# Clear out namespaces and commands, leaving an empty interpreter

# needed to perform the deletions. We have to keep the 'rename'
# command until last to allow us to delete all ocmmands. We also
# have to defer deletion of the ::tcl namespace (if present), as
# it may contain state for the auto-loader, which may be
# invoked. This also forces us to defer the deletion of the
# builtin command 'namespace' so that we can delete ::tcl at last.
