Commit Messages

<Summary of change, in present tense>
<blank line>
<Description>

The description is optional. In present tense: instead of "fixed bug", it should be "fix bug".

More details at http://tbaggery.com/2008/04/19/a-note-about-git-commit-messages.html

Some other rules to follow (although optional for now): summary 50 chars or less, manually insert line breaks at 72 chars.

TODO: standardise on modules (a.k.a. components), and include in commit message style
