    print (<<USAGE);
Usage: $0 texxml_file_name or
       perl $0 -- texxml_file_name [epssource] [--with-filenames]
       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.

If thre is a second argument, it will be used as the path to the 
eps files, otherwise "../../loncom/html/adm/help/eps" is used.

If the optional argument --with-filenames is included then
the filename for each fragment is stuck into the finished file.
