class RedFlashHandler(logging.Handler):
""" Logging handler for redflash primarily intended for making it easy to send SMS alerts via RedFlash. Arguments to supply either
via dictConfig or directly are:
* host
* apikey
* notify_groups: list of group names to notify (if any)
* notify_contacts: list of contact names to notify (if any)
* fail_silently: default True, swallow errors e.g. if invalid or disabled recipient
* max_len: If None or 0 messages are sent 'as-is', otherwise the message is truncated to the stated length prior to sending. Prevent accidentally sending a large message as a multi-part SMS! Default 160.
* prefix: If set, this is prefixed to all messages going through this logger.
Group and contact names are the slugs as defined in the Redflash records.
