+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 4 service, you can enable Kerberos support
+by adding the option "--with-krb4=KRBPREFIX" to the configure line,
+where KRBPREFIX/include and KRBPREFIX/lib are the direcetories you
+have the Kerberos libraries installed in.
+
+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 send mail to zephyr-bugs@mit.edu.

+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.
+
+The Zephyr system version number is kept in server/version.c, and
+should be updated when releases are made.
+
--- /dev/null
+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.
+
+3. If you configured Zephyr with Kerberos 4 support, make a service
+key "zephyr.zephyr@<your realm>" and install a srvtab for that service
+as "srvtab" in the configuration directory of each of your zephyr
+servers.
+
+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 a snapshot 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.
+
+Bug reports or patches should go to bug-zephyr@mit.edu. Please do not
+send questions about snapshots; they are not supported.
+
+To find out how to configure, build, and install Zephyr, read the file
+INSTALL.

+To find out how to operate a Zephyr service, read the file OPERATING.
+
+To find out how to use an existing Zephyr service, read the file
+USING.
+

+This file explains how to use an existing Zephyr service once you've
+built and installed the Zephyr 2.0 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,username>.
+
+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.

+.TH XZWRITE 1 "7 February 1989"
+.SH NAME
+xzwrite \- X application to write to another user via Zephyr
+.SH SYNOPSIS
+.B xzwrite
+[ -toolkitoption ... ] [-s signature] [+d | -d] [+n | -n] [+v | -v]
+[+yd | -yd] [+av | -av] [+ci | -ci] [-my yanks] [+l | -l] [+a | -a]
+[+x | -x] [+z | -z] [+pong | -pong] [+reply | -reply]
+
+.SH DESCRIPTION
+.I Xzwrite
+is an X application that sends messages to other users
+through the
+.IR Zephyr (1)
+notification service. It puts an icon on the
+screen that allows the user to send a message, select the destination
+of a message, or exit. The program remains active until explicity
+told to exit, thus eliminating the need to run a program every time
+the user wants to send a zephyr message.
+.SH USING THE DESTINATION LIST
+.PP
+.I Xzwrite
+maintains a list of 'destinations'; that is, a list of
+<class, instance, recipient> triples that a user can send messages to.
+When a user selects a destination, all subsequent messages will be
+sent to that triple, until a new destination is selected.
+.I Xzwrite
+can get its list of destinations from the files .xzwrite.dest,
+.anyone, or .zephyr.vars in the
+user's home directory. These files must consist of a list of lines, and
+each is interpreted in the following way: a line containing no commas
+is taken to mean <MESSAGE,PERSONAL,string>; a line with one comma is
+taken to be either <class,instance,*> or <MESSAGE,instance,recipient>
+depending on the value of the classInst resource (see below); a line
+with two commas is taken to be <class,instance,recipient>. A line
+that begins with an exclamation point (!) is treated as an
+"unsubscription" and has the effect of removing destinations read
+from any other file that match the destination on that line. The lines
+must appear
+.B WITHOUT WHITESPACE
+between the fields and with a linefeed between each line. Blank lines
+and lines beginning with an octothorpe (#) are ignored.
+.PP
+
+Clicking the left button in the
+.I xzwrite
+icon pops up the editor and
+destination list. Clicking with the left button in the destination
+list selects the highlighted destination; clicking with the right
+button deletes the highlighed destination. Clicking the middle button
+invokes the action CreateDest (see ACTIONS below) that prompts the
+user for a new <class,instance,recipient> triple to be added to the list.
+
+.PP
+
+If the user specifies a destination in the .xzwrite.dest file
+with an instance or recipient of "...",
+.I xzwrite
+will prompt the user to enter an instance or recipient when the
+message editor is popped up. Setting both instance and recipient to
+"..." (ie: <MESSAGE,...,...>) works. The new
+<class,instance,recipient> triple formed each time a destination with
+"..." is used may or may not be added to the destination list, depending
+on the addVars resource (see below.)
+
+.PP
+
+While the mouse pointer is inside the
+.I xzwrite
+icon, the mouse buttons have the following effect:
+.TP
+.B Left button:
+Pops up the editor and destination list so the user can create and
+send messages.
+.TP
+.B Right button:
+Pops up a list of things that can be changed while xzwrite is running.
+Clicking the "Change Signature" box causes
+.I xzwrite
+to prompt for a new signature, to be used in future messages. All the
+others toggle options which are initially set by resources or
+command-line arguments. The "Quit XZWRITE" causes
+.I xzwrite
+to exit.
+.TP
+.B Ctrl-Right button:
+Exits
+.IR xzwrite .
+
+.SH USING THE MESSAGE EDITOR
+There are four buttons in the message editor. The Send button
+sends the text currently in the message editor to the current
+destination, optionally clearing the message editor at the same time.
+The Clear Editor button clears the message editor. The Yank-Prev button yanks
+the previous message, along with its destination, into the message
+editor. The Yank-Next button yanks the next message (or the first
+message in the yank buffer, if Yank-Prev has not been called) into the
+message editor. The yank buffer is circular, so old messages are
+periodically overwritten by new ones, and stores the previous (by
+default) 25 messages.
+.PP
+The following key sequences have been defined for convenience:
+.PP
+.nf
+ Ctrl-Return Send message
+ Meta-O Store current message, yank previous
+ Meta-P Yank Previous
+ Meta-N Yank Next
+
+.SH OPTIONS
+
+.I Xzwrite
+will accept all X Toolkit command-line options and
+resource database specifications, under the name 'XZwrite'; for more
+information, see
+.IR X (1).
+The instance names of the different parts of
+.I xzwrite
+are as follows (each should be preceded by XZwrite* in the
+user's .Xresources file. For examples of how to use these resource
+names, look in /usr/athena/lib/zephyr/XZwrite.)
+
+.nf
+ toplevel - the top level shell
+ icon - the top level "Z" icon
+
+ sendWindow - the popup shell for the editor/destlist
+ sendForm - the form holding the edit tree and dest tree
+ sendClose - button to close sendWindow
+
+ editPane - the pane holding editor widgets
+ editTitle - the label holding the zephyr triple
+ editForm - the box holding editor command buttons
+ editSend - button to send message
+ editClear - button to clear editor
+ editPrev - button to yank previous
+ editNext - button to yank next
+ editor - the text editor
+
+ destForm - the form holding the destinations list/button
+ destScroll - the scrollbar holding the list
+ destList - the destination list
+
+ menuWindow - the popup shell for the menu
+ menuForm - the form holding the menu list/button
+ menuClose - the Close Window button for the dest list
+ signature - button to change signature
+ closeOnSend
+ pings
+ verbose
+ authentic
+ yankDest
+ addGlobals
+ classInst
+ exitProgram
+
+ getStringWindow - the popup shell for dialog boxes (GetString.c)
+ getStringForm - the form containing the dialog widgets
+ getStringTitle - the title label width
+ getStringEdit - the text editor
+ getStringAccept - the accept button
+ getStringCancel - the cancel button
+
+.fi
+
+.PP
+In addition,
+.I xzwrite
+will accept the following command-line options
+(or resource database specifications). Each should be preceded by
+XZwrite* in the user's .Xresources file. When a command-lie

