问题：
The Situation 情况
I'm trying to port an open-source library to Python 3. ( SymPy , if anyone is wondering.) 我正在尝试将开放源代码库移植到Python3 。（ SymPy ，如果有人想知道的话。）
So, I need to run 2to3 automatically when building for Python 3. To do that, I need to use distribute . 因此，在为Python 3进行构建时，我需要自动运行2to3 。为此，我需要使用distribute 。 Therefore, I need to port the current system, which (according to the doctest) is distutils . 因此，我需要移植当前系统（根据doctest）是distutils 。
The Problem 问题
Unfortunately, I'm not sure what's the difference between these modules— distutils , distribute , setuptools . 不幸的是，我不确定这些模块（ distutils ， distribute ， setuptools之间有什么区别。 The documentation is sketchy as best, as they all seem to be a fork of one another, intended to be compatible in most circumstances (but actually, not all)…and so on, and so forth. 该文档最好是粗略的，因为它们似乎是彼此的一个分支，旨在在大多数情况下兼容（但实际上并非全部）……等等。
The Question 问题
Could someone explain the differences? 有人可以解释差异吗？ What am I supposed to use? 我应该用什么？ What is the most modern solution? 什么是最现代的解决方案？ (As an aside, I'd also appreciate some guide on porting to Distribute , but that's a tad beyond the scope of the question…) （顺便说一句，我也很感谢有关移植到Distribute一些指南，但这超出了问题的范围……）
