** 

** 2016-09-06 support adding celery to existing project.

- This will add a celeryconfig module and a tasks module.

  see examples in

  ~/projects/wechat-article-saver/wechat_article_saver_daemon/wechat_article_saver_daemon/celeryconfig.py

  ~/projects/wechat-article-saver/wechat_article_saver_daemon/wechat_article_saver_daemon/fetcher.py

- I don't know how to call lein from existing project yet.

  shouldn't be so hard.

** 2016-08-18 integrate tox.

let "make test" use the default python in venv, but allow "make tox" to run

unit tests against defined python in tox.ini.
