/* The config file handler (not yet a real object)

 * much later. I began the file on 2008-02-19 as part of the modularization
 * effort. Over time, a clean abstration will become even more important
 * because the config file handler will by dynamically be loaded and be
 * kept in memory only as long as the config file is actually being 
 * processed. Thereafter, it shall be unloaded. -- rgerhards
