__DATA__
I have the text of a play which I was to put into
a presentation. So I need to
split it up every 15 lines or so.

I had already stated to do this in vim by recording
a macro where I would
insert some special text say xñx (which I can then
parse upon) after I'd moved
down around 15 lines.

Can this be done in perl (more automatically I guess)?
Also does it complicate
things to not want to introduce the parsing marker
when the 15 line account
occurs in the middle of a paragraph?

Sorry for not having a good grasp of the parsing lingo
here, but hopefully
you get what I want to do.
