+// WRITE A CORRECT GRAMMAR FOR THE TINY LANGUAGE IN THIS FILE.
+//
+// The grammar is described in data/tinyGrammar.pdf. Do not use dashes
+// in your non-terminal names. I recommend you use mixed case naming for your
+// non-terminals instead (e.g. stmtSeq).
+//
+// Do not put any string literals in this grammar (e.g. "="). Use only token
+// names given in TinyLexer.tokens.
+//
+// This file contains an expression grammar that uses tokens described in
+// TinyLexer.tokens.
+//
+// NOTE ONE ERROR in the pdf: the second production rule should read:
+//    stmt-seq -> stmt-seq stmt | stmt
