Yes, correct, but export does effect the shell that ran the script,
which is what I was trying (poorly) to say.  Obviously need to work on
that part some more.

My testing shows that using a relative path to the script works fine, 
even in the extreme case where GRAMPSHOME is just '.' (IF the script 
doesn't do a 'cd').  GRAMPS doesn't appear to ever do chdir, so that 
shouldn't be a problem.  So I removed the 'cd' and the warning about 
relative paths.

Awesome!  I never knew you could do that!
And your rename script is great.  I've really needed that a few times...

Anyway, I've put in all your suggestions and tried to improve the 
discussion of the environment stuff.  See how that looks to you.

Thanks for the improvements!
