# The dist-3.0 package (which contains metaconfig) was posted in

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...]

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.

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.  Also, let me (davison@borland.com)
know how I blew it.  If you can't run Configure for some reason, you'll have to
generate a config.sh file by hand.

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'll have to use $echo instead of the builtin, since Bourne shell doesn't
have echo built in and we may have to run some Bourne shell scripts.  That
means I'll have to use '$n$c' to suppress newlines now.  Life is ridiculous.

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

On some systems, mostly newer Unix System V'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.

into the "From" line of news articles posted from this machine.  If you
get this wrong the ownership checks done for Cancel, Supersede and
auto-post-selection (the -p option) will fail to recognize articles as
belonging to the poster.

(NOTE: trn does NOT create "From" lines when posting news or sending mail
as this is the job of your news/mail software, not trn.)

If you enter a filename here (by starting the name with '/' or '~') trn
will read the hostname from a file, otherwise specify as much of the
hostname as you want to be matched in the aforementioned comparisons.
If your response contains the current machine's name ($thishost) trn

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

use magic cookies like control codes between articles, so one of those
would be first.
