+/**
+ * Native Android logging for JavaScript.  Lets you specify a priority and tag
+ * in addition to the message being logged.  Resembles the android.util.Log API
+ * <http://developer.android.com/reference/android/util/Log.html>.
+ *
+ * // Import it as a JSM:
+ * let Log = ChromeUtils.import("resource://gre/modules/AndroidLog.jsm")
+ *   .AndroidLog;
+ *
+ * // Use Log.i, Log.v, Log.d, Log.w, and Log.e to log verbose, debug, info,
+ * // warning, and error messages, respectively.
+ * Log.v("MyModule", "This is a verbose message.");
+ * Log.d("MyModule", "This is a debug message.");
+ * Log.i("MyModule", "This is an info message.");
+ * Log.w("MyModule", "This is a warning message.");
+ * Log.e("MyModule", "This is an error message.");
+ *
+ * // Bind a function with a tag to replace a bespoke dump/log/debug function:
+ * let debug = Log.d.bind(null, "MyModule");
+ * debug("This is a debug message.");
+ * // Outputs "D/GeckoMyModule(#####): This is a debug message."
+ *
+ * // Or "bind" the module object to a tag to automatically tag messages:
+ * Log = Log.bind("MyModule");
+ * Log.d("This is a debug message.");
+ * // Outputs "D/GeckoMyModule(#####): This is a debug message."
+ *
+ * Note: the module automatically prepends "Gecko" to the tag you specify,
+ * since all tags used by Fennec code should start with that string; and it
+ * truncates tags longer than MAX_TAG_LENGTH characters (not including "Gecko").
