Subject: The contrib/get-antlr-3.4 script: - Has no outdated reference to
 /usr/share/java/stringtemplate.jar (as discussed on the mailing list). -
 Attempts to determine if the computer is 64 or 32 bit and configure antlr
 appropriately. - Warns the user about it's guess. - Tells the user how to
 correct an incorrect guess.
