Book automatic new page

I want to create a help book explaining some stuff. Longer passages obviously don’t fit on one page, so is there a convenient way to automatically make the text continue on the next page? The only way I found was to manually create a new page.

Thanks in advance!

There is no way to tell what the client’s current font and font size are. All that can be done is to figure out some sane character limit beforehand, and then use that.
