-;;; Commentary:
-
-;;; If you put a time stamp template anywhere in the first 8 lines of a file,
-;;; it can be updated every time you save the file. See the top of
-;;; time-stamp.el for a sample. The template looks like one of the following:
-;;; Time-stamp: <>
-;;; Time-stamp: " "
-;;; The time stamp is written between the brackets or quotes, resulting in
-;;; Time-stamp: <93/06/18 10:26:51 gildea>
-;;; Here is an example which puts the file name and time stamp in the binary:
-;;; static char *time_stamp = "sdmain.c Time-stamp: <>";
-
-;;; To activate automatic time stamping, add this code to your .emacs file:
-;;;
-;;; (if (not (memq 'time-stamp write-file-hooks))
-;;; (setq write-file-hooks
-;;; (cons 'time-stamp write-file-hooks)))
-;;;
-;;; In Emacs 18 you will also need
-;;; (autoload 'time-stamp "time-stamp" "Update the time stamp in a buffer." t)
-
-;;; Change Log:
-
-;;; Originally based on the 19 Dec 88 version of
-;;; date.el by John Sturdy <mcvax!harlqn.co.uk!jcgs@uunet.uu.net>
-
-;;; Code:
-
-(defvar time-stamp-active t
- "*Non-nil to enable time-stamping of files. See the function time-stamp.")
-
-(defvar time-stamp-format
- '(time-stamp-yy/mm/dd time-stamp-hh:mm:ss user-login-name)
- "*A list of functions to call to generate the time stamp string.
-Each element of the list is called as a function and the results are
-concatenated together separated by spaces. Elements may also be strings,
-which are included verbatim. Spaces are not inserted around literal strings.")
-
-;;; Do not change time-stamp-line-limit, time-stamp-start, or
-;;; time-stamp-end in your .emacs or you will be incompatible
-;;; with other people's files! If you must change them,
-;;; do so only in the local variables section of the file itself.
-
-(defvar time-stamp-line-limit 8 ;Do not change!
- "Number of lines at the beginning of a file that are searched.
-The patterns `time-stamp-start' and `time-stamp-end' must be found on one
-of the first `time-stamp-line-limit' lines of the file for the file to
-be time-stamped by \\[time-stamp].
-
-Do not change `time-stamp-line-limit', `time-stamp-start', or
-`time-stamp-end' for yourself or you will be incompatible
-with other people's files! If you must change them for some application,
-do so in the local variables section of the time-stamped file itself.")
-
-
-(defvar time-stamp-start "Time-stamp:[ \t]+\\\\?[\"<]+" ;Do not change!
- "Regexp after which the time stamp is written by \\[time-stamp].
-See also the variables `time-stamp-end' and `time-stamp-line-limit'.
-

-`time-stamp-end' for yourself or you will be incompatible
-with other people's files! If you must change them for some application,
-do so in the local variables section of the time-stamped file itself.")
-
-
-(defvar time-stamp-end "\\\\?[\">]" ;Do not change!
- "Regexp marking the text after the time stamp.
-\\[time-stamp] deletes the text between the first match of `time-stamp-start'
-and the following match of `time-stamp-end' on the same line,
-then writes the time stamp specified by `time-stamp-format' between them.
