| time-stamp is an interactive compiled Lisp function in `time-stamp'.
| (time-stamp)
| 
| Update the time stamp string(s) in the buffer.
| A template in a file can be automatically updated with a new time stamp
| every time you save the file.  Add this line to your .emacs file:
|     (add-hook 'write-file-hooks 'time-stamp)
| Normally the template must appear in the first 8 lines of a file and
| look like one of the following:
|       Time-stamp: <>
|       Time-stamp: " "
| The time stamp is written between the brackets or quotes:
|       Time-stamp: <1998-02-18 10:20:51 gildea>
| The time stamp is updated only if the variable `time-stamp-active' is
| non-nil.  The format of the time stamp is set by the variable
| `time-stamp-format'.  The variables `time-stamp-line-limit',
| `time-stamp-start', `time-stamp-end', `time-stamp-count', and
| `time-stamp-inserts-lines' control finding the template.

Put a line containing: 

       "Time-stamp: <>"

in one of the first 8 lines of the file you want to time stamp.

With 

(add-hook 'write-file-hooks 'time-stamp) 

in your .emacs the above string gets updated when the file is being
saved.
