Hello to all.

I faced problem with the loading of the ExpressionManipulation package
from the David Park's
link.

Here are some of the messages I got.

Needs["Algebra`ExpressionManipulation`"]
MessageName::messg: Algebra`ExpressionManipulation::usage cannot be set
to 3\D. It must be set to a string.
Syntax::newl: The newline character after " =20" is understood as a
multiplication operator.
(line 260 of "Algebra`ExpressionManipulation`")
Syntax::sntx: Syntax error in or before "= ". (line 256 of
"Algebra`ExpressionManipulation`")

Does someone know what I did wrong?

Regards
Dimitris

The package files for Algebra`ExpressionManipulation` and
Algebra`Pushthrough` have been regenerated and put up at my web site. These
were old files dating from 2001 and 2002. At that time I believe there was a
problem in generating packages that worked across platforms, which has long
since been fixed by WRI. I 'm not certain if that was the exact cause but
anyway Dimitris now says that the newly generated packages work.

I can reliable reproduce what you're seeing if I evaluate

<<Algebra`ExpressionManipulation`

(or the corresponding Get expression) more than once at a single kernel
session. However, I'm not getting any error messages at all if I use

Needs["Algebra`ExpressionManipulation`"]

instead.
