Translation-oriented CMS/Wiki/HelpPortal systems?

We need to run a help portal for users of our application. We want every page to be accesible in several languages. I want to find a content-management system which would have rich translation features, such as:

• Per-paragraph translation;
• Warnings for translated content that wasn't updated after a change was made to another language;
• Possibility to choose whether to show or hide paragraphs/pages which are not translated;
• Easy and user-friendly switching between languages (e.g. "this page is 开发者_如何学运维accessible in the following other languages: ...").

I found a MediaWiki plugin which allows at least some of the above mentioned. Are there any CMSes with native orientation for translations and multilingual content?

The Daisy CMS has great built-in translation support.

1. Break your content into sections and translate them individually, or whole pages at a time.

2. You can run a report that tells you which documents have translations that are out of sync with the base language, and which documents don't have translations at all. You can then translate inside the app or export for offline translation and import later.

3. You can exclude untranslated pages and paragraphs from the locale-specific navigation automatically.

4. The menu will automatically show the user which languages are available for a specific page.
