# After signing in, the browser tries to open an adskidmgr:/login?code=… link.
# Copy it and run:
#
#   ./fusion-login.sh 'adskidmgr:/login?code=…&state=…' ['Bottle name']
#
# The link must reach the identity manager in the same bottle Fusion is running
# in, and the code expires within minutes. The identity manager lives in a
# folder named after the Fusion build, which changes on every update, so this
# finds the newest one instead of hard-coding it.
