GNU diffutils

1.  Summary

	This fast-track introduces GNU diffutils, version 2.8.1,
	into the Solaris WOS.

	Patch release binding is requested.

2.  Discussion

	Diffutils is a set of utilities for displaying
	differences between text files.

	These utilities are commonly used by open-souce
	applications.  A version is included with the CBE tools
	for JDS, which is provided as a download on
	opensolaris.org.  They will also be used, if installed,
	by Mercurial.

	Diffutils is delivered as four command-line programs:
	cmp, diff, diff3, and sdiff.  Detailed information is
	available from the Diffutils website [1] and a copy of
        the manual is in the case directory.

	GNU diffutils is currently available in the Solaris
	Companion CD (CCD).  This proposal removes it from the
	CCD and adds it to the SFW consolidation.

	Non-GNU versions of these commands are already available
	in Solaris. These are not, however, fully compatible
	with the GNU variants, which are explicitly required by
	some applications.  The existing Solaris commands
	have identical names and are installed in /usr/bin.
	Therefore the GNU diffutils will be installed in
	/usr/gnu, with g-prefixed symbolic links to each
	command and manpage in /usr, as per the guidelines of
	PSARC/2007/047, /usr/gnu [2].
