  Gemsync syncs the current version of ruby with the one given.    
  
  This tool is fairly dumb. Syncing across implementations is 
  probably a bad idea.
  
  Examples:

syncs ruby 1.8.6 with the gems install for 1.9.1

C:\\>ruby -v
ruby 1.8.6 (2009-03-31 patchlevel 368) [i386-mingw32]

C:\\>pik gemsync 191 p2
Gem ZenTest-4.1.4.gem already installed
Installing xml-simple-1.0.12.gem
Successfully installed xml-simple-1.0.12
1 gem installed

  You appear to be attempting a gemsync from a different platform.  
  
Sync: #{current}
with: #{source}

  If you really want to sync, I recommend you quit and run gemsync with
  the --remote flag.
