The daemon through which all knowledge passes.\n\n### Peers\n\nPeers are connected `fqd` processes.  It is important to note that peers are unidirectional.  If A peers with B, then A will act as a client to B. If you want bidirectional peering, you must specify that A peers with B and B peers with A.  The system aims to prevent cyclic delivery of messages efficiently.\n\nAdding peers is done directly via fqd\u0027s sqlite DB store:\n\n```\n; sqlite3 /var/lib/fq/fqd.sqlite\nsqlite\u003e INSERT INTO \"upstream\"\n              (host, port, source, password, exchange, program, permanent_binding)\n        VALUES(\u0027peerB\u0027,8765,\u0027fqd-peera//mem:drop,private,backlog=4096\u0027,\u0027none\u0027,\u0027logging\u0027,\u0027prefix:\"http.access.json.\"\u0027,\u0027false\u0027);\n```\n\n### Client\n\n * [C client - libfq](https://github.com/postwait/fq/blob/master/fq.h#L164-L205)\n * [Java client - fq.jar](https://github.com/postwait/fq/blob/master/java/src/com/omniti/labs/FqClientImplInterfac",
