Django-cms and Editorial workflows
When you turn on CMS_MODERATION in Django-CMS, you will get three icons next to each page in the page list view. From left to right, these control

whether changes to this page will require moderator approval
whether changes to this page's children will require moderator approval
whether changes to this page's descendents will require moderator approval

When you create or change a page, you will be able to save it, and preview the page or new version of the page on your site, but it will require moderator approval before the page or new version of the page is visible to end users.
I need to implement workflows in my Django-CMS application at work. But form the Django-CMS feature list, we can read:
Editorial workflow
Workflows for publishing and approval.
I tried to search for it and didn't find anything. I've search the Django-CMS documentation (http://docs.django-cms.org/en/latest/index.html) and couldn't find something there either.
Does anyone has a clue about Workflows in Django-CMS (especially for the pages system) ?
