+# Kohana-Cron
+
+This module provides a way to schedule tasks (jobs) within your Kohana application.
+
+
+## Installation
+
+Step 1: Download the module into your modules subdirectory.
+
+Step 2: Enable the module in your bootstrap file:
+
+	/**
+	 * Enable modules. Modules are referenced by a relative or absolute path.
+	 */
+	Kohana::modules(array(
+		'cron'       => MODPATH.'cron',
+		// 'auth'       => MODPATH.'auth',       // Basic authentication
+		// 'codebench'  => MODPATH.'codebench',  // Benchmarking tool
+		// 'database'   => MODPATH.'database',   // Database access
+		// 'image'      => MODPATH.'image',      // Image manipulation
+		// 'orm'        => MODPATH.'orm',        // Object Relationship Mapping
+		// 'pagination' => MODPATH.'pagination', // Paging of results
+		// 'userguide'  => MODPATH.'userguide',  // User guide and API documentation
+	));
+
+
+Step 3: Make sure the settings in `config/cron.php` are correct for your environment.
+If not, copy the file to `application/config/cron.php` and change the values accordingly.
+
+
+## Usage
+
+In its simplest form, a task is a [PHP callback][1] and times at which it should run.
+To configure a task call `Cron::set($name, array($frequency, $callback))` where
+`$frequency` is a string of date and time fields identical to those found in [crontab][2].
+For example,
+
+	Cron::set('reindex_catalog', array('@daily', 'Catalog::regenerate_index'));
+	Cron::set('calendar_notifications', array('*/5 * * * *', 'Calendar::send_emails'));
+
+Configured tasks are run with their appropriate frequency by calling `Cron::run()`. Call
+this method in your bootstrap file, and you're done!
+
+
+## Advanced Usage
+
+A task can also be an instance of `Cron` that extends `next()` and/or `execute()` as
+needed. Such a task is configured by calling `Cron::set($name, $instance)`.
+
+If you have access to the system crontab, you can run Cron less (or more) than once
+every request. You will need to modify the lines where the request is handled in your
+bootstrap file to prevent extraneous output. The default is:
+
+	/**
+	 * Execute the main request. A source of the URI can be passed, eg: $_SERVER['PATH_INFO'].
+	 * If no source is specified, the URI will be automatically detected.
+	 */
+	echo Request::instance()
+		->execute()
+		->send_headers()
+		->response;
+
+Change it to:
+
+	if ( ! defined('SUPPRESS_REQUEST'))
+	{
+		/**
+		 * Execute the main request. A source of the URI can be passed, eg: $_SERVER['PATH_INFO'].
+		 * If no source is specified, the URI will be automatically detected.
+		 */
+		echo Request::instance()
+			->execute()
+			->send_headers()
+			->response;
+	}
+
+Then set up a system cron job to run your application's Cron once a minute:
+
+	* * * * * /usr/bin/php -f /path/to/kohana/modules/cron/run.php
+
+The included `run.php` should work for most cases, but you are free to call `Cron::run()`
+in any way you see fit.

+Email Module For Kohana 3.0
+=================================
+
+This is a direct port of the email helper from Kohana 2.3.3 source code.
+
+It has been updated to work with SwiftMailer 4 and includes the libs dir from the 4.0.4 distribution.
+
+Usage should be exactly as with old helper.
+
+Methods defined:
+
+### Email::connect($config = NULL)
+
+Creates SwiftMailer object. $config is an array of configuration values and defaults to using the config file 'email'.
+
+Note: PopBeforeSmtp is not supported in this release as I didn't know what was required to set it up.
+It IS supported in Swiftmailer through the Swift_Plugins_PopBeforeSmtpPlugin plugin class. This can be used manually if required.
+If anyone can modify and test the connect() methd with this functionality I'll add it but I can't find documentation about how it used to work (i.e. is expected to work) so I have left it out for now.
