Arragning pdf-pages

[Willi Egger <w.egger@boede.nl>]

Hi Hans,

When arranging pfd pages from a pdf file with the ruby version of the 
texexec script the following error occurs:

<cid:part1.07050109.01020703@boede.nl>texmfstart texexec.rb --pdfarrange 
--paper=a5a4 --print=2up --result=a5a4-artiplydoc artiply-doc.pdf

\calculatepaperoffsets ...lue {\??pp #1\c!offset }
                                                  \divide \scratchdimen

                                                  \xdef \papersize {A4}

                            \doprocesscommaitem

?

It does work with the perl script.
COuld you please have a look at this?

Thanks
