+
+	** main.cpp includes this file ! **
+
+	This source-file includes another system-dependet sourcefile called

+	#define INFO_SCSI_AVAILABLE
+        #define INFO_PARTITIONS_AVAILABLE
+	#define INFO_XSERVER_AVAILABLE
+
+	right now, there is the problem, that also the .desktop-files should
+	depend on the systemname, so that only available .desktop-files will
+	be copied to kde/applnk/Settings/Information !!
