=head1 disable-feature.pl
Turn off some features for a virtual server
This program is very similar to C<enable-feature>, and takes the same command
line parameters, but disables the specified features instead. Be careful when
using it, as it will not prompt for confirmation before disabling features
that may result in the loss of configuration files and other data.
If the C<--disassociate> flag is given, this command will simply remove the
association between the domain and the underlying system configuration or
database. For example, if disabling the MySQL with the C<--disassociate>
flag set, the underlying databases beloning to the domain would not be
removed.
