24 | ;;; If you put a time stamp template anywhere in the first 8 lines of a file, | |
25 | ;;; it can be updated every time you save the file. See the top of | |
26 | ;;; time-stamp.el for a sample. The template looks like one of the following: | |
27 | ;;; Time-stamp: <> | |
08cb6a9f | 28 | ;;; Time-stamp: " " |
9565745a | 29 | ;;; The time stamp is written between the brackets or quotes, resulting in |
b1defad2 | 30 | ;;; Time-stamp: <95/01/18 10:20:51 gildea> |
c7c4ddd4 | 31 | ;;; Here is an example that puts the file name and time stamp in the binary: |
9565745a RS |
32 | ;;; static char *time_stamp = "sdmain.c Time-stamp: <>"; |
33 | ||
b1defad2 RS |
34 | ;;; To activate automatic time stamping in GNU Emacs 19, add this code |
35 | ;;; to your .emacs file: | |
36 | ;;; (add-hook 'write-file-hooks 'time-stamp) | |
