Multiline font-lock

[Jose A. Ortega Ruiz]

Hi,

I need multiline font lock in a major mode that i'm writing. I read in
the elisp manual (and have actually checked it) that using regexps
matching multiple lines in font-lock-keywords is a bad idea. I've also
read the node dedicated to multiline font-lock in the manual, but it's
not clear to me how it works. Could you please point me to an example of
that mechanism being used?

Thanks!
