# Note: if you are running ksh, be sure to say "sh Configure".

# (If you are trying to port this package to a machine without sh, I would
# suggest you cut out the prototypical config.h from the end of Configure
# and edit it to reflect your system.  Some packages may include samples
# of config.h for certain machines, so you might look for one of those.)

cat <<EOH
 
This installation shell script will examine your system and ask you questions
to determine how $package and any auxiliary files 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.  (Trying to install this package
without having run Configure may be well nigh impossible.)  Also, let me
(lwall@sdcrdcf.UUCP) know how I blew it.

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.
