-   * Anyone can add text to this document.  Do not spend very much time

-   * The maintainer will go through Misc/NEWS periodically and add

-   or esoteric to include.  If such a change is added to the text,
-   I'll just remove it.  (This is another reason you shouldn't spend
-   too much time on writing your addition.)
-
-   * If you want to draw your new text to the attention of the
-   maintainer, add 'XXX' to the beginning of the paragraph or
-   section.
-
-   * It's OK to just add a fragmentary note about a change.  For
-   example: "XXX Describe the transmogrify() function added to the
-   socket module."  The maintainer will research the change and
-   write the necessary text.

-   * You can comment out your additions if you like, but it's not
-   necessary (especially when a final release is some months away).
