Using an example binary

You can now use the binary as normal. For example, save the following erlang script and call it hello:

#!/usr/bin/env escript
-export([main/1]).
main([]) -> io:format("Hello, World!~n").

Then do the following:

/bin/escript hello or escript hello

$ escript hello
Hello, World!
