# Explanation of the various flags:

# --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.
