Tips
After the task, a backup file slack-cleaner.<timestamp>.log will be created
in current directory if --log is supplied.
If any API problem occurred, try --rate=<delay-in-seconds> to reduce the API
call rate (which by default is unlimited).
If you see the following warning from urllib3, consider to install missing
packages: pip install --upgrade requests[security] or just upgrade your
Python to 2.7.9.
InsecurePlatformWarning: A true SSLContext object is not available.
This prevents urllib3 from configuring SSL appropriately and may cause certain SSL connections to fail.
For more information, see https://urllib3.readthedocs.org/en/latest/security.html#insecureplatformwarning.
