# in the synced copy (see scripts/_env.sh).
# Usage: scripts/frame.sh [--host] [-C subdir] command [args...]
#   --host      run on the SteamOS host instead of the container
#   -C subdir   start in <repo>/<subdir> (default: the repo root)
# The command is passed to a shell as one string, like ssh does.
