+* Raw mime encoding class
+*
+* What is it?
+* This class enables you to manipulate and build
+* a mime email from the ground up.
+*
+* Why use this instead of mime.php?
+* mime.php is a userfriendly api to this class for
+* people who aren't interested in the internals of
+* mime mail. This class however allows full control
+* over the email.
+*
+* Eg.
+*
+* // Since multipart/mixed has no real body, (the body is
+* // the subpart), we set the body argument to blank.
+*
+* $params['content_type'] = 'multipart/mixed';
+* $email = new Mail_mimePart('', $params);
+*
+* // Here we add a text part to the multipart we have
+* // already. Assume $body contains plain text.
+*
+* $params['content_type'] = 'text/plain';
+* $params['encoding'] = '7bit';
+* $text = $email->addSubPart($body, $params);
+*
+* // Now add an attachment. Assume $attach is
+* the contents of the attachment
+*
+* $params['content_type'] = 'application/zip';
+* $params['encoding'] = 'base64';
+* $params['disposition'] = 'attachment';
+* $params['dfilename'] = 'example.zip';
+* $attach =& $email->addSubPart($body, $params);
+*
+* // Now build the email. Note that the encode
+* // function returns an associative array containing two
+* // elements, body and headers. You will need to add extra
+* // headers, (eg. Mime-Version) before sending.
+*
+* $email = $message->encode();
+* $email['headers'][] = 'Mime-Version: 1.0';
+*
+*
+* Further examples are available at http://www.phpguru.org
+*
+* TODO:
+* - Set encode() to return the $obj->encoded if encode()
+* has already been run. Unless a flag is passed to specifically
+* re-build the message.

+ -------====Website Screenshots configuration - BETA====-------
+
+ If you just want image thumbnails and don't want website screenshots, you can safely leave this as is.
+
+ If you would like to get website screenshots set up, you will need root access to your own server.
+
+ Enable ALLOW_ALL_EXTERNAL_SITES so you can fetch any external web page. This is more secure now that we're using a non-web folder for cache.
+ Enable BLOCK_EXTERNAL_LEECHERS so that your site doesn't generate thumbnails for the whole Internet.
+
+ Instructions to get website screenshots enabled on Ubuntu Linux:
+
+ 1. Install Xvfb with the following command: sudo apt-get install subversion libqt4-webkit libqt4-dev g++ xvfb
+ 2. Go to a directory where you can download some code
+ 3. Check-out the latest version of CutyCapt with the following command: svn co https://cutycapt.svn.sourceforge.net/svnroot/cutycapt
+ 4. Compile CutyCapt by doing: cd cutycapt/CutyCapt
+ 5. qmake
+ 6. make
+ 7. cp CutyCapt /usr/local/bin/
+ 8. Test it by running: xvfb-run --server-args="-screen 0, 1024x768x24" CutyCapt --url="http://markmaunder.com/" --out=test.png
+ 9. If you get a file called test.png with something in it, it probably worked. Now test the script by accessing it as follows:
+ 10. http://yoursite.com/path/to/timthumb.php?src=http://markmaunder.com/&webshot=1
+
+ Notes on performance:
+ The first time a webshot loads, it will take a few seconds.
+ From then on it uses the regular timthumb caching mechanism with the configurable options above
+ and loading will be very fast.
+
+ --ADVANCED USERS ONLY--
+ If you'd like a slight speedup (about 25%) and you know Linux, you can run the following command which will keep Xvfb running in the background.
+ nohup Xvfb :100 -ac -nolisten tcp -screen 0, 1024x768x24 > /dev/null 2>&1 &
+ Then set WEBSHOT_XVFB_RUNNING = true below. This will save your server having to fire off a new Xvfb server and shut it down every time a new shot is generated.
+ You will need to take responsibility for keeping Xvfb running in case it crashes. (It seems pretty stable)
+ You will also need to take responsibility for server security if you're running Xvfb as root.
+
+
+*/
+if(! defined('WEBSHOT_ENABLED') ) define ('WEBSHOT_ENABLED', false); //Beta feature. Adding webshot=1 to your query string will cause the script to return a browser screenshot rather than try to fetch an image.
