+
+To use queryparse, you need one or more files containing pcap-formatted packet
+captures, such as those generated by tcpdump via the -w switch.
+
+Once you have such a file, call queryparse as follows:
+
+queryparse -i tcpdump.raw -o outputfile
+
+where "tcpdump.raw" is the name of the pcap-formatted packet capture file, and
+"outputfile" is the name you wish to call the saved output of queryparse.
+
+When queryparse finishes, it will print to STDOUT a count of each type of query
+encountered during its run. For example:
+
+Statistics:
+ A: 1175140
+ SOA: 23639
+ NAPTR: 113
+ NS: 1329
+ CNAME: 1667
+ NONE: 38
+ PTR: 186053
+ AAAA: 50858
+ ANY: 2117
+ SRV: 49470
+ KEY: 218
+ A6: 245
+ TXT: 24243
+ MX: 517510
+-------------------------
+ TOTAL: 2032640
+
+
+
+The resulting output is in a format suitable as input to resperf or dnsperf.
+For example:
+
+example.biz. A
+example.net. MX
+foo.example.tv. A
+example.enc. MX
+example[2].txt. MX
+foo.]. MX
+
+
+Note that there are both valid and invalid host names in the output: Neither
+queryparse nor resperf or dnsperf discriminate on the basis of a host name's
+adherence to RFCs. If the query was put on the wire and can be recognized as a
+properly-formed query, it will be saved. If this does not meet your needs, you
+may wish to parse the resulting output file to eliminate nonconforming host
+names.
