Although programming books warn of the evils of forgetting to comment, how many of you comment your code, and if so to what extent? Do you have any systematic way of commenting, or arranging your notes on the way a program runs?

I usually comment code after writing it, and I only comment the parts that either I'll forget, or someone else won't understand.

Up till a few weeks ago, I didn't comment code hardly at all. I do now, and generally I just explain what a line (or a few lines) does. [addsig]

Thanks
