    Which MDB entries correspond to these new variables? The mdb-syntax file has many cache variables added to it.

    It would be better, but I don't know how.

    Cactus already has configuration variables for this and tries to guess the values while building. This can be wrong, since it builds on the head node, which often has a different cache configuration. In addition, I've begun to collect this information (which is difficult to find, I usually have to inquire with the help desk staff) in the MDB.
