; If set to true and a user is deleted, the respective database gets
; deleted as well.

[vhosts]
;example.com = /database/
; To create an admin account uncomment the '[admins]' section below and add a
; line in the format 'username = password'. When you next start CouchDB, it
; will change the password to a hash (so that your passwords don't linger
; around in plain-text files). You can add more admin accounts with more
; 'username = password' lines. Don't forget to restart CouchDB after
; changing this.
