How to run leda 12.1 in a sandbox to avoid corrupting a 12.0 install ?

Hi,

I use intellij for work, this I need a working install. I would like to be able to test leda on some projects to check its viability for me before I commit to it.

From what I have seen, on my install on mac osx, there are a few "shared path"

./Library/Application Support/IntelliJIdea12

./Library/Caches/IntelliJIdea12

./Library/Logs/IntelliJIdea12

./Library/Preferences/IntelliJIdea12

and possibly more ... I am not sure how much leda will change these shared paths compared to intellij but I know for sure that for plugins it can be a problem.

Is there a way to make 12.1 _not_ use the same shared folders as 12.0 ?

Thanks

Jean
