Yahoo-Groups-Archiver, Text Archive Script Copyright 2019 Robert Lancaster and others

YahooGroups-Archiver, a simple python script that allows for all
messages in a public Yahoo Group to be archived.

The Text Archive Script allows you to take the downloaded json documents
and turn them yearly archives of emails sorted into text documents.
Note that the archive-group.py script must be run first.
