This installation shell script will examine your system and ask you questions
to determine how uumail and its 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)".

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 uumail without having
run Configure is well nigh impossible.)  Also, let me (sob@rice.edu) know
how I blew it.

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