<?php

For compatibility and reusability of your code, PSR1 recommends that a file should introduce either new symbols (like classes, functions, etc.) or have side-effects (like outputting something, or including other files), but not both at the same time. The first symbol is defined on line 65 and the first side effect is on line 2.

/**
 * Base-class for storage and retrieval of translated entities.
 *
 * Please see the 'translatable' module for managing translations of database-content.
 *
 * <b>Usage</b>
 *
 * PHP:
 * <code>
 * _t('MyNamespace.MYENTITY', 'My default natural language value');
 * _t('MyNamespace.MYENTITY', 'My default natural language value', 'My explanatory context');
 * sprintf(_t('MyNamespace.MYENTITY', 'Counting %s things'), 42);
 * </code>
 *
 * Templates:
 * <code>
 * <%t MyNamespace.MYENTITY 'My default natural language value' %>
 * <%t MyNamespace.MYENTITY 'Counting %s things' s=$ThingsCount %>
 * <%t MyNamespace.MYENTITY 'Counting {count} things' count=$ThingsCount %>
 * </code>
 *
 * Javascript (see framework/javascript/dist/i18n.js):
 * <code>
 * ss.i18n._t('MyEntity.MyNamespace','My default natural language value');
 * </code>
 *
 * File-based i18n-translations always have a "locale" (e.g. 'en_US').
 * Common language names (e.g. 'en') are mainly used in the 'translatable' module
 * database-entities.
 *
 * <b>Text Collection</b>
 *
 * Features a "textcollector-mode" that parses all files with a certain extension
 * (currently *.php and *.ss) for new translatable strings. Textcollector will write
 * updated string-tables to their respective folders inside the module, and automatically
 * namespace entities to the classes/templates they are found in (e.g. $lang['en_US']['AssetAdmin']['UPLOADFILES']).
 *
 * Caution: Does not apply any character-set conversion, it is assumed that all content
 * is stored and represented in UTF-8 (Unicode). Please make sure your files are created with the correct
 * character-set, and your HTML-templates render UTF-8.
 *
 * Caution: The language file has to be stored in the same module path as the "filename namespaces"
 * on the entities. So an entity stored in $lang['en_US']['AssetAdmin']['DETAILSTAB'] has to
 * in the language file cms/lang/en_US.php, as the referenced file (AssetAdmin.php) is stored
 * in the "cms" module.
 *
 * <b>Locales</b>
 *
 * For the i18n class, a "locale" consists of a language code plus a region code separated by an underscore,
 * for example "de_AT" for German language ("de") in the region Austria ("AT").
 * See http://www.w3.org/International/articles/language-tags/ for a detailed description.
