PdfNewGetFooterLinks shows that @NoLinkToPdf is simply a list of pages
that should not offer a PDF link at the bottom. Authors can add their
own exceptions to PdfNewGetFooterLinks, I guess, but in order to do
this from your config file, use vars.
createPDF needs $id as a parameter in order to use it. This code
worked before because the calling context was missing a my $id and
thus $id ended up being a global variable.
Replaced the $Id$ tags in $WikiDescription for all the modules and wiki.pl itself with a link to the source and an appropriate wiki page, if possible. This is shown in action=version and should help users figure out what another wiki has installed.
