It is often useful for a number of alternatives to be synchronised, so that they are changed as a group; for example, when several versions of the B(1) editor are installed, the man page referenced by I should correspond to the executable referenced by I. B handles this by means of I and I links; when the master is changed, any associated slaves are changed too. A master link and its associated slaves make up a I I.
