+    """A standalone library for adding rotary embeddings to transformers in Pytorch,
+    following its success as relative positional encoding. Specifically it will make
+    rotating information into any axis of a tensor easy and efficient, whether they
+    be fixed positional or learned. This library will give you state of the art
+    results for positional embedding, at little costs."""
