+#
+# This Expect script was generated by autoexpect on Mon Apr  2 09:44:34 2007
+# Expect and autoexpect were both written by Don Libes, NIST.
+#
+# Note that autoexpect does not guarantee a working script.  It
+# necessarily has to guess about certain things.  Two reasons a script
+# might fail are:
+#
+# 1) timing - A surprising number of programs (rn, ksh, zsh, telnet,
+# etc.) and devices discard or ignore keystrokes that arrive "too
+# quickly" after prompts.  If you find your new script hanging up at
+# one spot, try adding a short sleep just before the previous send.
+# Setting "force_conservative" to 1 (see below) makes Expect do this
+# automatically - pausing briefly before sending each character.  This
+# pacifies every program I know of.  The -c flag makes the script do
+# this in the first place.  The -C flag allows you to define a
+# character to toggle this mode off and on.
+
+set force_conservative 0  ;# set to 1 to force conservative mode even if
+			  ;# script wasn't run conservatively originally
+if {$force_conservative} {
+	set send_slow {1 .1}
+	proc send {ignore arg} {
+		sleep .1
+		exp_send -s -- $arg
+	}
+}
+
+#
+# 2) differing output - Some programs produce different output each time
+# they run.  The "date" command is an obvious example.  Another is
+# ftp, if it produces throughput statistics at the end of a file
+# transfer.  If this causes a problem, delete these patterns or replace
+# them with wildcards.  An alternative is to use the -p flag (for
+# "prompt") which makes Expect only look for the last line of output
+# (i.e., the prompt).  The -P flag allows you to define a character to
+# toggle this mode off and on.
+#
+# Read the man page for more info.
