41	* \| Usage of this class compared to native php extensions such as \|

46	* Mime Decoding class
47	*
48	* This class will parse a raw mime email and return
49	* the structure. Returned structure is similar to
50	* that returned by imap_fetchstructure().
51	*
52	* USAGE: (assume $input is your raw email)
53	*
54	* $decode = new Mail_mimeDecode($input, "\r\n");
55	* $structure = $decode->decode();
56	* print_r($structure);
57	*
58	* Or statically:
59	*
60	* $params['input'] = $input;
61	* $structure = Mail_mimeDecode::decode($params);
62	* print_r($structure);
63	*
64	* TODO:
65	* o Implement multipart/appledouble
66	* o UTF8: ???
67
68	> 4. We have also found a solution for decoding the UTF-8
69	> headers. Therefore I made the following function:
70	>
71	> function decode_utf8($txt) {
72	> $trans=array("?#8216;"=>"探","撤"=>"短","?"=>"?#8226;","徹"
73	=>"?#8250;");
74	> $txt=strtr($txt,$trans);
75	> return(utf8_decode($txt));
76	> }
77	>
78	> And I have inserted the following line to the class:
79	>
80	> if (strtolower($charset)=="utf-8") $text=decode_utf8($text);
81	>
82	> ... before the following one in the "_decodeHeader" function:
83	>
84	> $input = str_replace($encoded, $text, $input);
85	>
86	> This way from now on it can easily decode the UTF-8 headers too.
