minor correction/addition to previous post:

instead of "infinitely recursive", i should've
said that it would break things if "script"
re-exec's the same file with a
different interpreter.

> 	. script

this won't work if "script" is going to do something
before exec'ing the file itself.  it will end up
being infinitely recursive.  and similarly for
the following:
