// | Plugin. By default this program will automatically create all required    | 
// | Tables, groups, security rights and group assignments.                    |

// | I have extended the standard PLUGIN Install script with a admin controls  | 
// | These are set in the install.cfg file. By default - all are set to true   | 
// | for auto install/deinstall operation. But if you are upgrading or had     | 
// | some problems, these switches let you control the install/deinstall       | 
// |                                                                           |
