+# version 1.0 - december 10, 1998
+# version 2.0 - January, 2002 by Keith Vetter
+# KPV Nov 01, 2002 - added proxy mode
+# KPV Dec 21, 2002 - added extract window
+# version 2.5 - February, 2003 by Don Libes
+# DL Jan/Feb, 2003 - added date support, state save/restore, cmdline display

+# clientPort - port to which clients connect
+# serverHost - machine where real server runs
+# serverPort - port on which real server listens
+#
+# e.g. to snoop on http connections to a web server:
+# sockspy 8080 www.some.com 80
+# then client web browser should use a url like:
