+ * getlength - a small tool to get the length of a VDR recording by the size

+ *
+ * (c) by Martin Prochnow
+ * Distributed under the terms of the GPL v2.0 (see COPYING at the root dir of
+ * this archive).
+ *
+ * Compile with: gcc getlength.c -o getlength
+ *
+ * Usage: 'getlength' if index.vdr is in the current working directory or
+          'getlength /PATH/TO/RECDIR/' else
