I would like to use texexec to post-process a large pdf file, so  
as to
prepare it for double sided printing. The existing file has a large
left hand "margin" on each page, so as to allow binding.
I would like to change this so that odd (right) pages have a large
left margin, and even (left) pages a large right margin.
\setuppagenumbering[alternative=doublesided]
\setuplayout[horoffset=1cm]
\setuplayout[page]
\starttext
\copypages[document]
\stoptext
Thanks, that's great!
Is there an easy way to compensate for the original offset? The
original pdf has a large left margin and a small right one.
Replace 'page' with the name of your document.

\setuplayout[page]

\starttext

\getfiguredimensions[pages]

\dorecurse\noffigurepages
   {\hbox to \textwidth
      {\ifodd\recurselevel
         \hskip-2cm\externalfigure[pages][page=\recurselevel]\hss
       \else
         \hskip-1cm\externalfigure[pages][page=\recurselevel]\hss
       \fi}}

\stoptext
