This question may have been asked before, but I can’t find it.

How do I find what gem’s are installed on my InstantRails on Windows?  
I found “gem dependency rails” but I am looking for all the GEMS  
installed on this ROR installation, beside’s me going and looking in the  
Ruby directory.

Is there some command I can use?

thanks a million.
