How-to install and use magic-wormhole in Windows 10

1. If not already done, download and install Python for Windows from:
https://www.python.org/downloads/windows/
take the most recent stable release for Python 3.7 or Python 3.8

I used the Windows x86-64 executable installer:
https://www.python.org/ftp/python/3.7.6/python-3.7.6-amd64.exe

2. The package Python includes the pip application, but update it with
this command:
python -m pip install -U pip

3. Install magic-wormhole with this command:
pip install --user magic-wormhole

4. Add the path to Python scripts to your PATH environment variable,
replacing didier by your user name in the path below and case occurring
Python37 by Python38 if you installed Python version 3.8:
C:\Users\didier\appdata\Roaming\Python\Python37\Scripts

Then to know how to use it just type:
wormhole ?

For instance, let's say I want to send to someone else the python
installer I downloaded. After having typed this command:
wormhole send C:\Users\didier\Downloads\python-3.7.6-amd64.exe
I get this output:

Sending 26.8 MB file named 'python-3.7.6-amd64.exe'
Wormhole code is: 1-tradition-printer
on the other computer please run:

wormhole receive 1-tradition-printer

Juts tell you correspondent to type this command and the file transfer
will occur.
