How to view two info files at the same time?

[Hu, Wei]

I searched the internet for the solution but failed.
I only saw this in XEmacs FAQ:

Subject: Q5.0.17 How can I get two instances of the Info buffer to view two
info files at the same time? [new]
   You can't. The info package does not provide for multiple info buffers.

But what if I use Emacs? Is there any extension that can do this task?

Thank you very much.
