+\`configure' configures this package to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE. See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+ -h, --help display this help and exit
+ --help=short display options specific to this package
+ --help=recursive display the short help of all the included packages
+ -V, --version display version information and exit
+ -q, --quiet, --silent do not print \`checking ...' messages
+ --cache-file=FILE cache test results in FILE [disabled]
+ -C, --config-cache alias for \`--cache-file=config.cache'
+ -n, --no-create do not create output files
+ --srcdir=DIR find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+ --prefix=PREFIX install architecture-independent files in PREFIX
+ [$ac_default_prefix]
+ --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
+ [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.
+
+Fine tuning of the installation directories:
+ --bindir=DIR user executables [EPREFIX/bin]

+ * TCP DNS perf tool
+ *
+ * main parameters are -r<rate> and <server>
+ * standard options are 4|6 (IPv4|IPv6), rate computations, terminaisons,
+ * EDNS0, NOERROR|NXDOMAIN, template (for your own query), diags,
+ * alternate server port and UDP version.
+ *
+ * To help to crush kernels (unfortunately both client and server :-)
+ * this version of the tool is multi-threaded:
+ * - the master thread inits, monitors the activity each millisecond,
+ * and report results when finished
+ * - the connecting thread computes the date of the next connection,
+ * creates a socket, makes it non blocking, binds it if wanted,
+ * connects it and pushes it on the output epoll queue
+ * - the sending thread gets by epoll connected sockets, timeouts
+ * embryonic connections, sends queries and pushes sockets on
+ * the input epoll queue
+ * - the receiving thread gets by epoll sockets with a pending
+ * response, receives responses, timeouts unanswered queries,
+ * and recycles (by closing them) all sockets.
+ *
+ * Rate computation details:
+ * - the target rate is in query+response per second.
+ * - rating is done by the connecting thread.
+ * - of course the tool is always late so the target rate is never
+ * reached. BTW there is no attempt to internally adjust the
+ * effective rate to the target one: this must be by tuning
+ * the rate related parameters, first the -r<rate> itself.
+ * - at the beginning of the connecting thread iteration loop
+ * (second "loops" counter) the date of the due (aka next) connect()
+ * call is computed from the last one with 101% of the rate.
+ * - the due date is compared with the current date (aka now).
+ * - if the due is before, lateconn counter is incremented, else
+ * the thread sleeps for the difference,
+ * - the next step is to reget the current date, if it is still
+ * before the due date (e.g., because the sleep was interrupted)
+ * the first shortwait counter is incremented.
+ * - if it is after (common case) the number of connect calls is
+ * computed from the difference between now and due divided by rate,
+ * rounded to the next number,
+ * - this number of connect() calls is bounded by the -a<aggressiveness>
+ * parameter to avoid too many back to back new connection attempts.
+ * - the compconn counter is incremented, errors (other than EINPROGRESS
+ * from not blocking connect()) are printed. When an error is
+ * related to a local limit (e.g., EMFILE, EADDRNOTAVAIL or the
+ * internal ENOMEM) the locallimit counter is incremented.
