We have similar code in `config.sh`:
```bash
# Resolve links
this="$0"
while [ -h "$this" ]; do
ls=`ls -ld "$this"`
link=`expr "$ls" : '.*-> \(.*\)$'`
if expr "$link" : '.*/.*' > /dev/null; then
this="$link"
else
this=`dirname "$this"`/"$link"
fi
done
```
Does it make sense to have both scripts in sync as they try to do the same
thing?
