|
# 1. Definitions
|
|
# The terms "reproduce," "reproduction," "derivative works," and
|
|
# "distribution" have the same meaning here as under U.S.
|
|
# copyright law. A "contribution" is the original software, or
|
|
# any additions or changes to the software.
|
|
# A "contributor" is any person or entity that distributes its
|
|
# contribution under this license.
|
|
# "Licensed patents" are a contributor's patent claims that read
|
|
# directly on its contribution.
|
|
#
|
|
# 2. Grant of Rights
|
|
# (A) Copyright 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,
|
|
# 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,

|
# 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.
|
|
# (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,