+
+### Email::send($to, $from, $subject, $message, $html = false)
+
+$to can be any of the following:
+
+*  a single string email address e.g. "test@example.com"
+*  an array specifying an email address and a name e.g. array('test@example.com', 'John Doe')
+*  an array of recipients in either above format, keyed by type e.g. array('to' => 'test@example.com', 'cc' => array('test2@example.com', 'Jane Doe'), 'bcc' => 'another@example.com')
+
+$from can be either a string email or array of email and name as above
+
+More complex email (multipart, attachments, batch mailing etc.) must be done using the native Swift_Mailer classes. The Swift Mailer autoloader is included by connect() so you can use and class in the Swift library without worrying about including files.
+
+The Swift_Mailer object setup by connect is returned by it so if you need to access it manually use:
+
+        $mailer = Email::connect();
+
+        // Create complex Swift_Message object stored in $message
+
+        $mailer->send($message);

+
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+
+  This version of the GNU Lesser General Public License incorporates
+the terms and conditions of version 3 of the GNU General Public
+License, supplemented by the additional permissions listed below.
+
+  0. Additional Definitions. 
+
+  As used herein, "this License" refers to version 3 of the GNU Lesser
+General Public License, and the "GNU GPL" refers to version 3 of the GNU
+General Public License.
+
+  "The Library" refers to a covered work governed by this License,
+other than an Application or a Combined Work as defined below.
+
+  An "Application" is any work that makes use of an interface provided
+by the Library, but which is not otherwise based on the Library.
+Defining a subclass of a class defined by the Library is deemed a mode
+of using an interface provided by the Library.
+
+  A "Combined Work" is a work produced by combining or linking an
+Application with the Library.  The particular version of the Library
+with which the Combined Work was made is also called the "Linked
+Version".
+
+  The "Minimal Corresponding Source" for a Combined Work means the
+Corresponding Source for the Combined Work, excluding any source code
+for portions of the Combined Work that, considered in isolation, are
+based on the Application, and not on the Linked Version.
+
+  The "Corresponding Application Code" for a Combined Work means the
+object code and/or source code for the Application, including any data
+and utility programs needed for reproducing the Combined Work from the
+Application, but excluding the System Libraries of the Combined Work.
+
+  1. Exception to Section 3 of the GNU GPL.
+
+  You may convey a covered work under sections 3 and 4 of this License
+without being bound by section 3 of the GNU GPL.
+
+  2. Conveying Modified Versions.
+
+  If you modify a copy of the Library, and, in your modifications, a
+facility refers to a function or data to be supplied by an Application
+that uses the facility (other than as an argument passed when the
+facility is invoked), then you may convey a copy of the modified
+version:
+
+   a) under this License, provided that you make a good faith effort to
+   ensure that, in the event an Application does not supply the
+   function or data, the facility still operates, and performs
+   whatever part of its purpose remains meaningful, or
+
+   b) under the GNU GPL, with none of the additional permissions of
+   this License applicable to that copy.
+
+  3. Object Code Incorporating Material from Library Header Files.
+
+  The object code form of an Application may incorporate material from
+a header file that is part of the Library.  You may convey such object
+code under terms of your choice, provided that, if the incorporated
+material is not limited to numerical parameters, data structure
+layouts and accessors, or small macros, inline functions and templates
+(ten or fewer lines in length), you do both of the following:
+
+   a) Give prominent notice with each copy of the object code that the
+   Library is used in it and that the Library and its use are
+   covered by this License.
+
+   b) Accompany the object code with a copy of the GNU GPL and this license
+   document.
+
+  4. Combined Works.
+
+  You may convey a Combined Work under terms of your choice that,
+taken together, effectively do not restrict modification of the
+portions of the Library contained in the Combined Work and reverse
+engineering for debugging such modifications, if you also do each of
+the following:
+
+   a) Give prominent notice with each copy of the Combined Work that
+   the Library is used in it and that the Library and its use are
+   covered by this License.
+
+   b) Accompany the Combined Work with a copy of the GNU GPL and this license
+   document.
