	Frame Number	Integer

Parameters
	Frame Directory	string

Description

	This module was intended to be used with the AVS 
Animator application.  The module hooks right up to the
Animator module or the read_frame_seq module.  This module
accepts images, one at a time.  The image is then converted
into the Abekas A60 yuv format - with the same dimensions of
the Abekas A60 yuv format - and outputted to a file in the 
Frame directory with a name corresponding to the frame number.
( i.e.  Frame Number 20 -- Filename : 20 )  If the image is
not the same size as the A60 image standard, then the AVS image
is centered within the view of the Abekas.  This works well
when you consider the degradation of the image borders on its path
to NCSC.

	This module was adpated from Ian Currington's write_abekas
module and Abekas Inc.'s sample to_yuv program in their manual.
It writes out a temporary file in between conversions.  The module
works fine - but it isn't pretty.
