[pmwiki-devel] $zz in defintion for (:title ... :)

[Stirling Westrup]

I was just reading through the PmWiki code trying to figure out how to
do something, and I noticed the definition of the (:title ... :)
directive goes like this:

## (:title:)
Markup('title','>&',
  '/\\(:title\\s(.*?):\\)/ei',
  "PZZ(PCache(\$pagename,
         \$zz=array('title' => SetProperty(\$pagename, 'title',
PSS('$1')))))");

Can anyone tell me why that \$zz is in there?
