let output: string;
let lexer = new Lexer(input);
let parser = new Parser(lexer);

// This will tokenize everything and validate that the grammar is correct
// If anything goes wrong, this will throw.
try {
	parser.program();
}
catch(error) {
	// Handle the error.
}

// Example of emitting what you need
let emitter = new Emitter(parser)
                  .setEmployeeName("Eli")
                  .setProductName("Anchovies")
                  .setPrepReceivedDateBasic("...")
                  .setUseByDateBasic("...")
                  .setPrepDate("...");
					
// This will replace the product names, employee names, etc. with
// what you specified when creating the Emitter. If anything is
// not set that should be, this will throw.
try {
	output = emitter.emit();
}
catch(error) {
	// Handle the error.
