"""
TLS client used in unit tests.
Usage: [sudo] ./unit_test_client.py [send_data [cipher_suite_code [version]]]

Start our TLS client, send our send_data, and terminate session with an Alert.
Optional cipher_cuite_code and version may be provided as hexadecimal strings
(e.g. c09e for TLS_DHE_RSA_WITH_AES_128_CCM and 0303 for TLS 1.2).
Reception of the exact send_data on the server is to be checked externally.
