|
//
|
||
|
// 2. Grant of Rights
|
||
|
// (A) Copyright Grant- Subject to the terms of this license,

// rights to use any contributor's name, logo, or trademarks.
|
||
|
// (B) If you bring a patent claim against any contributor over

||
|
// patents that you claim are infringed by the software, your
|
||
|
// patent license from such contributor to the software ends
|
||
|
// automatically.
|
