cat <<'EOH'
This installation shell script will examine your system and ask you questions
to determine how rn and its auxiliary files should be installed. If you
get stuck on a question, you can interrupt and start over without fear of
getting messed up. 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 rn without having run
Configure is well nigh impossible.) Also, let me (lwall@sdcrdcf.UUCP) know
that 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 config.h file for inclusion in C programs. You may edit
any of these files as the need arises after running this script.

Distribution groups are the things you use on the Distribution line to limit
where an article will go to. You are likely to be a member of several
distribution groups, such as organization, city, state, province, country,
continent, etc. For example, Los Angeles has the distribution prefix "la",
New Jersey has the prefix "nj", and Europe has the prefix "eur".
The categories you will be asked are:
local organization (Could be just one machine or a cluster or an office)
organization att, dec, kgb, ...
city la, ny, mosc, ...
state/province ca, nj, bc, ...
country usa, can, rok, whatever
continent na (North America, not "Not Applicable"), eur, etc.
(If you don't have a distribution prefix in any of these categories then
just hit return.)
