different version of
+BLAS
+@item For final users,this could bring more operators, and possibility of
+mixing usage between frameworks.
+@end itemize
+
+This package does not intend to implement Tensor and Ops, but instead use this
+as common bridge to reuse tensor and ops across frameworks.")
