Writing a commit message

A good commit message should have two basic parts; a subject, and a description (if required). The subject is always on the first line (and only the first line), and the description is always separated from the subject with a blank line.

<Subject: brief one-liner describing your changes>

<Description: if more detail is needed, then skip a line
and put it in the description. However, if you don't think
you need it, then a one-line commit message is OK>

Additionally:

• The subject line should be no longer than 72 characters. Lines in the description should be no longer than 80 characters.
• Always use imperative mood for commit messages, as if you are commanding the code to change its behaviour; instead of saying "I added a new feature" and "I fixed the bug", say "Add a new feature" and "Fix the bug".
• Make sure your commit message contains an accurate summary of your changes (for example, "Made some improvements" is a bad commit message). If you're finding it difficult to summarise your changes in one commit message, then perhaps you should consider breaking the change up into multiple commits.
