# Run a Cockatrice client with disposable, per-profile settings.
#
# Every profile gets its own XDG data, cache, and config directories under
# build/dev/profiles/<name>/, so several clients can run side by side with
# separate settings and card databases.
#
# Unrecognised arguments are passed through to the client unchanged.
