A string prefix to be prepended to cookies set from Pm Wiki scripts. It defaults to '', but can be set to a different value to avoid conflicts with similar-named cookies from other applications, or to allow multiple wikis from the same domain to store separate cookies.
$CookiePrefix = 'pmwiki_'; # set cookie prefix to 'pmwiki_'
A string representing the release version of Pm Wiki, as in "pmwiki-2.1.40".
