-* +----------------------------- IMPORTANT ------------------------------+
-* | Usage of this class compared to native php extensions such as |
-* | mailparse or imap, is slow and may be feature deficient. If available|
-* | you are STRONGLY recommended to use the php extensions. |

-*
-* Mime Decoding class
-*
-* This class will parse a raw mime email and return
-* the structure. Returned structure is similar to
-* that returned by imap_fetchstructure().
-*
-* USAGE: (assume $input is your raw email)
-*
-* $decode = new Mail_mimeDecode($input, "\r\n");
-* $structure = $decode->decode();
-* print_r($structure);
-*
-* Or statically:
-*
-* $params['input'] = $input;
-* $structure = Mail_mimeDecode::decode($params);
-* print_r($structure);
-*
-* TODO:
-* - Implement further content types, eg. multipart/parallel,
-* perhaps even message/partial.
