XThis installation shell script will examine your system and ask you questions
Xto determine how $package and any auxiliary files should be installed.  If you
Xget stuck on a question, you may use a ! shell escape to start a subshell or
Xexecute a command.  Many of the questions will have default answers in
Xsquare brackets--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)".

X
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.  (Trying to install this package
Xwithout having run Configure may be well nigh impossible.)  Also, let me
X(lwall@sdcrdcf.UUCP) know how I blew it.
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.
