Hey Michael,

Thanks for such a great post. Looks like it is time for me to learn how
to make working directories. :)

Do you have any more chemistry related schemes? I'm the only one
that I know of at my school with an HP in a sea of Ti's so I don't get
to swap tricks - but I do get to show off. :P
