    Consider:

    import config
       .
       .
       .
            if vars(config).has_key('unzip') and config.unzip != "":
                if not os.path.exists(config.unzip):
                    self.logger.die("unzip program not found at %s" % config.unzip)
                self.unzip = config.unzip 
            else:
                .
                .
                .

    References to config.unzip are flagged as errors, but they really aren't.  This is a fundamental problem with trying to statically check dynamic languages.

      Well, yes, there are some cases where there's no real way to know about that.

      Currently, the ways to deal with that are:

      1. Actually declare things in the module so that the analyzer can find those (e.g.: in the config module, declare the unzip as a variable)

      2. Put a comment on that line to silent the error (Just press Ctrl+1 in the line that has the error and an option will be presented for that)

      3. Silent all the import errors in the preferences

      4. If it's a class, you can put "@DynamicAttrs" in the docstring and it'll know that no errors should be raised from having that (maybe the same could be done for modules -- what do you think?)

      Cheers,

      Fabio
