+During test the Kanatest displays randomly selected kana char (respecting mode
+and lesson) and waits for user answer expected as romaji equivalent.  This
+process continues until all questions will be answered or all questions will
+be answered correctly (depends on options).  At the end of test a short info
+about drilling time and correctness ratio is displayed.  The results are
+stored and user can review his performance in any time.")
