Booklet printing - with enscript?

[Robert Moskowitz]

I have been using enscript to nicely print Internet draft .txt two up 
duplex,

enscript -2r --margins=:::45 -DDuplex:true -P HP-Officejet-Pro-8500 
draft-moskowitz-hip-rg-dex-06.txt

but it would be nice to do this in booklet form like I can get with a 
pdf with acrobat reader.

I looked at the enscript man, and did not see a way to do this. Anyone 
have experience with booklet printing?

Oh, I am still on F16.
