Yah.  Your "sourcing" explanation was much better.  I figured I hadn't 
explained it well.  All it does is simply run the script in the current 
shell instead of forking a child shell; one of the main side-effects is 
that any environment changes from the script happen in the current shell.

This does not work in, for instance, the C shell.  It *does* work in the 
Korn shell, though.  So, you must be careful not to "source" a Korn 
shell script in Bash shell.

Well, considering nobody uses the Korn shell anymore, I guess you don't 
have to be *that* careful.
