%description
    Syncthing pursues the following goals: Define a protocol for
    synchronization of a folder between a number of collaborating
    devices. This protocol should be well defined, unambiguous, easily
    understood, free to use, efficient, secure and language neutral.
    This is called the Block Exchange Protocol. Provide the reference
    implementation to demonstrate the usability of said protocol. This
    is the syncthing(1) utility.
