io:format and output

Format strings

io:format reads a format string and a list of terms. The tilde codes are: ~p for any term readably, ~s for strings, ~w for words, ~n for a newline, and ~f for raw text.

1> io:format("Hello ~p!~n", ["world"]).

Hello world!

ok

~s prints a string, ~w prints a word with quotes, ~f prints the binary as-is.
