[ This is from the file "Overview..." --r$ ]
Currently on Unix, there seems to be a preponderence of line-oriented
software. This is most unfortunate as most of the software on Unix tends to
be pretty darn hard to use! I believe that there is more than a slight
correlation between the two, and, since I was myself having problems using
"mailx" with high-volume mail, I created a new mail system.
In the lingo of the mail guru, Elm is a "User Agent" system, it's
designed to run with "sendmail" or "/bin/rmail" (according to what's on
your system) and is a full replacement of programs like "/bin/mail" and
"mailx". The system is more than just a single program, however, and
includes programs like "frm" to list a 'table of contents' of your
mail, "printmail" to quickly paginate mail files (to allow 'clean'
printouts), and "autoreply", a systemwide daemon that can autoanswer
mail for people while they're on vacation without having multiple
copies spawned on the system.

XElm 2.2 release is the 2.2 Version being prepared for release.

XSee the NOTICE and Instruct files for further details.
X
XLimitations/Problems you might encounter in installing Elm:
X
XThe Configuration script has been known to exceed the default stack
Xsize in Unix 286 sh's. If Configure does not run correctly on this
Xtype of machine increase the stack size and rerun it.
XOn Microport SysV/AT machines, Configure will run correctly under
Xksh. Obtain ksh from Microport (available to current version owners
Xwithout additional charge) and rerun Configure using it.
X
XAlso on Microport SysV/AT Machines, the C compiler produces improper code
Xfor one of the arithmetic calls. To fix this problem it is necessary to
Xreduce the complexity of the statement, as reported by one of our testers
Xhere is the symptom and his patch. Being this is a compiler bug on only
Xone system, we make the information available, but not incorporate it in
Xthe main release. Note, this may effect other areas of Elm, and in the
Xfuture, Microport may even fix this problem.
X> I finally tracked down the bug that was causing the lengthy delays when
X> the first message was displayed. The Microport 80286 C compiler was
X> generating bad code for the computation of padding in showmsg.c. The
X> compiler generated scratch variables in the expression were being
X> located at weird offsets in the stack segment. This caused the program
X> to stall while the kernel attempted to grow the stack segment to a size
X> that was large enough to contain the scratch variables. This explains
X> why it only happened the first time a message was displayed. Here is a
X> patch that fixes the problem:

XIf you run a nonstandard configuration of Mail, such as Xenix running smail,
XConfigure can get confused as to where to place items. Be sure and check the
Xconfig.sh file for the correct placement before continuning. If changes
Xare necessary, rerun Configure and fix the file before exiting.
X
XOn some systems, especially those based on the AT&T Port to 286's
Xthe -O flag of the compiler produces improper code causing segmentation
Xviolations. If this happens, recompile the code without the -O flag.
XThis has been seen with Microport SysV/AT type systems.

