terminal String FIELD;

terminal SLASH, EOL;

You must tell the parser what are the terminal (leaf)

symbols in the grammar, and what are the non terminal

symbols in the grammar.

Also, for those terminals that have a value we must tell

the parser what is the datatype of the value, e.g, String,

Integer, Object, etc (note: it cannot be a scalar datype

such as int, char, etc)
