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.sh X X Answer the questions of that program,, then let it create the localized XMakefiles and system definition files for you. When it's done you can double Xcheck the configuration (or customize it further) by reading the Configuration XGuide + editing the file "hdrs/sysdefs.h". There are lots of neat features Xthat are unique to this mailer - it's worth a quick perusal at least! X X Once you're happy with the localized files, you then need to create Xthe documentation (so there's a bit of a catch-22 that you need to format the XConfiguration guide before you are happy with the localization but can't do Xthat until you're happy with the localization...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 it) X X $ (make -i all >& MAKELOG) & X $ tail -f MAKELOG X X (if you're in "sh", you can use "> MAKELOG 2>&1" instead of ">& 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", "arepdaemon", "autoreply", "fastmail", "from", X "elm", "newalias", "newmail", "printmail", and "readmsg". X Xnext, you can install all the software on your system by; X X $ make -i install X XNote: the mailer runs as setgid mail to have the ability to WRITE Xto the /usr/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 $ /usr/local/bin/elm -z X Xshould say "no mail" if nothing's in your incoming mailbox, and X X $ /usr/local/bin/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 try to C)hange mailboxes Xto the file "test/test.note" and use the '%' key to see if the mailer is Xgenerating valid return addresses for the notes (If not, then you might Xneed to install the pathalias database - see "sysdefs.h" for more info) XChange back to "test/test.mail" and Q)uit without having marked anything Xfor 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 XOne final note for non-US distribution - the program might complain Xat link time that it can't find "crypt()". If so, and if you cannot Xobtain a copy, you should merely instruct your users to not use the Xencrypted mail option on outgoing mail. X XThat's it! X---------- X XOh! One final note: if you'd like a nicely typeset copy of the documentation, Xfeel free to drop me a line with your full (overland) mail address!! I'll Xtry to get it back to you within a week or two.
