    longDescription = ''
      Libchop is a set of utilities and library for data backup and
      distributed storage.  Its main application is chop-backup, an
      encrypted backup program that supports data integrity checks,
      versioning at little cost, distribution among several sites,
      selective sharing of stored data, adaptive compression, and more.
      The library itself, which chop-backup builds upon, implements
      storage techniques such as content-based addressing, content hash
      keys, Merkle trees, similarity detection, and lossless compression.
      It makes it easy to combine them in different ways.  The
      ‘chop-archiver’ and ‘chop-block-server’ tools, illustrated in the
      manual, provide direct access to these facilities from the command
      line.  It is written in C and has Guile (Scheme) bindings.
