# This script assumes that the documents to be served are .rhtml files in the
# directory one level up from the one where the script is located.  A layout
# template named "layouts/default.rhtml" is also assumed to exist in that
# directory.
#
# Of course, this script is completely out of date and incompatible with modern
# versions of ActionPack. I might someday fix this code, but right now my
# efforts are instead directed toward developing Silkweave
# (http://nanoo.org/software/silkweave/), which is a more complete and
# sophisticated realization of the ideas explored in this script.
