      Designed and written from scratch it wraps around libwget, that provides the basic
      functions needed by a web client.
      Wget2 works multi-threaded and uses many features to allow fast operation.
      In many cases Wget2 downloads much faster than Wget1.x due to HTTP2, HTTP compression,
      parallel connections and use of If-Modified-Since HTTP header.
