+ * TeplFileLoader tries to delegate as much work as possible to other internal
+ * classes:
+ * - TeplFileContentLoader
+ * - TeplFileContent
+ * - TeplEncodingConverter
+ *
+ * Those internal classes should be re-usable outside of GtkTextView, the
+ * GtkTextView-specific code should be in this class.
