5 // HorizontalRule is used by specifying the length of the rule as a
6 // c'tor argument, and then by specifying the character to be repeated
7 // as an argument to the function-call operator (e.g.):
8 //
9 // HorizontalRule r{30}; // Repeats a character 30 times
10 // std::cout << r('=') << '\n'
11 // << r('-') << '\n';
