             the vaults with this tag can be used in a game.

             If chosen, these maps will contain the stairs for that
             branch. Use "O" to place the stairs. If a branch has very
             few entries, a dummy entry is advisable to make sure the
             player doesn't get bored of the same few entries recycled
             ad nauseam.

             Note: if any TAG argument contains an "entry", the vault will 
                   be no longer eligible for random placement. (Currently, 
                   this just affects your choice of BAR when using uniq_BAR.)
