Say I have a file called generator.php.  To hit this and pass arguments to
it, the URL looks something like:
http://www.something.com/generator.php?file=something.txt

I want to rename generator.php to just "generator" and have apache parse it
as a PHP file.  So when I hit it, it will look something like:
http://www.something.com/generator?file=something.txt

The reason being, I'm trying to replace a badly written CGI with this nice
graceful PHP script, but there are too many links to change other places to
have the URL be different.
