This text can include <a href="http://docs.python.org/library/stdtypes.html#string-formatting-operations">Python format strings</a> which are resolved against list attributes. The list of substitutions allowed are: <ul> <li><b>real_name</b> - The "pretty" name of the list; usually the list name with capitalization. <li><b>list_name</b> - The name by which the list is identified in URLs, where case is significant. <li><b>host_name</b> - The fully qualified domain name that the list server runs on. <li><b>web_page_url</b> - The base URL for Mailman. This can be appended with, e.g. <em>listinfo/%(list_name)s</em> to yield the listinfo page for the mailing list. <li><b>description</b> - The brief description of the mailing list. <li><b>info</b> - The full description of the mailing list. <li><b>cgiext</b> - The extension added to CGI scripts. </ul>
