    (description
     "fstrm is an optimised implementation of Frame Streams as a C library and
several tools built on top of it.

@dfn{Frame Streams} is a light-weight, binary-clean protocol that allows for
the transport of arbitrarily-encoded data payload sequences with minimal
framing overhead---just four bytes per data frame.  It does not specify an
encoding format for these data frames and can be used with any data
serialisation format that produces byte sequences, such as Protocol Buffers,
XML, JSON, MessagePack, YAML, etc.

Frame Streams can be used either as a streaming transport over a reliable byte
stream socket (TCP sockets, TLS connections, @code{AF_UNIX} sockets, etc.) for
data in motion, or as a file format for data at rest.")
