[reportlab-users] Paragraphs and Spaces

[Rob Schall]

There probably is a better solution than this one, but since I'm still 
newer to reportlab, I just threw something together.

In short, I don't believe its possible. You have to break it up into 
several paragraphs. All of the numbered stuff I had in an array 
actually. Then I looped threw it and positioned all of that text about 
20points from the normal margin. The numbers were placed separately by 
getting the height of the paragraph about to be written and writing it 
at the left margin and at the top height of the paragraph.

Kind of a messy way to do it, but I don't figure out a better way to 
handle this.
