# Minimal integration test: a server accepts one connection and prints
# whatever the client sent. No handshake protocol between the two --
# just a short sleep to give the server time to start listening before
# the client connects.
#
# Usage:
#   make test              # build and run with mhs (default)
#   make test HC=ghc       # build and run with GHC, against the library source
#   make clean
