Hello all, I have read through all relevant posts on Prawn but found no mentioning (even in Prawn's own documentation) of headers and footers.

However, I did see a demo on Prawnto's own website about headers and footers. I copied the entire source of that demo just to see if it works but an error of undefined method "header" is complained about. Am I to understand that Prawn took out header and footer recently in the gem or is there something else I need to do first to use header and footer?

The demo page: http://cracklabs.com/prawnto/code/prawn_demos/source/text/flowing_text_with_header_and_footer

the part of code of concern:

Prawn::Document.generate("flow_with_headers_and_footers.pdf") do

header margin_box.top_left do text "Here's My Fancy Header", :size => 25, :align => :center
end

text "hello world!" end

And by header, just in case, I mean the snippets of words that appear usually at a corner of every page of a document. Like your account number in your bills pages.

thanks!
