- * The strategy for the Match blocks is that the config file is parsed twice.

- * checked for syntax only.
- *
- * The second time is after a connection has been established but before

- * are ignored since they have already been processed. If the criteria in a
- * Match block is met, activep is set and the subsequent directives
- * processed and actioned until EOF or another Match block unsets it. Any
- * options set are copied into the main server config.
- *
- * Potential additions/improvements:
- * - Add Match support for pre-kex directives, eg Protocol, Ciphers.
- *
- * - Add a Tag directive (idea from David Leonard) ala pf, eg:
- * Match Address 192.168.0.*
- * Tag trusted
- * Match Group wheel
- * Tag trusted
- * Match Tag trusted
- * AllowTcpForwarding yes
- * GatewayPorts clientspecified
