Try to write code with a high pylint score, but also use some
common sense. It is sometimes acceptable to break the rules. e.g.
if you are writing graphics code then the variables x, y and z can
be used for co-ordinates.
Don't disable warnings locally; other developers may find them
useful. We want to avoid pages of warnings though.
You should be able to achieve a pylint score greater than 9 on
new files. However, there may be some exceptions for very small
We appreciate contributions that tidy up existing code. Please
put pylint improvements in a separate commit to other changes.
