How to write a good commit comment.

When using version control one common problem area are the dreaded commit comments. Most teams and individuals seems to gravitate towards simply not using them, wich is really sad. My best advice to remedy this situation is really really simple. Don't write your commit comment after you done your changes, write it *before* you start working, that way you already have it done when you're done, and you get the added benefit of clearly articulating what you're currently working on. As Stephen Covey puts it "Begin with the end in mind.", it's true for highly successfull people, it ought to be true for highly successfull programmers.
