This directory contains a program developed at the Stanford Exploration
Project, Geophysics Department, by Kamal Al-Yahya.  It was modified and
enhanced substantially by Christian Engel at the Rheinisch-Westfaelische
Technische Hochschule at Aachen, Germany, Department of Computer Science 4.

It seems as if Kamal isn't to the net anymore.

I have made several modifications on Kamal's version 0.93 from the net.
Thus I continued my revision numbering with 1.00. The actual revision is
version 2.2 1992/04/27 15:13:26.

If you modify this source, if you found some bugs, or if you have some
suggestions for improvements then e-mail me as well:


You can run the program either by
		tr2latex < file  > file.tex
		tr2latex file  > file.tex
You are most likely to get messages on the standard error telling
you about things it encounters and cannot do.

Now you have the translated document. Look at it and see if you
can spot a major error. Run it through latex. If it runs and produces
the dvi file, then print it. If you get latex error messages modify
the translated document accordingly and repeat the latex run, and so on.
I usually get away with one or two iterations.


And in 2009 it seems as if Christian Engel has vanished from the
Internet as well, so I have took over this project and updated the
build process for a modern UN*X system.