+
+   c) For a Combined Work that displays copyright notices during
+   execution, include the copyright notice for the Library among
+   these notices, as well as a reference directing the user to the
+   copies of the GNU GPL and this license document.
+
+   d) Do one of the following:
+
+       0) Convey the Minimal Corresponding Source under the terms of this
+       License, and the Corresponding Application Code in a form
+       suitable for, and under terms that permit, the user to
+       recombine or relink the Application with a modified version of
+       the Linked Version to produce a modified Combined Work, in the
+       manner specified by section 6 of the GNU GPL for conveying
+       Corresponding Source.
+
+       1) Use a suitable shared library mechanism for linking with the
+       Library.  A suitable mechanism is one that (a) uses at run time
+       a copy of the Library already present on the user's computer
+       system, and (b) will operate properly with a modified version
+       of the Library that is interface-compatible with the Linked
+       Version. 
+
+   e) Provide Installation Information, but only if you would otherwise
+   be required to provide such information under section 6 of the
+   GNU GPL, and only to the extent that such information is
+   necessary to install and execute a modified version of the
+   Combined Work produced by recombining or relinking the
+   Application with a modified version of the Linked Version. (If
+   you use option 4d0, the Installation Information must accompany
+   the Minimal Corresponding Source and Corresponding Application
+   Code. If you use option 4d1, you must provide the Installation
+   Information in the manner specified by section 6 of the GNU GPL
+   for conveying Corresponding Source.)
+
+  5. Combined Libraries.
+
+  You may place library facilities that are a work based on the
+Library side by side in a single library together with other library
+facilities that are not Applications and are not covered by this
+License, and convey such a combined library under terms of your
+choice, if you do both of the following:
+
+   a) Accompany the combined library with a copy of the same work based
+   on the Library, uncombined with any other library facilities,
+   conveyed under the terms of this License.
+
+   b) Give prominent notice with the combined library that part of it
+   is a work based on the Library, and explaining where to find the
+   accompanying uncombined form of the same work.
+
+  6. Revised Versions of the GNU Lesser General Public License.
+
+  The Free Software Foundation may publish revised and/or new versions
+of the GNU Lesser General Public License from time to time. Such new
+versions will be similar in spirit to the present version, but may
+differ in detail to address new problems or concerns.
+
+  Each version is given a distinguishing version number. If the
+Library as you received it specifies that a certain numbered version
+of the GNU Lesser General Public License "or any later version"
+applies to it, you have the option of following the terms and
+conditions either of that published version or of any later version
+published by the Free Software Foundation. If the Library as you
+received it does not specify a version number of the GNU Lesser
+General Public License, you may choose any version of the GNU Lesser
+General Public License ever published by the Free Software Foundation.
+
+  If the Library as you received it specifies that a proxy can decide
+whether future versions of the GNU Lesser General Public License shall
+apply, that proxy's public statement of acceptance of any version is
+permanent authorization for you to choose that version for the
+Library.

+Swift Mailer, by Chris Corbyn
+-----------------------------
+
+Swift Mailer is a component based mailing solution for PHP 5.
+It is released under the LGPL license.
+
+Homepage:      http://swiftmailer.org
+Documentation: http://swiftmailer.org/docs
+Mailing List:  http://groups.google.com/group/swiftmailer
+Bugs:          http://swiftmailer.lighthouseapp.com/
+Repository:    http://github.com/swiftmailer/swiftmailer
+
+Swift Mailer is highly object-oriented by design and lends itself
+to use in complex web application with a great deal of flexibility.
+
+For full details on usage, see the documentation.
+
+IMPORTANT: Users upgrading from version 3.x or earlier absolutely
+           MUST read the documentation.  In short, the API is considerably
+           different so your old code won't "just work".
+
+If you'd like to make a donation, we are working on a system where
+donations are taken on a per-feature-request basis via the website
+with target amounts for each feature. In the meantime however you
+may donate directly to the author via PayPal:
+
+  PayPal: chris@w3style.co.uk
+
+Donations are certainly voluntary, but seriously, you donors are
+complete legends and drive this project! :)
