More than one tape per run

[Toralf Lund]

I'm thinking about using more than one tape, i.e. set "runtapes" 
parameter to a value > 1, for my updated archival setup. Is there 
anything special I need to keep in mind when doing this? Also, how do I 
set up runspercycle in this case? Is it the total number of tapes 
runspercycle * runtapes, or just runspercycle?
