Revise Markdown handling of character entities. Ideally I'd like the ABC character entities to survive Markdown and then get converted. But because they start with '\', they don't. So I have no alternative but to convert them to HTML entities, which Markdown then converts to UTF-8.

#!/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
