-Email Methods Reference
-=======================
-
-$this->email->from()
---------------------
-
-Sets the email address and name of the person sending the email::
-
-	$this->email->from('you@example.com', 'Your Name');
-
-You can also set a Return-Path, to help redirect undelivered mail::
-
-	$this->email->from('you@example.com', 'Your Name', 'returned_emails@example.com');
-	
-.. note:: Return-Path can't be used if you've configured
-	'smtp' as your protocol.
-
-$this->email->reply_to()
-------------------------
-
-Sets the reply-to address. If the information is not provided the
-information in the "from" method is used. Example::
-
-	$this->email->reply_to('you@example.com', 'Your Name');
-
-$this->email->to()
-------------------
-
-Sets the email address(s) of the recipient(s). Can be a single email, a
-comma-delimited list or an array::
-
-	$this->email->to('someone@example.com');
-
-::
-
-	$this->email->to('one@example.com, two@example.com, three@example.com');
-
-::
-
-	$list = array('one@example.com', 'two@example.com', 'three@example.com');
-
-	$this->email->to($list);
-
-$this->email->cc()
-------------------
-
-Sets the CC email address(s). Just like the "to", can be a single email,
-a comma-delimited list or an array.
-
-$this->email->bcc()
--------------------
-
-Sets the BCC email address(s). Just like the "to", can be a single
-email, a comma-delimited list or an array.
-
-$this->email->subject()
------------------------
-
-Sets the email subject::
-
-	$this->email->subject('This is my subject');
-
-$this->email->message()
------------------------
-
-Sets the email message body::
-
-	$this->email->message('This is my message');
-
-$this->email->set_alt_message()
--------------------------------
-
-Sets the alternative email message body::
-
-	$this->email->set_alt_message('This is the alternative message');
-
-This is an optional message string which can be used if you send HTML
-formatted email. It lets you specify an alternative message with no HTML
-formatting which is added to the header string for people who do not
-accept HTML email. If you do not set your own message CodeIgniter will
-extract the message from your HTML email and strip the tags.
-
-$this->email->set_header()
---------------------------
-
-Appends additional headers to the e-mail::
-
-	$this->email->set_header('Header1', 'Value1');
-	$this->email->set_header('Header2', 'Value2');
-
-$this->email->clear()
----------------------
-
-Initializes all the email variables to an empty state. This method is
-intended for use if you run the email sending method in a loop,
-permitting the data to be reset between cycles.
-
-::
-
-	foreach ($list as $name => $address)
-	{
-		$this->email->clear();
-
-		$this->email->to($address);
-		$this->email->from('your@example.com');
-		$this->email->subject('Here is your info '.$name);
-		$this->email->message('Hi '.$name.' Here is the info you requested.');
-		$this->email->send();
-	}
-
-If you set the parameter to TRUE any attachments will be cleared as
-well::
-
-	$this->email->clear(TRUE);
-
-$this->email->send()
---------------------
-
-The Email sending method. Returns boolean TRUE or FALSE based on
-success or failure, enabling it to be used conditionally::
-
-	if ( ! $this->email->send())
-	{
-		// Generate error
-	}
-
-This method will automatically clear all parameters if the request was
-successful. To stop this behaviour pass FALSE::
-
- 	if ($this->email->send(FALSE))
- 	{
- 		// Parameters won't be cleared
- 	}
-
-.. note:: In order to use the ``print_debugger()`` method, you need
-	to avoid clearing the email parameters.
-
-$this->email->attach()
-----------------------
-
-Enables you to send an attachment. Put the file path/name in the first
-parameter. Note: Use a file path, not a URL. For multiple attachments
-use the method multiple times. For example::
-
-	$this->email->attach('/path/to/photo1.jpg');
-	$this->email->attach('/path/to/photo2.jpg');
-	$this->email->attach('/path/to/photo3.jpg');
-
-To use the default disposition (attachment), leave the second parameter blank,
-otherwise use a custom disposition::
-
-	$this->email->attach('image.jpg', 'inline');
-
-If you'd like to use a custom file name, you can use the third paramater::
-
-	$this->email->attach('filename.pdf', 'attachment', 'report.pdf');
-
-If you need to use a buffer string instead of a real - physical - file you can
-use the first parameter as buffer, the third parameter as file name and the fourth
-parameter as mime-type::
-
-	$this->email->attach($buffer, 'attachment', 'report.pdf', 'application/pdf');
-
-$this->email->print_debugger()
-------------------------------
-
-Returns a string containing any server messages, the email headers, and
-the email messsage. Useful for debugging.
-
-You can optionally specify which parts of the message should be printed.
-Valid options are: **headers**, **subject**, **body**.
-
-Example::
-
-	// You need to pass FALSE while sending in order for the email data
-	// to not be cleared - if that happens, print_debugger() would have
-	// nothing to output.
-	$this->email->send(FALSE);
-
-	// Will only print the email headers, excluding the message subject and body
-	$this->email->print_debugger(array('headers'));
-
-.. note:: By default, all of the raw data will be printed.
