-/* Plugin for jQuery for working with colors.
- * 
- * Version 1.1.
- * 
- * Inspiration from jQuery color animation plugin by John Resig.
- *
- * Released under the MIT license by Ole Laursen, October 2009.
- *
- * Examples:
- *
- *   $.color.parse("#fff").scale('rgb', 0.25).add('a', -0.5).toString()
- *   var c = $.color.extract($("#mydiv"), 'background-color');
- *   console.log(c.r, c.g, c.b, c.a);
- *   $.color.make(100, 50, 25, 0.4).toString() // returns "rgba(100,50,25,0.4)"
- *
- * Note that .scale() and .add() return the same modified object
- * instead of making a new one.
- *
- * V. 1.1: Fix error handling so e.g. parsing an empty string does
- * produce a color rather than just crashing.

-.Op Fl c Ar file
-.Op Fl g Ar directives
-.Op Fl p Ar prefix
-.Op Fl s Ar signal
-.Sh DESCRIPTION
-.Nm
-(pronounced
-.Dq engine x )
-is an HTTP and reverse proxy server, as well as a mail proxy server.
-It is known for its high performance, stability, rich feature set, simple
-configuration, and low resource consumption.
-.Pp
-The options are as follows:
-.Bl -tag -width ".Fl d Ar directives"
-.It Fl ?\& , h
-Print help.
-.It Fl c Ar file
-Use an alternative configuration
-.Ar file .
-.It Fl g Ar directives
-Set global configuration directives.
-See
-.Sx EXAMPLES
-for details.
-.It Fl p Ar prefix
-Set the prefix path.
-The default value is
-.Pa %%PREFIX%% .
-.It Fl q
-Suppress non-error messages during configuration testing.
-.It Fl s Ar signal
-Send a signal to the master process.
-The argument
-.Ar signal
-can be one of:
-.Cm stop , quit , reopen , reload .
-The following table shows the corresponding system signals:
-.Pp
-.Bl -tag -width ".Cm reopen" -compact
-.It Cm stop
-.Dv SIGTERM
-.It Cm quit
-.Dv SIGQUIT
-.It Cm reopen
-.Dv SIGUSR1
-.It Cm reload
-.Dv SIGHUP
-.El
-.It Fl t
-Do not run, just test the configuration file.
-.Nm
-checks the configuration file syntax and then tries to open files
-referenced in the configuration file.
-.It Fl V
-Print the
-.Nm
-version, compiler version, and
-.Pa configure
-script parameters.
-.It Fl v
-Print the
-.Nm
-version.
-.El
-.Sh SIGNALS
-The master process of
-.Nm
-can handle the following signals:
-.Pp
-.Bl -tag -width ".Dv SIGINT , SIGTERM" -compact
-.It Dv SIGINT , SIGTERM
-Shut down quickly.
-.It Dv SIGHUP
-Reload configuration, start the new worker process with a new
-configuration, and gracefully shut down old worker processes.
-.It Dv SIGQUIT
-Shut down gracefully.
-.It Dv SIGUSR1
-Reopen log files.
-.It Dv SIGUSR2
-Upgrade the
-.Nm
-executable on the fly.
-.It Dv SIGWINCH
-Shut down worker processes gracefully.
-.El
-.Pp
-While there is no need to explicitly control worker processes normally,
-they support some signals too:
-.Pp
-.Bl -tag -width ".Dv SIGINT , SIGTERM" -compact
-.It Dv SIGTERM
-Shut down quickly.
-.It Dv SIGQUIT
-Shut down gracefully.
-.It Dv SIGUSR1
-Reopen log files.
-.El
-.Sh DEBUGGING LOG
-To enable a debugging log, reconfigure
-.Nm
-to build with debugging:
-.Pp
-.Dl "./configure --with-debug ..."
-.Pp
-and then set the
-.Cm debug
-level of the
-.Va error_log :
-.Pp
-.Dl "error_log /path/to/log debug;"
-.Pp
-It is also possible to enable the debugging for a particular IP address:
-.Bd -literal -offset indent
-events {
-	debug_connection 127.0.0.1;
-}
-.Ed
-.Sh ENVIRONMENT
-The
-.Ev NGINX
-environment variable is used internally by
-.Nm
-and should not be set directly by the user.
-.Sh FILES
-.Bl -tag -width indent
-.It Pa %%PID_PATH%%
-Contains the process ID of
-.Nm .
-The contents of this file are not sensitive, so it can be world-readable.
-.It Pa %%CONF_PATH%%
-The main configuration file.
-.It Pa %%ERROR_LOG_PATH%%
-Error log file.
-.El
-.Sh EXIT STATUS
-Exit status is 0 on success, or 1 if the command fails.
-.Sh EXAMPLES
-Test configuration file
-.Pa ~/mynginx.conf
-with global directives for PID and quantity of worker processes:
-.Bd -literal -offset indent
-nginx -t -c ~/mynginx.conf \e
-	-g "pid /var/run/mynginx.pid; worker_processes 2;"

- * Although FreeBSD sendfile() allows to pass a header and a trailer,
- * it cannot send a header with a part of the file in one packet until
- * FreeBSD 5.3.  Besides, over the fast ethernet connection sendfile()
- * may send the partially filled packets, i.e. the 8 file pages may be sent
- * as the 11 full 1460-bytes packets, then one incomplete 324-bytes packet,
- * and then again the 11 full 1460-bytes packets.
- *
- * Therefore we use the TCP_NOPUSH option (similar to Linux's TCP_CORK)
- * to postpone the sending - it not only sends a header and the first part of
- * the file in one packet, but also sends the file pages in the full packets.
- *
- * But until FreeBSD 4.5 turning TCP_NOPUSH off does not flush a pending
- * data that less than MSS, so that data may be sent with 5 second delay.
- * So we do not use TCP_NOPUSH on FreeBSD prior to 4.5, although it can be used
- * for non-keepalive HTTP connections.
