Perhaps I should ask this question in the Game Development QA. But I am using the Löve2D Engine on Ubuntu 14.04, and this is technically an OS management situation, so here it goes:
The current version (the one I installed) is 0.9.1, but some projects will only run with version 0.8.*. I know I can install different versions of the engine.
How do I install another version alongside the current one?
And how do I switch between versions?
