Implicit relative imports were removed in Python 3 to prevent
ambiguity as the number of packages grows. See PEP 328.
If you have two modules in the same package, pack1.mod1 and
pack1.mod2, then in pack1.mod1 you can no longer just do "import mod2"
or "from mod2 import foo". Either use an absolute import ("from
pack1.mod2 import foo") or make the relative import explicit ("from
.mod2 import foo" -- note the ".")
If you're upgrading scripts from Python 2 to Python 3, you should
really run them through the 2to3 tool. I believe this is one of the
many things it will fix for you automatically.