+.br
+.ns
+.HP 5
+.B -v (verbose = false)
+.br
+When true, causes
+.I xzwrite
+to inform the user no one received a sent message by beeping. This
+is useful if the user wants to know if someone logged out between
+the time when the editor is popped up (when a PING is sent) and when
+the message is actually sent.
+.TP

+.B +a (readAnyone = true)
+.br

+.B -l (trackLogins = false)
+.br
+When true,

+.I xzwrite
+performs a "zlocate". Note that this resource is only used when
+trackLogins is true.
+.TP
+.B -s (signature)
+Specifies the 'signature' for all messages sent. The signature will
+appear as the first field in every message sent.
+.I Xzwrite
+will also look in the user's .zephyr.vars file to a signature, first
+for the variable xzwrite-signature and then for the variable
+zwrite-signature. If neither is found,

+separated by a comma is interpreted as a class and instance, with
+a recipient of "*". When it is false, the same string is interpreted
+as an instance and recipient, with a class of MESSAGE.
+.TP
+.B +yd (yankDest = true)
+.br
+.ns
+.HP 5
+.B -yd (yankDest = false)
+.br
+When yd is set to true, yanking a previous message in the message editor
+also restores the original destination of the message. When set to false,
+only the message text is yanked, and the current destination remains
+unchanged.
+.TP
+.B +av (addVars = true)
+.br
+.ns
+.HP 5
+.B -av (addVars = false)
+.br
+When av is set to true, destinations that are specified as the result
+of a recipient or instance of "..." are added to the destinations list
+so they can be selected again.
+.TP
+.B +reply (autoReply = true)
+.br
+.ns
+.HP 5
+.B -reply (autoReply = false)
+.br
+When autoReply is set to true, xzwrite subscribes to <MESSAGE,*,%me%>
+(in other words, all messages sent directly to the user). Each time
+such a message is received, a destination that will reply to the
+sender on the same instance is added to the destination list, if it is
+not already there.
+
+.SH ACTIONS
+
+Every useful action that
+.I xzwrite
+can perform can be bound to any sequence of X events through the
+mechanism of translation tables. The following action procedures
+available to the user.
+.PP
+.nf
+ OpenSend
+ CloseSend
+ Pops up/Pops down the message editor/destination list.
+
+ SendMessage
+ Sends the message in the editor to the current destination.
+
+ ClearEditor
+ Clears the editor.
+
+ YankStore
+ Stores the contents in the message editor in the Yank buffer.
+
+ YankPrev
+ YankNext
+ Puts the previous/next item in the yank buffer into the editor,
+ optionally restoring the destination as well.
+
+ SelectDest
+ DeleteDest
+ Selects/deletes the hightlighed destination.
+
+ CreateDest
+ Prompts the user for a <class,instance,recipient> triple to
+ be added to the destinations list.
+
+ OpenMenu
+ CloseMenu
+ Pops up/Pops down the options menu.
+
+ ToggleOption
+ Toggles the option corresponding to the hightlighed item on the
+ options menu.
+
+ Signature
+ Pops up a dialog box and changes the Zephyr signature to whatever
+ is typed into it.
+
+For examples on how to use these action procedures, look in
+/usr/athena/lib/zephyr/XZwrite.

+.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 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
+Tell the Zephyr servers to flush all location information associated with
+the user. This should only be used to remove any incorrect data that may have
+been left after a system crash.
+.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/etc/athena/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.

+.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
+] 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.
+
+.SH DIAGNOSTICS
+.I zlocate
+exits with status zero (0) if at least one user was found, and one (1)
+if no users were found.

+.ds ]W MIT Project Athena
+.SH NAME
+zmailnotify \- retrieve mail headers from post office and transmit via Zephyr
+.SH SYNOPSIS
+.B zmailnotify
+.SH DESCRIPTION
+.I zmailnotify
+connects to the invoking user's POP post office and retrieves the From,
+To, and Subject fields of waiting messages, and then sends one Zephyr
+notice per message to class MAIL, instance POPRET, recipient
+.I <user@realm>,
+where <user@realm> is the invoking user's username concatenated with the
+local Zephyr realm (e.g. jruser@ATHENA.MIT.EDU).
+.PP
+.I zmailnotify
+is intended to be executed by
+.I zwgc(1)
+when notifications of spooled mail (such
+as those generated by \fIzpopnotify(8)\fR) are delivered.
+By default, these notifications are not delivered, nor are they acted
+upon. To receive the notices, you must subscribe to class MAIL,
+instance POP, recipient username@realm (see \fIzctl\fR(1)).
+Once you subscribe to these notices, by default they will be simply
+displayed on your display or terminal by
+.I zwgc(1).
+To have
+.I zmailnotify
+executed when they are delivered, you must copy the system default
+windowgram description file (\fI/usr/athena/lib/zephyr/zwgc.desc\fR) to your home
+directory as filename
+.I ~/.zwgc.desc
+and follow the directions contained in that file pertaining to
+.B MAIL NOTIFICATION.
+.PP
+.I zmailnotify
+only retrieves four headers at one time in order to reduce the
+competition for the mailbox lock on the post office. If more than four mail
+messages are waiting,
+.I zmailnotify
+will only retrieve the four most recent mail headers.
+.PP
+To check for mail already waiting when you log in, use the standard MH
+program
+.I msgchk(1).
+.SH BUGS
+.I zmailnotify
+only sends notification of mail which appears to be unique.
+Uniqueness is determined by comparing the To:, From:, and Subject:
+fields of the message with the last checked mail message; if the
+three fields match exactly, the new message is
+not considered unique. The To:, From:, and Subject: fields of the last
+message are stored in the file
+.IR $HOME/.maillock .
+.SH FILES
+$HOME/.maillock

+.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'.

