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

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 you, your best bet is
to edit Configure and run it again. Also, let the Elm Development Group
(elm@dsi.com) know how they 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, 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.

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 /bin/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 $ans to suppress newlines now.  Life is ridiculous.

There is a neat feature that enables scanning of the message body for
entries to add to the users ".calendar" (or whatever) file.  These
entries are then processed by the system program calendar.  To use
this feature it needs to be enabled.  The name of the per user calendar
file used by your system's calendar program is also required.

: check to see if the macros are 8-bit clean, ask the user
:
$cat <<EOM


Not all environments are restricted to the ASCII 7-bit character set.
For example, the ISO 8859/1 (Latin alphabet no. 1) character set,
consisting of 8 bits and 191 printable characters, is becoming
more and more common, especially in non-English speaking countries.

Unfortunately, not all isprint() functions or macros, which ELM
uses to determine whether a character is printable or not, will
handle non-ASCII (8-bit) characters properly.  It is suggested that you
start with this value configured to handle 8-bit characters correctly
and if there are problems with Elm aborting while displaying messages
that use extended character sets to reconfigure Elm to only display
7-bit characters.

If you wish to force everything to one memory model, say "none" here and

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.

Mail Transport Agents (sendmail, etc.) and Mail User Agents (Elm) can
use a variety of file locking protocols.  Based on your system type,
usage of a network, and MTA/MUAs in use, you may want to configure more
than one of the following Mail Locking Protocols.  It is recommended
that you use as many as are possible on your system to avoid problems.
All systems can support the dot locking method (.lock files).

Available locking protocols:
	dot locking (.lock)

On some systems, flock style locking and fcntl style locking use the
same underlying calls so both are not only not necessary, but may
interfere with each other.  On other systems they are distinct and both
should be used.  You will have to consult the documentation for your
operating system to determine in which class your system resides.

: determine whether MIME messages should be passed to metamail
: also select default sending and display charcter sets


$cat <<EOM

Elm supports the RFC-1521 Multipurpose Internet Mail Extensions (MIME).
MIME allows you to use international character sets (not just US-ASCII)
in mail messages.  MIME also allows multiple objects (binaries,
graphics, audio, video, PostScript, spreadsheets -- whatever!) to be
attached to mail messages.  MIME does not require a graphic display,
but some of its neatest capabilities demand one.

Elm generates MIME messages on its own.  To handle incoming MIME
messages, however, you need to install Nathaniel Borenstein's "metamail"
package on your system.  The most recent version of "metamail" is
distributed from thumper.bellcore.com [128.96.41.1].  Additional
distribution points are available; consult an "archie" server.

You may choose to have Elm pass received MIME messages to "metamail".
Otherwise, if you do not have "metamail" (or you elect not to use
it), Elm can ignore the MIME attributes and display the message as-is.

cat <<EOM

When composing outbound mail messages, Elm checks whether there are
any 8-bit "international" characters in the message.  If not, the
message is labelled as "us-ascii".  If there are, Elm needs to specify
the character set for the message.  What international character set
do people on your system most commonly use?  "iso-8859-1" is a common
selection, and is appropriate for many European languages.  (The choice
you make here becomes the system default.  Users that want a different
choice may set an "elmrc" value.)

When a message is received, Elm needs to know whether the terminal
can display the characters in the message, or if it needs to start up
"metamail".  What character set does your terminals most commonly
handle?  "iso-8859-1" is a common selection, and is appropriate for
many European languages.  (Even VT-100 text terminals can do this.)
If your displays have no capability whatsoever, then select "us-ascii".

a different choice may set an "elmrc" value.)

: get remove at last flag and number of lock attempts
$cat <<EOM

The next pair of questions have to do with what to do when another
program has locked a mailbox...

First, how many times should the Elm check for the removal of the lock
file before giving up?

Some sites that install the Elm Mail System may not wish to enable the
S)tatus Change function, which permits users to change the status of
their messages arbitrarily from within Elm.  If you choose, you can
instead disable that function, with the program being slightly smaller
and presenting an appropriate error message to users if they try to
invoke S)tatus Change to alter the status of their messages.

Some sites wish to disable the usage of the shell escape from Elm.
If you choose, you can disallow subshells from within Elm.

WARNING: This only controls Elm's usage of the ! command.  Any pager
or editor could still allow subshells.  It is also trivial to get a
subshell through manipulation of the pipe command or various option
settings.  DO NOT rely on this as a security measure.

One of the more annoying quirks of the UUCP network and various other
systems that interact with it are that everyone seems to have different
ideas about how to do routing, etc.  Therefore, a lot of times e-mail
will arrive from off site with corrupt, unusable "Reply-To:" and "From:"
fields.  This next question relates to whether your site is liable to
get mangled fields or not...

Does your site receive e-mail with valid "Reply-To:" and "From:" fields?

The getdomainname system call was found.  When running NIS, this usually
returns the NIS domain and not the mail domain.  If this is the case,
it should not be used to obtain the domain name, and the domain name
should be compiled into the code, and the global elm.rc file should
be used to override the compiled in value.

If the getdomainname call does return the correct mail domain, it can
be used.

cat <<EOM

Elm needs to be installed and run as a setgid program only if the mail
spool directory permissions do not allow world write access.  If your
mail spool directory has the permissions:

drwxrwxr-x  3 root     mail          512 Dec 24 17:20 /usr/mail

then Elm must be setgid to the same group as the mail spool directory
(in this case group mail).  However, if the spool permissions look
like:

drwxrwsrwt  2 root     staff         512 Dec 21 20:14 /usr/spool/mail

then Elm should not be installed or run as a setgid program.

    mailermode=2755
    cat <<EOM

Since Elm is being installed as a setgid program, it must be installed
by root, or a user able to set the setgid bit.

To provide better security, Elm can be configured to switch to the
privileged group of $mailgrp only when necessary to access mail folders.

Unfortunately, not all machines can switch between the real and effective 
gid values.  If you are not sure of the capability of your machine, it
is suggested that you start with Elm configured to switch gid values and
if, when you run Elm it cannot set the lock for the mailbox, reconfigure
Elm to not use this feature.
