I came across some old PCB code for making elements, circa 2004, in my archives.
I'd like to know who wrote it as there is no attribution or licenses
information.

Package consists of library.c library.h and a 'C' file for each
produced element, which includes library.h.

library.c starts off:

#include <stdio.h>
#include <math.h>
#include <stdlib.h>
#include "library.h"

#define PIN     0
#define PAD     1
#define BORE    2

#define MILS    1
#define MM      2

#define FACTOR 39.37

static int      l_conversion = MILS;    // Conversion factor, start in mils
static int      l_pad_width = 60;       // Pad width, in mils
...

An example, diode.c, looks like:

#define DIMC 6.8
#define DIMZ DIMC + DIMY

#define DIMY 2.0
#define DIMX 3.0

#define WIDTH 7.0
#define HEIGHT 9.5

void make_element(void)
{
       set_mm();

       header("Big Diode", "D1", "diode", 0, 0, RIGHT);

       set_pad(DIMZ - DIMC, DIMX, .2, DIMX + .2);
       up(DIMC / 2.0);
       pads_down(DIMC, 2, 1, -1);

       up(DIMC / 2.0 + HEIGHT / 2.0);
       left(WIDTH / 2.0);

       pen_on();
       right(WIDTH);
       down(HEIGHT);
       left(WIDTH);
       up(HEIGHT + 1);
       right(WIDTH);
       down(1);

}

Anyone recognize this package?

I want to update it, and want to know who to attribute the work to.
