# If these # comments don't work, trim them. Don't worry about any other
# shell scripts, Configure will trim # comments from them for you.
#
# (If you are trying to port this package to a machine without sh,
# I would suggest you have a look at the prototypical config_h.SH file
# and edit it to reflect your system. Some packages may include samples
# of config.h for certain machines, so you might look for one of those.)
#
# Yes, you may rip this off to use in other distribution packages. This
# script belongs to the public domain and cannot be copyrighted.
#
# (Note: this Configure script was generated automatically. Rather than
# working with this copy of Configure, you may wish to get metaconfig.
# The dist-3.0 package (which contains metaconfig) was posted in
# comp.sources.misc and is available on CPAN under authors/id/RAM so
# you may fetch it yourself from your nearest archive site.)

ARGGGHHHH!!!!!

SCO csh still thinks true is false.  Write to SCO today and tell them that next
year Configure ought to "rm /bin/csh" unless they fix their blasted shell. :-)

(Actually, Configure ought to just patch csh in place.  Hmm.  Hmmmmm.  All
we'd have to do is go in and swap the && and || tokens, wherever they are.)

[End of diatribe. We now return you to your regularly scheduled programming...]

OOPS!  You naughty creature!  You didn't run Configure with sh!
I will attempt to remedy the situation by running sh for you...

This installation shell script will examine your system and ask you questions
to determine how the trn package 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)".

EOH
	rp=''
	dflt='Type carriage return to continue'
	. ./myread
	cat <<'EOH'

The prompter used in this script allows you to use shell variables and
backticks in your answers.  You may use $1, $2, etc...  to refer to the words
in the default answer, as if the default line was a set of arguments given to a
script shell.  This means you may also use $* to repeat the whole default line,
so you do not have to re-type everything to add something to the default.

Everytime there is a substitution, you will have to confirm.  If there is an
error (e.g. an unmatched backtick), the default answer will remain unchanged
and you will be prompted again.

If you are in a hurry, you may run 'Configure -d'.  This will bypass nearly all
the questions and use the computed defaults (or the previous answers if there
was already a config.sh file). Type 'Configure -h' for a list of options.
You may also start interactively and then answer '& -d' at any prompt to turn
on the non-interactive behaviour for the remainder of the execution.

EOH
	. ./myread
	cat <<EOH

Much effort has been expended to ensure that this shell script will run on any
Unix system.  If despite that it blows up on yours, your best bet is to edit
Configure and run it again.  If you can't run Configure for some reason,
you'll have to generate a config.sh file by hand.  Whatever problems you
have, let me (trn-workers@lists.sourceforge.net) know how I blew it.

This installation script affects things in two ways:

1) it may do direct variable substitutions on some of the files included
   in this kit.
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.

If you make a mistake on a question, there is no easy way to back up to it
currently.  The easiest thing to do is to edit config.sh and rerun all the SH
files.  Configure will offer to let you do this before it runs the SH files.

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.

If you want to be able to post articles to multiple servers, you should
install the inews that comes with $package.  You can either put inews into
a public spot for all newsreaders to use (recommended) or put it into a
private spot for just $package to use.  This enhanced inews knows how to
post to the current remote server and how to hand off an article to a
local-posting inews, as appropriate.  An additional benefit is that this
inews can share the same NNTP connection that the newsreader is using
instead of opening a new one.

In summary, a good installation would be to put $package's inews into
a public spot (e.g. /usr/local/bin) and, if you have a local news spool,
have it use a private copy of your news server's inews as a resource
(in a place such as /usr/lib/news).  If you don't want this enhanced
inews installed, answer "none".

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 code "la",
New Jersey has the code "nj", and Europe has the code "eunet".

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, ...
multi-state region	pnw, ne, ...
country			usa, can, rok, whatever

Some versions of Unix support shared libraries, which make executables smaller
but make load time slightly longer.

On some systems, mostly System V Release 3's, the shared library is included
by putting the option "-lc_s" as the last thing on the cc command line when
linking.  Other systems use shared libraries by default.  There may be other
libraries needed to compile $package on your machine as well.  If your system
needs the "-lc_s" option, include it here.  Include any other special libraries
here as well.  Say "none" for none.

I can use $nm to extract the symbols from your C libraries. This
is a time consuming task which may generate huge output on the disk (up
to 3 megabytes) but that should make the symbols extraction faster. The
alternative is to skip the 'nm' extraction part and to compile a small
test program instead to determine whether each symbol is present. If
you have a fast C compiler and/or if your 'nm' output cannot be parsed,
this may be the best solution.

You probably shouldn't let me use 'nm' if you are using the GNU C Library.

In saving articles, $package wants to differentiate between saving to
mailbox 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 with "From ...", so the first character is an F.  Other systems
use magic cookies like control codes between articles, so one of those
would be first.  For example, MMDF messages are separated with lines of
four control-A's (you may specify one as ^A, i.e. caret A).
