Recovering Data from Auto-Saves
-------------------------------

   If you want to use the contents of an auto-save file to recover from
a loss of data, use the command `M-x recover-file RET FILE RET'.  Emacs
visits FILE and then (after your confirmation) restores the contents
from the auto-save file `#FILE#'.  You can then save the file with `C-x
C-s' to put the recovered text into FILE itself.  For example, to
recover file `foo.c' from its auto-save file `#foo.c#', do:

     M-x recover-file RET foo.c RET
     C-x C-s

   Before asking for confirmation, `M-x recover-file' displays a
directory listing describing the specified file and the auto-save file,
so you can compare their sizes and dates.  If the auto-save file is
older, `M-x recover-file' does not offer to read it.

   Auto-saving is disabled by `M-x recover-file' because using this
command implies that the auto-save file contains valuable data from a
past session.  If you save the data in the visited file and then go on
to make new changes, turn auto-saving back on with `M-x auto-save-mode'.