X An Overview of the Elm Mail System
X ----------------------------------
X
XIntroduction
X
X This file discusses the functionality of the Elm mail system
Xand explains some of the motivation behind the various features.
X
X1. What is Elm?
X
X Currently on Unix, there seems to be a preponderence of line-oriented
Xsoftware. This is most unfortunate as most of the software on Unix tends to
Xbe pretty darn hard to use! I believe that there is more than a slight
Xcorrelation between the two, and, since I was myself having problems using
X"mailx" with high-volume mail, I created a new mail system.
X
X In the lingo of the mail guru, Elm is a "User Agent" system, it's
Xdesigned to run with "sendmail" or "/bin/rmail" (according to what's on
Xyour system) and is a full replacement of programs like "/bin/mail" and
X"mailx". The system is more than just a single program, however, and
Xincludes programs like "frm" to list a 'table of contents' of your
Xmail, "printmail" to quickly paginate mail files (to allow 'clean'
Xprintouts), and "autoreply", a systemwide daemon that can autoanswer
Xmail for people while they're on vacation without having multiple
Xcopies spawned on the system.
X
X2. What's New about Elm?
X
X The most significant difference between Elm and earlier mail
Xsystems is that Elm is screen-oriented. Upon further use, however,
Xusers will find that Elm is also quite a bit easier to use, and quite
Xa bit more "intelligent" about sending mail and so on. For example,
Xsay you're on "usenet" and receive a message from someone on the
XARPANET. The sender also "cc'd" another person on ARPA. With Elm
Xyou can simply G)roup reply and it will build the correct return
Xaddresses.
X
X There are lots of subtleties like that in the program, most of
Xwhich you'll probably find when you need them.
X
X3. What systems does it work on?
X
X Elm was originally written on HP-UX, HP's proprietary version
Xof Bell system V, with a little BSD thrown in. Since then, it has been
Xported to Bell, Berkeley, Sun, UTS, Pyramid and Xenix and should run on
Xall these systems without any modifications (if there turn out to be
Xmodifications, please notify the author as soon as possible).
X
X4. Does it obey existing mail standards?
X
X Yes! That's another of the basic reasons the program was
Xoriginally written! To ensure that the date field, the "From:" line
Xand so on were all added in the correct format. The program is 100%
Xcorrect according to the RFC-822 electronic mail header protocol
Xguide.
X
X5. What were the main motivating factors?
X
X The first two I've already mentioned, but here's a (somewhat
Xpartial) list;
X
X - To have a mail system that exploited the CRT instead of
X assuming I'm on a teletype.
X
X - To have a mailer that was 100% correct when dealing with
X network mail (ie RFC-822).
X
X - To create a system that needed no documentation for the
X casual user, but was still powerful enough and sophisticated
X enough for a mail expert.
X
X - To write a "significant" piece of software as a learning
X experience (I admit it!)
X
X - To find out how reasonable it is to try to modify a program
X to meet the expectations of the users, rather than vice-versa.
X
X - To basically correct some of the dumb things that the current
X mailers do, like letting you send mail to addresses that it
X could trivially figure out are going to result in 'dead.letter'
X
X - To tie in intimately with the pathalias program output, and
X allow users to specify machine!user or user@machine and have
X the COMPUTER do the work of figuring out addresses...
X
X6. Is it reliable?
X
X The mailer, in various incarnations, has logged literally
Xthousands upon thousands of hours without any problems that aren't
Xnow corrected. As new problems arise they're dealt with in as
Xrapid a manner as possible...
X
X7. Disclaimers
X
X The author of this program will deny all liability for any
Xdamages, either real or imagined, due to the execution of this program
Xor anything related to either the software or the system. Furthermore,
Xthe entire system and all source within, including the presentation
Xscreens and commands, are legally copyrighted by the author, and while
Xthey can be used, and abused, for public domain systems, it will be in
Xviolation of the law if used in systems or programs sold for profit.
X
X By installing the mailer or even extracting it from the network,
Xyou are agreeing to the above disclaimer.
X
X8. Finally
X
X I think it's a good program, and I can cite at least 75 people
Xwho would (begrudgingly, I'm sure) agree. You should most certainly
Xinstall the program and try it!!

X Instructions
X ------------
X
X Last Update: $Date: 89/03/23 16:15:01 $
X
X
X This file contains instructions on how to create and install
Xthe entire ELM mail system. It should be read BEFORE any attempts
Xare made at actually creating and/or installing any of the software
Xcontained herein!
X
X There is actually really one step needed - unpack all the shar
Xfiles and then;
X
X $ cd <where-ever you're keeping the Elm sources>
X
X $ sh Configure
X
X Answer the questions of that program,, then let it create the
Xlocalized Makefiles and system definition files for you. When it's
Xdone you can double check the configuration (or customize it further)
Xby reading the Configuration Guide and then rerunning Configure.
XThere are lots of neat features that are unique to this mailer - it's
Xworth a quick perusal at least!
X
X Once you're happy with the localized files, you then need to
Xcreate the documentation (so there's a bit of a catch-22 that you need
Xto format the Configuration guide before you are happy with the
Xlocalization but can't do that until you're happy with the
Xlocalization...oh well).
X
X $
X
X $ make documentation
X
X When that's done, or even if it fails (don't worry too much about
Xit), do the following:
X
X $ make all > MAKELOG 2>&1 &
X $ tail -f MAKELOG
X
X (if you're in "csh", substitute: "make all >& MAKELOG &")
X
XThis will take a fair while, so it's recommended that you go and eat
Xlunch or play a game for a while!! (alternatively, spend lots of money
Xon a really FAST machine and blink your eyes a few times...)
X
XAssuming there are no errors during compilation (we'll have to assume
Xthat for the moment) you should now be able to list the directory "bin"
Xand find the following files:
X
X answer checkalias filter messages printmail
X arepdaemon elm frm newalias readmsg
X autoreply fastmail listalais newmail
X
Xnext, you can install all the software on your system by;
X
X $ make install
X
XNote: the mailer runs as setgid mail to have the ability to WRITE
Xto the mail directory (for lock files). If you have a different
Xscheme at your site, feel free to set it up to use that instead.
X
XFinally, we're just about done! The final checks can be made
Xby the following commands:
X
X $ elm -z
X
Xshould say "no mail" if nothing's in your incoming mailbox or should
Xstart up the Elm program if there is, and
X
X $ elm -f test/test.mail
X
Xshould read in EIGHT messages from various people. While here, try to
XA)lias C)urrent message for each of the eight messages to confirm that
Xthe reply/address system is working okay. Now Q)uit without having
Xmarked anything for deletion...answer the questions accordingly.
X
XIf you get this far you're in wonderful shape! In fact, you're done!
X
XCongratulations! You've just installed one of the best electronic mail
Xsystems available today on your machine (if I say so myself!)
X
XHANDY HINTS: If you want to create a print of the entire set of
Xsources, including this file, use the command:
X
X $ make listing
X
XIf, on the other hand, you just want to create a listing file of
Xjust the Elm sources, try:
X
X $ make elm-listing
X
XAlso, if you have a number of machines on a network, you can rlogin
Xto the remote machine and then do a remote install (after checking
Xto ensure that the networking copy method in the Makefile under the
Xtarget "remote-install" is correct) by typing:
X
X $ make -f <remote Makefile> REMOTE=<remote file system> rmt-install
X
X(for example, if we had installed the system on machine "machx" and
X wanted to install it on "machy", with the Makefile in /src/Elm on
X "machx", we could type from "machy";
X $ make -f machx:/src/Elm/Makefile REMOTE=machx: rmt-install
X to have it install the system on machine y!)
X
XThat's it!

