This seems to be close to what I need. A few questions.
this doesn't seem to account for if i have /foo/test and
/bar/test and sync them it still copies test over.  I
only want it to copy if they have changed or if it doesn't
exist.  Also would be ince if I was trying to sync /foo to
/bar if it would delete all files if /bar that were not
in /foo.

I will try building on what you sent me though, one question
what is the shift for I am not familiar with that.
