CBA: Community Based Addons for Arma 3
Current version: 3.7.1
What does the name Community Base Addons mean? It is a system that:
  • Offers a range of features for addon-makers and mission designers.
  • Aims to have community wide acceptance and to be used as much as possible by community addons to maintain compatibility.
  • The community is very much encouraged to request or submit functionality.
  • The most obvious example would be to submit functions to be included in the CBA function library.
Full documentation is available at GitHub[]

Licensed Under GPLv2
Any addon which calls CBA-defined functions need not be licensed under the GPLv2
or released under a free software license. Only if you are directly including CBA code
in your addon's binarized PBO or redistributing a modified version of CBA itself would
your work be considered derivative and therefore be legally required to be released under
the terms of the GPL. (And there's no reason to ever do either of these.)

I think any server's allowed to use this mod copyright-wise FragZ.

Are we allowed to use this addon inside a non monetized pianosa life server? With proper credits of course...
We use a C# launcher to sync mods with players so the cba addons would be inside a mod folder that is common to us, but not reuploaded to steam. Let me know!

My launcher says this addon is corrupt. I don't exactly see how.