X************************************************************************
X* The 2.2 release is the result of many man-years of work by the
X Elm Development and Testing Groups. The changes are too many
X to mention in their entirity, as I doubt I could even track
X them all. However this file will attempt to highlight some of
X them.
X
X* Many of the changes are internal and not visible. These help
X to make Elm more robust and more maintainable. We still have a
X long way to go in this direction, but Elm 2.2 is a step in the
X right direction.
X
X* This is not a patch to 2.1, but a complete new release. Some
X file names have changed, so do NOT put this release in the same
X directory as the old one.
X
X* The first change is a complete rewrite of the Configuration
X system. We are now using Larry Walls metaconfigure package
X from his Dist V2.0 utilities. This should make configuration
X much easier, but also currently makes the configuration
X questions appear is a non optimum order.
X
X* The documentation has been rewritten from the mm macro set,
X which is distributed only with USG type systems, to a
X modification of the news macro set which is being distributed
X with Elm.
X
X* The interface to the internal and external pagers have been
X rewritten to reduce problems. The internal pager is still very
X dumb.
X
X* All system messages have been worked on to make them more
X consistent.
X
X* Numerious new elmrc options have been added.
X
X* The system wide alias file has been moved from the spool
X directory to the library directory.
X
X* Elm has been made more compatible with Mailx and Mush for sites
X that mix their usage. To this end a Quick quit command has
X been added as have Status headers.
X
X* The batch send mode and the send only mode within Elm has
X been changed to make it more consistent with the normal mode.
X
X* Much work has been done to make Elm's curses more compatible
X with more terminal types. However this is an interim
X solution. Long term plans are to scrap the internal curses and
X use the system curses.
X
X* The meaning of the space bar has been changed to allow one to
X page through their entire mailbox using the space bar.
X
X* A copy command has been added, like the save command, but does
X not mark the message for deletion.
X
X* All headers are now saved to the mail archive file.
X
X* The alias menu now has the ability to list and delete aliases.

XThis installation shell script will examine your system and ask you questions

Xa command. Many of the questions will have default answers in square
Xbrackets--typing carriage return will give you the default.
X
XOn some of the questions which ask for file or directory names you are
Xallowed to use the ~name construct to specify the login directory belonging
Xto "name", even if you don't have a shell which knows about that. Questions
Xwhere this is allowed will be marked "(~name ok)".

Xknow how I blew it. If you can't run Configure for some reason, you'll have
Xto generate a config.sh file by hand.
X
XThis installation script affects things in two ways: 1) it may do direct
Xvariable substitutions on some of the files included in this kit, and
X2) it builds a config.h file for inclusion in C programs. You may edit
Xany of these files as the need arises after running this script.
X
XIf you make a mistake on a question, there is no easy way to back up to it
Xcurrently. The easiest thing to do is to edit config.sh and rerun all the
XSH files. Configure will offer to let you do this before it runs the SH files.
