I wrote a tool to generate my comments. It lets me enter as many lines as I want. It will use the actual line drawing ascii, if the editor allows, and lets me select centered, double lined outline, what the leading comment string should be, etc. I also have the option to start one line with my comment start character, type as many lines as I like, highlight from the end up to somewhere on the first line of text, hit a key, and it all goes into a nice blocked comment. You can type a comment, hit a key and the line is automatically boxed for you. Of course you need to be using a full font that's monospaced, like Consolas.
