 * We can probably delete this method now. I believe that after Jave 1.5, getenv
 * was restored to the API.
 * WARNING: This doesn't work. What seems to happen is that
 * echo runs, and prints out the rest of the string, rather than
 * taking the entire string as a command and arguments. Escaping
 * the quotes doesn't help.
 * Get the value of an environment varialbe. Similar to the C getenv command.
