    My comments are as follows:

	* Please provide a ChangeLog for all the changes.

	* New fields in structures need to include documentation.
	  I know that we have not done this in the past, but we are
	  trying to rectify this, so for new patches, we should include
	  a description of the field, and any potential notes on its

	* Any new public methods need to be documented using the 
	  format that can be seen in files like object.c:

		 * method: 
	 	 * arg1: bla bla
	  	 * arg2: bla bla
		 * Description
		 * Returns bla bla
