# If these # comments don't work, trim them.  Don't worry about any other
# shell scripts, Configure will trim # comments from them for you.
#
# (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.)

# Yes, you may rip this off to use in other distribution packages.
# (Note: this Configure script was generated automatically.  Rather than
# working with this copy of Configure, you may wish to get metaconfig.)

ARGGGHHHH!!!!!

Your csh still thinks true is false.  Write to your vendor today and tell
them that next year Configure ought to "rm /bin/csh" unless they fix their
blasted shell. :-)

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 ([e-mail])
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.
