Reading a couple day old thread (on installing new ruby for shared
server), Lennon suggested looking at ruby 'shim'.

I think shim is a great idea.  It allows a minimal usage of my
personal space (compared to installing a whole ruby1.8 preview), and
permits 1.8 sematics until 1.8.2 officially surfaces and I can bug the
admins of my webhosting to install it globally.

Two problems / questions: 
  1. Where can I get it?  RAA gives ftp location to removed directory
(from the helium fiasco)
  2. Is there some updated version to cover the newest 1.8.2 preview?  
      (1.8.1 seemed to have a funny thing or two in it)

Thanks,
Cameron
