I’ll readily admit that I haven’t looked into this much yet. I  
thought I would ask here first and get the 10,000 foot view and  
pointers for where to dig further.

I’m interested in RubyGems multiple versions feature. I need to be  
able to select the version that runs at any given time. The  
complication is that the gem installs a bin/ script that is the  
primary interface. Can someone explain how RubyGems handles that?

Thanks.

I think it is just

myapp _1.2.3_ --options-to-my-app args\_for\_my\_app

where 1.2.3 is the version you want to run.  
Otherwise, it runs the latest version.

Is that what you are asking?

Sure is. Wow, that was easy. Thanks much!
