ChangeLog files...

I (think) I want a ChangeLog file in my software distributions.

Q: Is a ChangeLog file all that useful, or is there another way to get
that sort of information (say, via a  bkweb interface)?

Assuming a ChangeLog file will be in my software distributions, there
are at least two ways it can be kept up-to-date:

- Generate it from the ChangeSet comments
- Let the developers add the entries and hope that merges go OK

Q: are there any other useful choices?

Q: what is the best way to go here?
