The Powershell script (*.ps1) equivalent to the Linux Bash script is
used under Windows as a frontend to the Docker image of MsSpec.
It is converted to an *.exe file (msspec.exe) which is installed
by the setup program (msspec_setup.exe) created by Inno Setup using
the *.iss scripts. The end user will just download the msspec_setup.exe
file.
