[ale] extract 1 or more pages from a pdf from the command line?

[lists at serioustechnology.com (Geoffrey)]

I need to break an existing pdf document into multiple documents. 
Ideally, I'd like to be able to do this from the command line, so I 
could script it.  Anyone know of a tool to do the extraction?
