The SDSC Image Tools are available for uploading via anonymous ftp from
'sdsc.edu' (132.249.20.22).  The anonymous ftp directory tree is structured by
machine architecture, and then by topic.  For instance, to get the SDSC Image
Tools for a Sun 4, use:

	ftp> cd sdscpub
	ftp> cd sun4
	ftp> cd graphics
		or
	ftp> cd [.sdscpub.sun4.graphics]

	ftp> type binary
	ftp> get IMTOOLS_V2_0_TAR.Z imtools_v2_0.tar.Z

For most architectures, software is bundled in both tar and cpio format and
compressed using the UNIX 'compress' utility.

Tool binaries, object library, release notes, and tool and library man pages
(nroff source, post-nroff text, and PostScript) are included.  Tool source
code is included.  Library source is not.  00README's and 00INDEX's in the
ftp directories explain their contents.  To get one of these, use:

	ftp> get 00README 00README
	ftp> get 00INDEX 00INDEX
