Testing an individual branch/patch combo

make BRANCH=refactoring PATCH=big-todo

This will produce log result in log/$commit-big-todo.log.

Testing all patches

make patches BRANCH=refactoring

For instance, after a commit, for checking if patches still apply or if they need a rework.

Testing all branches

make branches PATCH=big-todo

For instance, after changing a patch to check if it now works better on notqmail.

Branches tested are listed in conf-branch.

Testing all patches and all branches

make everything

Checking every merge request

make brokemaster BRANCH=refactoring

This can be used in a script that automatically runs on merge request. This will return an error only if the current branch broke more patches than what master did already.
