I have used these objects for a while but noticed recently that some of them
complain when receiving floats in a list. I notice this in the help files
which clearly suggest that floats are OK. Vtrim among several others is
complaining about floats. I tried to contact the authors and although the
objects are still available for download, emails for the authors are
missing. Norman Jaffe is the primary name I see. Perhaps he reads the list
he could respond.
