This is a documentation comment to explain the printAnotherMessage function below.
Accepting an Io.Writer instance is a handy way to write reusable code.
pub fn printAnotherMessage(writer: *Io.Writer) Io.Writer.Error!void
pub fn printAnotherMessage(writer: *Io.Writer) Io.Writer.Error!void {
try writer.print("Run `zig build test` to run the tests.\n", .{});
}
