Robert wrote to me off-list because he wanted to give the rest of you a 
chance to come up with something.  I haven't heard anything, so maybe the 
interest isn't there, or maybe you were waiting to see how Robert would 
respond to my comments.  In case it was the latter, this is what he came 
up with next:

#!/bin/bash
( cd "${0%/*}" ; pwd -P )

That is very cool and it is similar to what we came up with on TCLUG. 
There are several little tricks worth adding though.  What happens if the 
filename or directory name begins with a minus sign?  How can we be sure 
that the bash builtin versions of cd and pwd are used?
