Here are the basic instructions for using the ENTCS macro package.
The files should work seamlessly with LaTeX2e and with pdfLaTeX.

Assuming you have retrieved the necessary files, then,
  1) Place the *.sty files in a directory where LaTeX looks for 
     input files. This can be the directory containing the source file
     for your paper.
  2) Read the file instraut.dvi file. This describes the generic
     set of files elsart.sty and elsart12.sty, upon which the entcs
     files are based. 
  3) (pdf)LaTeX and print the file example.tex.  This file describes how
     the ENTCS style files differ from the generic Elsevier article
     styles.  This file also provides a template for preparing your own
     paper for your Proceedings.  You simply can replace relevant
     material in example.tex with your own data.  
  4) If you run into problems, contact your Program Chairman or me at
     mwm@math.tulane.edu.
  5) When you're finished, send a copy of your source file, together
     with any macro files you need to your Program Chairman or whomever
     is handling the processing of the papers.
