A grammar naturally describes the hierarchical structure of many programming language contructs. This structure is normally expressed as a set of rules or productions. In a production, lexical elements like the keywords and tokens can be intermixed with variables and non-terminals. Each production consists of a non-terminal, called the left-side of the production, an arrow, and a sequence of tokens and/or non-terminals, called the right-side of the production.
