-// Implements a parser for an extended Backus-Naur form (BNF), producing the
-// binary context-free grammar format specified by llama.h. Supports character
-// ranges, grouping, and repetition operators. As an example, a grammar for
-// arithmetic might look like:
-//
-// root ::= expr
-// expr ::= term ([-+*/] term)*
-// term ::= num | "(" space expr ")" space
-// num ::= [0-9]+ space
-// space ::= [ \t\n]*
