While this makes sure we respect 7// every license restriction, it may not be entirely correct. 8// 9// e.g. GPL in an MIT project might only apply to the contrib/ directory. 10// 11// Please consider splitting the single license below into multiple licenses, 12// taking care not to lose any license_kind information, and overriding the 13// default license using the 'licenses: [...]' property on targets as needed. 14// 15// For unused files, consider creating a 'filegroup' with "//visibility:private" 16// to attach the license to, and including a comment whether the files may be 17// used in the current project. 18// 19// large-scale-change included anything that looked like it might be a license 20// text as a license_text. e.g. LICENSE, NOTICE, COPYING etc. 21// 22// Please consider
