Subject: If Statement Help


Hi All

Im currently learning ruby and its going well. I have been looking at a
number of "guru" libraries such as DBI, CGI etc to try and learn by example.
I have noticed that a number of if statements have the following syntax eg: 

if File.name?

Can someone please explain the ? usage as I have searched all over the
Pragmatic Programmer pages with no answer. 

Thanks
