Re: Put a entry in first position

"""
This plugin injects an entry to the beginning of the entry_list (unless
the entry_list has no entries in it) that lists some vital information.

It requires you to set "section_body_allowed_flavour_list" to the
list of flavours that you want this to inject an entry for.

ex:
   py["section_body_flavour_list"] = ["html", "xhtml"]
