The most elegant, open-source and completely free solution: use ghostscript.
$ gs -dBATCH -dNOPAUSE -q -sDEVICE=pdfwrite -sOutputFile=finished.pdf inputfile1.pdf inputfile2.pdf
ghostscript (gs) is pre-installed on most Linux distributions.

If you're on Microsoft Windows, have a look at pdftk, which I found via this discussion.
