+xpaaccess returns \*(L"yes\*(R" to stdout (with a return error code if 1) if there are
+existing \s-1XPA\s0 access points that match the 
+template
+(and optional access type: g,i,s). Otherwise, it returns \*(L"no\*(R" (with a
+return error code of 0).  If \-n is specified, the number of matches is
+returned instead (both to stdout and in the returned error code). If
+\&\-v is specified, each access point is displayed to stdout instead of
+the number of matches.
+.PP
+By default, xpaaccess simply contacts the xpans name server to find
+the list of registered access points that match the specified
+template. It also checks to make sure the specified types are
+supported by that access point. This is the fastest way to determine
+available access points. However, an access point might registered but
+not yet available, if, for example, the server program has not entered
+its event loop to process \s-1XPA\s0 requests. To find access points that are
+guaranteed to be available for processing, use the \-c (contact)
+switch.  With this switch, xpaaccess contacts each matching \s-1XPA\s0 server
+(rather than the name server) to make sure the registered access point
+really is ready for processing. In this mode, if an access point is
+registered but not available, xpaaccess will pause for a period of
+time equal to the \s-1XPA_LONG_TIMEOUT\s0, in order to give the server a
+chance to ready itself. By default, this timeout is 30 seconds. You
+can shorten the time of delay using the \-t \*(L"short,long\*(R" switch. For
+example, to shorten the delay time to 2 seconds, use:
+.PP
+.Vb 1
+\&  xpaaccess \-c \-t "2,2" ds9
+.Ve
+.PP
+The first argument is the short delay value, and is ignored in this
+operation. The second is the long delay timeout.
+.PP
+Note also that the default xpaaccess method (no \-c switch) does not
+check access control (acls) but rather only checks whether the access
+point is both registered with the xpans name server and provides the
+specified type of access. In other words, the default xpaaccess could
+return 'yes' when you might not actually have access. This mode also
+always returns 'yes' for the xpans name server itself, regardless of
+whether the name server is active. The \-c (contact) switch, which
+contacts the access point directly, can and does check the access
+control (only for servers using version 2.1 and above) and also
+returns the real status of xpans.

+This document describes changes that will affect users who migrate

+.SH "DESCRIPTION"
+.IX Header "DESCRIPTION"
+There have been a few changes that affect users who upgrade \s-1XPA\s0
+from version 1.0 to version 2.0.  These changes are detailed below.
+.IP "\(bu" 4
+\&\s-1XPA\s0 commands no longer have a resolver routine (this is open to
+negotiations, but we decided the idea was dumb).  For the SAOtng
+program, this means that you must explicitly specify the access
+point, i.e.,:
+.Sp
+.Vb 1
+\&  cat foo.fits | xpaset SAOtng fits
+.Ve
+.Sp
+instead of:
+.Sp
+.Vb 1
+\&  cat foo.fits | xpaset SAOtng
+.Ve
+.IP "\(bu" 4
+By default, xpaset, xpaget, etc. now wait for the server callback to
+complete; i.e., the old \-W is implied (and the switch is ignored).
+This allows support for better error handling.  If you want xpaset, etc.
+to return before the callback is complete, use \-n switch:
+.Sp
+.Vb 1
+\&  echo "file foo.fits" | xpaset \-n SAOtng
+.Ve
+.IP "\(bu" 4
+The old \-w switch in xpaset and xpaget is no longer necessary (and is
+ignored), since you can have more than one process communicating with
+an xpa access point at one time.
+.IP "\(bu" 4
+The new \-p switch on xpaset means you need not read from stdout:
+.Sp
+.Vb 1
+\&  xpaset \-p SAOtng colormap I8
+.Ve
+.Sp
+will send the paramlist to the SAOtng callback without reading from stdin.

+.SH "NAME"
+xpamb: the XPA Message Bus
+.SH "SYNOPSIS"
+.IX Header "SYNOPSIS"
+The xpamb program can act as a \*(L"classical\*(R" message bus interface
+between clients and servers. A client can send a data request to
+the message bus, which then interfaces with multiple servers and
+returns the data back to the client.
+.SH "OPTIONS"
+.IX Header "OPTIONS"
+For xpaset, several optional switches are used to save data and
+manipulate the stored data:
+.IP "\(bu" 4
+\&\fB\-data [name]\fR
+.Sp
+Add the supplied data buffer to a pool of stored data buffers,
+using the specified name as a unique identifier for later retrieval.
