chutney has a non-obvious license

At the top of some of the python files in Chutney is this text:

# Copyright 2011 Nick Mathewson, Michael Stone
# Copyright 2013 The Tor Project
#
#  You may do anything with this work that copyright law would normally
#  restrict, so long as you retain the above notice(s) and this license
#  in all redistributed copies and derived works.  There is no warranty.

which some folks might recognize as the Tiny license.

But the work as a whole appears to have no license file. So e.g. tools/bootstrap-network.sh would sure look to be non open source software currently.

Can we add a license for the work as a whole?
