# 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 the following three commands:
#
#           sudo mv birkmult.cls /usr/share/texmf-texlive/tex/latex/base/
#           sudo chmod 444 /usr/share/texmf-texlive/tex/latex/base/birkmult.cls 
#           sudo texconfig rehash
#
#         and then try "show file.tex" again.
