 *   This file contains the class definition for the LinuxPrinterSetup
 *   Database (lpsdb). The database is a subclassed Qt QDomDocument with
 *   extended functionality to get information about manufacturers models
 *   and drivers.
 *   As the LinuxPrinterSetup project is splitted up into three different
 *   subprojects (PrinterDriverToXML, PrinterAutoSetup, PrinterManualSetup)
 *   but only one of it (PrinterDriverToXML) really writes to the Database,
 *   this library only contains methods to query the database read-only.
 *
 *   PLEASE NOTICE: If not stated otherwise, whenever we speak of 'printer
 *                  drivers' or simply 'drivers', we mean the PPD files
 *                  and not the actual drivers.
