Usage:
	makeplthead FSCL X0 Y0 X1 Y1
where FSCL is a font scaling factor (ignored); (X0, Y0) is the lower left
corner of the bounding box;  and (X1, Y1) is the upper right corner of the
bounding box.  Note that the units of X0, Y0, X1, and Y1 are *inches*.

The intended use of this program is within the `lwcat' script, in which the
variable WDEF contains the five command-line arguments in the order given
above.  Thus, from `lwcat', this program is invoked as:
	makeplthead $WDEF
*/

#include <stdio.h>
#include <time.h>

/* If fewer than 5 arguments are supplied, the following default values are
   assumed. These are implied by the WDEF generated by lwplt without -size. */
#define DEFX0 0.775
#define	DEFY0 3.350
#define DEFX1 7.975
#define	DEFY1 9.350

main(argc, argv)
int argc;
char **argv;
{
    double x0 = DEFX0, y0 = DEFY0, x1 = DEFX1, y1 = DEFY1, atof();
    int llx, lly, urx, ury;
    time_t now;

    if (argc > 5) {
	x0 = atof(argv[2]);
	y0 = atof(argv[3]);
	x1 = atof(argv[4]);
	y1 = atof(argv[5]);
    }
    llx = (int)(x0 * 72.0);
    lly = (int)(y0 * 72.0);
    urx = (int)(x1 * 72.0);
    ury = (int)(y1 * 72.0);

    printf("%%!PS-Adobe-3.0\n");
    printf("%%%%BoundingBox: %d %d %d %d\n", llx, lly, urx, ury);
    printf("%%%%Title: (plt/lwcat output)\n");
    (void)time(&now);
    printf("%%%%CreationDate: %s", ctime(&now));
