I'm confused, what does the @rails3 do when creating a new gemset?
I want to run both rails2.1.1 and rails3 applications, and switch between the two.
I create a rvm for 1.9.2 and 1.8.7
And inside 1.9.2 I created 2 gemsets, and installed rails 2.1.1 in one gemset, and rails3 in another gemset.
Am I doing this right?
I'm reading others use the @rails3 in the gemset creation process, and it helps isolate things?? Can someone explain this as I don't get it.
Should I delete the gemsets and start over? or is it higher up that I have to delete?
