怎么实现 pypi 安装后在$path 目录下增加可执行文件？

像 you-get 一样

$ pip3 install you-get
$ which you-get
/usr/local/bin/you-get
$ cat /usr/local/bin/you-get
#!/usr/local/opt/python/bin/python3.7

# -*- coding: utf-8 -*-
import re
import sys

from you_get.__main__ import main

if __name__ == '__main__':
    sys.argv[0] = re.sub(r'(-script\.pyw?|\.exe)?$', '', sys.argv[0])
    sys.exit(main())

查看了源码和 setup.py ，并没有看出什么端倪。
