The "pruning" setting is an undocumented option in Century. I assume it has to
do with how bad moves are pruned from the search. The default setting is NONE
and the options are PRUNE BAD MOVES_1, _2, _3, and _4. Here's the relevant line
from the .eng file:

[Pruning = NONE]     * PRUNE BAD MOVES_1, PRUNE BAD MOVES_2, ...

I think Ed came up with the Prune.eng personality. I haven't seen any results
posted for this personality.
