Carsten Dominik a3f3efe82d Speed-up multiple calls to `org-diary'.
Patch by Matt Lundin

This is the Emacs Org project, an emacs subsystem for organizing your life

The homepage of Org is at http://orgmode.org

This distribution contains:

README
    This file.

README_DIST
    The README file for the distribution (zip and tar files)

README_GIT
    Information about the git repository and how to contribute
    to Org-mode development. 

lisp/
    Directory with all the Emacs Lisp files that make up Org.

doc/
    The documentation files.  org.texi is the source of the
    documentation, org.html and org.pdf are formatted versions of it.

xemacs/
    The xemacs directory contains special code for XEmacs users, in
    particular a port of the GNU Emacs outline.el to XEmacs.  Org-mode
    does not work under XEmacs without this file installed.  It did
    until version 4.37, but no longer.

contrib/
    A directory with third-party additions for Org.  Some really cool
    stuff is in there.

ORGWEBPAGE/
    Directory with the source files for the orgmode.org web page.
    
ChangeLog
    The standard ChangeLog file.

Makefile
    The makefile to compile and install Org, and also for maintenance
    tasks.

request-assign-future.txt
    The form that contributors have to sign and get processed with the
    FSF before contributed changes can be integrated into the Org
    core.  All files in this distribution except the CONTRIB directory
    have copyright assigned to the FSF.

EXPERIMENTAL
    Experimental code, not necessarily FSF copyright.
