   1 """
   2     MoinMoin - EmbedWikiPage a macro to embed a wiki page from a different wiki
   3     @license: GNU GPL, see COPYING for details.
   4 
   5     PURPOSE:
   6         This macro is used to embed a wiki page into the current wikipage.
   7 	It is possible to embed local pages as well as external wiki pages.
   8 
   9 	if a WikiName is detected the name is translated into a link to the original page.
  10 	On some circumstances a WikiName is not detected, see RESTRICTIONS.
  11 
  12         The page is embedded temporary and you get at the end a link to edit the original page.
  13 
  14 	At this stage it could be used to embed single pages e.g. macro explanaitions from moinmoin
  15 
  16     CALLING SEQUENCE:
  17        [[EmbedWikiPage(site,name)]]
  18 
  19 
  20     INPUTS:
  21        site: the URL of the wiki where the page is on
  22        name: the wikiname of the page
  23 
  24     EXAMPLE:
  25        [[EmbedWikiPage(http://moinmoin.wikiwikiweb.de:8000/,ProcessorMarket/sctable)]]
  26 
  27     PROCEDURE:
  28       * Editing of an embedded page is always editing the original page.
  29       * wiki:, wiki:/ or [" "] page and normal !WikiName links are followed to their original locations
  30       * attachments are embedded
  31 
  32       Please remove the version number from the routine name!
  33 
  34     RESTRICTIONS:
  35       * at the moment it follows nearly all wiki links
  36 
  37       I have a simple mechanism to detect wiki:, wiki:/ or ["HOWTO"] and normal !WikiName pagelinks
  38 
  39       At the moment I don't find !WikiName which are inserted into tabulars and macros.
  40 
  41       Later on it would be fine to use the icon of the page (favicon)
  42       to show where are the links from.
