+ * The strategy for the Match blocks is that the config file is parsed twice.
+ *
+ * The first time is at startup. activep is initialized to 1 and the
+ * directives in the global context are processed and acted on. Hitting a
+ * Match directive unsets activep and the directives inside the block are
+ * checked for syntax only.
+ *
+ * The second time is after a connection has been established but before
+ * authentication. activep is initialized to 2 and global config directives
+ * 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
+ * [...]
+ *
+ * - Add a PermittedChannelRequests directive
