Sorry, it's not the same product.

zshell 0.001 is just the script below, but expect a much much more
powerful version in minutes.

I'll announce it there.

# This is the Zope shell, an attempt at making the most common
# Unix shell commands available from within Zope.
#
# As of May 3rd 2001, version 0.001, the following commands
# are recognized:
#
#       cd, rm, mv, cp, ls
#
# * cd accepts a single path as an argument
# * rm accepts many path arguments
# * mv and cp last argument is the destination folder, every previous
#   argument is an object id in the current folder
# * ls accepts many meta types as its arguments
#
# The future:
#
# in the future I'd be interested in adding more functionnalities
# as well as making it a complete Zope product, splitting it
# in one method per command, and making the accepted syntax much more
# match Unix shell's one.
# adding support for a find command is also high on my priority list
