+_Tool tasks_ are tasks that can be run from the AuthMe codebase for various purposes, e.g. to generate docs pages or to verify messages tasks. All tool tasks are started from the same runner, the ToolsRunner, located test/tools/ToolsRunner.java. Tip: you can save the run configuration for the ToolsRunner so that you can always easily run a tool task.
