All work inside Qt source tree must follow Qt licensing policy. Additionally to that, I (Bogdan Daniel Vatra ) hereby release all my work, inside Qt source tree, into the public domain.
All sources (outside Qt source tree) which are directly related with applications (e.g. qtandroidplatformplugin (c++, java, etc.), Ministro communication interface) MUST be released under BSD license.
All other additional tools which don't not affect apps licensing (e.g. Ministro Qt installer/provider) MUST be free software. I (Bogdan Daniel Vatra ) released Ministro under GPL v3+ license, but the communication API/protocol is under BSD license, so, ANY application (even if that application is NOT free software) can freely use Ministro services (Ministro != MySQL :) !).
