/* Documentation

This convers an extract file from MediaWiki to pmwiki
Create the XML extract file as follows

1) In mediaWiki 
  a)Use the all pages option to list all your pages (http://www.mediawiki.org/wiki/Special:AllPages)
  b)Use the export as HTML option to extract pages in to a file http://www.mediawiki.org/wiki/Special:Export

2) rename that file Mwiki.xml and place it in the subdirectory cookbook/filemaker/ along with this file
3) create a directory called newpages at the top level and set security so you can write to it
4) run this file by including it in the config file
5) move the new files from 'newfiles' to the wiki.d directory

You may wish to move particular groups in which case only extract some of the files and change the $fcGroup variable below
