# ORNL Technical Memo LaTeX template

These are completely overhauled versions of the official ORNL report templates.

Unlike the old templates, the `ornltm`, `ornlspr`, and `ornlltr` classes are meant to separate the document

styling from your document's content. You should almost be able to replace the

`\documentclass{ornltm}` line in your file with

`\documentclass{elsarticle}` and submit it as a journal article.
