-/*****************************************************************************
-* "Gif-Lib" - Yet another gif library. *
-* *
-* Written by: Gershon Elber Ver 0.1, Jul. 1989 *
-******************************************************************************
-* Program to flip interlaced and non interlaced images in GIF files. *
-* Options: *
-* -q : quiet printing mode. *
-* -i : Force all images to be intelaced. *
-* -s : Force all images to be sequencial (non interlaced). This is default. *
-* -h : on-line help *
-******************************************************************************
-* History: *
-* 5 Jul 89 - Version 1.0 by Gershon Elber. *
-* 21 Dec 89 - Fix problems with -i and -s flags (Version 1.1). *
