+Directory structure of the audio HAL related code.
+
+Run `common/all-versions/copyHAL.sh` to create a new version of the audio HAL
+based on an existing one.
+
+## Directory Structure
+
+* `2.0` -- version 2.0 of the core HIDL API. Note that `.hal` files
+  can not be moved into the `core` directory because that would change
+  its namespace and include path.
+   - `config` -- the XSD schema for the Audio Policy Manager
+     configuration file.
+* `4.0` -- version 4.0 of the core HIDL API.
+* ...
+* `common` -- common types for audio core and effect HIDL API.
+   - `2.0` -- version 2.0 of the common types HIDL API.
+   - `4.0` -- version 4.0.
+   - ...
+   - `7.0` -- version 7.0.
+      - `example` -- example implementation of the core and effect
+        V7.0 API. It represents a "fake" audio HAL that doesn't
+        actually communicate with hardware.
+   - `all-versions` -- code common to all version of both core and effect API.
+      - `default` -- shared code of the default implementation.
+         - `service` -- vendor HAL service for hosting the default
+           implementation.
+      - `test` -- utilities used by tests.
+      - `util` -- utilities used by both implementation and tests.
+* `core` -- VTS tests and the default implementation of the core API
+  (not HIDL API, it's in `audio/N.M`).
+   - `7.0` -- code specific to version V7.0 of the core HIDL API
+   - `all-versions` -- the code is common between all versions,
+     version-specific parts are enclosed into conditional directives
+     of preprocessor or reside in dedicated files.
+       - `default` -- code that wraps the legacy API (from
+         `hardware/libhardware`).
+       - `vts` VTS tests for the core HIDL API.
+* `effect` -- same for the effect HIDL API.
+   - `2.0`
+      - `config` -- the XSD schema for the Audio Effects configuration
+        file.
+   - `4.0`
+   - ...
+   - `all-versions`
+      - `default`
+      - `vts`
+* `policy` -- Configurable Audio Policy schemes.
+   - `1.0` -- note that versions of CAP are not linked to the versions
+     of audio HAL.
+      - `vts` -- VTS tests for validating actual configuration files.
+      - `xml` -- XSD schemas for CAP configuration files.

+     *
+     * Canonical example:
+     *   1) User requests an operation, such as fingerprint enrollment.
+     *   2) Fingerprint enrollment cannot happen until the user confirms their lockscreen credential
+     *      (PIN/Pattern/Password).

+     *      confirmation. It needs proof that the user explicitly authenticated credential in order
+     *      to allow addition of biometric enrollments.
+     * To secure this path, the following path is taken:
+     *   1) Upon user requesting fingerprint enroll, the framework requests
+     *      IFingerprint#generateChallenge
+     *   2) Framework sends the challenge to the credential subsystem, and upon credential
+     *      confirmation, a HAT is created, containing the challenge in the "challenge" field.
+     *   3) Framework sends the HAT to the HAL, e.g. ISession#enroll.
+     *   4) Implementation verifies the authenticity and integrity of the HAT.
+     *   5) Implementation now has confidence that the user entered their credential to allow
+     *      biometric enrollment.
+     *
+     * Note that the interface allows multiple in-flight challenges. For example, invoking
+     * generateChallenge(0, 0, timeoutSec, cb) twice does not invalidate the first challenge. The
+     * challenge is invalidated only when:
+     *   1) The provided timeout expires, or

+ *   1a) Cancellable state-based operations. If a cancellable operation is in-progress and the

+ *   1b) Non-cancellable state-based operations. These operations should fully complete before the
+ *       next state-based operation can be started.
+ *   2) Methods without a state. These methods may be invoked by the framework depending on its
+ *      use case. For example on devices with sensors of FingerprintSensorType::UNDER_DISPLAY_*,
+ *      ISession#onFingerDown may be invoked while the HAL is in SessionState::ENROLLING,
+ *      SessionState::AUTHENTICATING, or SessionState::DETECTING_INTERACTION.
+ *
+ * If the HAL has multiple operations in its queue, it is not required to notify the framework
+ * of SessionState::IDLING between each operation. However, it must notify the framework when all
+ * work is completed. See ISessionCallback#onStateChanged. For example, the following is a valid
