+# Argenta
+
+### Bibliothek zum Erstellen modularer CLI-Anwendungen
+
+Mit Argenta können Sie die CLI-Funktionalität in isolierte, abstrahierte Umgebungen einkapseln. Zum Beispiel: Sie erstellen ein Dienstprogramm ähnlich dem Metasploit Framework, bei dem der Benutzer zuerst in einen bestimmten Scoop eintritt (z. B. ein Modul zum Scannen auswählt) und dann auf eine Reihe von Befehlen zugreift, die nur für diesen Kontext spezifisch sind. Argenta bietet eine einfache und prägnante Möglichkeit, eine solche Architektur zu konstruieren.

+# Argenta
+
+### Библиотека для создания модульных CLI приложeний
+
+Argenta позволяет инкапсулировать CLI фукциональность в изолированные, абстрагированные **среды**. К примеру: вы создаете утилиту, подобную Metasploit Framework, где пользователь сначала входит в определенный скоуп (например, выбирает модуль для сканирования), а затем получает доступ к набору команд, специфичных только для этого контекста. Argenta предоставляет простой и лаконичный способ для построения такой архитектуры.
