The launcher looks at directory "Versions" next to its executable.
It finds the latest version and runs the executable in that directory
with the same name as itself. For instance:
Aminal.exe <- the launcher
Versions/
1.0.0/
Aminal.exe
1.0.1/
Aminal.exe
In this example, running the top-level Aminal.exe (the launcher) starts
Versions/1.0.1/Aminal.exe.
Having a launcher allows Aminal to be updated while it is running. For
example, version 1.0.1 could be downloaded without disturbing running
instances of Aminal 1.0.0.
