该脚本主要利用Cython对Python项目进行加密，并通过distutils和Cython.Build模块构建扩展。它遍历指定目录下的.py和.pyx文件，排除某些文件，然后进行编译和复制操作。在Ubuntu环境下，需要安装python3-dev和gcc作为依赖。执行python3setup.pybuild_ext后，会生成加密后的项目副本。

# 环境 ubuntu
# 依赖
# sudo apt install python3-dev gcc
# pip3 install cython

# Python文件加密 parent_path 项目的目录名字，例如 parent_path = project_name
# setup.py放下根目录下
# 执行 python3 setup.py build_ext
# project_name_build 覆盖掉project_name 执行命令 mv project_name_build ../project_name
