linux - How to convert a 1 page PDF to a 2 page per sheet PDF?

I would like to print a PDF so that on the front of the first page are the first two pages, on the back the 3rd and 4th and so on.

-----------------          -----------------

|       |       |          |       |       |
|   1   |   2   |          |   3   |   4   |    . . .
|       |       |          |       |       |
|_______|_______|          |_______|_______|
 page 1 - front             page 1 - back

Because my printer using Linux fails to support manual duplex printing I'd thought, maybe I could edit the pdf in a according way.

But how?

Answer

In addition to what's been mentioned, PDFjam includes a command line tool, pdfnup which does this. (It makes use of the pdfpages package for PDFLaTeX underneath, which you can also use.)

If you prefer a GUI, jPDFtweak is another option.
