This installation shell script will examine your system and ask you questions
to determine how trn 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 trn without having run
Configure is well nigh impossible.)  Also, tell Wayne ([e-mail])
how he 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 config.h file for inclusion in C programs.  You may edit
any of these files as the need arises after running this script.

I can set things up so that your shell scripts and binaries are more portable,
at what may be a noticable cost in performance.  In particular, if you
ask to be portable, the following happens:

     1) shell scripts will rely on the PATH variable rather than using
    the paths derived above.
     2) ~username interpretations will be done at run time rather than
    by Configure.
     3) the system name will be determined at run time, if at all possible.

Please enter your domain name.  This will be used in conjunction with the
site name for return addresses on news articles and mail.  If you use the
4.3ism of having your domain in your hostname, all the posting programs
will figure this out on the fly, so don't worry.

Examples of some valid domains:
    berkeley.edu
    nasa.gov
Example of an invalid domain in common use:
