Input from the standard input

Can you read the standard input stream in an escript?

Yes you can but the obvious script to copy a file:

main([]) ->

copyLoop() ->
    case io:get_chars("", 1) of
C ->
eof ->

This does read and write, but does not halt when it gets to the end of a file that you pipe in.  Hmm.  I'm doing plenty of file reading but I'll open the files in code.
