Hi Bruce,
The Utils package is/was part of the "UniLib" collection that I used to
provide on a TWiki. However, because of (outside) abuse of the TWiki,
I've closed it down. UniLib is available as a gzipped tar file
from the main Unicon side via the "Interesting Links" link.
It can also be gotten directly via:
http://www2.cs.uidaho.edu/~jeffery/unicon/unilib.tar.gz
but may take some massaging.
The only use of the Utils package is in the argument handling (specifically
the Args class). It's probably easier to just roll your own argument handler.
(Not that it's relevant to the use here, but the change in implementation of
co-expressions to support threading has broken a few things in UniLib. The
version in the tar file predates that change and so some code may not work
without changes. I've fixed the ones that I've come across in my own use,
but will happily fix others should anyone stumble on them...)
