cat <<EOH
 
This installation shell script will examine your system and ask you questions
to determine how the $package 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.

On some of the questions which ask for file or directory names you are
allowed to use the ~name construct to specify the login directory belonging
to "name", even if you don't have a shell which knows about that.  Questions
where this is allowed will be marked "(~name ok)".

cat <<EOH

Much effort has been expended to ensure that this shell script will run
on any Unix system.  If despite that it blows up on you, your best bet is
to edit Configure and run it again. Also, let me (lwall@jpl-devvax.jpl.nasa.gov)
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.

This installation script affects things in two ways: 1) it may do direct
variable substitutions on some of the files included in this kit, and
2) it builds a config.h file for inclusion in C programs.  You may edit
any of these files as the need arises after running this script.

If you make a mistake on a question, there is no easy way to back up to it
currently.  The easiest thing to do is to edit config.sh and rerun all the
SH files.  Configure will offer to let you do this before it runs the SH files.

They are not compatible!  You are probably running ksh on a non-USG system.
I'll have to use /bin/echo instead of the builtin, since Bourne shell doesn't
have echo built in and we may have to run some Bourne shell scripts.  That
means I'll have to use $ans to suppress newlines now.  Life is ridiculous.
