30 * Localization System
31 *
32 * This framework handles localization. Localization in new ISSO
33 * applications is done through this framework. Nearly all strings
34 * are passed to the string function, which looks up the string in
35 * a .strings.xml file during runtime. Before release, mkstrings
36 * creates the .strings.xml file for translators. Common strings
37 * can be accessed through the get lex function which calls a string
38 * based on unique identifier; this is useful for commonly used strings.
