// node.js get keypress

// without this, we would only get streams once enter is pressed
//stdin.setRawMode( true );

// resume stdin in the parent process (node app won't quit all by itself
// unless an error or process.exit() happens)
stdin.resume();
// i don't want binary, do you?

// on any data into stdin
