-This directory contains files that are necessary or at least useful

-
-noutline.el
-
-   Greg Chernov's port of the overlay-based implementation of
-   outline-mode.  This is required, and until XEmacs uses this (or
-   another port), you need to install it with Org-mode.  The "Installation"
-   section in the Manual covers also the installation of  this package.
-
-ps-print-invisible.el
-
-   Greg Chernovs modification to ps-print, to honor invisible text
-   properties during printing.  This file is not required for running
-   Org-mode, but it is useful when trying to print partial trees.
