PERL/PDF Need Help

[Gowtham <sgowtham@xxxxxxx>]

Fellas,

I am working on a small, pet project that requires me to 
upload a PDF document to the webserver. I know how to upload
any document and have documented it here:

 http://sgowtham.net/blog/2008/07/24/file-uploads-via-perl-and-cgi/

I know how to do it in PHP/MySQL but the server does not
have PHP on it (it's a golden oldie). Can any of you please
help me learn how do I make sure the uploaded document is
actually a PDF and not something funky?

Thanks for your time.

Regards,
g
