# Syntax: From the command line, in a directory containing a
#         LaTeX file called "file.tex," enter "show file.tex" to
#         create and view a PDF file.  (If you get a LaTeX error
#         of the form "File `birkmult.cls' not found" and obtain
#         an unviewable PDF file, enter "cp birkmult.cls /tmp"
#         and try again.)
