How to put current date in footer?

[Alain]

Hi NG

I'm trying to have a timestamp in the footer of every page. nice would
also be to have subversion revision as metainformation printed.
I'm quite new to Lilypnd...

How can I do that?

I've tried it the LaTeX way:
\paper{
  ...
  oddFooterMarkup = "Compiled: \today"
}

but like this it doesn't work.

Thanks
Alain
