License

Palanteer uses two different licenses, depending on the components and their inherent constraints:

Instrumentation libraries shall preserve the user's freedom to distribute their program in closed sources
- In this case, the MIT license applies
Improvement on the server tooling side shall benefit to the community
- In this case, the Affero GNU General Public License version 3 or later (AGPL v3+) applies

The big lines are:

./c++, ./python and ./tools are under the MIT license
- these folders contain the instrumentation libraries and helper tools
- This permissive license preserves developers's rights about distributing their software, even if delivered with instrumentation (modified or not).
./server/base is also under the MIT license
- as an exception for server side, the code in this folder, if useful, can be reused in closed source projects.
./server/common, ./server/viewer and ./python/python_scripting are under the AGPL v3+ license
- these parts shall benefit to the community (i.e. sources must be shared if a derivative is distributed) while free to use and modify
- "Affero" version of the GPL was naturally chosen to cover also the case of distribution over network

To remove any ambiguity, each folder contains the associated license and each file has a license header.
