# Running socket tests with a remote server:
# ------------------------------------------
# 
# Some tests in socket.test depend on the existence of a remote server to
# which they connect. The remote server must be an instance of tcltest and it
# must run the script found in the file "remote.tcl" in this directory. You

# platforms that do not support exec, the remote server must be started
# by the user before running the tests.
