void putc(int c)
{
  write(STDOUT, &c, 1);

  if(c == '\n')
    putc('\r');
}

void puts(char *s)
{
  while(*s)
  {
    putc(*s);

    s++;
  }
}

char *help = "cd [directory]    Change directory.\n" \
             "pwd               Display current directory.\n" \
             "> >>< |           Everyone's favourite pipes!\n" \
             "\n(Hint: Everything else is a command.)\n";

-----------------------------------------
puts(help) only displays up until "mand." in the last line.
printf("%s", help) displays it all.

Both call putc(). Thoughts?
