Attention base developers: ChangeLog entries

A note for developers working on the MacPorts base code: - It is your responsibility to keep the ChangeLog up to date with substantive changes in base. - Not only does this tell users what has changed, but it also helps us internally track what has changed. - Changes that haven't been released should be put in the "unreleased" section of the ChangeLog file. These will be rolled into the proper release by the "releaser", who is a bit like the "decider" ;) - Please annotate ChangeLog entries with your name and the revision number when possible. Thanks! James