+An error occurs if the name already exists (use either \fBreplace\fR
+or \fBdel\fR to rectify this). The \fB\-add\fR switch is supported
+for backwards compatibility with xpa 2.0.
+.IP "\(bu" 4
+\&\fB\-replace [name]\fR
+.Sp
+Replace previously existing stored data having the same unique name
+with new data. This essentially is a combination of the \fBdel\fR
+and \fBdata\fR commands.
+.IP "\(bu" 4
+\&\fB\-info [\*(L"'info string'\*(R"]\fR
+.Sp
+When adding a data buffer, you can specify an informational
+string to be stored with that data.  This string will be returned
+by xpaget:
+.Sp
+.Vb 1
+\&  xpaget xpamb foo \-info
+.Ve
+.Sp
+(along with other information such as the date/time of storage and the size of
+the data buffer) if the \-info switch is specified. If the info string contains
+spaces, you must enclose it in \fBtwo\fR sets of quotes:
+.Sp
+.Vb 1
+\&  cat foo | xpaset xpamb \-data foo \-info "\*(Aqthis is info on foo\*(Aq"
+.Ve
+.Sp
+The first set of quotes is removed by the shell while the second is used to
+delineate the info string.
+.IP "\(bu" 4
+\&\fB\-send [name]\fR
+.Sp
+Broadcast the stored data buffer to the named template.
+.IP "\(bu" 4
+\&\fB\-del [name]\fR
+.Sp
+Delete the named data buffer and free all allocated space.
+.PP
+Switches can be used in any combination that makes sense. For example:
+.PP
+.Vb 1
+\&  cat foo.fits | xpaset xpamb \-data foo \-info "FITS" "DS9:*" fits foo.fits
+.Ve
+.PP
+will broadcast the foo.fits image to all access points of class
+\&\fB\s-1DS9\s0\fR.  In addition, the foo.fits file will be stored under the
+name of \fBfoo\fR for later manipulation such as:
+.PP
+.Vb 1
+\&  xpaset \-p xpamb \-send foo "DS9:*" fits foo.fits
+.Ve
+.PP
+will re-broadcast the foo.fits image to all access points of class \*(L"\s-1DS9\*(R".\s0
+.SH "DESCRIPTION"
+.IX Header "DESCRIPTION"
+A \*(L"classical\*(R" message bus (such as ToolTalk) consists of servers and
+clients, along with a mediating program that transfers data between
+different processes. \s-1XPA\s0 takes a slightly different approach in that
+communication between clients and servers is direct.  This generally
+is the correct technique when there is only one connection (or even a
+small number of connections), but can become inefficient for the
+serving program if a large amount of data is being transferred to many
+clients. For example, if a real-time data acquisition program is
+broadcasting a \s-1FITS\s0 image to several clients, it would need to
+transmit that image to each client individually.  This might interfere
+with its own processing cycles.  The preferable mechanism would be to
+pass the image off to an intermediate program that can then broadcast
+the data to the several clients.
+.PP
+The \fBxpamb\fR program can alleviate such problems by functioning
+as a message bus in cases where such an intermediary process is
+wanted.  It pre-defines a single access point named
+\&\fBXPAMB:xpamb\fR to which data can be sent for re-broadcast. You
+also can tell \fBxpamb\fR to save the data, and associate with that
+data a new access point, so that it can be retrieved later on.
+.PP
+All interaction with \fBxpamb\fR is performed through
+\&\fBxpaset\fR and \fBxpaget\fR (or the corresponding \s-1API\s0
+routines, \fB\f(BIXPASet()\fB\fR and \fB\f(BIXPAGet()\fB\fR) to the
+\&\fBXPAMB:xpamb\fR access point. That is, \fBxpamb\fR is just
+another XPA-enabled program that responds to requests from
+clients. The paramlist is used to specify the targets to which
+the data will be for re-broadcast, as well as the re-broadcast paramlist:
+.PP
+.Vb 1
+\&  data | xpaset xpamb [switches] broadcast\-target broadcast\-paramlist
+.Ve
+.PP
+Optional switches are used to store data, and manipulate stored data,
+and are described below.
+.PP
+In its simplest form, you can, for example, send a \s-1FITS\s0 image to xpamb for
+broadcasting to all ds9 image simply by executing:
+.PP
+.Vb 1
+\&  cat foo.fits | xpaset xpamb "DS9:*" fits foo.fits
+.Ve
+.PP
+Since \fB\s-1DS9\s0\fR is the class name for the ds9 image display
+program, this will result in the \s-1FITS\s0 image being re-sent to all fits
+access points for all active image display programs.
