+
+PHP Markdown Extra
+==================
+
+Description
+-----------
+
+This is a PHP port of the original Markdown formatter written in Perl 
+by John Gruber. This special "Extra" version of PHP Markdown features 
+further enhancements to the syntax for making additional constructs 
+such as tables and definition list.
+
+Markdown is a text-to-HTML filter; it translates an easy-to-read /
+easy-to-write structured text format into HTML. Markdown's text format
+is most similar to that of plain text email, and supports features such
+as headers, *emphasis*, code blocks, blockquotes, and links.
+
+Markdown's syntax is designed not as a generic markup language, but
+specifically to serve as a front-end to (X)HTML. You can use span-level
+HTML tags anywhere in a Markdown document, and you can use block level
+HTML tags (like 
     and  as well).
+
+For more information about Markdown's syntax, see:
+
+
+
+
+Bugs
+----
+
+To file bug reports please send email to:
+
+
+
+Please include with your report: (1) the example input; (2) the output you
+expected; (3) the output Markdown actually produced.

+
+PHP Markdown Extra
+==================
+
+Description
+-----------
+
+This is a PHP port of the original Markdown formatter written in Perl 
+by John Gruber. This special "Extra" version of PHP Markdown features 
+further enhancements to the syntax for making additional constructs 
+such as tables and definition list.
+
+Markdown is a text-to-HTML filter; it translates an easy-to-read /
+easy-to-write structured text format into HTML. Markdown's text format
+is most similar to that of plain text email, and supports features such
+as headers, *emphasis*, code blocks, blockquotes, and links.
+
+Markdown's syntax is designed not as a generic markup language, but
+specifically to serve as a front-end to (X)HTML. You can use span-level
+HTML tags anywhere in a Markdown document, and you can use block level
+HTML tags (like 
     and  as well).
+
+For more information about Markdown's syntax, see:
+
+
+

+Bugs

+
+Please include with your report: (1) the example input; (2) the output you
+expected; (3) the output Markdown actually produced.

    Not sure how to find a feed?
    Try simply putting the url of a webpage in the input box 
    (e.g. http://twitter.com/yongfook) — it works 90% of the time!

    Hello there!
    Looks like it's your first time here.  Why not start by adding some feeds?
    
+
+
+

    Greetings!
    This page shows the last 5 public items in your lifestream.

    Not sure how to find a feed?
    Try simply putting the url of a webpage in the input box 
    (e.g. http://twitter.com/yongfook) — it works 90% of the time!

+* teh blog ar (not) dead *
+==========================
+Version 1.0 (tested with Sweetcron 1.08e)
+
+Thanks for downloading this Sweetcron theme! We know your blog posts are important to you. We also know you're probably an active internet geek much like we are. In the world of Sweetcron, this doesn't fair well for your blog posts.
+
+Never fear - teh blog ar (not) dead will give your blog posts the spotlight they deserve!
+
+Features
+--------
+* Dedicated area for blog items
+* Expandable profile section
+* Activity items link directly to original source
+* Clean customizable single column layout
+
+NOTE
+----
+This theme was created pre-1.08c, when there was no easy way to make custom queries and isolate blog items from the rest. Version 1.08e SHOULD provide an adequate solution to this, making this theme's approach somewhat outdated (we know, our timing is impeccable).
+
+Download the latest version of Sweetcron:
+http://code.google.com/p/sweetcron/downloads/list 
+
+To customize this theme:
+========================
+
+1. Unpackage the ZIP file.
+2. Edit the following files/areas:
+
+_header.php
+-----------
+* RSS links (line 71)
+* Profile picture (line 85)
+* Profile bio (line 90)
+* Contact links (starts line 97)
+
+_acivity_feed.php
+-----------------
+* Twitter profile picture (line 91) (you might want to download a Twitter plugin that can pull this dynamically instead)
+
+Images
+------
+* i/profile-blank.png
+* i/twitter-blank.png
+
+To activate this theme:
+=======================
+
+1. Copy the entire theme folder into your web server's /system/application/views/themes/ directory.
+2. Login to your Sweetcron admin, click Options, and select 'Teh Blog Ar (not) Dead' from the Theme dropdown menu.
+3. Celebrate your new-found awesomeness.
+
+Support
+=======
+
+Unfortunately, at the moment we are unable to provide any type of support for this theme. teh blog ar (not) dead is provided *as is* and we cannot guarantee its compatibility with future versions of Sweetcron.
+
+All that mean stuff being said, we will do our best to listen to your feedback, comments, flames and hugs. Please leave your thoughts on our Sweetcron discussion group thread: http://mawsh.com/labs/tehblogarnotdead/discuss/.
+

