Latex is a somewhat complicated language that is best understood by reading an example of it. Towards that end, we've written a brief tutorial on how to use Latex under Eniac. There are two archives you can choose to use, a zip archive or a tarball. They both have exactly the same contents, namely, A PDF version of the tutorial, as well as the Latex file that the tutorial was generated from. If you are unfamiliar with Latex, download one of the files and work on it on your own. If you are familiar with Latex, there is no need to read through this tutorial, although the makefile may be handy for you.
