/**
|
|
* SilverStripe-variant of the "gettext" tool:
|
|
* Parses the string content of all PHP-files and SilverStripe templates
|
|
* for ocurrences of the _t() translation method. Also uses the {@link i18nEntityProvider}
|
|
* interface to get dynamically defined entities by executing the
|
|
* {@link provideI18nEntities()} method on all implementors of this interface.
|
|
*
|
|
* Collects all found entities (and their natural language text for the default locale)
|
|
* into language-files for each module in an array notation. Creates or overwrites these files,
|
|
* e.g. framework/lang/en.yml.
|
|
*
|
|
* The collector needs to be run whenever you make new translatable
|
|
* entities available. Please don't alter the arrays in language tables manually.
