+/*
+ ** HISTORY:
+ ** - Originally written by Adam Twiss <adam@zeus.co.uk>, March 1996
+ ** with input from Mike Belshe <mbelshe@netscape.com> and
+ ** Michael Campanella <campanella@stevms.enet.dec.com>
+ ** - Enhanced by Dean Gaudet <dgaudet@apache.org>, November 1997
+ ** - Cleaned up by Ralf S. Engelschall <rse@apache.org>, March 1998
+ ** - POST and verbosity by Kurt Sussman <kls@merlot.com>, August 1998
+ ** - HTML table output added by David N. Welton <davidw@prosa.it>, January 1999
+ ** - Added Cookie, Arbitrary header and auth support. <dirkx@webweaving.org>, April 1999
+ ** Version 1.3d
+ ** - Increased version number - as some of the socket/error handling has
+ ** fundamentally changed - and will give fundamentally different results
+ ** in situations where a server is dropping requests. Therefore you can
+ ** no longer compare results of AB as easily. Hence the inc of the version.
+ ** They should be closer to the truth though. Sander & <dirkx@covalent.net>, End 2000.
+ ** - Fixed proxy functionality, added median/mean statistics, added gnuplot
+ ** output option, added _experimental/rudimentary_ SSL support. Added
+ ** confidence guestimators and warnings. Sander & <dirkx@covalent.net>, End 2000
+ ** - Fixed serious int overflow issues which would cause realistic (longer
+ ** than a few minutes) run's to have wrong (but believable) results. Added
+ ** trapping of connection errors which influenced measurements.
+ ** Contributed by Sander Temme, Early 2001
+ ** Version 1.3e
+ ** - Changed timeout behavour during write to work whilst the sockets
+ ** are filling up and apr_write() does writes a few - but not all.
+ ** This will potentially change results. <dirkx@webweaving.org>, April 2001
+ ** Version 2.0.36-dev
+ ** Improvements to concurrent processing:
+ ** - Enabled non-blocking connect()s.
+ ** - Prevent blocking calls to apr_recv() (thereby allowing AB to
+ ** manage its entire set of socket descriptors).
+ ** - Any error returned from apr_recv() that is not EAGAIN or EOF
+ ** is now treated as fatal.
+ ** Contributed by Aaron Bannert, April 24, 2002
+ **
+ ** Version 2.0.36-2
+ ** Internalized the version string - this string is part
+ ** of the Agent: header and the result output.
+ **
+ ** Version 2.0.37-dev
+ ** Adopted SSL code by Madhu Mathihalli <madhusudan_mathihalli@hp.com>
+ ** [PATCH] ab with SSL support Posted Wed, 15 Aug 2001 20:55:06 GMT
+ ** Introduces four 'if (int == value)' tests per non-ssl request.
+ **
+ ** Version 2.0.40-dev
+ ** Switched to the new abstract pollset API, allowing ab to
+ ** take advantage of future apr_pollset_t scalability improvements.
+ ** Contributed by Brian Pane, August 31, 2002
+ **/
+
+/* Note: this version string should start with \d+[\d\.]* and be a valid
+ * string for an HTTP Agent: header when prefixed with 'ApacheBench/'.
+ * It should reflect the version of AB - and not that of the apache server
+ * it happens to accompany. And it should be updated or changed whenever
+ * the results are no longer fundamentally comparable to the results of
+ * a previous version of ab. Either due to a change in the logic of
+ * ab - or to due to a change in the distribution it is compiled with
+ * (such as an APR change in for example blocking).
