5/// ## Extract device-specific APKs from an existing APK set
6///
7/// If you have an existing APK set and you want to extract from it a subset of APKs
8/// that target a specific device configuration, you can use the `extract-apk` command
9/// and specify a device specification JSON, as follows:
10///
11/// ```sh
12/// `bundletool extract-apks
13/// --apks=/MyApp/my_existing_APK_set.apks
14/// --output-dir=/MyApp/my_pixel2_APK_set.apks
15/// --device-spec=/MyApp/bundletool/pixel2.json`
16/// ```