+.PP
+You can send stored data and new data to the same set of access points at
+the same time.  The stored data always is sent first, followed by the new
+data:
+.PP
+.Vb 1
+\&  cat foo2.fits | xpaset xpamb \-send foo "DS9:*" fits foo.fits
+.Ve
+.PP
+will first send the foo.fits file, and then the foo2.fits file to all
+access points of class \fB\s-1DS9\s0\fR.  Notice that in this example,
+the foo2.fits file is not stored, but it could be stored by using the
+\&\fB\-store [name]\fR switch on the command line.
+.PP
+The \fBxpaget\fR command can be used to retrieve a data from \s-1XPA\s0
+access points or from a stored data buffer, or retrieve information
+about a stored data buffer.  If no arguments are given:
+.PP
+.Vb 1
+\&  xpaget xpamb
+.Ve
+.PP
+then information about all currently stored data buffers is returned. This
+information includes the data and time at which the data was stored, the
+size in bytes of the data, and the supplied info string.
+.PP
+If arguments are specified, they will be in the form:
+.PP
+.Vb 1
+\&  xpaget xpamb [\-info] [\-data] [name [paramlist]]
+.Ve
+.PP
+If the optional \fB\-info\fR and/or \fB\-data\fR switches are specified, then
+information and/or data will be returned for the named data buffer
+following the switches. You can use either or both of these switches
+in a single command. For example, if the \-info switch is used:
+.PP
+.Vb 1
+\&  xpaget xpamb \-info foo
+.Ve
+.PP
+then the info about that stored data buffer will be returned.
+If the \-data is used with a specific name:
+.PP
+.Vb 1
+\&  xpaget xpamb \-data foo
+.Ve
+.PP
+then the stored data itself will be returned. If both are used:
+.PP
+.Vb 1
+\&  xpaget xpamb \-info \-data foo
+.Ve
+.PP
+then the info will be returned, followed by the data. Note that it is an
+error to specify one of these switches without a data buffer name and that
+the paramlist will be ignored.
+.PP
+If neither the \fB\-info\fR or \fB\-data\fR switch is specified, then
+the name refers to an \s-1XPA\s0 access point (with an optional paramlist
+following).
+For example:
+.PP
+.Vb 1
+\&  xpaget xpamb ds9 file
+.Ve
+.PP
+is equivalent to:
+.PP
+.Vb 1
+\&  xpaget ds9 file

+.SH "DESCRIPTION"
+.IX Header "DESCRIPTION"
+The xpans name server is an XPA-enabled program that is used to
+manage the names and ports of \s-1XPA\s0 access points. It is started
+automatically when an \s-1XPA\s0 access point is registered. You can access
+the name server using xpaget to get a list of registered access points.
+.PP
+The \fIxpans\fR name server provides a crucial link between \s-1XPA\s0
+clients and servers.  When an \s-1XPA\s0 server defines an access point using
+\&\fIXPANew()\fR, \fIXPACmdNew()\fR, or \fIXPAInfoNew()\fR, the name of the access point
+is registered in the name service, along with connection information.
+The name server then matches class:name templates passed to it by \s-1XPA\s0
+clients with these registered entries, so that the clients can
+communicate with the appropriate servers.
+.PP
+The socket connection between an XPA-enabled program and
+\&\fIxpans\fR is kept open until the former exits (or explicitly
+closes the connection). Apparently, some Internet equipment (e.g. \s-1DSL\s0
+modems) can cause such a connection to time-out after a period of
+inactivity. To prevent this from happening, you can use the \-k
+[sec] switch to send a short keep-alive message to each open
+connection after the specified time delay. (Note that this
+application level use of keep-alive is necessary only if you are
+serving XPA-enabled clients over the Internet and have to deal with
+long-term connections involving \s-1DSL\s0 or similar equipment.  \s-1XPA\s0 uses
+the ordinary socket-level keep-alive, which works for all other cases.)
+\&\s-1NB\s0 (12/2/2009): Out-of-band (\s-1URG\s0) \s-1TCP\s0 data, used by xpans
+keep-alive, is changed by some Cisco routers into in-band data.
+Encountering such a router will break the keep-alive function and may
+break your \s-1XPA\s0 server as well. Proceed with caution!
