XThis installation shell script will examine your system and ask you questions
Xto determine how the $package package should be installed.  If you get stuck
Xon a question, you may use a ! shell escape to start a subshell or execute
Xa command.  Many of the questions will have default answers in square
Xbrackets--typing carriage return will give you the default.
X
XOn some of the questions which ask for file or directory names you are
Xallowed to use the ~name construct to specify the login directory belonging
Xto "name", even if you don't have a shell which knows about that.  Questions
Xwhere this is allowed will be marked "(~name ok)".

XMuch effort has been expended to ensure that this shell script will run
Xon any Unix system.  If despite that it blows up on you, your best bet is
Xto edit Configure and run it again. Also, let me (paul@devon.lns.pa.us)
Xknow how I blew it.  If you can't run Configure for some reason, you'll have
Xto generate a config.sh file by hand.
X
XThis installation script affects things in two ways: 1) it may do direct
Xvariable substitutions on some of the files included in this kit, and
X2) it builds a config.h file for inclusion in C programs.  You may edit
Xany of these files as the need arises after running this script.
X
XIf you make a mistake on a question, there is no easy way to back up to it
Xcurrently.  The easiest thing to do is to edit config.sh and rerun all the
XSH files.  Configure will offer to let you do this before it runs the SH files.
