The chet package is inspired by Paul Ginsparg's harvmac, but uses LaTeX2e instead of TeX. The commands provided are to be used as faster alternatives to LaTeX's default environments (which can all still be used in chet). To use chet just copy chet.sty and chetref.bst in the folder of the TeX file you are compiling (or in your path) and include \usepackage{chet} in the preamble of your LaTeX file.
