Well, it's mostly just a POSIX compatible shell with a number of
restrictions and warts. Usually one starts writing scripts like you
would do in any other POSIX shell.  You will quickly see what is not

It is common sense to take a method and try it. If it fails, admit it
frankly and try another. But above all, try something.
