Dialogue line numbers?

[mckea]

When working with an actor (and also when taking voice or text notes for edits) it's often useful to refer to a specific line of dialogue in a script. Might this be considered as a new rendering option?

On the printed page, this would render as sequential numbers somewhere on the same line as the character's name with each chunk of dialogue:

14                                ROBERT:
               I've told you a thousand times, I do not care for 
               sea urchins.

15                                WALTER:
               Given our current situation, I hardly think we can
               afford to picky!

16                                ROBERT:
               Listen Walt, I'm a kelp man - through and through!
               My father was a kelp man, and his father before him.

Scene numbering would also be useful.

For what output? In the HTML output, I think this may be doable using CSS only.

Personally, I usually distribute scripts as PDF. The more I think about it, I would probably be better off publishing in HTML to the project website and pass links around instead of documents!

But I assume you'd want to support this for all output formats?