+.PP
+The \fIxpans\fR program will be started automatically (assuming it
+can be found in the user's path) when the first \s-1XPA\s0 access point is
+registered.  It therefore need not be started explicitly.  However,
+when started automatically, the \fI\-e\fR switch is used, so that
+the name server will exit when there are no more \s-1XPA\s0 access points
+registered. If you wish to keep the name server running continually,
+simply start it manually without the \fI\-e\fR switch.
+.PP
+The name server will keep a log of registered access points if the
+\&\fI\-l [log]\fR switch is used on the command line (this is the
+case for automatic start-up).  The log contains enough name and connection
+information to allow you to re-register all \s-1XPA\s0 access points in case
+the name server process is terminated prematurely. For example, after
+the ds9 access point is registered,the log will contain the entry:
+.PP
+.Vb 1
+\&  add 838e2f67:1863 ds9 ds9 gs eric
+.Ve
+.PP
+If \fIxpans\fR is terminated but ds9 still is running, you
+can re-register both access points for the ds9 process by running:
+.PP
+.Vb 1
+\&  xpaset \-p 838e2f67:1863 \-nsconnect
+.Ve
+.PP
+Notice that the ip:port specifier is used with \fIxpaset\fR to bypass
+the need for contacting the name server (which does not have the name
+registered yet!)
+.PP
+The name server will keep a log of security information if the \-s
+[security log] switch is used on the command line. For each
+accepted connection, (including connections via the \fIxpaget\fR
+command), information will be logged about the host issuing the
+command and the parameters passed into the program. This is most
+useful when \fIxpans\fR is accepting connections from untrusted
+machines.
+.PP
+When an \s-1XPA\s0 access point is removed by a server using \fI\fIXPAFree()\fI\fR,
+the access information is removed from the name server.  If an
+XPA-enabled process is terminated, all names registered by that process
+will be removed automatically.  The log file is always updated to
+reflect the currently registered access points.
+.PP
+The name server itself has an \s-1XPA\s0 access point names \fIxpans\fR
+registered through which you can find out information about currently
+registered access points (assuming you have access to the name server;
+see \s-1XPA\s0 Access Control for more information).
+For each registered access point, the following information is returned:
+.PP
+.Vb 5
+\&  class         # class of the access point
+\&  name          # name of the access point
+\&  access        # allowed access (g=xpaget,s=xpaset,i=xpainfo)
+\&  id            # socket access method (host:port for inet, file for local/unix)
+\&  user          # user name of access point owner
+.Ve
+.PP
+For example, to display all currently registered access points, simply execute:
+.PP
+.Vb 1
+\&  xpaget xpans
+.Ve
+.PP
+Continuing the example of ds9 above, this will return:
+.PP
+.Vb 1
+\&  DS9 ds9 gs 838e2f67:1863 eric
+.Ve
+.PP
+If the same program has been started with different \s-1XPA\s0 access names,
+you can look up only names matching a specified template. For example,
+assume that ds9 has been started up using:
+.PP
+.Vb 3
+\&  ds9 &
+\&  ds9 \-title ds9\-1\-eric &
+\&  ds9 \-title ds9\-2\-eric &
+.Ve
+.PP
+To lookup all ds9 access points which end in \*(L".eric\*(R" and which can
+be accessed using \fIxpaset\fR, use:
+.PP
+.Vb 1
+\&  xpaget xpans "DS9:*.eric" "s" "*"
+.Ve
+.PP
+This will return:
+.PP
+.Vb 2
+\&  DS9 ds9\-2\-eric gs 838e29d3:42102 eric
+\&  DS9 ds9\-1\-eric gs 838e29d3:42105 eric
+.Ve
+.PP
+The third argument \*(L"*\*(R" requests all access points from all users.
+You also can specify a specific user name and only access points
+registered by that user will be returned.
+.PP
+The name server uses the \fI\s-1XPA_METHOD\s0\fR environment variable
+to determine whether it should listen for requests on \s-1INET\s0 or \s-1LOCAL\s0
+sockets.  Since \s-1XPA\s0 access points also use this environment variable,
+the choice of socket method will be consistent.  Note that, when \s-1INET\s0
+sockets are used, a local server can be accessed from remote machines
+if the \fI\s-1XPA_NSINET\s0\fR environment variable is set to point to
+the local machine.  See
+\&\s-1XPA\s0 Environment Variables
+for more information.
