#     directly on its contribution.
#
#     2. Grant of Rights

#     including the license conditions and limitations in section 3,
#     each contributor grants you a non-exclusive, worldwide,
#     royalty-free copyright license to reproduce its contribution,
#     prepare derivative works of its contribution, and distribute
#     its contribution or any derivative works that you create.
#     (B) Patent Grant- Subject to the terms of this license,
#     including the license conditions and limitations in section 3,
#     each contributor grants you a non-exclusive, worldwide,

#     (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.
#     (C) If you distribute any portion of the software, you must
#     retain all copyright, patent, trademark, and attribution
#     notices that are present in the software.
#     (D) If you distribute any portion of the software in source
#     code form, you may do so only under this license by including a
#     complete copy of this license with your distribution. If you
#     distribute any portion of the software in compiled or object
#     code form, you may only do so under a license that complies
#     with this license.
#     (E) The software is licensed "as-is." You bear the risk of
#     using it. The contributors give no express warranties,
