// Resource Manager exposes an assembly's resources to an application for
// the correct CultureInfo. An example would be localizing text for a
// user-visible message. Create a set of resource files listing a name
// for a message and its value, compile them using ResGen, put them in
// an appropriate place (your assembly manifest(?)), then create a Resource
// Manager and query for the name of the message you want. The Resource
// Manager will use CultureInfo.GetCurrentUICulture() to look
// up a resource for your user's locale settings.
//
// Users should ideally create a resource file for every culture, or
// at least a meaningful subset. The filenames will follow the naming
// scheme:
//
// basename.culture name.resources
//
// The base name can be the name of your application, or depending on
// the granularity desired, possibly the name of each class. The culture
// name is determined from CultureInfo's Name property.
// An example file name may be MyApp.en-US.resources for
// MyApp's US English resources.
