3	* File : tnefparser.php
4	* Project : Z-Push
5	* Descr : This is tnef implementation for z-push.
6	* It is based on Zarafa's tnef implementation.
7	* This class does only simple reading of a
8	* tnef stream. Most importantly, we currently
9	* only support properties within the message itself,
10	* and do not support recipient tables and
11	* attachment properties within the TNEF data.
12	* This class will accept TNEF streams with data about
13	* recipients and attachments, but the information
14	* will be ignored.
