This is the beginning of a module for use under CGI:: to sniff out what browser someone's really using, despite the fact that it claims to be "Mozilla" (can you say Micro$oft?). If you can provide me with User Agent values that call themselves "Mozilla", I'd appreciate it, and I'll add it. Right now, I've got: Any real version of Netscape Navigator Any version of Netscape Communicator Any version of MS Internet Explorer 2.0 or higher. To install this module, you need to: perl Makefile.PL make make install I've already made HTML documentation from tne embedded POD. It's in the doc/ directory.
