installing Doorstop on macOS (for RTEMS use)

[Sebastian Huber]

Hello Chris,

I know that you don't like homebrew based solutions on macOS. The 
reasons for this are understandable. This is why I suggested to use the 
installer from python.org:

There are Python 3 installers available for macOS from python.org:

https://www.python.org/downloads/mac-osx/

According to the pip project site it is already installed for Python 2 
 >=2.7.9 or Python 3 >=3.4:

https://pip.pypa.io/en/stable/installing/

For example to install Python 3.7.4 on macOS you can use:

https://www.python.org/ftp/python/3.7.4/python-3.7.4-macosx10.9.pkg

I don't have a Mac and cannot test this.

The Python 2.7 end of life is in 2 months and 20 days (January 1, 2020). 
The first Python 3 release was in 2008. Are there plans from Apple to 
update their Python support in Xcode to a state of the art version? 
Using the doorstop tool is not absolutely necessary right now. The file 
format is so easy, you can do almost everything with a text editor by 
hand (and scripts). What you cannot easily do is the calculation of the 
fingerprint, however, this can be done by the one who commits a patch. 
So, in case a Python 3 support with pipenv is on the Apple roadmap for 
the next year, this would make this easier.
