* #27232: jni: added pjproject checkout as regular git content
We will remove it once the next release of pjsip (with Android support)
comes out and is merged into SFLphone.

+ *
+ * This module provides low-level services to parse and packetize DNS queries
+ * and responses. The functions support building a DNS query packet and parse
+ * the data in the DNS response. This implementation conforms to the
+ * following specifications:
+ * - RFC 1035: DOMAIN NAMES - IMPLEMENTATION AND SPECIFICATION
+ * - RFC 1886: DNS Extensions to support IP version 6
+ *
+ * To create a DNS query packet, application should call #pj_dns_make_query()
+ * function, specifying the desired DNS query type, the name to be resolved,
+ * and the buffer where the DNS packet will be built into.
+ *
+ * When incoming DNS query or response packet arrives, application can use
+ * #pj_dns_parse_packet() to parse the TCP/UDP payload into parsed DNS packet
+ * structure.
+ *
+ * This module does not provide any networking functionalities to send or
+ * receive DNS packets. This functionality should be provided by higher layer
+ * modules such as @ref PJ_DNS_RESOLVER.
