A short primer of how reference with an approximation of UWE Harvard style.
Note that it doesn't quite match the quirks of when UWE Harvard uses et.al. after the first time a reference is cited within your text (i.e. this template works according to the rules of the first time a piece is cited within text, rather than the subsequent modifications).
This project typesets the source code documentation for 3 TeX engines: Knuth's TeX, e-TeX or pdfTeX—by default it typesets the source code for e-TeX. All .tex source files were extracted from the original WEB source code after processing via a Web2C-based workflow. To typeset the documentation for a particular engine, just uncomment the relevant line in main.tex and comment out the others.
