please pay a bit more attention on how you name things!
What does this part do?
Also this is the name which will be placed into the bin folder.
So we want something there, which makes sense.
And please generate a package and test if it works ;)

We have a problem with this recipe. It only runs when we run buildout. Thats not what we want here. We need to create a script in bin folder. I'll copy my comments from the chat here too, for documentation:

We could use Python entry points for the locales script. We can't use a shell script, because we want also support windows. If we have a simple entry point, we could let buildout generate a script in the bin folder, as we do for the zopepy script for example.
