How can exclude some databases from backup?

[perrfect]

Hello.
Is it possible to exclude some databases from backup?
Is this option in the script?

For example:
I have more than 100 databases and want to backup all, but exclude one or two test databases.
In this case I run:
./couchdb_dump.sh -b -H 127.0.0.1 -d _all_dbs -s /var/lib/couchdb/backups
How can exclude a few databases?
