/** 
   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');
