# To permit this cgi, replace # on the first line above with the
# appropriate #!/path/to/perl shebang, and set this script executable
# with chmod 755.

# Note that it is subject to cross site scripting attacks on MS IE
# and any other browser which fails to honor RFC2616, so never use
# it in a live server environment, it is provided only for testing.
