I am occasionally asked what ``word processor'' I use to produce
my course notes and assignments.  Well, I dislike word processors
very much and wouldn't be caught using one.  Instead,
I use a typesetting system developed by Donald Knuth
known as <I> TeX </I> (pronounced ``Teck'').  More precisely, 
I use a special
package of TeX macros called <I>LaTeX</I> (``Layteck'')
which enables writers to prepare camera ready copy with publishing
house quality.  


To learn more about LaTeX, check out 
<A href="http://www.cogs.sussex.ac.uk/cgi-bin/texfaq2html">TeX FAQ.
</a> 
The last time I looked, question number one was ``What is TeX?''
<P>
If you want to get a version of LaTeX up and running on your PC,
I have written some <a href="http://www.math.mun.ca/~edgar/miktex.html">notes</a>
which might help.
<P> The LaTeX process generates "dvi files", that is, files with the 
extension <em>.dvi</em>.  Others are "postscript files", which have
the extension <em>.ps</em>.  Today, the most popular output is "pdf"
because such files are readable with 
the <a href="http://www.adobe.com/products/acrobat/"> adobe reader </a>
which everybody has on their PCs nowadays.
