FileNdx.cfg is default configuraion file;
Archives.cfg/Music.cfg describe settings specific to certain filelist;
General.cfg describes general settings (included by upper);
Templates.cfg in a template directory specifies settings for certain output format
(text/HTML/multi-file HTML).
In this configuration the following variables are used:
$Config - FileNdx.cfg includes $Config.cfg
$OutputPath - by default all output files are created there.
$BinOutputPath - by default binary output file is created there.
$TemplatePath - all templates are assumed to be there and Templates.cfg from this directory loaded.
This makes possible output format changing by changing this variable only!
