Instructions for Installing MEP:
.sp 2
.NH 
Run the makefile.
.NH 
Put the following line in your .forward home in your home directory 
.sp 1
.LP
.nf
.nj
"|/fullpathnameforyou/youruserid/mep"
.sp 1
.NH 
Place mep in /pathname/youruserid/
.fi
.PP
Example:  Let us say your account is frob and the full path from root
(easily obtained by saying ~<return>) is /usr/acct/frob.
Compile the code above and place mep in /usr/acct/frob
.sp 1
.nf
	cd ~
	ls
	....files
	mep
.nf
.NH
Fix the .forward file
.sp 1
.LP
.nf
vi .forward

"|/usr/acct/frob/mep"
<esc>
:wq
.NH
Test
.fi
.PP
This is not the complete version of MEP.  It only support three of the
four functions in plan. twitlist, logging and @RR.
.nf
.NH 
Twitlist:
.PP
There are people you want mail from and people you DON'T want mail
from.  TwitMinder will handle that.  All twits will be discarded.
Merely place a file called .meptwits containing the userids (one/line)
in the file.  If the file is absent or empty, MEP will assume you
don't have any twits to worry about.  The format of the file is as
follows. pattern/op/[path]<return>  The pattern is the pattern to scan
for if the person is a twit, the op is a code of the type T,D, or S.
T = a twit.  Discard the mail, warn the user of the twit, exit. D =
Discard.  Discard this mail -- no questions asked.  S = Special.  This
mail is important.  If a path exists, forward mail on that path, biff
the user even if biff is off. ("Express mail has arrived")
.nf
.sp 1
bob/S/path!user
ralph/T/
MAILER-DAEMON/D/
root/S/
.sp 1
.fi
then if any of these people send you mail, that mail will be
discarded.  If you want to still be told that they tried, but don't
want to actually READ their mail, set the notify option in .meprc.
You can put a file .totwits in your home directory which will be sent
to twits whenever they send you mail.  This should be something nice,
but something which will make the point.  Mine is:
.br
.sp 1
Dear User
.br
.PP
We thank you for your mail but it is unnecessary at this time.
We will keep it on file for 60 days and let you know if something
opens up.

					Sincerely
.sp 1
					The Management
.sp 1
				HAVE A HAPPY DAY
.br
.sp 1
.fi
If this file is absent, no message will be sent.  NOTE:  You are
only allowed to have 100 twits.  If you have more,
contact me for a bigger version or so I can modify the code to
discard everyone BUT the people in the twitlist.
.nf
.sp 1
.NH
Configuration:
.sp 1
.LP
.nf 
A file .meprc contains commands used on startup.  They are:
.sp 1
stat=<file>/none
biff=<yes>/<no>
notify=<yes>/<no>
.sp 1
.fi
The first command specifies where you want the mail log to go.  
biff specifies whether you want the Unix BSD "biff" feaature active.
notify specifies whether you want to be notified if a twit  sends you
mail.  If this file is absent, the options are set as stat=none,
biff=no, notify=no.  Thus, a maillog will not be kept, you will NOT be
notified about TWITS or incoming mail.
.nf
.NH
Logging:
.PP
.fi
When this is set, all mail coming in will have a timestamp put into a
file at /pathname/filename.  (Usually just filename will do as it will
go into your home directory.)  Entries are:
.sp 1
.nf
From <path!user> @ Date/Time
From <path!user> @ Date/Time
...
.sp 1
The correct sytax is:

stat=<filename> where <filename> is path/name of logfile
stat=none	(Do NOT log mail)
.sp 1
.NH
 @RR:  This should be in column one.
.fi
.PP
This is a neat little feature which allows you ask someone who is
running this mailer (or for them to ask you) to mail you notification
that they received your mail.
Just include @RR at the begginning of a line by itself somewhere in
your mail to them.
.sp 1
.nf
Mail frob
Subject: Test
This is a  test
This is a new test
 @RR This should be in column one
This is a test
.
.sp 1
.fi
This will send them the mail above, but will also (because of @RR)
send you a notice that they received it. 
.nf
.NH 
 @SH line
.PP
This allows certain programs to be run by the mailer.  In your home
directory, there is a file .mepcmds.   In this file are the names
of programs which can be run. (One/line).
Example:
.nf
.sp 1
mep<return>
mydate<return>
etc.
.sp 1
.fi
You just can't issue shell commands, because something has to mail
the results back to you.  Notice the copy of mepmail as an example.
The line is the command line you are sending.  Remember, the program
will start the search in your $HOME directory.  If this file is empty
or missing, the system will not allow ANY commands via MEP.