+load->plugin('captcha');
+
+Once loaded you can generate a captcha like this:
+	
+	$vals = array(
+					'word'		 => 'Random word',
+					'img_path'	 => './captcha/',
+					'img_url'	 => 'http://www.your-site.com/captcha/',
+					'font_path'	 => './system/texb.ttf',
+					'img_width'	 => '150',
+					'img_height' => 30,
+					'expiration' => 7200
+				);
+	
+	$cap = create_captcha($vals);
+	echo $cap['image'];
+	
+
+NOTES:
+	
+	The captcha function requires the GD image library.
+	
+	Only the img_path and img_url are required.
+	
+	If a "word" is not supplied, the function will generate a random
+	ASCII string.  You might put together your own word library that
+	you can draw randomly from.
+	
+	If you do not specify a path to a TRUE TYPE font, the native ugly GD
+	font will be used.
+	
+	The "captcha" folder must be writable (666, or 777)
+	
+	The "expiration" (in seconds) signifies how long an image will
+	remain in the captcha folder before it will be deleted.  The default
+	is two hours.
+
+RETURNED DATA
+
+The create_captcha() function returns an associative array with this data:
+
+  [array]
+  (
+	'image' => IMAGE TAG
+	'time'	=> TIMESTAMP (in microtime)
+	'word'	=> CAPTCHA WORD
+  )
+
+The "image" is the actual image tag:
+
+
+The "time" is the micro timestamp used as the image name without the file
+extension.  It will be a number like this:  1139612155.3422
+
+The "word" is the word that appears in the captcha image, which if not
+supplied to the function, will be a random string.
+
+
+ADDING A DATABASE
+
+In order for the captcha function to prevent someone from posting, you will need
+to add the information returned from create_captcha() function to your database.
+Then, when the data from the form is submitted by the user you will need to verify
+that the data exists in the database and has not expired.
+
+Here is a table prototype:
+
+	CREATE TABLE captcha (
+	 captcha_id bigint(13) unsigned NOT NULL auto_increment,
+	 captcha_time int(10) unsigned NOT NULL,
+	 ip_address varchar(16) default '0' NOT NULL,
+	 word varchar(20) NOT NULL,
+	 PRIMARY KEY (captcha_id),
+	 KEY (word)
+	)
+
+
+Here is an example of usage with a DB.
+
+On the page where the captcha will be shown you'll have something like this:
+
+	$this->load->plugin('captcha');
+	$vals = array(
+					'img_path'	 => './captcha/',
+					'img_url'	 => 'http://www.your-site.com/captcha/'
+				);
+	
+	$cap = create_captcha($vals);
+
+	$data = array(
+					'captcha_id'	=> '',
+					'captcha_time'	=> $cap['time'],
+					'ip_address'	=> $this->input->ip_address(),
+					'word'			=> $cap['word']
+				);
+
+	$query = $this->db->insert_string('captcha', $data);
+	$this->db->query($query);
+		
+	echo 'Submit the word you see below:';
+	echo $cap['image'];
+	echo '';
+
+
+Then, on the page that accepts the submission you'll have something like this:
+
+	// First, delete old captchas
+	$expiration = time()-7200; // Two hour limit
+	$DB->query("DELETE FROM captcha WHERE captcha_time < ".$expiration);		
+
+	// Then see if a captcha exists:
+	$sql = "SELECT COUNT(*) AS count FROM captcha WHERE word = ? AND ip_address = ? AND date > ?";
+	$binds = array($_POST['captcha'], $this->input->ip_address(), $expiration);
+	$query = $this->db->query($sql, $binds);
+	$row = $query->row();
+
+	if ($row->count == 0)
+	{
+		echo "You must submit the word that appears in the image";
+	}

+	If you do not specify a path to a TRUE TYPE font, the native ugly GD
+	font will be used.
+	
+	The "captcha" folder must be writable (666, or 777)
+	
+	The "expiration" (in seconds) signifies how long an image will
+	remain in the captcha folder before it will be deleted.  The default
+	is two hours.
+
+RETURNED DATA
+
+The create_captcha() function returns an associative array with this data:
+
+  [array]
+  (
+	'image' => IMAGE TAG
+	'time'	=> TIMESTAMP (in microtime)
+	'word'	=> CAPTCHA WORD
+  )
+
+The "image" is the actual image tag:
+
+
+The "time" is the micro timestamp used as the image name without the file
+extension.  It will be a number like this:  1139612155.3422
+
+The "word" is the word that appears in the captcha image, which if not
+supplied to the function, will be a random string.
+
+
+ADDING A DATABASE
+
+In order for the captcha function to prevent someone from posting, you will need
+to add the information returned from create_captcha() function to your database.
+Then, when the data from the form is submitted by the user you will need to verify
+that the data exists in the database and has not expired.
+
+Here is a table prototype:
+
+	CREATE TABLE captcha (
+	 captcha_id bigint(13) unsigned NOT NULL auto_increment,
+	 captcha_time int(10) unsigned NOT NULL,
+	 ip_address varchar(16) default '0' NOT NULL,
+	 word varchar(20) NOT NULL,
+	 PRIMARY KEY (captcha_id),
+	 KEY (word)
+	)
+
+
+Here is an example of usage with a DB.
+
+On the page where the captcha will be shown you'll have something like this:
+
+	$this->load->plugin('captcha');
+	$vals = array(
+					'img_path'	 => './captcha/',
+					'img_url'	 => 'http://www.your-site.com/captcha/'
+				);
+	
+	$cap = create_captcha($vals);
+
+	$data = array(
+					'captcha_id'	=> '',
+					'captcha_time'	=> $cap['time'],
+					'ip_address'	=> $this->input->ip_address(),
+					'word'			=> $cap['word']
+				);
+
+	$query = $this->db->insert_string('captcha', $data);
+	$this->db->query($query);
+		
+	echo 'Submit the word you see below:';
+	echo $cap['image'];
+	echo '';
+
+
+Then, on the page that accepts the submission you'll have something like this:
+
+	// First, delete old captchas
+	$expiration = time()-7200; // Two hour limit
+	$DB->query("DELETE FROM captcha WHERE captcha_time < ".$expiration);		
+
+	// Then see if a captcha exists:
+	$sql = "SELECT COUNT(*) AS count FROM captcha WHERE word = ? AND ip_address = ? AND date > ?";
+	$binds = array($_POST['captcha'], $this->input->ip_address(), $expiration);
+	$query = $this->db->query($sql, $binds);
+	$row = $query->row();
+
+	if ($row->count == 0)
+	{
+		echo "You must submit the word that appears in the image";
+	}
