Both command line scripts are shipped in both binary packages, but they have different extensions according to if they are running on current Python 2 or Python 3, namely "tls-python2" and "tlsdb-python2", next to "tls-python3" and "tlsdb-python3" in the other binary. Please regard that currently not all cryptographic libraries for acceleration of tlslite-ng are available for Python 3 (m2crypto and gmpy aren't). Daniel Stender
