On MacOS, I guess it should be echo -e instead of echo to make \t work correctly

I use MacOS too and tend to run shell script files using sh x.sh. That instead shows -e in output. You are right when using bash (bash x.sh or command directly on terminal). I'm not sure which way is more commonly used.

Note: Why sleep 1?

• I saw sometimes elm-make compiled more than 1 module without waiting. Not sure how long we should wait, but 1s may be enough.
• I don't know common way to sleep less than 1s. (I'm not very good at shell script)

If you find a better way, don't forget to confirm it really compiles exactly 1 module.
