Usage: $(basename $0) [Options]
Script creates a MySQL database. The database name is either given on command
line using parameter '-d' or will be asked for otherwise.
Options:
-d <db-name>
The name of the domain, which is requested for deletion. If not set, script
will ask for the database name.
-I
Non-interactive mode. Script will act in non-interactice mode. At least the
database name must be given using parameter '-d'. Default is acting in
interactive mode
-p <db-passwd>
Password for the given user. If not set, script looks for a file named
'databases/<db-name>'. If found, script reads database password from that file.
If not running in quiet mode, you will be asked to confirm or set the db-user.
-q
Be quiet. Setting this parameter implies non-interactive mode (parameter -I). So
if '-q' is set, at least the database name must be given using parameter '-d'.
-u <db-user>
The name of the database user who will be granted full access to the given
database. If not set, script looks for a file 'databases/<db-name>'. If
found, script reads database settings (user/password) from that file. If not
running in quiet mode, you will be asked to confirm or set the db-user.
