+opam-version: "2.0"
+synopsis: "Composable byte stream readers and writers for OCaml"
+description: """\
+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 intentionally
+separate away ressource management and the specifics of reading and
+writing bytes.
+
+Bytesrw distributed under the ISC license. It has no dependencies.
+
+Optional support for compressed, hashed and encrypted bytes depend, at
+your wish, on the C [`zlib`], [`libzstd`], [`blake3`], [`libmd`],
+[`xxhash`] and  [`mbedtls`] libraries.
