/**
* Name: PHP MimeType Class
*
* Version: 1.0
* Date Released: 10/20/02
*
* Description: This class allows a PHP script to determine the mime type
* a file based on the file extension. This class is handy for PHP versions
* without the benefit of other tools to determine the mime type. The class
* defaults to octet-stream so if the file type is not recognized the user
* is presented with a file download prompt.
*
* NOTES: The mime types for this version are based on Apache 1.3.27
* mime types may change or need to be added in the future, the mime types
* are stored in an array so that an awk or other script can automatically
* generate the code to make the array.
*
* Usage:
*
* First an instance of the mimetype class must be created, then the
* getType method should be called with the filename. It will return
* the mime type, an example follows.
*
* Example:
*
* $mimetype = new mimetype();
* print $mimetype->getType('acrobat.pdf');
*
* Author: Jason Sheets <jsheets@shadonet.com>
*
* License: This script is distributed under the BSD License, you are free
* to use, or modify it however you like. If you find this script useful please
* e-mail me.
