:$WikiWordCountMax:The maximum number of times to convert each WikiWord encountered on a page. Defaults to 1,000,000. Common settings for this variable are zero (disable WikiWord links) and one (convert only the first occurrence of each WikiWord).
$WikiWordCountMax = 0; # disable WikiWord links
$WikiWordCountMax = 1; # convert only first WikiWord

:$WikiWordCount:An array that allows the number of WikiWord conversions to be set on a per-WikiWord basis. The default is to use $WikiWordCountMax unless a value is set in this array. By default PmWiki sets $WikiWordCount['PmWiki']=1 to limit the number of conversions of "PmWiki".
$WikiWordCount['PhD']=0; # Don't convert "PhD"
$WikiWordCount['WikiWord']=5; # Convert WikiWord 5 times

1. the following lines keep a page from linking to itself
   $title = FmtPageName('$Title_',$pagename);
   $WikiWordCount[$title]=0;

:$PagePathFmt: !DocumentationToDo. But look at Cookbook:PagePaths for some ideas.

:$LinkPageExistsFmt:The (HTML) string to output for links to already existing wiki pages. Defaults to
<a class='wikilink' href='\$LinkUrl'>\$LinkText</a>

:$LinkPageCreateFmt:The (HTML) string to output for links to non-existent wiki pages. The default is to add a '?' after the link text with a link to the page edit/create form. Defaults to
<a class='createlinktext' href='\$PageUrl?action=edit'>\$LinkText</a>
<a class='createlink' href='\$PageUrl?action=edit'>?</a>

:$LinkPageCreateSpaceFmt:Same as $LinkPageCreateFmt, but used when the link text has a space in it.

:$LinkPageSelfFmt:The (HTML) string to output for self-referencing links (i.e. links to the page itself). Defaults to
<a class='selflink' href='\$LinkUrl'>\$LinkText</a>

:$UrlLinkFmt:The (HTML) string to output for URL-links that begin with 'http:', 'ftp:', etc. Defaults to
<a class='urllink' href='\$LinkUrl'>\$LinkText</a>

:$IMapLinkFmt: an array of link formats for various link "schemes". Not set as default.
->Examples of custom formats to allow different styling via classes:
->Links to http: standard url links:
$IMapLinkFmt['http:'] = "<a class='httplink urllink' href='\$LinkUrl'>\$LinkText</a>";
->Links to https: secure pages:
$IMapLinkFmt['https:'] = "<a class='httpslink urllink' href='\$LinkUrl'>\$LinkText</a>";
->Links to PmWiki: InterMap shortcut:
$IMapLinkFmt['PmWiki:'] = "<a class='pmwikilink urllink' href='\$LinkUrl'>\$LinkText</a>";
->Links to Cookbook: InterMap shortcut
$IMapLinkFmt['Cookbook:'] = "<a class='cookbooklink urllink' href='\$LinkUrl'>\$LinkText</a>";

:$InterMapFiles:An array consisting a list of files and pages containing InterMap entries to be loaded (see CustomInterMap).

:$MakePageNameFunction:Name of a custom function to replace `MakePageName(), which converts strings into valid page names.

:$MakePageNamePatterns:
: :$MakePageNamePatterns is an array of regular expression replacements that is used to map the page link in a free link such as [[free link]] into a page name. Currently the default sequence is:

    "/'/" => '',                           # strip single-quotes
    "/[^$PageNameChars]+/" => ' ',         # convert non-alnums to spaces
    "/((^|[^-\\w])\\w)/e" 
      => "strtoupper('$1')",               # initial caps after spaces
    "/ /" => ''                            # strip spaces
