TODO fix Path math everywhere

#include <stdio.h>

#define PATH_MAX "evil"

int main () {
  return 0;
}

DONE convince the Guix people to use scheme everywhere   scheme

(define (main args)
  ;;the option specification tells getopt-long how
  ;; to parse the command line
  (let* ((option-spec '((version (single-char #\v) (value #f))
                        (help    (single-char #\h) (value #f))
