How to overlay PDF to another PDF?

Question: I have PDF or postscript files (I can work with either one). What I want to do is merge each page on top of the other so that page1 of document A will be combined with page 1 of document B to produce page 1 of the output document. This isn't something I necessarily want need to do programmatically, although that would be helpful. Any ideas?

From this web page ( ), I downloaded the “PDF Toolbox Command Line” After I unzipped the file I could not find a “pdftoolbox” executable. I tried “Call_PDFToolBoxCom.exe”, but it just gave me three pdf advertisements (html2pdf.pdf, pg_0001.pdf and pg_0002.pdf).
