##Usage

ebnfDiagram = require 'ebnf-diagram'

ebnfDiagram.fromText('''"EBNF defined in itself" {

	syntax     = [ title ] "{" { production } "}" [ comment ].
	production = identifier "=" expression ( "." | ";" ) .
	expression = term { "|" term } .
	term       = factor { factor } .
	factor     = identifier
	| literal
	| "[" expression "]"
	| "(" expression ")"
	| "{" expression "}" .
	identifier = character { character } .
	title      = literal .
	comment    = literal .
	literal    = "'" character { character } "'"
	| '"' character { character } '"' .
