8// Added automatically by a large-scale-change that took the approach of
9// 'apply every license found to every target'. While this makes sure we respect
10// every license restriction, it may not be entirely correct.
11//
12// e.g. GPL in an MIT project might only apply to the contrib/ directory.
13//
14// Please consider splitting the single license below into multiple licenses,
15// taking care not to lose any license_kind information, and overriding the
16// default license using the 'licenses: [...]' property on targets as needed.
17//
18// For unused files, consider creating a 'fileGroup' with "//visibility:private"
19// to attach the license to, and including a comment whether the files may be
20// used in the current project.
21//
22// large-scale-change filtered out the below license kinds as false-positives:
23//   SPDX-license-identifier-GPL
24//   SPDX-license-identifier-GPL-2.0
25//   SPDX-license-identifier-LGPL
26// See: http://go/android-license-faq
