+// Overarching principles for Rust lints on Android:
+// The Android build system tries to avoid reporting warnings during the build.
+// Therefore, by default, we upgrade warnings to denials. For some of these
+// lints, an allow exception is setup, using the variables below.
+// There are different default lints depending on the repository location (see
+// DefaultLocalClippyChecks).
+// The lints are split into two categories. The first one contains the built-in
+// lints (https://doc.rust-lang.org/rustc/lints/index.html). The second is
+// specific to Clippy lints (https://rust-lang.github.io/rust-clippy/master/).
+//
+// When developing a module, it is possible to use the `no_lint` property to
+// disable the built-in lints configuration. It is also possible to set
+// `clippy` to false to disable the clippy verification. Expect some
+// questioning during review if you enable one of these options. For external/
+// code, if you need to use them, it is likely a bug. Otherwise, it may be
+// useful to add an exception (that is, move a lint from deny to allow).
