+1, pending addressing minor comments
Looks like the changes in the external interface of the scripts are only
enhancements, but I am not completely sure that if a user has made extensive
changes to drill-env.sh file (I'd assume most users do not), that this patch
will ensure backward compatibility. I suggest we add a note to the release
notes for 1.8.
