## pdfbook: Rearrange pages of one or more PDF files into 2-up signatures

## Author David Firth (http://go.warwick.ac.uk/dfirth), with help
## from Marco Pessotto

## This is a simple wrapper for pdfjam, version 2.08

## catches both --signature and --signature*

## If $signature is empty, we need to use a default:
##
if test -z "$signature" ; then
signature="--signature 4"
else
signature=""
fi
##
## Make the call to pdfjam:
##
if test -z "$shortedge"
then
exec pdfjam --booklet true --landscape --suffix book $signature "$@"
else

}
exec pdfjam --booklet true --landscape --suffix book $signature \
