+2003-03-30 Cesar Octavio Lopez Nataren <cesar@ciencias.unam.mx>
+
+ * Added this ChangeLog file.
+
+ * ast.cs: Added this file. Contains the classes used for building
+ the EcmaScript 's AST.
+
+ * JScript*: These are the files generated by antlr (the parser generator).
+
+ * TODOAttribute.cs: Changed the namespace in order to use it freely on Microsoft.JScript.
+
+ * driver.cs: Added this file. Contains the compiler entry point. And some Reflection.Emit methods,
+ that will be moved to other file in the future.
+
+ * jscript-lexer-parser.g: The EcmaScript's antlr grammar.
