=head1 modify-database-pass.pl
Changes the MySQL or PostgreSQL password for some domain.
This command changes the password that a domain's administrator uses to
login to MySQL or PostgreSQL. The domain is selected with the C<--domain>
flag, the database type with C<--type> and the new password is set with the
C<--pass> flag.
Because this operation will change the actual MySQL or PostgreSQL password,
any application or scripts in the virtual server's directory that have the
database password in their configuration files will be broken until those
configurations are updated with the new username.