+.TH ZSHUTDOWN_NOTIFY 8 "July 8, 1988" "MIT Project Athena"
+.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.

+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 \-m
+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 \-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 \-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.

+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE. See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+ -h, --help display this help and exit
+ --help=short display options specific to this package
+ --help=recursive display the short help of all the included packages
+ -V, --version display version information and exit
+ -q, --quiet, --silent do not print \`checking...' messages
+ --cache-file=FILE cache test results in FILE [disabled]
+ -C, --config-cache alias for \`--cache-file=config.cache'
+ -n, --no-create do not create output files
+ --srcdir=DIR find the sources in DIR [configure dir or \`..']

+.SH NAME
+zephyr \- Zephyr Notification Service
+.SH DESCRIPTION
+.PP
+Zephyr is a notice transport and delivery system developed at MIT
+which runs under 4.3BSD Unix.
+.PP
+A Notice Transport and Delivery system is a method of getting small
+quantities of time sensitive information efficiently from one client
+(or server) on a network to another. The object is to accomplish this
+with the highest possible fan-out (i.e., client to server ratio) while
+maintaining both network and server performance. Zephyr is a
+multi-cast notice transport and delivery system based upon an
+authenticated datagram protocol. Localized Zephyr servers provide
+routing, queueing and dispatching services to clients which
+communicate with them via the Zephyr Client Library. Two special
+purpose Zephyr clients, the WindowGram client and the HostManager
+client provide user and client host communication support.
+.PP
+.I Zephyrd(8)
+servers run on designated server machines. These servers maintain a
+database of subscriptions and locations for every user using Zephyr.
+The servers stay in contact with one another, and provide a reliable
+backup system (via duplication) in the event of network failures.
+.PP
+Each client machine on the network runs a
+.I zhm(8)
+HostManager client program which is the link between the Zephyr
+servers and the users. User programs send notices to the HostManager,
+and the HostManager forwards these notices to the nearest server for
+action. The HostManager is responsible for ensuring that the notices
+reach a server, and for finding a new one if its server fails to respond.
+.PP
+Each user on the network usually runs a WindowGram client program
+automatically upon login.
+.I Zwgc(1)
+displays notices to the user, and handles user
+responses. Only notices to which the user has subscribed will be sent
+to the WindowGram client.
+.PP
+Subscriptions are handled through the
+.I zctl(1)
+program. This program allows the user to add or delete subscriptions
+from Zephyr, to add the subscriptions to a file, and to perform other
+miscellaneous functions.

+libdyn.a -- Release 1.0
+
+A C Dynamic Object is an array that takes care of resizing itself as
+elements are added and deleted from it. It can be of any type for
+which sizeof is defined and for which an address of a variable of that
+type can be passed to a function.
+
+To build libdyn.a, simply type "make depend all" (if you don't have
+the program makedepend, of course, leave out the "depend" part). If
+your system's bcopy() cannot handle overlapping regions, you'll need
+to write one that can. (Left as an excercise for the reader..)
+
+The library should compile and work without modification on a vast
+number of systems. It only uses 5 external functions: malloc,
+realloc, free, bcopy, and fprintf (to stderr). Of these, only bcopy
+should need to be changed for other systems (such as MS-DOS) and it
+could probably be done with a -D flag to the compiler.
+
+The test/demo program is built by "make all". This program produces
+the library's debugging output (to stderr) as well as some of its own
+output (to stdout).
+
+The library has been tested (with test.c) on a VAX VSII, VAXstation
+3100, DECstation 3100, and IBM RT all running BSD4.3 (except for the
+DECstation, which was running Ultrix V2.1).
+
+An earlier version of this library was posted to alt.sources. This
+version contains one new function (DynInsert) and slightly cleaner
+code, but no bugfixes (no bugs were found).

+.SH NAME
+dyn \- the C Dynamic Object library
+
+.SH DESCRIPTION
+
+A C Dynamic Object is an array that takes care of resizing
+itself as you add and delete elements from it. It can be of any type
+for which sizeof is defined and for which an address of a variable of
+that type can be passed to a function. The library containing the
+functions described below is called
+.IR libdyn.a ,
+and the necessary declarations to use them are in
+.RI < dyn.h >.
+.PP
+A DynObject is actually a structure that contains an array and a
+couple of integers to maintain necessary state information. When a
+Dyn function is said to operate on "the object" or "the array", it is
+operating on the array stored in the structure while at the same time
+updating internal state information.
+
+.SH LIST OF FUNCTIONS
+.nf
+DynObject DynCreate(size, increment)
+ int size, increment;
+.fi
+.PP
+.IR Requires :
+.I size
+and
+.I increment
+are greater than zero.
+.PP
+.IR Effects :
+Creates a new DynObject that will store elements of size
+.I size
+and will allocate memory in blocks large enough to hold exactly
+.I increment
+elements. For example, if you are storing 8-byte double
+precision numbers and
+.I increment
+is 5, each 5th element you add to the object will cause it to request
+40 more bytes (8 * 5) from the operating system. If
+.I increment
+is zero, a default value is used (currently 100). This is the only
+time the programmer deals with a dynamic object's memory allocation.
+.PP
+.IR Returns :
+.B DynCreate
+returns the new DynObject, or NULL if there is insufficient memory.
+.PP
+.nf
+int DynDestroy(obj)
+ DynObject obj;
+.fi
+.PP
+.IR Modifies :
+obj
+.PP
+.IR Effects :
+Frees all memory associated with
+.IR obj .
+The results of calling any Dyn function on a destroyed object are
+undefined (except for DynCreate, which resets the object).
+.PP
+.IR Returns :
+.B DynDestroy
+returns DYN_OK.
+.PP
+.nf
+int DynAdd(obj, el)
+ DynObject obj;
+ DynPtr el;
+.fi
+.PP
+.IR Modifies :
+obj
+.PP
+.IR Effects :
+Adds the element pointed to by
+.I el
+to the object
+.IR obj ,
+resizing the object if necessary.
+The new element becomes the last element in obj's array.
+.PP
+.IR Returns :
+.B DynAdd
+returns DYN_OK on success or DYN_NOMEM if there is insufficient
+memory.
+.PP
+.nf
+int DynInsert(obj, index, els, num)
+ DynObject obj;
+ DynPtr els;
+ int index, num;
+.fi
+.PP
+.IR Modifies :
+obj
+.PP
+.IR Effects :
+Inserts the array of
+.I num
+elements, pointed to by
+.IR els,
+into the object
+.I obj
+starting at the array location
+.IR index ,
+resizing the object if necessary. Order is preserved; if you have the
+array "1 2 3 4 5" and insert "10 11 12" at the third position, you
+will have the array "1 2 10 11 12 3 4 5".
+.PP
+.IR Returns :
+.B DynInsert
+returns DYN_BADINDEX if
+.I index
+is not between 0 and
+.BR DynSize ( obj ) ;

+/* We have three operations which we need to be able to perform
+ * quickly: adding a timer, deleting a timer given a pointer to
+ * it, and determining which timer will be the next to go off. A
+ * heap is an ideal data structure for these purposes, so we use
+ * one. The heap is an array of pointers to timers, and each timer
+ * knows the position of its pointer in the heap.
+ *
+ * Okay, what is the heap, exactly? It's a data structure,
+ * represented as an array, with the invariant condition that
+ * the timeout of heap[i] is less than or equal to the timeout of
+ * heap[i * 2 + 1] and heap[i * 2 + 2] (assuming i * 2 + 1 and
+ * i * 2 + 2 are valid * indices). An obvious consequence of this
+ * is that heap[0] has the lowest timer value, so finding the first
+ * timer to go off is easy. We say that an index i has "children"
+ * i * 2 + 1 and i * 2 + 1, and the "parent" (i - 1) / 2.
+ *
+ * To add a timer to the heap, we start by adding it to the end, and
+ * then keep swapping it with its parent until it has a parent with
+ * a timer value less than its value. With a little bit of thought,
+ * you can see that this preserves the heap property on all indices
+ * of the array.
+ *
+ * To delete a timer at position i from the heap, we discard it and
+ * fill in its position with the last timer in the heap. In order
+ * to restore the heap, we have to consider two cases: the timer
+ * value at i is less than that of its parent, or the timer value at
+ * i is greater than that of one of its children. In the first case,
+ * we propagate the timer at i up the tree, swapping it with its
+ * parent, until the heap is restored; in the second case, we
+ * propagate the timer down the tree, swapping it with its least
+ * child, until the heap is restored. */
+
+/* In order to ensure that the back pointers from timers are consistent
+ * with the heap pointers, all heap assignments should be done with the
+ * HEAP_ASSIGN() macro, which sets the back pointer and updates the

+.ds ]W MIT Project Athena
+.SH NAME
+zephyrd \- Zephyr server daemon
+.SH SYNOPSIS
+.I /usr/etc/zephyrd
+[
+.BI \-d
+]
+.SH DESCRIPTION
+.I zephyrd
+is the central server for the Zephyr Notification System.
+It maintains a location database of all currently logged-in users, and a
+subscription database for each user's Zephyr clients.
+.PP
+.I zephyrd
+communicates with daemons running on other Zephyr server hosts, to
+provide a reliable service.
+.PP
+While running, any unusual conditions are recorded via
+.I syslog(3)
+to facility local6 at various levels.
+The
+.BI \-d
+option enables logging of additional debugging information.
+.PP
+When a
+.B zephyrd
+is executed, it requests a list of server machines from Hesiod and
+initializes its state from any
+\fIzephyrd\fRs executing on the other known servers. This initialization
+is only performed after the \fIzephyrd\fRs have authenticated themselves
+to each other via Kerberos.
+The server then enters a dispatch loop, servicing requests from clients and
+other servers.
+.SH SIGNALS
+.B SIGUSR1
+enables logging of additional debugging information.
+.br
+.B SIGUSR2
+disables the logging of additional debugging information.
+.br
+.B SIGHUP
+causes
+.I zephyrd
+to re-read the default subscription file and to re-query Hesiod about
+valid peers. Any peers which are not responding and no longer
+mentioned in Hesiod are flushed; any peers not previously named by
+Hesiod are added.
+.br
+.B SIGINT \fRand\fB SIGTERM
+cause
+.I zephyrd
+to gracefully shut down.
+.br
+.B SIGFPE
+causes
+.I zephyrd
+to dump the location and subscription databases to
+.I /var/tmp/zephyr.db
+in an ASCII format.
+.SH ACCESS CONTROL
+Certain notice classes are restricted by the Zephyr server. Each such
+class has access control lists enumerating who may transmit (xmt-*.acl) or
+subscribe to that particular class. Subscriptions may be
+restricted either absolutely (sub-*.acl files), or by instance restrictions.
+iws-*.acl files control subscriptions to wildcarded instances.
+iui-*.acl files control subscriptions to instances which are not the
+Kerberos principal identity of the subscriber.
+If an access control list of a given type is absent, there is no
+restriction of that type on the class, except that any notices of the
+class must be authenticated.
+The class registry lists all classes which are restricted.
+.SH FILES
+.TP 10
+.I /usr/athena/lib/zephyr/class-registry.acl:
+List of classes which are restricted
+.TP

+.I /usr/athena/lib/zephyr/ztkts:
+Current Kerberos tickets for exchange with other servers
+.TP
+.I /usr/tmp/zephyr.db:
+File containing an ASCII dump of the database.
+.SH BUGS
+The current implementation of the Zephyr server (\fIzephyrd(8)\fR) makes
+no distinction between realm-announced, net-visible and net-announced
+exposure levels.

+/* We have three operations which we need to be able to perform
+ * quickly: adding a timer, deleting a timer given a pointer to
+ * it, and determining which timer will be the next to go off. A
+ * heap is an ideal data structure for these purposes, so we use
+ * one. The heap is an array of pointers to timers, and each timer
+ * knows the position of its pointer in the heap.
+ *
+ * Okay, what is the heap, exactly? It's a data structure,
+ * represented as an array, with the invariant condition that
+ * the timeout of heap[i] is less than or equal to the timeout of
+ * heap[i * 2 + 1] and heap[i * 2 + 2] (assuming i * 2 + 1 and
+ * i * 2 + 2 are valid * indices). An obvious consequence of this
+ * is that heap[0] has the lowest timer value, so finding the first
+ * timer to go off is easy. We say that an index i has "children"
+ * i * 2 + 1 and i * 2 + 1, and the "parent" (i - 1) / 2.
+ *
+ * To add a timer to the heap, we start by adding it to the end, and
+ * then keep swapping it with its parent until it has a parent with
+ * a timer value less than its value. With a little bit of thought,
+ * you can see that this preserves the heap property on all indices
+ * of the array.
+ *
+ * To delete a timer at position i from the heap, we discard it and
+ * fill in its position with the last timer in the heap. In order
+ * to restore the heap, we have to consider two cases: the timer
+ * value at i is less than that of its parent, or the timer value at
+ * i is greater than that of one of its children. In the first case,
+ * we propagate the timer at i up the tree, swapping it with its
+ * parent, until the heap is restored; in the second case, we
+ * propagate the timer down the tree, swapping it with its least
+ * child, until the heap is restored. */

+.SH NAME
+zhm \- Zephyr HostManager
+.SH SYNOPSIS
+.B /etc/athena/zhm
+[
+.BI -d
+] [
+.BI -h
+] [
+.BI -r
+] [
+.BI -i
+] [
+.BI -f
+] [
+.BI server
+.BI ...
+]
+.SH DESCRIPTION
+.I Zhm
+is the link between a client machine and the zephyr server. All
+notices sent from programs on the client are funneled through
+.I zhm.
+This allows all client programs to be much simpler in function, since
+the HostManager is responsible for handling errors, retransmitting
+lost notices, and holding all notices until they are acknowledged.
+.PP
+The
+.I -d
+option turns on debugging mode, and sends its information to syslog
+LOG_DAEMON messages.
+.PP
+The
+.I -h
+option causes
+.I zhm
+to send a shutdown message and exit upon delivery of a SIGHUP signal.
+The normal action on SIGHUP is to send a flush notice to the zephyr server.
+.PP
+The
+.I -r
+option causes
+.I zhm
+to send a boot notice to the server and exit when the notice is acknowledged.
+.PP
+The
+.I -i
+option indicates that
+.I zhm
+is being started by
+.I inetd(8).
+When this option is specified,
+.I zhm
+assumes that file descriptor zero (0) is bound to the UDP datagram port
+designated for hostmanager use. In this mode, SIGHUP is handled as if the
+.I -h
+option were specified.
+.PP
+The
+.I -f
+option disables the "flush" operation which allows any client to flush
+all subscriptions for the host.
+.PP
+The optional
+.I server
+arguments are used to replace the set of server names supplied by
+the
+.I hesiod(3)
+name server.

+ * dictionary - a module implementing a generic dictionary. That is,

+ *
+ * Overview:
+ *
+ * A dictionary is a set of bindings which bind values of some
+ * type (this type is the generic parameter of the dictionary) to
+ * strings. At most one value can be bound to any one string.
+ * The value that a string is bound to can be changed later.
+ * Bindings can also be deleted later. It is also possible to
+ * enumerate all of the bindings in a dictionary. Dictionarys
+ * are heap based and must be created & destroyed accordingly.
+ *
+ * Note: This module assumes that malloc NEVER returns 0 for reasonable
+ * requests. It is the users responsibility to either ensure that
+ * this happens or supply a version of malloc with error
+ * handling.
+ *
+ * Dictionarys are mutable.
+ *
+ * Implementation:
+ *
+ * A standard chaining hash table is used to implement dictionarys.
+ * Each dictionary has an associated size (# of slots), allowing
+ * different size dictionaries as needed.

+.SH NAME
+zwgc \- Zephyr Windowgram Client program
+.SH SYNOPSIS
+.B zwgc
+[ \-reenter ] [ \-nofork ] [ \-ttymode ] [ \-f
+.I filename
+] [ \-subfile
+.I filename
+] [ \-loc
+.I text
+] [ \-default
+.I portname
+] [ \-disable
+.I portname
+] ... [ output driver options ]
+[ X Toolkit options... ]
+.SH DESCRIPTION
+.I Zwgc
+is the main
+.I zephyr(1)
+client. It is responsible for receiving selected zephyr notices on
+behalf of the user, formatting them, and displaying them using
+one or more of the output devices.
+
+.SS "Selection of Zephyr Notices"
+.PP
+.I Zwgc
+subscribes to various notice classes and instances on behalf of the
+user. Only notices in the subscription list will be received. The
+subscription list is composed of the default subscriptions (stored on
+the server), the user's subscriptions file, and any subscriptions made
+using
+.IR zctl (1).
+The user's subscription file defaults to
+.IR $HOME/.zephyr.subs ,
+or it can be specified with the \-subfile
+option. If "\-" is specified as the subscription filename, the
+subscriptions will be read from standard input.
+
+.PP
+The
+.I zctl
+command is used to manipulate and change subscriptions. See the
+.IR zctl (1)
+man page for details.
+
+.SS "Zephyr Description Files"
+.PP
+.I Zwgc
+formats its output messages according to the commands in its
+description file. The user's description file
+.RI ( $HOME/.zwgc.desc
+by default, or whatever is specified by -f) is read, or the system file
+is read if the user's does not exist.
+.PP
+Every time a notice is received,
+.I zwgc
+runs through the description file, and executes the appropriate commands.
+
+.SS "Zephyr Description File Syntax"
+.PP
+A description file is simply a list of commands. Whitespace (spaces,
+tabs, and line breaks) is used
+to separate tokens. The type and amount of whitespace separating tokens
+is irrelevant.
+Comments can be delimited by # and newline (for line-oriented comments,
+e.g. "# this is a comment" on a line by itself) or by /* and */ (e.g. "/*
+this is a comment */").
+
+.SH "DESCRIPTION LANGUAGE"
+.SS Expressions
+Expressions are used by certain commands.
+They are composed from string literals, variable references,
+function calls, and operators. Parentheses can be used anywhere in an
+expression to group expressions or increase readability.
+.PP
+String literals are specified by putting the contents in "double quotes".
+.PP
+Variables are set using the
+.B set
+command (see "COMMANDS", below). They are
+referenced in an expression by using the form
+.IR $varname .
+Some variables are set by default for each notice.
+All other variables retain their values between notice interpretations,
+so that if you set a variable, it retains that value until later
+modified.
+.PP
+Functions are called using a C-like syntax,
+\fBfname\fR(\fIexpr1\fR,\fIexpr2\fR), where
+.B fname
+is the
+function name and
+.IB expr n
+are the arguments.
+.PP
+Binary operators use infix notation, such as "a == b".
+.PP
+Some commands use an expression list (exprlist), which is simply a set
+of expressions separated by whitespace (e.g. $var1 "lit1" $var2).
+
+.SS "Default variables"
+.PP
+The following variables are always available:
+.TP 5
+.B 1, ...
+Numeric variables are assigned values corresponding to that field in the
+notice (the body of each notice is conceptually an array of fields, each
+terminated with a null character). If the number is greater than the
+number of fields actually in the notice, the value is "". For example,
+the standard zwrite messages have two fields: $1 is the signature, and
+$2 is the text of the message.
+.TP 5
+.B auth
+An indication of the authenticity of the notice. ``yes'' means the
+notice is authentic, ``no'' means it is not, and ``forged'' means that
+the message claimed to be authentic but the verification of the claim
+failed. The ``forged'' indication usually appears when a user has
+changed his Kerberos tickets with
+.IR kinit (1)
+but has not run ``zctl sub'' to
+register this change with the Zephyr servers.
+.TP
+.B class
+The class of the current notice.
+.TP
+.B date
+The date on which the notice was sent.
+.TP
+.B default
+The default output format for the current notice
+.TP
+.B error
+An error message from the port read/write commands.
+.TP
+.B fromhost
+The full name of the host from which the notice appears to have been
+sent.
+.I This is not fully reliable,
+as the information used to determine this hostname is not guaranteed to
+be correct (even for authentic messages).
+.TP
+.B fullsender
+The notice sender's name, including the zephyr realm name.

+.SS Functions
+.PP
+Following is a list of functions available for use in the description
+file.
+.TP 5
+.BI buffer ()
+The contents of the current output buffer.
+.TP
+.BI downcase (expr)
+Returns the value of \fIexpr\fR, converted to lower case.
+.TP
+.BI get (expr)
+Returns a line from the port named \fIexpr\fR. If there is no text
+waiting on the port (e.g. the program connected to the port has not
+printed any output), this function will wait until it can read a line of
+text from the port.
+.TP
+.BI getenv (expr)
+Returns the value of the environment variable \fIexpr\fR, or the empty
+string if it does not exist.
+
+.TP
+.BI lany "(expr1, expr2), " rany "(expr1, expr2)"
+Return a number of characters equal to the length of
+.I expr2
+from the beginning
+.RB ( lany )
+or end
+.RB ( rany )
+of
+.I expr1
+(e.g. lany("1234567890","foo") would return "123").
+If
+.I expr1
+is a variable reference, the variable
+is modified to remove the characters returned.
+If
+.I expr2
+is longer than
+.IR expr1 ,
+the value of
+.I expr1
+is returned (and
+.I expr1
+is set to "", if a variable).
+.TP
+.BI lbreak "(expr1, expr2), " rbreak "(expr1, expr2)"
+.I Expr2
+defines a set of characters. The function returns the longest
+initial
+.RB ( lbreak )
+or final
+.RB ( rbreak )
+string from
+.I expr1
+composed of characters
+.I not
+in this set (e.g. lbreak("characters", "tuv") would return "charac"). If
+.I expr1
+is a variable reference, the variable
+is modified to remove the characters returned. If no characters
+in
+.IR expr2 " are in " "expr1, " then " expr1 "
+is returned (and
+.I expr1
+is set to "", if a variable).
+.TP
+.BI lspan "(expr1, expr2), " rspan "(expr1, expr2)"
+These functions are the negation of the
+.B break
+functions; the returned string consists of characters
+.I in
+the set defined by
+.I expr2
+.TP
+.BI protect (expr)
+Returns a string which will be evaluated identically to \fIexpr\fR,
+but will not affect any surrounding environments. That is, any
+characters which could close outside environments are quoted, and any
+environments in \fIexpr\fR which are not closed at the end are closed.
+.TP
+.BI substitute (expr)
+Evaluates variable references of the form \fI$variable\fR in expr and
+converts $$ to $.
+.TP
+.BI upcase (expr)
+Returns the value of \fIexpr\fR, converted to upper case.
+.TP
+.BI verbatim (expr)
+Returns a string that will be displayed exactly as \fIexpr\fR looks.
+Anything which could be mistaken for an environment is quoted.
+.TP
+.BI stylestrip (expr)
+Returns \fIexpr\fR with all environments stripped out.
+.TP
+.BI zvar (expr)
+Returns the value of the zephyr variable \fIexpr\fR,
+or the empty
+string if it does not exist. [Zephyr variables
+can be set and examined with
+.IR zctl (1).]
+
+.SS Operators
+.PP
+Following is a list of operators which can be used in the description
+file to compose expressions:
+.TP
+.IB expr1 " + " expr2
+String concatenation of
+.IR expr1 " and " expr2
+.TP
+.IB expr1 " == " expr2
+True if the two expressions are equal, false otherwise.

+
+.SS Commands
+.PP
+Following is a list of the commands usable in the description
+language:
+.TP 5
+.BI appendport " expr1 expr2"
+Creates a port called \fIexpr1\fR. All output to the port will be
+appended to the file \fIexpr2\fR. There is no input. If the file is
+created, its mode is set to read-write, owner only (no access for others).
+.TP
+.B break
+Exits the innermost if, case, or while block.
+.TP
+\fBcase \fIexpr1\fR [ ((\fBmatch \fIexpr\fR [,\fIexpr ...\fR]) | \fBdefault\fR)\fI commands \fR] ... \fBendcase\fR
+Evaluates \fIexpr1\fR. Then, each of the match expressions is
+evaluated in order. The first time an expression matches \fIexpr1\fR,
+then the body of commands under it is executed, and the rest of the case
+statement is skipped. This compare is case-insensitive. default always
+matches, so it should always appear as the last set of commands. See
+the default description file for an example of use.
+.TP
+.B clearbuf
+Clears the output buffer (see below for details on buffering).
+.TP
+.BI closeinput " expr"
+Closes the file associated with \fIexpr\fR.
+.TP
+.BI closeoutput " expr"
+Sends an EOF (end-of-file) to the process if \fIexpr\fR was a port created by
+execport, or closes the file if it was created by outputport or
+appendport.
+.TP
+.BI closeport " expr"
+Closes both input and output of \fIexpr\fR as defined above.
+.TP
+.BI fields " variable1 ..."
+sets the list of variables to be equal to the fields in the
+notice. If there are more variables than fields, the extra
+variables are left empty.
+.TP
+.BI exec " exprlist"
+Executes a program without any input or output. A command named by
+\fIexprlist\fR is executed. Each expression is used as an argument to
+the program; the first expression names the program (it may be either an
+absolute pathname, or a program name; the user's PATH is searched to
+find simple program names).
+.TP
+.BI execport " expr1 exprlist"
+Creates a port called \fIexpr1\fR. A command named by \fIexprlist\fR
+is executed, as described above for \fBexec\fR.
+All output to the port is sent to the standard input
+of the process. Reading from the port will return the standard output
+of the process.
+.TP
+.B exit
+Completes processing of the current notice. The remainder of the
+description file is ignored after execution of this command.
+.\" hack because the following line otherwise breaks because it is too long.
+.TP
+\fBif \fIexpr1 \fBthen \fIcommands1\fR [\fBelseif \fIexpr2 \fBthen \fIcommands2\fR] ... [\fBelse \fIcommandsn\fR] \fBendif\fR
+If \fIexpr1\fR evaluates to true, execute \fIcommands1\fI, etc. [A conditional
+construct, similar to the constructs in the C shell (csh).]
+.TP
+.BI inputport " expr1 expr2"
+Creates a port called \fIexpr1\fR. All input from the port comes from
+the file \fIexpr2\fR. There is no output.
+.TP
+.B noop
+does nothing
+.TP
+.BI outputport " expr1 expr2"
+Creates a port called \fIexpr1\fR. The file \fIexpr2\fR will be
+truncated, or created if it does not exist. All output to the port
+will be appended to the file \fIexpr2\fR. There is no input. If the file is
+created, its mode is set to read-write, owner only (no access for others).
+.TP
+.BI print " expr1 ..."
+adds the values of the expressions to the current output buffer. The
+values of the expressions are separated by spaces in the output.
+.TP
+.B put \fR[\fIexpr \fR[\fIexprlist\fR]]
+Sends data to a port. If \fIexpr\fR is provided, then it is used as the
+port, otherwise the port used is the
+port corresponding to the default output device.
+If \fIexprlist\fR is provided, the expressions in the list are sent to
+the port, separated by spaces. If it is omitted, then the contents
+of the output buffer are sent as the data.
+.TP
+.BI set " variable " = " expr"
+sets
+.I variable
+equal to
+.IR expr .
+Variable can later be
+referenced by
+.IR $variable .
+.TP
+.BI show " text " endshow
+Appends text to the output buffer. This command is special, because
+the string does not need to be quoted. Whitespace at the beginning or
+end of the lines of text is ignored. The \fIendshow\fR must appear as
+the first token on a line (it may only be preceded on that line by whitespace).
+Variable substitutions and formatting commands
+(but not expressions or functions) are processed in the text. Example:
+.nf
+show
+ this is some text
+ from: $sender
+endshow
+.fi
+.TP
+.BI while " expr " do " statements " endwhile
+Executes \fIstatements\fR until \fIexpr\fR is false.
+
+.SH PORTS
+.PP
+Ports are an abstraction encompassing all I/O forms of which
+zwgc is capable. There are pre-existing output ports corresponding to each
+of the output devices, and more ports can be created with the
+port commands described above.
+
+.SH OUTPUT
+The output is usually collected in the
+.I "output buffer"
+and saved until a
+.I put
+command sends the output to an output device (such as an X display or a
+terminal). The output buffer is implicitly cleared after each notice is
+completely processed.
+
+.PP
+Output devices are implemented as output ports. A message is
+displayed in a device-dependent manner when a string is output to the
+port corresponding to the output device. Formatting commands are
+embedded in the text as @ commands of the form @command(text).
+Command names are case-insensitive and consist of alphanumeric
+characters and underscores. Valid brackets are () [] {} and <>.
+If the command name is empty (such as in
+.RB `` @(foo) ''),
+then a new
+environment with no changes is created (This is useful to temporarily
+change some parameter of the output, such as the font).
+.PP
+The following output devices are supported:
+.TP 5
+stdout
+Sends the string to standard output exactly as is.
+.TP
+stderr
+Sends the string to standard error exactly as is.
+.TP
+plain
+Sends the string with all formatting environments removed to standard
+output.
+.TP
+tty
+Does formatting on the message according to @ commands embedded in the
+text. The output,
+with appropriate mode-changing sequences, is sent to the standard output.
+The appropriate characteristics of the display are taken from
+the TERMCAP entry (see
+.IR termcap (5))
+for the terminal named by the TERM environment variable.
+Supported @ commands are:
+.RS 10
+.TP 15
+@roman
+Roman (plain) letters (turns off all special modes).
+.TP
+@b or @bold
+Bold letters. If not available, reverse video, else underline.

+@font
+sets the current font to the font specified in the contents of the
+environment (e.g. @font(fixed)). This will remain in effect for the
+rest of the environment (a temporary change can be achieved by enclosing the
+font-change in an @(...) environment). If the named font is not
+available, the font ``fixed'' is used instead.
+.TP
+@color
+sets the color to the color specified in the contents of the
+environment. The color name should appear in the X color name database.
+This color will remain in effect for the rest of the environment. If
+the named color is not available, the default foreground color is used.
+.RE
+.IP "" 5
+Any other environment name not corresponding to the above environment
+names will set the current ``substyle.''

+.IP
+The style is specific to each window. Its name has three dot
+(``.'') separated fields, which are by default the values of the class,
+instance, and recipient variables, with all dots changed to underscores
+(``_'') and all letters converted to lowercase. The style can be

+.TP
+geometry
+Primary POSITION (not size) geometry specifier.
+The geometry should be of the form "{+|\-}x{+|\-}y", specifying an (x,y)
+coordinate for a corner of the window displaying the notice. The
+interpretation of positive and negative location specifications follows
+the X conventions. A special location of `c' for either x or y
+indicates that the window should be centered along that axis. Example:
+a geometry of "+0+c" specifies the window should be at the top of the
+screen, centered horizontally.
+.TP
+Geometry
+Secondary position specifer. [+0+0 is the default if neither is set.]
+.TP
+resetSaver
+(logical) Primary value to force screen to unsave when a message first
+appears.
+.TP
+ResetSaver
+(logical) Secondary value to force screen to unsave. [default True]
+.TP
+reverseStack
+(logical) Primary value to specify that zwgc should attempt to stack
+WindowGram windows such that the oldest messages
+normally show on top. Some X window managers may silently ignore
+.IR zwgc 's
+attempts to restack its windows. This option can cause some unusual
+interactions with other windows if the user manually restacks either the

+.TP
+ReverseStack
+Secondary value to enable reverse stacking. [default False]
+.TP
+title
+(string) Primary window title
+.TP

+Secondary window title [defaults to the last pathname component
+of the program name, usually "zwgc"]
+.TP
+transient
+(logical) Primary value which determines if zephyrgram windows will be
+created with the \fBWM_TRANSIENT_FOR\fR property set. If this
+resource is true, the property will be set, telling certain
+windowmanagers to treat zephyrgram windows specially. For instance,

+Secondary transient determining value [default False]
+.TP
+allDesktops
+(logical) Primary value which determines if zephyrgram windows should
+appear on all desktops, for those window managers which support multiple
+desktops (sometimes referred to as workspaces). When this resource is
+true (the default),
+.I zwgc
+sets the \fB_NET_WM_DESKTOP\fR property to 0xFFFFFFFF for each zephyrgram

+.TP
+minTimeToLive
+Primary value which specifies the minimum amount of time (``minimum time to

+The window class is always "Zwgc".
+.SH X BUTTONS
+.PP
+Clicking and releasing any button without the shift key depressed while
+the pointer remains inside a WindowGram window will cause it to
+disappear. If the pointer leaves the window
+while the button is depressed, the window does not disappear; this
+provides a way to avoid accidentally losing messages.
+.PP
+If the control button is held down while clicking on a WindowGram,
+then that WindowGram and all windowgrams under the point where the
+button is released will be erased.
+.PP
+.B WARNING:
+If you do this with too many WindowGrams under the mouse, it is
+possible for your subscriptions to be lost. If \fIzctl retrieve\fR
+returns nothing, then issue a \fIzctl load\fR command to re-subscribe
+to your default set of subscriptions. If you use znol, then \fIznol
+-q &\fR will restore the subscriptions you need for \fIznol\fR.
+.PP
+Portions of the text of a message may be selected for "pasting" into other X
+applications by using the shift key in cooperation with the pointer
+buttons.
+Holding the Shift key while depressing Button1 (usually the left button)
+will set a marker at the
+text under the pointer. Dragging the pointer with Shift-Button1 still
+depressed extends the selection from the start point, until the button
+is released. The end of the selection may also be
+indicated by releasing Button1, holding down the Shift key, and pressing
+Button3 (usually the right button) at the desired endpoint of the selection.
+The selection will appear with the text and background colors reversed.
+
+.SH ADDITIONAL X FEATURES
+If
+.I zwgc
+receives a WM_DELETE_WINDOW, it destroys the zephyrgram as if it were
+clicked on.
+.PP
+If a zephyrgram is unmapped, it is removed from the stacking order
+used by reverseStack.
+
+.SH COMMAND LINE
+.I zwgc
+is normally invoked from
+.IR /usr/athena/lib/init/login ,
+.IR $HOME/.xsession ,
+or
+.I /usr/athena/lib/init/xsession
+in the foreground. When it has successfully set your location and
+obtained subscriptions, it will put itself into the background (unless
+the \-nofork option has been specified). At this point it is safe to
+invoke additional zephyr commands, such as
+.IR znol (1).
+(You can also put these commands in the
+.I initprogs
+Zephyr variable; the value of this variable is passed as the argument to
+the
+.IR system (3)
+library call during initialization.)
+.I zwgc
+will exit with an exit
+status of 0 if it was able to open the X display successfully or 1 if it
+couldn't open the display and the Zephyr variable
+.I fallback
+was set to ``false''. If
+.I fallback
+is set to ``true'',
+.I zwgc
+will fall back to ``ttymode'' (making the tty driver the default output
+device) if it can't open the X display. If
+.I fallback
+is not set and the display cannot be opened,
+.I zwgc
+prints an explanatory message and exits with a status of 1.
+.PP
+If the
+.I \-ttymode
+option is specified,
+.I zwgc
+will ignore any X display and use the terminal as its primary output
+device. This flag overrides any setting of the fallback variable.
+.PP
+If the
+.I \-loc
+option is specified,
+.I zwgc
+will use the specified string as the tty field for the location it
+sets. This allows users to potentially specify more useful auxiliary
+information than their ttys or display names.
+.PP
+The
+.I \-reenter
+option is provided for compatibility with the previous version of
+.IR zwgc .
+.PP
+.I zwgc
+will exit cleanly (unset location and cancel subscriptions) on:
+.nf
+ SIGTERM
+ SIGHUP
+ XIOError (with a message to stderr)
+.fi
+SIGHUP is what it expects to get upon logout. Also, the signals
+SIGINT, SIGQUIT, and SIGTSTP are ignored because they can be sent
+inadvertently, and bizarre side-effects can result. If you want them
+to be acted on, then run
+.I zwgc -nofork &
+.PP
+If
+.I zwgc
+receives a SIGUSR1, it will rewrite the file used to store the

+For an example of a description file, see
+.IR /usr/athena/share/zephyr/zwgc.desc .
+For an example of X resources, see
+.IR /usr/athena/share/zephyr/zwgc_resources .
+
+.SH BUGS
+The X selection code can highlight the wrong portions of messages
+containing formatted text placed with the @center() or @right()
+directives.
+.PP
+If you are using Kerberos support and get new tickets (using
+``kinit''), you must send a subscription notice to the server (using a
+command such as ``zctl load /dev/null'') or all received Zephyr
+notices will appear to be unauthentic. (If all received Zephyr
+notices appear to be forged, your tickets have probably expired, in
+which case you must get new tickets and then run ``zctl load
+/dev/null''.)

+#
+# $auth can be either Yes, No, or Forged

+# "Yes" means that the sender field present in the notice was verified by

+#
+# "No" means that either the sender did not include any authentication
+# information, or the authentication information was not verified by the
+# Zephyr Server before the notice was sent to you.
+#
+# "Forged" means that the Server claims that the sender of the notice
+# was verified by Kerberos authentication, but your WindowGram client
+# could not verify this. This stage of verification is done by a cryptographic
+# checksum. The most probable cause of the failure of the checksum
+# provided by the Server to match the checksum generated by your
+# WindowGram client is that you changed Kerberos tickets, and the Server
+# was using an old value to compute the cryptographic checksum. You can
+# update the Server's value by typing 'zctl load' to your prompt.
+#
+# By default, notices which appear forged are labeled as 'UNAUTHENTIC'
