+  # Rack::URLMap takes a hash mapping urls or paths to apps, and
+  # dispatches accordingly.  Support for HTTP/1.1 host names exists if
+  # the URLs start with <tt>http://</tt> or <tt>https://</tt>.
+  #
+  # URLMap modifies the SCRIPT_NAME and PATH_INFO such that the part
+  # relevant for dispatch is in the SCRIPT_NAME, and the rest in the
+  # PATH_INFO.  This should be taken care of when you need to
+  # reconstruct the URL in order to create links.
+  #
+  # URLMap dispatches in such a way that the longest paths are tried
+  # first, since they are most specific.
