\begin{subproof}*[hi]

\begin{proof}
Beginn des Beweises:
\begin{proof}*
Ein unterbeweis
\end{proof}
Jetzt sind wir fertig.
\end{proof}
\begin{theorem}\label{thm:krass}
Man sollte nach Würzburg fahren.
\end{theorem}
\begin{claim}

\begin{proof}

\begin{refproof}*{thm:krass}[hi]
\begin{claim}\label{cl:qed}
Der QED ist toll.
\end{claim}
Um \autoref{cl:qed} zu beweisen, brauchen wir zunächst ein Lemma.
\begin{proof}
\begin{claim}
test
\end{claim}
hi
\proofdepth
\end{proof}
\begin{claim}
hi
\end{claim}
\end{refproof}
\begin{claim}
next
\end{claim}
\begin{lemma}\label{lm:krass}
Mathevereine sind krass.
\end{lemma}
\begin{refproof}{lm:krass}[quasi ein Fakt]
\begin{claim}
Mathe ist cool.
\end{claim}
\begin{oldsubproof}
trivial.
\end{oldsubproof}
Damit folgt nun das Lemma.
\end{refproof}
Nun kommen wir wieder zurück zum eigentlichen Beweis:
\begin{refproof}{thm:krass}[hi]
\begin{claim}\label{cl:würzburg}
Der QED macht ein Seminar in Würzburg
\end{claim}
\begin{oldsubproof}
Zu prüfen in der DB. Fakt!
\end{oldsubproof}
Aus \autoref{cl:qed} und \autoref{cl:würzburg} folgt nun die Aussage.
\end{refproof}
