How can I include a tikzpicture on every page?

I would like to create a complicated document template (page should be framed, and have a table to hold document information both in the header and footer).

I was thinking of using something like:

```
\begin{tikzpicture}[remember picture,overlay]  
% complicated layout should be here, simple example is given below:  
% \node [xshift=1cm,yshift=1cm] at (current page.south west)  
% {This is an absolutely positioned text in the page};  
\end{tikzpicture}

```

Do you have any other suggestions on how to create such a template?
