# This chunks allows certain parts of a wiki page to be hidden from the
# rest of the rendering pipeline. It should be run at the beginning
# of the pipeline in `wiki_content.rb`.
#
# An example use of this chunk is to markup double brackets or
# auto URI links:
#  <nowiki>Here are [[double brackets]] and a URI: www.uri.org</nowiki>
#
# The contents of the chunks will not be processed by any other chunk
# so the `www.uri.org` and the double brackets will appear verbatim.
