-******************* Sun Nov 17 02:19:34 CET 2002 *********************
-
-* fix fbmngplay to cope with 15bit displays that state they are 16bit
- (aty128fb on ppc)
-
-******************* Tue Sep 3 15:28:20 CEST 2002 ********************
-
-* get rid of dynamic positioning code (moved to theme config files
- for flexibility.
-
-******************* Mon Mar 18 14:56:29 CET 2002 *********************
-
-* rewrite console detection code.
-* fix console chosing code to show pictures on the right console
- only, when booting or shutting down the system.
-* get rid of obsolete code fragments.
-
-******************* Wed Sep 19 17:25:19 CEST 2001 ********************
-
-* gnore multiple USR1 signals to prevent halt animation to

-
-******************* Thu Sep 13 15:28:01 CEST 2001 ********************
-
-* new option -S to play on start console only.
-* new option -c to play animationon any fb console
-* split fbmngplay to several files.

-* fbmngplay *
-
-a simple fbcon based mng player
-
-This is a simple example program, using the kernel framebuffer device
-to display mng animation decoded by the new libmng implementation.
-
-This player is based on the SDL version included in the libmng package
-from Ralph Giles <giles@ashlu.bc.ca>. The code's fairly rough at this
-point, but there was no example player for *nix in the distribution.
-Patches welcome, of course.
-
-On a unix-like system, the build instructions are simple:
-
-(install and/or build the mng library from libmng.com)
-make
-make install
-
-To use the player:
-
-fbmngplay <filename>.mng <filename>.mng ...
-
-To stop looping animations, press CTRL C or send a TERM or INT signal.
-
-See the options with
-fbmngplay -h
