+      Bytesrw extends the OCaml Bytes module with composable, memory efficient,
+      byte stream readers and writers compatible with effect-based concurrency.
+
+      Except for byte slice life-times, these abstractions intentionnaly
+      separate away ressource management and the specifics of reading and
+      writing bytes.
