mirroring a website
wget --mirror --convert-links --adjust-extension --page-requisites --no-parent
--mirror– Makes (among other things) the download recursive.
--convert-links– convert all the links (also to stuff like CSS stylesheets) to relative, so it will be suitable for offline viewing.
--adjust-extension– Adds suitable extensions to filenames (html or css) depending on their content-type.
--page-requisites– Download things like CSS style-sheets and images required to properly display the page offline.
--no-parent– When recursing do not ascend to the parent directory. It useful for restricting the download to only a portion of the site.
--no-clobber, don't over-write if exist
--no-parent, when recursive, don't download from parent directories
--no-host-directories, disable generation of host-prefixed directories (don't put host name in directory name)
--relative, follow relative links only
--cut-dirs=2: shorten final directory name by cutting 2 first element from source
--no-verbose, less verbose but not fully quite as
