# Demo GIF for the README: one sender, three receivers, one transfer.
# Runs entirely on this machine: multicast over the loopback interface
# (hence --iface 127.0.0.1; on a real LAN you would omit it).

# Regenerate with:
#   cmake -S . -B build -DCMAKE_BUILD_TYPE=Release && cmake --build build
#   PATH="$PWD/build:$PATH" vhs docs/demo.tape

# Requires: vhs (https://github.com/charmbracelet/vhs), tmux.
