TextFile


[This file is README.TeX-XeT.
 It is intended for users of the UNIX TeX distribution.
 June 1990.]


The cxet.patch file makes TeX-XeT, a special enhancement of TeX which
will write special markers to distinguish right-to-left text from
left-to-right text.  See TUGboat Volume 8, No. 1, pp. 14--25 for details.

The current patch has been re-done for TeX3.0.  The patch is a context 
diff; so make sure that you are running a version of the patch utility 
that understands the form of a context diff.  (If you do not have this 
utility on your system, see the directory ../../patch, on this tape.)

To apply the patch save ctex.ch as ctex.ch.save (even though patch will 
save it for you as ctex.ch.orig).  

Then run

          % patch ctex.ch cxet.patch

You will get a couple of failures in the patching (patch reject files), 
but a small amount of hand-editing will take care of them.  The new 
ctex.ch is now ready for compilation into a large and bidirectional TeX
(please know that Big TeX is made by default during compilation).

Run the web2c makefile as for ordinary TeX, making sure you have protected 
the existing versions of initex and virtex from being clobbered.  

The output from compilation of TeX-Xet ought to be named initexxet and
virtexxet or something similar to keep it from being mistaken for
standard TeX.

Remember that you have changed ctex.ch.  It is a good idea to move the
ctex.ch.save file back into its original name after compilation to
avoid confusion.

The DVI output from TeX-Xet requires a special interpreter to deal with
these markers. 

A reversing dvi interpreter is available on the pub directory of
june.cs.washington.edu for ftp.  There, it is called ld_dvi2ps.tar.Z
It can be found on this tape in the directory ./DVIware/ivd2dvi.
