To get the full functionality of the multiio module, you'll need
to have all of the following utilities (some come with your system,
some are Public Domain packages) in your path.  

	imconv          San Diego Supercomputer Center Image Tools
	convert         Image Magick
	compress	Comes standard with your UNIX system
	gzip            Gnu Zip 1.2.4
	cat 		Comes standard with your UNIX system
	gs		GhostScript2.6.1
	yuvtoppm        From the netpbmplus package
	picttoppm       From the netpbmplus package

Probably it will be most convenient to find those tools
that you don't already have at the IAC, where the
following tools (most with source code included) are 
stored in one large compressed tar file:
 
	GhostScript2.6.1 (gs)
	IMagickExtended (convert)
	SDSC_Image_Tools (imconv)
	gzip-1.2.4 (gzip)
	netpbmplus (yuvtoppm and picttoppm)

The address of this compressed tar file is
avs.ncsc.org:/misc_tools/multiio_tools/multiio_tools.tar.Z
This file is approximately 11MB in size. 

NOTE:   Only the SunOS 4.1.x version of imconv is stored in
        the compressed tar file.  If you're on another platform
        or OS, before going all the way to SDSC and trying to
        locate the version of imconv for your system, you should
        check the READ_ANY_IMAGE directory at the IAC first.  This
        is at avs.ncsc.org:/avs_modules/data_input/READ_ANY_IMAGE,
        and binary executables of imconv for several other platforms
        are stored there for you.
