# \brief  Example for hosting the genode.org website on Genode
# \author Norman Feske
# \date   2012-08-16
#
# This run script uses the lighttpd web server to host the genode.org website.
# When executed the first time, the genode.org website is downloaded to
# 'bin/genode_org/website'. When the web server is up, you may point your web
# browser to http://localhost:5555
