README for GNU DIFF

This directory contains the GNU diff, diff3, sdiff, and cmp utilities.
Their features are a superset of the Unix features and they are
significantly faster.

Please see the file COPYING for copying conditions.

Please see the file doc/version.texi for version information.

Please see the file doc/diffutils.texi (or doc/diffutils.info) for
documentation that can be printed with TeX, or read with the 'info'
program or with Emacs's 'M-x info'.  Brief man pages are in man/*,
but they are no substitute for the documentation.

Please see the file ABOUT-NLS for notes about translations.

Please see the file INSTALL for generic compilation and installation
instructions.  Briefly, you can run "./configure; make install".  The
command "./configure --help" lists the supported --enable and --with
options.

If you have a problem with internationalization, you might be able to
work around it as described in ABOUT-NLS by invoking './configure
--disable-nls'.  Many of the problems arise from dynamic linking
issues on non-GNU platforms (e.g. with the iconv library).  Such
problems tend to be shared by other GNU applications on these
platforms, and can usually be fixed by carefully tweaking your non-GNU
installation.  If you have an older version of libiconv, please
upgrade to the latest one; see <ftp://ftp.gnu.org/gnu/libiconv/>.  If
the problem seems isolated to diffutils, though, please report a bug.

This program requires a Standard C compiler (C99 or later).  If you
have a nonstandard compiler, please install GCC first.

If you make changes to the source code, you may need appropriate
versions of GNU build tools to regenerate the intermediate files.
See README-prereq for details.

For any copyright year range specified as YYYY-ZZZZ in this package
note that the range specifies every single year in that closed interval.

Please report bugs to <bug-diffutils@gnu.org>.
