Hi Naveed,

Thanks very much for this, but it doesn't quite solve my problem.  I've got the following in my layout/main.tt

<html>
<head>
<title>[% title %]</title>
...

Now, since I'm using auto_page, the web designer can add pages as he sees fit and the routes will be created.  What I'd like him to be able to do is to set the title tags from within individual pages.  Eg in contact.tt:

[% title = 'Contact Us' %]

I had thought that the layouts would be using TT's wrapper functionality, which would enable this, but that's not the case.  So, my workaround is something like this in main.tt:

[% title = 'default title' %]

[% IF request.path == '/' %]
    [% title = 'home page title' %]
[% ELSIF request.path == '/contact' %]
    [% title = 'contact page title' %]
[% END %]

That gets the job done, but it's not nearly as clean as I'd like and I need to trust the web designer to get the syntax correct etc.  Is there a way to get Dancer::Template::TemplateToolkit to use a wrapper by default?  

Thanks,

Olaf
