+
+Biniou (pronounced "be new") is a binary data format designed for speed, safety,
+ease of use and backward compatibility as protocols evolve. Biniou is vastly
+equivalent to JSON in terms of functionality but allows implementations several
+times faster (4 times faster than yojson), with 25-35% space savings.
+
+Biniou data can be decoded into human-readable form without knowledge of type
+definitions except for field and variant names which are represented by 31-bit
+hashes. A program named bdump is provided for routine visualization of biniou
+data files.
+
+The program atdgen is used to derive OCaml-Biniou serializers and deserializers
+from type definitions.

+
+This module offers a high-level and functional interface to the Format module of
+the OCaml standard library. It is a pretty-printing facility, i.e. it takes as
+input some code represented as a tree and formats this code into the most
+visually satisfying result, breaking and indenting lines of code where
+appropriate.
+
+Input data must be first modelled and converted into a tree using 3 kinds of
+nodes:
+
+* atoms
+* lists
+* labelled nodes
+
+Atoms represent any text that is guaranteed to be printed as-is. Lists can model
+any sequence of items such as arrays of data or lists of definitions that are
+labelled with something like "int main", "let x =" or "x:"."""

+Subject: [PATCH 1/4] add missing runtime dependencies in _tags
+
+Binaries in <bench/*>, <tests/*> depend on ppx_sexp_conv's runtime
+library within ppx_sexp_conv.
+
+The packed modules <src/nocrypto.cm{x,o}> also depend on the package
+ppx_sexp_conv: its presence at pack-creation time influences the
+generated .cmi interface, see
+
+  https://github.com/ocaml/opam-repository/pull/11628#issuecomment-375697444
+
+Note: the package ppx_sexp_conv.runtime-lib would suffice, but it is
+only available as such under recent ppx_sexp_conv versions, so its
+explicit use would make the build description (needlessly)
+incompatible with older ppx_sexp_conv versions.

+cstruct.4.0.0 work which makes sexplib optional.

+Do you get excited by C stubs? Do they sometimes make you swoon, and even faint,
+and in the end no `cmxa`s get properly linked -- not to mention correct
+multi-lib support?
+
+Do you wish that the things that excite you the most, would excite you just a
+little less? Then ocb-stubblr is just the library for you.
+
+ocb-stubblr is about ten lines of code that you need to repeat over, over, over
+and over again if you are using `ocamlbuild` to build OCaml projects that
+contain C stubs -- now with 100% more lib!
+
+It does what everyone wants to do with `.clib` files in their project
+directories. It can also clone the `.clib` and arrange for multiple compilations
+with different sets of discovered `cflags`.
+
+ocb-stubblr is distributed under the ISC license."""

+
+Transport Layer Security (TLS) is probably the most widely deployed security
+protocol on the Internet. It provides communication privacy to prevent
+eavesdropping, tampering, and message forgery. Furthermore, it optionally
+provides authentication of the involved endpoints. TLS is commonly deployed for
+securing web services ([HTTPS](http://tools.ietf.org/html/rfc2818)), emails,
+virtual private networks, and wireless networks.
+
+TLS uses asymmetric cryptography to exchange a symmetric key, and optionally
+authenticate (using X.509) either or both endpoints. It provides algorithmic
+agility, which means that the key exchange method, symmetric encryption
+algorithm, and hash algorithm are negotiated.