+.PP
+An experimental feature of xpans is its ability to act as a proxy to
+\&\s-1XPA\s0 servers behind firewalls that want to communicate with external
+processes.  The basic idea is the following: an \s-1XPA\s0 server (call it
+\&\*(L"foo\*(R") on host1, possibly behind a firewall, makes a remote connection
+to a proxy-enabled xpans program on host2 (specifying host2's \s-1XPA\s0 method).
+For example:
+.PP
+.Vb 1
+\&  xpaset \-p foo \-remote \*(Aqhost2:28571\*(Aq + \-proxy   # on host1
+.Ve
+.PP
+When this is done, host2 can use xpaset, xpaget, and xpainfo calls to
+communicate with the \s-1XPA\s0 server foo. All command communication is
+performed via the xpans socket connection between foo on host1 and
+xpans on host2 (which was initiated by foo from inside the firewall).
+Data communication is similarly performed using a socket connection
+initiated on host1 (usually with a port value two greater than the
+port value of the main xpans socket connection). An xpaset or xpaget
+call on host2 contacts xpans, which performs an \fIXPASet()\fR or \fIXPAGet()\fR
+call to foo, passing commands and data back and forth between the two
+programs.
+.PP
+By default, proxy connections are not allowed by xpans. If the \-P switch is
+specified with a value of 1, proxy connection are allowed, but all proxy
+communication is performed in the same thread as xpans processing. If
+a value of 2 is specified, the proxy processing is performed in a
+separate thread (assuming pthreads are supported on your system).
+Because xpa callback processing of any type can take a long time and
+therefore can interfere with normal xpans processing, threaded proxy
+connections (\-P 2) are recommended.  When using proxy connections, it
+might also be useful to set the \s-1XPA_IOCALLSXPA\s0 environment variable, so
+that multiple proxy requests can be handled at the same time, instead of
+serially.
+.PP
+Note that this proxy interface to xpans is experimental. It is used
+to provide remote data analysis capabilities on the Chandra-Ed system
+using ds9.  (See http://chandra\-ed.cfa.harvard.edu and
+http://hea\-www.harvard.edu/saord/ds9 for more details). As always, please
+contact us if you have problems or questions.

+Data read from stdin will be sent to access points matching the

+or host:port.
+A set of qualifying parameters can be appended.
+.PP
+Normally, xpaset reads data input from stdin until \s-1EOF\s0 and sends those
+data to the \s-1XPA\s0 target, along with parameters entered on the command
+line. For example to send a \s-1FITS\s0 file to the ds9 image display:
+.PP
+.Vb 1
+\&  cat foo.fits | xpaset ds9 fits
+.Ve
+.PP
+Sometimes, however, it is desirable to send only parameters to an \s-1XPA\s0
+access point, without sending data. For such cases, use the \-p switch to
+indicate that there is no data being send to stdin. For example, to
+change the colormap used by the ds9 image display program, use:
+.PP
+.Vb 1
+\&  csh> xpaset \-p ds9 cmap Heat
+.Ve
+.PP
+Of course, this also can be accomplished by sending \s-1EOF\s0 to stdin in
+any of the usual ways:
+.PP
+.Vb 4
+\&  csh> echo "" | xpaset ds9 cmap Heat
+\&  csh> xpaget ds9 cmap Heat < /dev/null
+\&  csh> xpaset ds9 cmap Heat
+\&  ^D                    # Ctl\-D signals EOF
+.Ve
+.PP
+The \-s switch puts xpaset into server mode, in which commands and data
+can be sent to access points without having to run xpaset multiple times.
+(Its not clear if this buys you much!) The syntax for sending commands
+in server mode is:
+.PP
+.Vb 8
+\&  csh> xpaset \-s
+\&  xpaset ds9 colormap I8
+\&  ^D
+\&  xpaset ds9 regions
+\&  circle 200 300 40
+\&  circle 300 400 50
+\&  ^D
+\&etc.
+.Ve
+.PP
+After the  required \*(L"xpaset\*(R" command is specified, optional \s-1ASCII\s0 data
+can be appended (as in the region example).  A single data/command set is
+delimited by ^D. Note that typing ^D when a command is expected terminates
+the program.
+.PP
+\&\s-1NB:\s0 server mode only works from the terminal and only \s-1ASCII\s0 data can be
+sent in this way.
+.PP

+\&  csh> echo "stop" | xpaset myhost:12345
