-     * IMPORTANT NOTE: The variables defined here must _not_ be 'final'.
-     *
-     * The reason for this is very subtle:
-     *
-     * - This template is used to generate several distinct, but similar
-     *   files used in different contexts:
-     *
-     *   o .../gen/templates/org/chromium/content/app/NativeLibraries.java
-     *
-     *     This file is used to build content.jar, which is the library
-     *     jar used by several content-based projects. However, the
-     *     corresponding NativeLibraries.class file will _not_ be part
-     *     of the final content.jar.
-     *
-     *   o .../$PROJECT/native_libraries_java/NativeLibraries.java
-     *
-     *     This file is used to build a content-based APK (e.g. $PROJECT
-     *     could be 'content_shell_apk'). Its content will depend on
-     *     this target's specific build configuration, and differ from
-     *     the source file above.
-     *
-     * - During the final link, all .jar files are linked together into
-     *   a single .dex file, and the second version of NativeLibraries.class
-     *   will be put into the final output file, and used at runtime.
-     *
-     * - If the variables were defined as 'final', their value would be
-     *   optimized out inside of 'content.jar', and could not be specialized
-     *   for every content-based program.
-     *
-     * This exotic scheme is used to avoid injecting project-specific, or
-     * even build-specific, values into the content layer. E.g. this is
-     * how the component build is supported on Android without modifying
-     * the sources of each and every Chromium-based target.
