I followed the steps outlined in the worg tutorial about using git to keep
track of changes to one's own org data tree.

I still don't understand: how does one go about recovering an earlier
version of a file that has been corrupted?  Is there a good tutorial on this
aspect of using git?  I really like this idea, especially since I have
several times bodged an org-mode file by foolishly doing this:
   C-x C-T *

and making other importune mistakes.

Thank you,
