This package provides a simple way to typeset grammars written in Backus-Naur form (BNF).
\begin{presentcommand}
- \cmd{bnfexpr} \cmd{bnfannot}
+ \cmd{SimpleBNFDefEq}
\end{presentcommand}
-These commands are wrappers around \cmd{texttt} and \cmd{textit} respectively.
+This command is used to typeset the definition symbol separate a nonterminal from its productions. It defaults to \SimpleBNFDefEq. It can be redefined to customized output using \verb|RenewDocumentCommand|.
\begin{presentcommand}

+\end{presentcommand}
+This command is used to typeset the separator symbol between productions. It defaults to \SimpleBNFDefOr. It can be redefined to customized output using \verb|RenewDocumentCommand|.
