Try to cope with Squeeze and Sid xetex problems. On Sid, "xdvipdfmx -p a5 -l" outputs its first page in A4 portrait. So guess which we're using and use the appropriate invocation.

#!/bin/sh

if [ $# != 1 ]; then
    echo "Usage: make.sh <book dir name>"
    exit 1
fi

booke=$1

find $booke -name "*.abc" | sort | xargs abcm2ps -F dottes.fmt -O $booke.ps
