Not all systems use the same char sequence for line breaks. In 
particular, Microsoft Windows uses "\r\n".

You can use 
[`std.ascii.newline`](https://dlang.org/phobos/std_ascii.html#newline) to write
platform-independent code. Functions like `std.stdio.writeln` that write a
newline at the end of the message will also do the right thing.
