Script to merge an authority into another
parameters :
\th : this version/help screen
\tv : verbose mode (show many things on screen)
\tf : the authority number to merge (the one that can be deleted after the merge).
\tt : the authority number where to merge
\tn : don't ask for confirmation (useful for batch mergings, should not be used on command line)
\tb : batch Merging
All biblios with the authority in -t will be modified to be "connected" to authority -f
SAMPLE :
./merge_authority.pl -f 2457 -t 531
Before doing anything, the script will show both authorities and ask for confirmation. Of course, you can merge only 2 authorities of the same kind.
