+# 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
+# can start the remote server on any machine reachable from the machine on
+# which you want to run the socket tests, by issuing:
+# 
+#     tcltest remote.tcl -port 2048	# Or choose another port number.
+# 
+# If the machine you are running the remote server on has several IP
+# interfaces, you can choose which interface the server listens on for
+# connections by specifying the -address command line flag, so:
+# 
+#     tcltest remote.tcl -address your.machine.com
+# 
+# These options can also be set by environment variables. On Unix, you can
+# type these commands to the shell from which the remote server is started:
+# 
+#     shell% setenv serverPort 2048
+#     shell% setenv serverAddress your.machine.com
+# 
+# and subsequently you can start the remote server with:
+# 
+#     tcltest remote.tcl
+# 
+# to have it listen on port 2048 on the interface your.machine.com.
+#     
+# When the server starts, it prints out a detailed message containing its
+# configuration information, and it will block until killed with a Ctrl-C.
+# Once the remote server exists, you can run the tests in socket.test with
+# the server by setting two Tcl variables:
+# 
+#     % set remoteServerIP <name or address of machine on which server runs>
+#     % set remoteServerPort 2048
+# 
+# These variables are also settable from the environment. On Unix, you can:
+# 
+#     shell% setenv remoteServerIP machine.where.server.runs
+#     shell% senetv remoteServerPort 2048
+# 
+# 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 2048. If all fails, a message is printed and the tests
+# using the remote server are not performed.
