The app-strings module is deprecated.
If its functionality is still considered useful it will be added
to the l10n module,
otherwise it will just be removed.
The `app-strings` module gives you access to the host application's localized
string bundles (`.properties` files).
The module exports the `StringBundle` constructor function. To access a string
bundle, construct an instance of `StringBundle`, passing it the bundle's URL:
var StringBundle = require("app-strings").StringBundle;
var bundle = StringBundle("chrome://browser/locale/browser.properties");
To get the value of a string, call the object's `get` method, passing it
the name of the string:
var accessKey = bundle.get("contextMenuSearchText.accesskey");
// "S" in the en-US locale
To get the formatted value of a string that accepts arguments, call the object's
`get` method, passing it the name of the string and an array of arguments
with which to format the string:
var searchText = bundle.get("contextMenuSearchText",
["universe", "signs of intelligent life"]);
// 'Search universe for "signs of intelligent life"' in the en-US locale
To get all strings in the bundle, iterate the object, which returns arrays
of the form [name, value]:
for (var [name, value] in Iterator(bundle))
console.log(name + " = " + value);
Iteration
