      Yandex.Disk console client for Linux lets you manage files on Disk without
      using a window interface or programs that support WebDAV. The advantages
      of the console client compared to a WebDAV connection:
       * low system resource requirements;
       * faster file reading and writing speeds;
       * faster syncing with Disk's server;
       * no need to be constantly connected to work with files.
