This installation shell script will examine your system and ask you questions
-to determine how the perl package should be installed. If you get
+to determine how the perl5 package should be installed. If you get
stuck on a question, you may use a ! shell escape to start a subshell or
execute a command. Many of the questions will have default answers in square
brackets; typing carriage return will give you the default.
If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
the questions and use the computed defaults (or the previous answers if there
was already a config.sh file). Type 'Configure -h' for a list of options.
+You may also start interactively and then answer '& -d' at any prompt to turn
+on the non-interactive behaviour for the remainder of the execution.

Much effort has been expended to ensure that this shell script will run on any
Unix system. If despite that it blows up on yours, your best bet is to edit
-Configure and run it again. Also, let me (lwall@netlabs.com)
-know how I blew it. If you can't run Configure for some reason, you'll have to
-generate a config.sh file by hand.
