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.
X
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)".
X
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 Davison how he blew it
X([e-mail]).
X
This installation script affects things by doing direct variable substitutions
on some of the files included in this kit. You may edit any of these files as
the need arises after running this script.

format files and normal files.  It does this by examining the first character
of the file in question.  On most systems the first line starts "From...",
so the first character is F.  On other systems there are magic cookies like
control codes between articles, so one of those would be first.  For example,
MMDF messages are separated with lines of 4 control-A's.  On your system, if a

Trrn determines the machine to use as a news server by two means:
X
XFirst:    It examines the environment variable NNTPSERVER for a machine name.
X    If present, this name is used in preference to the default.
X
XElse:    It uses the default machine name, which is either read from a file
X    or compiled into trn.
X
It is your choice whether you wish the default machine name to be read
from a file or specified directly.  To distinguish the two, a filename
must start with a slash or a tilde, and it must already exist with the
server name in it (it can contains comments (#) and blank lines also).
Any other answer is assumed to be a machine name.  If you use an alias
X(such as "news-server") you can use your nameserver to map the name to
the actual machine.

Mthreads needs to create some private files (like active2, and maybe active1
and mt.log, depending on your setup).  These can go in the same directory as
the private executables, as long as it is writable by whoever runs mthreads.
Otherwise, a good place to put them is in your thread file directory.  Where

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 "eunet".
X
The categories you will be asked are:
X
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"), asia, etc.
X
X(If you don't have a distribution prefix in any of these categories then
just hit return.)

NOTE: the V7 compiler may ignore some #undefs that trn uses.  If so, you will
get messages about redefining EXT.  Some V7 compilers also have difficulties
with #defines near buffer boundaries, so beware.  You may have to play with
the spacing in common.h.
