Rebuild the Zebra indexes for Koha instances. The default behaviour
is to do an incremental rebuild.

Usage: $scriptname [options] instancename1 instancename2...
Options:
    --authorities|-a  Only run process for authorities.
    --biblios|-b      Only run process for biblios.
    --full|-f         Does a reindex of the whole collection.
    --force           Run incremental indexing even if USE_INDEXER_DAEMON="yes"
    --quiet|-q        Sometimes be a bit quieter for scripts/cronjobs.
    --verbose|-v      Be verbose. Can be multiple.
    --help|-h         Print this help.


Note: Any other options are passed directly to rebuild_zebra.pl.
