You should not compile this script, just run. Remove first line If you want compile it as regular erlang module.

Programming is not an intuitive job, people are not programmed from birth, so there is different ways to be intuitive for different people. For example I see nothing intuitive to mix escript code and code for OTP. If you want to use common library in OTP application and escript, put following line after shebang line: %%! -pa path/to/library
