Odoo is the world's easiest all-in-one management software. It includes hundreds of business apps:
CRM | e-Commerce | Accounting | Inventory | PoS | Project management | MRP | etc.

It seems to me that it was cleared out, but in a way that will let someone think that the document is still there, until he actually tries to open the file... See this url: https://doc.odoo.com/trunk/ and click on any link...
