[Rails] ubygems.rb file - is error?

Hi, I just installed Rails, and I was wondering what is this file?
/lib/ubygems.rb ?

Here is a copy of it:
https://github.com/rubygems/rubygems/blob/master/lib/ubygems.rb

Is this a bug/type (ubygems rather than what it should be, ubygems) or
is it supposed to be that way? If so, what does it do, could someone
explain how it works? (sorry if it's a dumb question I'm new at this!)

Thanks
