Please note that running onsgmls without the -R switch on a network-exposed
server opens you up to a file-disclosure vulnerability! Carefully crafted
input can be used to gain access to any file on the server that the user
running onsgmls (the web server user, most likely) has read access to.

We strongly advice against modifying the "check" CGI application this way!
