# Spin up Christian Huitema's picoquic reference server on UDP 4433.
# Picoquic is the IETF QUIC WG's reference impl and the most permissive
# server for a brand-new client to interop against — it logs detailed
# qlog traces and accepts a wide range of transport parameters.
#
# Usage:
#   quic/scripts/run-picoquic.sh                  # foreground, ^C to stop
#   quic/scripts/run-picoquic.sh -d               # detached
#
# Then in another terminal, drive our client:
#   ./gradlew :quic:jvmTest --tests '*InteropRunner*' \
#     -DinteropHost=127.0.0.1 -DinteropPort=4433
#
# Or compile + run the runner main directly:
#   ./gradlew :quic:jvmTestClasses
#   java -cp 'quic/build/classes/kotlin/jvm/{main,test}:…' \
#     com.vitorpamplona.quic.interop.InteropRunnerKt 127.0.0.1 4433
