    # Construct a link to +url_fragment+, which should be given relative to
    # the base of this Sinatra app.  The mode should be either
    # <code>:path_only</code>, which will generate an absolute path within
    # the current domain (the default), or <code>:full</code>, which will
    # include the site name and port number.  (The latter is typically
    # necessary for links in RSS feeds.)  Example usage:
    #
    #   url_for "/"            # Returns "/myapp/"
    #   url_for "/foo"         # Returns "/myapp/foo"
    #   url_for "/foo", :full  # Returns "http://example.com/myapp/foo"

    # up earlier versions of this code.
