# 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

# 
#     % set remoteServerIP <name or address of machine on which server runs>
#     % set remoteServerPort 8048
# 
# These variables are also settable from the environment. On Unix, you can:
# 
#     shell% setenv remoteServerIP machine.where.server.runs
#     shell% senetv remoteServerPort 8048
#     shell% setenv remoteServerPort 8048
# 
# The preamble of the socket.test file checks to see if the variables are set
# either in Tcl or in the environment; if they are, it attempts to connect to
# the server. If the connection is successful, the tests using the remote
# server will be performed; otherwise, it will attempt to start the remote
# server (via exec) on platforms that support this, on the local host,
# listening at port 8048. If all fails, a message is printed and the tests
# using the remote server are not performed.
