   40: $0 renders texxml files into dvi files by copying the tex file
   41: resulting from from texxml2latex.pl and the referenced eps files
   42: into a temporary directory and running LaTeX on the .tex file.
   43: 
   44: If a second argument is passed, it is used as the location of the 
   45: .eps files the document uses.
   46: 
   47: Must be run as somebody with permissions to write temp files and 
   48: access /home/httpd/html/adm/help/eps.
   49: 
   50: If thre is a second argument, it will be used as the path to the 
   51: eps files, otherwise "../../loncom/html/adm/help/eps" is used.
   52: 
   53: If the optional argument --with-filenames is included then
   54: the filename for each fragment is stuck into the finished file.
