org-crypt Error: org-crypt-use-before-save-magic

[Ian Barton <lists@manor-farm.org>]

I am investigating using org-crypt in some of my files. In my .emacs I have:

#+BEGIN_SRC emacs-lisp
(require 'org-crypt)
(org-crypt-use-before-save-magic)

(setq org-tags-exclude-from-inheritance (quote ("crypt")))
; GPG key to use for encryption
(setq org-crypt-key "MyKey")
#+END_SRC

When I start Emacs I get:

Warning (initialization): An error occurred while loading 
`/home/ian/.emacs':

Symbol's function definition is void: org-crypt-use-before-save-magic

To ensure normal operation, you should investigate and remove the
cause of the error in your initialization file.  Start Emacs with
the `--debug-init' option to view a complete error backtrace.

The corresponding backtrace is:

Debugger entered--Lisp error: (void-function 
org-crypt-use-before-save-magic)

I am using a recent git checkout.

I notice that org-crypt isn't documented in the manual and there is an 
old message from Carsten asking for someone to document it. If I can get 
it working I'll promise to document it:) Also I'll write something about 
using ssh agent with org an Emacs, a topic that has cuased me some head 
scratching recently.
