+the ABNF grammar format as described in RFC2234.  The generated parser is a
+regular expression scanner provided by the cl-ppcre lib, which means that we
+can't parse recursive grammar definition.  One such definition is the ABNF
+definition as given by the RFC.  Fortunately, as you have this lib, you most
+probably don't need to generate another parser to handle that particular ABNF
+grammar.")
