setenv CVSROOT firstname.lastname@example.org:/space/CVSwhere username is the developer's username on the CVS server software.sandia.gov. Since Zoltan is part of Trilinos, it is best to check out Trilinos from the repository:
cvs checkout -P TrilinosZoltan is then in directory Trilinos/packages/zoltan.
Alternatively, one can get a working copy of only the Zoltan software:
cvs checkout -P zoltanHowever, changes to the Autotools build environment require directories above the Zoltan directory in the Trilinos repository, so it is best to check out the entire Trilinos repository.
