Requires(post): update-alternatives
Requires(postun):update-alternatives

- version update to 5.5.0
* Use sys._current_frames (rather than threading.enumerate) as base for new thread detection, fixes #130.
* New option --gc-after-test. It calls for a garbage collection after each test and can be used to track down
ResourceWarning``s and cyclic garbage. With ``rv = gc.collect(), ! is output on verbosity level 1 when rv is
non zero (i.e. when cyclic structures have been released), [``*rv*]`` on higher verbosity levels and a detailed
cyclic garbage analysis on verbosity level 4+. For details, see #133.
* Allow the filename for the logging configuration to be specified via the envvar ZOPE_TESTRUNNER_LOG_INI.
If not defined, the configuration continues to be locked for in file log.ini of the current working directory.
Remember the logging configuration file in envvar ZOPE_TESTRUNNER_LOG_INI to allow spawned child processes to
recreate the logging configuration. For details, see #134.

* Do not disable existing loggers during logsupport initialization (#120).
