[xwiki-devs] Tools/approaches to manage Xwiki custom project publicly

I'm working on a project, which potentially could be useful for more than one customer. Therefore I'm thinking how to manage automated updates for Xwiki content (xar file for partial export) and ../webapps/xwiki (additional jar files and differences/replacements for existing files) folder. On the one hand it should provide easy steps for Linux/web admins, which are not very familiar with Xwiki for upgrading their, on the other hand, it shouldn't be too hard to manage for me also. I assume, it could be some (xwiki?) github project though I wonder, what structure should I have there. To not reinvent the wheel, can you describe what tools/approaches you see as the best? E.g. how you manage content for: https://github.com/xwiki/xwiki-enterprise/tree/master/xwiki-enterprise-ui/s… Thanks! Valdis
