How To Merge multiple files into a single PDF ?
 

Hi List ;

I have needs to merge a gnucash invoice which I can print to file as a .ps
(postscript file) and then use ps2pdf to create a pdf with a spreadsheet for
expenses and images of the receipts. I would like to push all this into a
single multi-page PDF to submit to my client for payment. Any ideas on how to
pull this off?

http://www.accesspdf.com/pdftk/ should be able to do the job.
