# Test various options that are not covered by compat.sh
#
# Here the goal is not to cover every ciphersuite/version, but
# rather specific options (max fragment length, truncated hmac, etc)
# or procedures (session resumption from cache or ticket, renego, etc).
#
# Assumes all options are compiled in.
