 Fortunately, it is easy to replace the generic, interpreting GF parser
 by a compiled LR(1) parser. GF supports the translation of a concrete
-syntax into the \empha{Labelled BNF} (LBNF) format \cite{lbnf}, 
+syntax into the \empha{Labelled BNF} (LBNF) format, %% \cite{lbnf}, 
 which in turn can be translated to parser generator code
 (Happy, Bison, or JavaCUP), by the BNF Converter \cite{bnfc}.
 The parser we are therefore using in the compiler is a Haskell
