BitCruncher is going through major refactoring so if you want stable version please use 1.0.2 release. SVN HEAD is usable but not extensively tested and may be buggy or have minor incompatibility issues.
Release 1.0.2 is out. It should fix all bugs from 1.0.1 and alternate configurations (-Dconfig=...) should now work as expected.
Release 1.0.1 has been pulled off since it contains serious usability bug in new feature: handling multiple configurations. Release 1.0.2 which fixes this issue is due today.
