-;;; Commentary:
-
-; DESCRIPTION:
-; ------------
-; This program can be used to monitor running time performance of Emacs Lisp
-; functions. It takes a list of functions and report the real time spent
-; inside these functions. It runs a process with a separate timer program.
-; Caveat: the C code included with this package requires BSD-compatible
-; time-of-day functions. If you're running an AT&T version prior to SVr4,
-; you may have difficulty getting it to work. Your X library may supply
-; the required routines if the standard C library does not.
-
-; HOW TO USE:
-; -----------
-; Set the variable profile-functions-list to the list of functions
-; (as symbols) You want to profile. Call M-x profile-functions to set
-; this list on and start using your program. Note that profile-functions
-; MUST be called AFTER all the functions in profile-functions-list have
-; been loaded !! (This call modifies the code of the profiled functions.
-; Hence if you reload these functions, you need to call profile-functions
-; again! ).
-; To display the results do M-x profile-results . For example:
-;-------------------------------------------------------------------
-; (setq profile-functions-list '(sokoban-set-mode-line sokoban-load-game
-; sokoban-move-vertical sokoban-move))
-; (load "sokoban")
-; M-x profile-functions
-; ... I play the sokoban game ..........
-; M-x profile-results
-;
-; Function Time (Seconds.Useconds)
-; ======== =======================
-; sokoban-move 0.539088
-; sokoban-move-vertical 0.410130
-; sokoban-load-game 0.453235
-; sokoban-set-mode-line 1.949203
-;-----------------------------------------------------
-; To clear all the settings to profile use profile-finish.
-; To set one function at a time (instead of or in addition to setting the
-; above list and M-x profile-functions ) use M-x profile-a-function .
-
-; HOW TO INSTALL:
-; ---------------
-; First you need to compile and install the following C program in your
-; path under the name "emacs-timer" (or set the variable
-; profile-timer-program to whatever name you picked).
-;
-;/**
-; ** To be run as an emacs process. Input string that starts with:
-; ** 'z' -- resets the watch (to zero).
-; ** 'p' -- return time (on stdout) as string with format <sec>.<micro-sec>
-; ** 'q' -- exit.
-; **
-; ** abstraction : a stopwatch
-; ** operations: reset_watch, get_time
-; */
-;#include <strings.h>
-;#include <sys/time.h>
-;#include <stdio.h>
-;static struct timeval TV1,TV2;
-;static struct timezone *tzp = (struct timezone *) NULL; /* no need timezone */
-;static int watch_not_started = 1 ; /* flag */
-;static char time_string[30];
-;
-;int reset_watch() /* this call resets the stopwatch to zero */
-;{
-; gettimeofday(&TV1, tzp) ;
-; watch_not_started = 0;
-;}
-;
-;char *get_time()
-; /* this call returns the time since the last reset_watch() call. The time
-; is returned as a string with the format <seconds>.<micro-seconds>
-; If reset_watch() was not called yet, returns NULL */
-;{
-; char *result = time_string ;
-; int i;
-; if (watch_not_started) return((char *) 0); /* call reset_watch first ! */
-; gettimeofday(&TV2, tzp);
-; if ( TV1.tv_usec > TV2.tv_usec )
-; {
-; TV2.tv_usec += 1000000;
-; TV2.tv_sec--;
-; }
-; sprintf(result,"%lu.%6lu",
-; TV2.tv_sec - TV1.tv_sec, TV2.tv_usec - TV1.tv_usec);
-; for (result = index(result,'.') + 1 ; *result == ' ' ; result++ )
-; *result = '0';
-; return(time_string);
-;}
-;
-;void main()
-;{
-; char inp[10];
-; while (1)
-; {
-; gets(inp);
-; switch (inp[0])
-; {
-; case 'z': reset_watch();
-; break;
-; case 'p': puts(get_time());
-; break;
-; case 'q': exit(0);
