>&#13;     This function implements a sort algorithm that orders
     alphanumeric strings in the way a human being would.  This is
     described as a "natural ordering". An example of the difference
     between this algorithm and the regular computer string sorting
     algorithms (used in <A
HREF="function.sort.html"
><B
CLASS="function"
>sort()</B
></A
>) can be seen below:
