+This file explains how to build and install Zephyr on a machine.  To
+learn how to use Zephyr once you've installed it, read the file USING.
+To learn how to set up Zephyr service at a site, read the file
+OPERATING.
+
+To build and install Zephyr, run:
+
+	./configure
+	make
+	make install
+
+This will build Zephyr without Hesiod or Kerberos support, and install
+in /usr/local.  To install in a location other than /usr/local, add
+"--prefix=INSTPREFIX" to the configure line, where INSTPREFIX is the
+directory you want to install Zephyr in.
+
+If your site has a Hesiod service with a valid zephyr.sloc entry (or
+you can add one), you can enable Hesiod support by adding the option
+"--with-hesiod=HESPREFIX" to the configure line, where
+HESPREFIX/include and HESPREFIX/lib are the directories you have the
+Hesiod libraries installed in.
+
+If your site has a Kerberos 5 service, you can enable Kerberos 5 support
+by adding the option "--with-krb5=KRBPREFIX" to the configure line,
+where KRBPREFIX/include and KRBPREFIX/lib are the directories you
+have the Kerberos libraries installed in.
+
+If your site has a Kerberos 4 service, you can enable Kerberos 4 support
+by adding the option "--with-krb4=KRBPREFIX" to the configure line,
+where KRBPREFIX/include and KRBPREFIX/lib are the directories you
+have the Kerberos libraries installed in.  Note that this is
+deprecated, and should only be enabled for transitions.
+
+If you build with both krb5 and krb4, you will get a client that only
+knows how to authenticate with krb5 servers, but a server that can
+understand authentication from both krb4 and krb5 clients.
+
+If you want/need a krb4 client, you have to build without krb5.
+
+If you have a make which supports VPATH in a manner compatible with
+GNU make, you can build in a separate directory.  Simply invoke the
+configure script from within the build directory and configure will
+locate the source directory for you.  (If that doesn't work for some
+reason, you can also specify "--srcdir=SOURCEDIR" on the configuration
+line.)
+
+If configure can't properly find your X11 include or library
+directories, add "--x-includes=INCDIR" and "--x-libraries=LIBDIR" to
+the configure line.  To build without X11 support, add "--without-x"
+to the configure line.
+
+If you have Hesiod and/or Kerberos installed such that you can't
+specify a single prefix for both include files and libraries, set the
+environment variables CPPFLAGS and LDFLAGS to include the relevant
+directories, and just configure with "--with-krb4" and
+"--with-hesiod".  For instance (for a csh-like shell):
+
+	setenv CPPFLAGS "-I/opt/athena/include"
+	setenv LDFLAGS "-I/opt/athena/arch/sparc/lib"
+	./configure --with-hesiod --with-krb4
+	make
+	make install
+
+Although it's not necessary for Zephyr to function correctly, you
+should add the following services to /etc/services if possible:
+
+zephyr-clt      2103/udp                        # Zephyr serv-hm connection
+zephyr-hm       2104/udp                        # Zephyr hostmanager
+zephyr-hm-srv	2105/udp			# Zephyr hm-serv connection
+
+To learn how to use Zephyr, read the file USING and the man pages for
+the various Zephyr programs.  To learn how to operate a Zephyr
+service, read the file OPERATING.
+
+We have tried to make Zephyr as portable as is reasonably possible,
+but have not taken into account every possible kind of system.  If you
+have any problems building or installing Zephyr according to these
+instructions, please go to http://zephyr.1ts.org and open a ticket.

+Please observe the following notes when making changes to the source
+tree.
+
+The directory h contains header files used internally in the zephyr
+source tree.  The directory h/zephyr contains header files containing
+declarations for the Zephyr API.  h/zephyr/zephyr_err.h is generated
+from lib/zephyr/zephyr_err.et when lib/zephyr is built.
+h/zephyr/zephyr.h is generated by configure, as is h/config.h.  Those
+header files live in the build tree.  All other header files in h live
+in the source tree.
+
+h/config.h is generated by configure and contains the results of
+configure tests as well as definitions for the installation
+configuration directory and data directory.  h/sysdep.h uses
+h/config.h to include various header files or make various external
+declarations which many programs might be interested in.  h/internal.h
+contains declarations internal to the "Zephyr system proper," which
+includes the Zephyr library, the server, the hostmanager, and (for
+now) zstat.
+
+h/zephyr/zephyr.h is a public header file; that is, it is installed
+with the Zephyr system.  As such, this header file may need to work
+with compilers other than the compiler used to build the Zephyr system
+itself.  Thus, we use __STDC__ (both in h/sysdep.h and in zephyr.h) to
+guess whether the compiler will handle const, prototypes, and stdarg.
+This is unfortunately not as reliable as using autoconf features like
+AC_C_CONST.

+This file explains how to operate a Zephyr service once you have
+installed Zephyr on all the relevant machines and file servers in your
+environment.  To learn how to configure, build, and install Zephyr,
+read the file INSTALL.
+
+To set up Zephyr service at a site, follow these steps:
+
+1. Choose the machines you wish to have act as Zephyr servers at your
+site.  Expect the server to be CPU-efficient but to consume a bit more
+memory than you might expect (at MIT, with around a thousand
+simultaneous users, the Zephyr server's data size is 40MB).  If you
+have a lot of users, the server should have enough memory so that the
+process doesn't swap.
+
+2a. If you configured Zephyr with Hesiod support, make sure your
+Hesiod realm has a "zephyr.sloc" entry containing a record for each
+server.  (Each entry should contain the name of the server, nothing
+else.)  The Zephyr servers will use the zephyr.sloc entry to find the
+other servers.  Host managers will use the zephyr.sloc entry to find
+the Zephyr servers by default; however, you can control the set of
+servers for each host manager by giving each host a
+"<hostname>.cluster" entry containing a record "zcluster <serverset>".
+If such a record is found, the host manager will resolve
+"<serverset>.sloc" instead of "zephyr.sloc".
+
+2b. If you configured Zephyr without Hesiod support, and you have
+multiple Zephyr servers, each server should have a file "server.list"
+in the configuration directory (which is /etc/athena/zephyr if you
+configured with --enable-athena, or /usr/local/etc/zephyr if you
+installed Zephyr in /usr/local and didn't use --enable-athena).  This
+file should contain a list of the servers, one per line.  The server
+will read and use this file if it exists even if the server was built
+with hesiod support.
+
+3. If you configured Zephyr with Kerberos 5 support, make a service
+key "zephyr/zephyr@<your realm>" and install a keytab for that service
+as "krb5.keytab" in the configuration directory of each of your zephyr
+servers.  Note that you need to ktadd the keytab only once and copy it
+around; the files on all the servers should be identical.
+
+4. Start zephyrd from the system binary directory (/usr/athena/etc if
+you configured with --enable-athena, /usr/local/sbin if you installed
+in /usr/local and didn't use --enable-athena).  zephyrd logs as
+service "local6"; watch the syslogs for error messages.  Arrange for
+zephyrd to be run at boot time on your server machines.
+
+5. Each client machine should run zhm (the Zephyr Host Manager) from
+the local system binary directory (/etc/athena for --enable-athena,
+/usr/local/sbin if you installed in /usr/local and didn't use
+--enable-athena).  If you built Zephyr without Hesiod support, you
+should start zhm as "zhm server1 server2 server3 ..." so that zhm
+knows where the Zephyr servers are.  Do not use "localhost" or
+"127.0.0.1" as a server name, or zhm will become confused.
+
+You can send a SIGFPE signal to the server process to make it dump its
+subscription database to /var/tmp/zephyr.db.  (If /var/tmp didn't
+exist when Zephyr was built, the subscription database will be dumped
+in /usr/tmp or /tmp instead.)

+This is version @VERSION@ of the Project Athena Zephyr
+notification system.
+
+Zephyr allows users to send messages to other users or to groups of
+users.  Users can view incoming Zephyr messages as windowgrams
+(transient X windows) or as text on a terminal. Zephyr can optionally
+make use of the Kerberos version 4 security library or the Hesiod
+service name resolution library.

+This file explains how to use an existing Zephyr service once you've
+built and installed the Zephyr distribution.  To learn how to build
+and install Zephyr, read the file INSTALL.  To learn how to set up
+Zephyr service at a site, read the file OPERATING.
+
+First, before you can do anything else, your client machine must be
+running zhm from the local system binary directory (/etc/athena/zephyr
+if you built Zephyr with --enable-athena, /usr/local/sbin/zephyr if
+you installed Zephyr in /usr/local and didn't use --enable-athena).
+Only one copy of zhm can be running on a given machine, and it can be
+started by any user.  If you're using a machine you don't administer,
+you may want to check if the machine is configured to start up zhm
+automatically at boot time.
+
+Once you have zhm running, you can start receiving zephyrgrams by
+running the command:
+
+	zwgc
+
+"zwgc" stands for "Zephyr WindowGram Client".  If you built Zephyr
+with X support and are using an X display, you will receive messages
+as windows on your screen (click on them to get rid of them);
+otherwise, you will receive messages in your terminal as text.  Read
+the man page on zwgc to find out how to configure it using the
+.zwgc.desc file in your home directory.
+
+You can send messages to another user with:
+
+	zwrite username
+
+To write to groups of users, you must agree on a "class" and/or
+"instance" to write to (this will be explained in greater detail
+below).  At MIT, most users communicate in private groups via classes.
+Suppose a bunch of people wanted to communicate on a class "newclass".
+They would all subscribe to the class with the command:
+
+	zctl add newclass \* \*
+
+and send messages with:
+
+	zwrite -c newclass
+
+The "zctl add" command adds the subscription to the .zephyr.subs file
+in your home directory, so that you will automatically be subscribed
+to the class the next time you run zwgc.  If you just want to
+subscribe without adding the subscription to your .zephyr.subs file,
+use "zctl sub" instead of "zctl add".
+
+Now for a bit more explanation about what classes and instances are:
+every Zephyr message is send to a class, an instance, and a recipient,
+commonly written as <class,instance,recipient>.  The default class is
+"MESSAGE"; the default instance is "PERSONAL".  When you use "zwrite
+username", you are sending a message to <MESSAGE,PERSONAL,username>.
+If you don't specify a username on the zwrite command line, you will
+be sending to the recipient "*", so when you use "zwrite -c newclass",
+you are sending a message to <newclass,PERSONAL,*>.
+
+Similarly, every time you request a subscription, you are subscribing
+to a class, an instance, and a recipient.  The recipient must be
+either "*" or your username.  The instance can be any string; however,
+if you subscribe to instance "*", you will receive messages to any
+instance as long as the class and recipient also match.  The class can
+be any string; "*" has no special meaning for class names.  When you
+start zwgc, you are automatically subscribed to
+<MESSAGE,PERSONAL,yourusername> and <MESSAGE,URGENT,yourusername> even
+if you don't explicitly request those subscriptions.
+
+As an example of how you might use these features, at MIT we have
+several frequently-used instances of class MESSAGE, called
+"white-magic", "help", "weather", "tmbg" and so forth.  These are
+commonly known as "public" instances because they are not intended to
+exclude anyone.  Users can subscribe to individual instances using
+"zctl add message help \*", or they can subscribe to all of them at
+once using "zctl add message \* \*".  (If users do this, they can tell
+zwgc to filter out messages from certain instances; see the man page
+for zwgc.)  If users want to have semi-private group conversations,
+they use separate classes, as described earlier.

+.SH NAME
+zaway \- tell other people via Zephyr that you aren't around
+.SH SYNOPSIS
+.B zaway
+[
+.I OPTIONS
+]
+[
+.I FILE
+]
+.SH DESCRIPTION
+.I zaway
+provides a way for you to automatically send replies when other people
+contact you using
+.I zwrite(1). zaway
+subscribes itself to class "MESSAGE", instance "*", so that it can
+monitor your incoming messages.  It does not affect the operation of any
+other client receiving messages.
+.I zaway
+is typically run when you are leaving your terminal or display
+temporarily.
+.I zaway
+usually never exits; when you return to your terminal you should type
+the interrupt character (usually ^C) in order to make
+.I zaway
+exit.
+.SS OPTIONS
+.TP
+.I "\-m STRING"
+Use STRING as the body of the auto-reply message.  Any message file
+(specified on the command line or the default) is ignored.
+.TP
+.I "\-w"
+Watch the invoking user's location status.  If the user is locatable
+anywhere, no auto-replies will be sent.
+.TP
+.I "\-h"
+Displays a short usage message and exits.
+.PP
+.I zaway
+uses a message file (which defaults
+to $HOME/.away) to describe what reponses should be sent to which
+senders.  The general format of this file
+is:
+.PP
+.nf
+	>name
+	>name
+	message
+	>name
+	message
+.fi
+.PP
+Any number of user names may be specified preceding the message to send
+to those senders.  If a user name appears more than once, the message will
+be a concatenation of each of the appropriate messages.  There are
+two special names: "*" indicates that the following message should be
+sent to all senders and "%" indicates that the following message should
+only be sent if the user name has not matched yet. 
+.PP
+If no file is specified,
+and no default file can be found, the following message is returned:
+.sp
+.in +5
+I'm sorry, but I am currently away from the terminal and am
+not able to receive your message.
+.in -5
+.sp
+If a user name does not match any of those listed in the file, and no
+"*" or "%" field is specified, no return message is sent.  All
+messages are preceded by a signature "Automated reply:".  To avoid
+loops, messages are not sent in response to messages beginning with an
+"Automated reply:" signature or sent by the same Kerberos principal as
+the user running
+.I zaway.
+
+.SH SAMPLE FILE
+.nf
+>eichin
+>tony
+Hi there guys!  I'm in the other room right now.
+I'll be back in 5 minutes or so.
+>jruser
+Sorry, but I'm gone for the day...
+>%
+Hello...I'm not sure who you are.  I'll be back soon,
+though.
+>*
+This message comes to you compliments of zaway!
+.fi
+
+The final "compliments" message will be included in all messages,
+whereas the "I'm not sure" message will only be included in messages that
+are not from "eichin", "tony", or "jruser".

+.SH NAME
+zctl \- zephyr control program
+.SH SYNOPSIS
+.B zctl
+[
+.I options
+]
+.SH DESCRIPTION
+.I Zctl
+is a general purpose control program for the
+.I Zephyr(1)
+Notification Service.  It allows the user to subscribe to specific
+notice types, to save the subscriptions in a file (default
+$HOME/.zephyr.subs), to change his location information, and to send
+control messages to the HostManager,
+.I zhm(8),
+and the WindowGram client,
+.I zwgc(1).
+.PP
+The commands may be typed on the command line, or may be entered
+interactively by just typing
+.I zctl
+and then typing commands to the prompt.
+.br
+.B NOTE:
+For all commands accepting an optional \fIrecipient\fR argument, the
+\fIrecipient\fR defaults to your Kerberos principal.  You may also
+subscribe to recipient ``\fI*\fR''.  If you specify a recipient, it is
+silently converted to ``\fI*\fR''.
+.br
+The commands are as follows:
+.TP 15
+.B add \fIclass instance\fR [ \fIrecipient\fR ]
+Subscribe to \fIclass, instance, recipient\fR, and add this triplet to
+the subscriptions file.
+.TP
+.B add_unsubscription \fIclass instance\fR [ \fIrecipient\fR ]
+Unsubscribe to \fIclass, instance, recipient\fR, and add this triplet
+to the subscriptions file as an un-subscription.
+For an explanation of un-subscriptions, see below.
+.TP
+.B cancel
+Cancel all subscriptions.
+.TP
+.B defaults
+Retrieve the default subscription list from the Zephyr server.
+.TP
+.B delete \fIclass instance\fR [ \fIrecipient\fR ]
+Unsubscribe to \fIclass, instance, recipient\fR, and remove this triplet
+from the subscriptions file.
+.TP
+.B delete_unsubscription \fIclass instance\fR [ \fIrecipient\fR ]
+Unsubscribe to \fIclass, instance, recipient\fR, and remove this triplet
+from the subscriptions file as an un-subscription.
+.TP
+.B file \fR[ \fIfile\fR ]
+Set default subscriptions file to \fIfile\fR.  If \fIfile\fR isn't specified,
+show what the current subscriptions file is.
+.TP
+.B flush_locs \fR[ \fIuser\fR ]
+Tell the Zephyr servers to flush all location information associated with
+\fIuser\fR, or with the user running the command if none is given.  This
+should only be used to remove any incorrect data that may have been left
+after a system crash.  Note that only Operations staff may flush location
+information associated with another user.
+.TP
+.B flush_subs \fR[ \fIrecipient\fR ]
+Tell the Zephyr servers to flush all of \fIrecipient\fR's subscriptions,
+This differs from the cancel command in that it affects subscriptions for
+all of \fIrecipient\fR's clients.  Note that only Operations staff may flush
+the subscriptions of another user.
+.TP
+.B hide
+Hide your location as maintained by the Zephyr server.  This does not
+affect the value of the exposure variable (see below, under
+.B set).
+.TP
+.B hm_flush
+Tell the HostManager,
+.I zhm(8),
+to ask the server to flush all state associated with the current host.
+.TP
+.B list \fR[ \fIfile\fR ]
+List contents of current subscriptions file or
+.I file.
+Any macros in the file (see below) are displayed verbatim and not expanded.
+.TP
+.B list_requests
+List all available commands.  May be abbreviated by '?'.
+.TP
+.B load \fR[ \fIfile\fR ]
+Subscribe to all subscription triplets and unsubscribe to all
+un-subscription triplets in current subscriptions file or \fIfile\fR.
+.TP
+.B new_server
+Tell the HostManager,
+.I zhm(8),
+to find a new Zephyr server.
+.TP
+.B quit
+Exit from \fIzctl.
+.TP
+.B retrieve
+Retrieve all current subscriptions from the Zephyr server.  These include
+subscriptions that might have been made by other programs, such as
+.I znol(1).
+.TP
+.B save \fR[ \fIfile\fR ]
+Save all current subscriptions (as returned by the Zephyr server)
+into current subscriptions file or \fIfile\fR.  The 
+file will be replaced.
+.TP
+.B set \fIvar\fR [ \fIvalue\fR ]
+Set the value of Zephyr variable \fIvar\fR to \fIvalue\fR, or null if
+no \fIvalue\fR is specified.  The variable \fBexposure\fR has special
+significance, and can only be set to the values none, opstaff, realm-visible,
+realm-announced, net-visible, and net-announced.  Setting this variable
+immediately updates the information in the Zephyr servers (see below for
+an explanation of the exposure levels).  In addition,
+setting this variable to none automatically performs the equivalent of a 
+.B wg_shutdown
+command, and setting it to one of the other values automatically
+performs the equivalent of a 
+.B wg_startup
+command.
+.br
+The variable \fBresolved_addresses\fR determines whether zwgc will,
+for an IP address indicating the origin of a message, attempt to look
+up the hostname corresponding to that IP address. The value none
+indicates that hostnames will never be found, and that the zwgc
+fromhost variable will thus always contain an IP address (in
+dotted-decimal form). The value all indicates that there will always
+be an attempt to look up a hostname. Note that in this case, if you
+have any subscriptions with recipient ``\fI*\fR'', these subscriptions
+may be revealed to other Zephyr users who operate their own DNS name
+servers. Any other value is interpreted as a regular expression;
+hostname lookup attempts will occur only if the IP address matches
+this regular expression.
+.br
+Any variable settings you make will be stored in \fI$HOME/.zephyr.vars\fR
+.TP
+.B show \fIvar\fR [ \fIvar\fR \ ... ]
+Show the value of the specified Zephyr variables.  If a variable is not
+defined in the user's own variables file, the system variables file
+(\fI@sysconfdir@/zephyr/zephyr.vars\fR) is searched for a default value.
+.TP
+.B subscribe \fIclass instance\fR [ \fIrecipient\fR ]
+Subscribe to \fIclass, instance, recipient\fR, but don't add this triplet to
+the subscriptions file.
+.TP
+.B unhide
+Make your location as maintained by the Zephyr server visible.  This does not
+affect the value of the exposure variable.
+.TP
+.B unload \fR[ \fIfile\fR ]
+Unsubscribe to all subscription triplets in current subscriptions file
+or \fIfile\fR.  Un-subscriptions in the file are ignored.
+.TP
+.B unset \fIvar\fR [ \fIvar\fR \ ... ]
+Delete the definitions of the specified Zephyr variables.
+.TP
+.B unsubscribe \fIclass instance\fR [ \fIrecipient\fR ]
+Unsubscribe to \fIclass, instance, recipient\fR, but don't remove this triplet
+from the subscriptions file.
+.TP
+.B wg_exit
+Tell the WindowGram client,
+.I zwgc(1),
+to exit.
+.TP
+.B wg_read
+Tell the WindowGram client,
+.I zwgc(1),
+to reread its description file.
+.TP
+.B wg_shutdown
+Tell the WindowGram client to shutdown; this causes it to ignore all
+notices until a wg_startup command is issued.
+.TP
+.B wg_startup
+Tell the WindowGram client to start accepting notices again; useful
+after a wg_shutdown command has been issued.
+.SH MACROS and SUBSCRIPTION FILES
+There are three macros,
+.I %host%, %canon%, \fRand\fI %me%.  %host%
+is converted to the current hostname, \fI%canon%\fR is converted to the
+official hostname as returned by 
+.I gethostbyname(3),
+and \fI%me%\fR is converted to your Kerberos principal.  These macros can be
+used in your \fI$HOME/.zephyr.subs\fR file or as arguments to commands
+to specify the
+.I class
+or 
+.I instance
+fields.  A sample \fI$HOME/.zephyr.subs\fR file might contain the following:
+.PP
+.nf
+	message,urgent,%me%
+	syslog,%host%,*
+	mail,pop,%me%
+.fi
+.PP
+.I Zctl
+reads the environment variable \fBWGFILE\fR, to find the name of the
+file where the windowgram port resides.  If \fBWGFILE\fR is not set,
+the file name defaults to /tmp/wg.\fIuid\fR, where \fIuid\fR is the
+user's UNIX uid.
+.SH UN-SUBSCRIPTIONS
+The zephyr server,
+.I zephyrd(8),
+maintains default subscriptions which are automatically added to all
+users' subscriptions at the time of their first subscription during a
+login session.  If you wish to automatically remove some of these
+default subscriptions, you use 
+.B un-subscriptions.
+When you 
+.B load
+a subscription file containing
+un-subscriptions, the un-subscriptions are automatically sent to the
+server as if you had used the
+.B unsubscribe
+command.
+.SH EXPOSURE LEVELS
+The different exposure levels affect the operation of zephyr and its
+interaction with the user, as follows:
+.TP 10
+.I none
+This completely disables Zephyr for the user. The user is not
+registered with Zephyr.  No user location information is
+retained by Zephyr.  No login or logout announcements will be
+sent.  No subscriptions will be entered for the user, and no notices
+will be displayed by 
+.I zwgc(1).
+.TP
+.I opstaff
+The user is registered with Zephyr.  No login or logout
+announcements will be sent, and location information will only be
+visible to Operations staff.  Default subscriptions and any additional
+personal subscriptions will be entered for the user.
+.TP
+.I realm-visible
+The user is registered with Zephyr.  User location information is retained by
+Zephyr and made available only to users within the user's
+Kerberos realm.  No login or logout announcements will be sent.  This
+is the system default.  Default subscriptions and any additional
+personal subscriptions will be entered for the user.
+.TP
+.I realm-announced
+The user is registered with Zephyr.  User location information is retained by
+Zephyr and made available only to users authenticated within the user's
+Kerberos realm.  Login and logout announcements will be sent, but only to
+users within the user's Kerberos realm who have explicitly requested
+such via subscriptions.  Default subscriptions and any additional
+personal subscriptions will be entered for the user.
+.TP
+.I net-visible
+The user is registered with Zephyr.  User location information is
+retained by Zephyr and made available to any authenticated user who
+requests such. Login and logout announcements will be sent only to users
+within the user's Kerberos realm who have explicitly requested such via
+subscriptions.  Default subscriptions and any additional personal
+subscriptions will be entered for the user.
+.TP
+.I net-announced
+The user is registered with Zephyr. User location information is retained by
+Zephyr and made available to any authenticated user who requests such.  Login
+and logout announcements will be sent to any user has requested such.
+Default subscriptions and any additional personal
+subscriptions will be entered for the user.
+.SH EXAMPLES
+.TP 25
+.B zctl
+Runs \fIzctl\fR in interactive mode.
+.TP
+.B zctl load
+Load subscriptions and un-subscriptions from \fI$HOME/.zephyr.subs\fR file.
+.TP
+.B zctl sub message personal
+Subscribe to personal messages, but don't add this to the
+subscriptions file.
+.TP
+.B zctl save
+Save all current subscriptions to the default subscriptions file.
+.TP
+.B zctl set exposure none
+Set your exposure level to `none', effectively turning off Zephyr.

+.TH ZLEAVE 1 "July 1, 1988" "MIT Project Athena"
+.ds ]W MIT Project Athena
+.SH NAME
+zleave \- notify you via Zephyr when you have to leave 
+.SH SYNOPSIS
+.B zleave
+[ 
+.RI [+] hhmm
+[
+.I -m "Reminder Message"
+] ]
+.br
+.B zleave 
+.I can\fR[\fIcel\fR]
+.SH DESCRIPTION
+.I Zleave
+waits until the specified time, then reminds you that you
+have to leave, using the \fIZephyr(1)\fR Notification Service.
+You are reminded 5 minutes and 1 minute before the actual
+time, at the time, and every minute thereafter.
+When you log off,
+.I zleave
+exits just before it would have sent the next message.
+.PP
+The time of day is in the form hhmm where hh is a time in
+hours (on a 12 or 24 hour clock).
+All times are converted to a 12 hour clock, and assumed to
+be in the next 12 hours.
+.PP
+If the time is preceded by `+', the alarm will go off in hours and minutes
+from the current time.
+.PP
+If no argument is given,
+.I zleave
+prompts with "When do you
+have to leave?". A reply of newline causes
+.I zleave
+to exit,
+otherwise the reply is assumed to be a time.
+This form is suitable for inclusion in a
+.I .login
+or
+.I .profile.
+.PP
+The
+.I cancel
+option cancels the currently running \fIzleave\fR.  If another
+.I zleave
+is running, it is automatically killed when a new time to leave is
+set.  The process id is stored in the file /tmp/zleave.\fIuid\fR, where
+\fIuid\fR is the user's UNIX uid.
+.PP
+If the
+.I -m
+argument is specified, the next argument
+is appended to the standard message 
+(a sentence describing how much time remains until the appointed hour)
+sent at appropriate times.
+If you want to append a multiple-word message, you normally must quote it with
+double quotes (") (This is necessary for users of
+.IR csh (1)
+and
+.IR sh (1).)
+.PP
+.I Zleave
+automatically subscribes you to Zephyr class "MESSAGE",
+instance "LEAVE".  You do not have to add anything to your
+default subscriptions file (see 
+.IR zctl (1)).
+The reminder message is displayed by the WindowGram client (usually
+.IR zwgc (1)).
+.PP
+If Zephyr is unavailable,
+.I zleave 
+acts essentially like 
+.IR leave (1).
+.PP
+Zleave ignores SIGINT, SIGQUIT, and SIGTERM.
+To get rid of it you should either log off or use the
+.I cancel
+option.

+.SH NAME
+zlocate \- find a user using Zephyr
+.SH SYNOPSIS
+.B zlocate
+[
+.B -a
+| 
+.B -d
+] [
+.B -1
+] [
+.B -p
+] user ...
+.SH DESCRIPTION
+.I Zlocate
+uses the
+.I Zephyr(1)
+Notification Service to find where a user is currently logged in.  If
+the user is not logged in, or has set his location information such that
+you do not have access to see it,
+.I zlocate
+prints "Hidden or not logged-in".  Otherwise, each machine that the
+user is currently logged into is printed, along with the time of
+login and location.  The location is usually the X window system display
+name of the user's display, but may be the terminal name if he is not
+using X or for some other reason is only using the terminal interface to
+.I zwgc(1).
+
+By default, all zlocate requests are authenticated using
+.IR Kerberos .
+If you do not have Kerberos tickets, or for some other reason do not
+want to authenticate, the
+.B -d
+option will turn off authentication.  The
+.B -a
+option is the default, authentication on.
+
+When locating multiple users,
+.I zlocate
+will display the user name on a line by itself, followed by the locations for that user. To display the user name on the same line as the output, use the
+.B -1
+option (the numeral one).
+
+To look up multiple users in parallel asynchronously, use the
+.B -p
+option.
+
+.SH DIAGNOSTICS
+.I zlocate
+exits with status zero (0) if at least one user was found, and one (1)
+if no users were found.

+.TH ZNOL 1 "July 1, 1988" "MIT Project Athena"
+.ds ]W MIT Project Athena
+.SH NAME
+znol \- notify via Zephyr upon login or logout of interesting people
+.SH SYNOPSIS
+.B znol
+[
+.BI on|off
+] [
+.BI \-f \ file
+] [
+.BI \-u \ username
+] [
+.BI \-l
+] [
+.BI \-q
+]
+.SH DESCRIPTION
+.I Znol
+provides a way for you to be notified when "interesting" people log in
+or out.  It uses the
+.I Zephyr(1)
+Notification Service, which causes a message to appear on your screen
+for every person specified in a namelist (which defaults to
+$HOME/.anyone).  The namelist should have one login name per line.  Any
+line starting with `#' is considered a comment and ignored.
+Anyone in the namelist who is logged in when
+.I znol
+is executed is printed to stdout.  The control arguments are as
+follows:
+.TP 12
+.B on|off
+Turns notification on or off.
+.TP
+.B \-f
+The namelist file is taken to be
+.I file.
+If
+.I file
+is "-", then the standard input is used instead of a file. If
+.I file
+does not exist, an error message is printed, and
+.I znol
+exits.
+This option may not be used in conjunction with the
+.B \-u
+option.
+.TP
+.B \-l
+Causes
+.I znol
+to just list the people in the namelist who are currently logged in,
+without subscribing to the login messages.   This option may not be used
+in conjunction with the
+.BI \-q
+option.
+.TP
+.B \-q
+Disables printing who is currently logged in when subscribing.  This
+option may not be used in conjunction with the
+.BI \-l
+option.
+.TP
+.B \-u
+Instead of reading a file to specify the "interesting" users, the next
+argument is used as the only "interesting" user.  This option may not be
+used in conjunction with the
+.B \-f
+option.
+.SH EXAMPLES
+.nf
+.in +.5in
+znol
+.in -.5in
+.fi
+reads the standard namelist file, prints the locations of any users
+named therein which can be found on the system, and enters subscriptions
+for notices about those users.
+.nf
+.in +.5in
+znol \-l \-u foo
+.in -.5in
+.fi
+prints the location (if visible) of the user 'foo'.

+.ds ]W MIT Project Athena
+.SH NAME
+zshutdown_notify \- notify users of impending shutdown via Zephyr
+.SH SYNOPSIS
+.B zshutdown_notify
+.SH DESCRIPTION
+.I zshutdown_notify
+reads the standard input until EOF is reached, and then sends a Zephyr
+notice with the official hostname, the collected input, and a warning
+message as the message body of the notice.
+The notice is sent to class FILSRV, instance 
+.I <hostname>,
+recipient "*", where <hostname> is the official hostname of the sending host.
+.PP
+Any users who are using resources on the sending host are expected to
+subscribe to these messages so they will be warned of any impending
+shutdowns.
+.PP
+.I zshutdown_notify
+is usually invoked from within
+.I /etc/shutdown.

+zstat \- display Zephyr statistics
+.SH SYNOPSIS
+.B zstat
+[
+.BI -h
+] [
+.BI -s
+] [
+.BI host \ ...
+]
+.SH DESCRIPTION
+.I Zstat
+is used to display statistics reported by a HostManager,
+.I zhm(8),
+or a Zephyr Server
+.I zephyrd(8),
+or both.
+.TP 12
+.B \-h
+is used to indicate that only HostManager statistics should be displayed.
+.TP
+.B \-s
+is used to indicate that only server statistics should be displayed.
+.TP
+If no hosts are specified, the current host is assumed.
+When both HostManager and server statistics are displayed,
+statistics from the current server for each host are displayed.

+.SH DESCRIPTION
+.I Zwrite
+sends a message from you to another user through the
+.I zephyr(1)
+notification service.  The user must have subscribed to messages of
+the appropriate class and instance using the
+.I zctl(1)
+program.
+.PP
+.I Zwrite
+understands the following options.
+.TP 12
+.B \-a
+Causes
+.I zwrite
+to send the message authenticated, using
+.I Kerberos
+to perform the authentication.  This is the default.
+.TP
+.B \-d
+Causes
+.I zwrite
+to send the message unauthenticated.
+.TP
+.B \-v
+Causes
+.I zwrite
+to print what type of message it is sending, and whether or not it was
+successful.
+.TP
+.B \-q
+Forces
+.I zwrite
+to suppress information about whether or not the message was sent.
+.TP
+.B \-t
+Prevents
+.I zwrite
+from expanding tabs in the message into appropriate spaces.  Normally
+.I zwrite
+will expand any tabs it finds into the appropriate number of spaces to
+maintain separation based on 8-character tab stops.
+.TP
+.B \-l
+Causes
+.I zwrite
+to ignore `.' on a line by itself in the input and only end a typed
+message when the user types the end-of-file character (usually
+control-D).  When the input is not a terminal, this is the default action.
+.TP
+.B \-u
+Sends an urgent message.  This changes the
+.I zephyr
+instance of the message to ``URGENT''.
+.TP
+.B \-o
+Causes
+.I zwrite
+to ignore the Zephyr variables 
+.IR zwrite-class ,
+.IR zwrite-inst ,
+and
+.I zwrite-opcode
+when picking a default class, instance, and opcode.
+.TP
+.B \-n
+prevents
+.I zwrite
+from sending a PING message to verify the recipient is subscribing to
+messages.  By default,
+.I zwrite
+will send a notice to the destination class, instance, and recipient,
+with opcode ``PING'' before sending the message.  If the PING is sent,
+and the server response indicates there are no recipients subscribed to
+your message,
+.I zwrite
+exits without sending a message.
+When the
+.B \-n
+option is used, no PING is sent.
+.TP
+.B \-C
+prepends a "CC:" line to the body of the message indicating the
+recipients of the message. This is strictly a convenience: the
+presence of a "CC:" line at the top of a zephyr body does not
+necessarily indicate that this option was used, or that the message
+really was sent to the listed users, and its lack doesn't indicate
+that the message was not sent to multiple users.
+.TP
+.B \-U
+Send an unacked message.
+.I zwrite
+will not wait for acknowledgement that the message was sent, nor will
+it issue a PING before sending.
+.TP
+.B \-s \fIsignature\fR
+sets the signature to be included in the message.  This overrides both
+the user's name (as found in the password file) and any
+setting of the Zephyr variable 
+.IR zwrite-signature .
+.I signature
+must
+be a single argument, hence when using a shell it should be quoted with
+double quotes.  A
+.I signature
+argument of "" leaves the signature in
+the message empty.
+.TP
+.B \-c \fIclass\fR
+Allows a user to specify a different class for the message.  This allows
+a message to be sent to a large group of people with some degree of
+security.  See
+.I zephyr(1)
+and
+.I zephyrd(8)
+for a description of how to restrict access to classes.  When this option
+is specified, the message is sent to recipient "*" unless an additional
+list of recipients is specified.
+.br
+This argument may not be used in conjunction with the \-f option.
+.TP
+.B \-i \fIinstance\fR
+Allows a user to specify a different instance than the default.
+When this option is used, the message is sent to recipient "*" unless an
+additional list of recipients is specified.  This allows a message to be
+sent to a large group of people (e.g. a development group) just by having
+the members subscribe to messages of class "MESSAGE", the specified instance,
+and recipient "*".
+.br
+This argument may not be used in conjunction with the \-f option.
+.TP
+.B \-r \fIrealm\fR
+Allows a user to specify a different realm for the message, if the
+server supports interrealm Zephyr.
+.TP
+.B \-S \fIsender\fR
+Specify a sender.  The message will be sent unauthenticated.
+.TP
+.B \-F \fIformat\fR
+Allows a user to specify a different default format for the message.
+.TP
+.B \-O \fIopcode\fR
+Allows a user to specify a different opcode for the message.
+Some Zephyr notice display programs may use the opcode to decide how
+to display a notice.
+.TP
+.B \-f \fIarg\fR
+Allows a user to specify an argument to be interpreted as a filesystem
+specification.  The class is set to 
+.BR FILSRV .
+he instance is set
+to
+.I arg
+as modified:
+If
+.I arg
+contains no colons (`:'), it is assumed to
+be a host name, and it is converted into an official host name via 
+.I gethostbyname(3).
+If
+.I arg
+contains a colon, the portion preceding the colon is
+treated as a host name, and the colon and any trailing characters are
+appended to the offical host name returned by
+.I gethostbyname.
+If the name fails to resolve into an official host name, the instance is
+set to
+.I arg
+unmodified.
+.br
+This option may not be used in conjunction with the \-c or \-i option.
+.TP
+.B \-m
+.I Zwrite
+sends the remaining arguments on the command line as the message.
+.PP
+If the
+.I \-m
+option is not specified, the user is prompted for the message to be
+sent.  The message may be terminated by typing ^D or ``.'' on a line
+by itself.
+.PP
+The default class for messages is ``MESSAGE'', the default instance
+is ``PERSONAL'', andthe default opcode is ``'' (an empty string).
+These defaults can be overridden by setting the Zephyr
+variables
+.IR zwrite-class ,
+.IR zwrite-inst ,
+and
+.IR zwrite-opcode ,
+respectively.
+Command-line options can override the defaults.
+.PP
+If the class is ``MESSAGE'' and the instance is either ``PERSONAL'' or
+``URGENT'', a recipient must be specified.  These comparisons are
+case-sensitive.
+.PP
+Unless the
+.B \-s
+option is used, the contents of the Zephyr variable
+.I zwrite-signature
+are used to augment the user's username in the
+message.  If
+.I zwrite-signature
+is not set and the
+.B \-s
+option is not specified, the user's full name (as specified in the
+password file) is used instead.
+.SH BUGS
+Tab expansion should really be done by the receiver of the message.
+.br
+The \-u option is provided for compatibility with old versions of
+.I zwrite
+and is not necessarily useful for sending messages to users who do not
+have old subscription files.

+Description: Potentially incompatible upgrade
+ You appear to be upgrading from a version of zephyr that uses
+ Kerberos version 4 to authenticate.  Kerberos version 4 support has
+ been removed from Debian, and accordingly from zephyr.  This version
+ of zephyr uses Kerberos 5 to authenticate, and thus your servers must
+ have been upgraded for it to be useful.
+ .
+ A server that authenticates both ways can be built for lenny from the
+ zephyr source package, see:
+   /usr/share/doc/libzephyr4-krb5/README.krb4-5
+ .
+ Continue with the upgrade?
