Problem Statement

The task is to programmatically obtain the name used to invoke the program. (For example determine whether the user ran "python hello.py", or "python hellocaller.py", a program importing the code from "hello.py".) Sometimes a multiline shebang is necessary in order to provide the script name to a language's internal ARGV. See also Command-line arguments Examples from GitHub.

Let's start with the solution:

#!/usr/bin/env dart

main() {
	var program = new Options().script;
	print("Program: ${program}");
}
