Since the Lua does not guarantee backward compatibility the best solution
IMO would be the list all versions to which the rocks are intended to work.
It doesn't really make sense to use a '>=' operator once new Lua releases
can actually break current implementation.
Something like "lua = 5.1 or 5.2" makes more sense for me. But wait, in
fact in this case the ">=" operator is saying exactly the same thing. :-/
Maybe the real problem is lack of validation. We should assume that when
one puts "lua >= 5.1" then he is saying "lua5.2 is ok for me" but if he
didn't test the code there's a failure in the development process not in
the versioning. The code will work for lua5.1 and will have a bug for
lua5.2.
Let's supose one restricts the max lua version specifying <5.2. If this guy
doesn't test his 5.1 code, it has a chance to break as well, despite the
fact he has "correctly" specified de lua dependency.
The problem is a bit complex due to the nature of new Lua releases.
