+"""
+This plugin captures logging statements issued during test execution. When an
+error or failure occurs, the captured log messages are attached to the running
+test in the test.capturedLogging attribute, and displayed with the error failure
+output. It is enabled by default but can be turned off with the option
+``--nologcapture``.
+
+You can filter captured logging statements with the ``--logging-filter`` option.
+If set, it specifies which logger(s) will be captured; loggers that do not match
+will be passed. Example: specifying ``--logging-filter=sqlalchemy,myapp``
+will ensure that only statements logged via sqlalchemy.engine, myapp
+or myapp.foo.bar logger will be logged.
+
+You can remove other installed logging handlers with the
+``--logging-clear-handlers`` option.
