# \brief  Example for hosting the genode.org website on Genode
# \author Norman Feske
# \date   2012-08-16
#
# This run script combines the lighttpd web server with the tar_fs file system
# 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
