if ( scalar(@ARGV) < 2 )
{
    print (<<USAGE);
Usage: $0 texxml_file_name or
       perl $0 -- texxml_file_name
       where "texxml_file_name" optionally includes the extension
Output: texxml_file_name.dvi

$0 renders texxml files into dvi files by copying the tex file
resulting from from texxml2latex.pl and the referenced eps files
into a temporary directory and running LaTeX on the .tex file.

If a second argument is passed, it is used as the location of the 
.eps files the document uses.

Must be run as somebody with permissions to write temp files and 
access /home/httpd/html/adm/help/eps.
