T-License
T-License is the license used by T-Engine Forum for distributing T-Kernel source code. License fee is free if products are developed according to T-License conditions. According to the first version of T-License, changing or modifying the T-Kernel source code can only be done by certain parties like A-level members of the T-Engine Forum and these parties must notify and register their changes with the T-Engine Forum.
But this restriction has been mostly lifted in the current version of T-License, called T-License 2.0 which is in force since May, 2011.
