Flick FLI-format Animation Viewer v1.5 21 May 1995
--------------------------------------
This program plays FLI/FLC-format bitmapped animation files on any ECS,
AGA or EGS Amiga running OS2.04 or higher. FLI/FLC-format files are
produced by Autodesk Animator and Autodesk 3D Studio on a PC, as well
as by other programs.
The files in this archive may be distributed anywhere provided they are
unmodified and are not sold for profit.
Ownership and copyright of all files remains with the author:
Peter McGavin, 86 Totara Crescent, Lower Hutt, New Zealand.
