Usage Notes:
(2) If you are using Mathematica version 3.0 or later and
you
have already downloaded these packages, then you will have difficulty
unless
you do the following: In your favorite text editor, edit the program zeilutil.m.
Globally search and replace every occurrence of the string "Split"
by the string "Ssplit". Then edit the program algutil.m
and do the same replacement. (Alternatively, just download the updated
versions of all of these programs from the Web site at RISC-LINZ).
