2022-07-25: new-wlan.ps1 offers the same functionality as the batch file below, but is written in
PowerShell.

After creating the profile XML file, it uses
netsh wlan add profile to create a profile for the given SSID and
netsh wlan connect connect to the newly created profile.
The batch file is invoked with an SSID and an optional password:
C:\> new-wlan THE_SSID
C:\> new-wlan THE_SSID "My Secret Garden"
The batch file itself is:
