| Source: | |
| This is the 3.4 PyInstaller's fake site.py | |
| (see https://github.com/pyinstaller/pyinstaller/blob/develop/PyInstaller/fake-modules/site.py) | |
| with the addition of the original 2.7 cpython code (see https://github.com/python/cpython/blob/2.7/Lib/site.py ) | |
| and adapted for reducing the size of the resulting frozen code | |
| Purpose: | |
| having back additional commands (mainly help and quit) in the python shell | |
| Usage: | |
| after installing PyInstaller, rename this file to site.py and overwrite the existing PyInstaller one; | |
| on Windows 10: C:/Python27/Lib/site-packages/PyInstaller/fake-modules/site.py | |
| on Mac: /Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages/PyInstaller/fake-modules/site.py | |
