Paragraph and documentation

Hello all. I just came across pdf::api2 and it appears to be what I 
have been looking for for a while now.

Is there any detailed documentation on all the commands? I have found 
many examples, but not a straight listing of all the commands.

I am interested in how to use the paragraph command to put text into a 
pdf instead of the single line command as that I assume (which could be 
a bad thing) it will take care of word wrap, justification etc.

Again - any / all help would be appreciated.
