# Current reverse engineering for figuring out the jar:
# 1. curl the current script:
#        https://bit.ly/cl4lx
#        ->
#        https://launcher.crystal-launcher.net/linux/install.sh
#    Here we can find the launcher icon.
# 2. Fetch the launcher.tar.xz mentioned there
# 3. The 'launcher' binary inside is a PyInstaller package.
#    It can be unpacked via:
#        https://github.com/extremecoders-re/pyinstxtractor
#    There is the web version here:
#        https://pyinstxtractor-web.netlify.app/
# 4. Unpack the .zip file, it has a bunch of .pyc files.
#    You can decompile it via pycdc.
#    Focus on the Crystal*.pyc.
#    The main manifest is available here:
#        https://launcher.crystal-launcher.net/bootstrapNX/data/bootstrapManifest.json
#    It also stores the Java version to use
# 5. We have the proper JAR and command line path for the launcher.
