"""
Trivial RPKI up-down protocol root server, for testing. Not suitable
for production use. Overrides a bunch of method definitions from the
rpki.* classes in order to reuse as much code as possible.
Usage: python testroot.py [ { -c | --config } configfile ] [ { -h | --help } ]
Default configuration file is testroot.conf, override with --config option.
