"""
Archipelago launcher for bundled app.

* if run with APBP as argument, launch corresponding client.
* if run with executable as argument, run it passing argv[2:] as arguments
* if run without arguments, open launcher GUI

Scroll down to components= to add components to the launcher as well as setup.py
