This text can include Python format strings which are resolved against list attributes. The list of substitutions allowed are:
real_name - The `pretty' name of the list; usually
the list name with capitalization.
list_name - The name by which the list is
identified in URLs, where case is significant. (For backwards
compability, _internal_name is equivalent.)
host_name - The fully qualified domain name
that the list server runs on.
web_page_url - The base URL for Mailman. This
can be appended with,
e.g. listinfo/%(internal_name)s to yield the
listinfo page for the mailing list.
description - The brief description of the
mailing list.
info - The full description of the mailing
list.
cgiext - The extension added to CGI scripts.
