blanchet [Tue, 24 Feb 2009 16:12:27 +0100] rev 30237
Eliminated ZCHAFF_VERSION configuration variable, since zChaff's output format is identical in all versions since March 2003 (at least), and also because it forces users who want to use the latest versions to lie about the version number.
I also made the BERKMIN_EXE variable optional, defaulting to BerkMin561 (a reasonable name with no platform encoded in it).
These changes have no inpacts on already working Isabelle installations.
