[ale] HTML -> PS -> PDF

[cfowler at outpostsentinel.com (Chris Fowler)]

I'm creating a J2EE app in which the user can generate reports.  I want
to generate a report in HTML format and store in /tmp as temp file.  I
then want to somehow convert that to PDF maybe I have to go the PS
first.  

After I do that I will send their browser headers that indicate I'm
sending them a file.  The will then be prompted to save to disk or load
in Acrobat or in our (ale.org) case xpdf.

Any pointers?
