       These commands are SAMPLE CLIENTS provided with the XTrap X Server Extension Sources, Ver-
       sion 3.3.  XTrap is an X Server extension which facilitates the capturing of server proto-
       col and synthesizing core input events.	Information on how to obtain these sources can be
       found in the SOURCES section below.

       The  xtrapreset	command  is  the  simplest  XTrap  client  in  that it merely performs an
       XQueryExtension() against XTrap.  The name "reset" is historical.  The display argument is
       parsed by the X Toolkit and specifies the display where XTrap is to be loaded; see X(1).

       xtrapinfo  displays general configuration information as a result of an GetAvailable XTrap
       request to the specified server.  It is simply designed to test the request/response mech-
       anism  of  the  XTrap  extension  and  client library as well as display the configuration
       information that it finds.

       xtrapstats tests the event and request vectoring of the server  extension  by  configuring
       XTrap  to collect usage statistics on all core input events and requests.  It has a primi-
       tive command-line interface for showing the counters, zeroing out the counters, and  quit-
       ting the program.

       xtrapout  tests the output transport from the XTrap extension to the XTrap client library.
       As an aside, since xtrapout has the capability  of  "recording"	events	and  requests  it
       receives,  xtrapout  is	ideal  for providing input to test xtrapin.  Since events are the
       only concern for the input transport, the -e flag can be specified to  indicate	that  all
       input  events  (and only events) should be recorded by xtrapout.  script is specified pri-
       marily for non-U*IX machines which don't support I/O re-direction easily.  The -v flag  is
       used to force recording of all requests and input events.

       xtrapin is used to test the input transport to the XTrap server extension.  As stated ear-
       ler, it's input can be provided by xtrapout using the -e  qualifer.   While  it's  primary
       function  is  for  testing XTrap and serving as an example for XTrap functionality, it can
       reasonably used as a primitive "playback" client for X sessions.

       xtrapchar parses ANSI character sequences including application program sequences to  syn-
       thesize	input events to X Window servers using the XTrap server extension.  The intent of
       this program is to serve as a sample implementation for interfacing character-based alter-
       native  input  sources into X servers (e.g.  voice recognition systems).  Another applica-
       tion might be "remote keyboards".  The -v flag causes the program to display XTrap config-
       uration	information  and echo's characters processed to stdout.  If present, this must be
       the first argument.

       Note: xtrapchar has only been used with Digital Workstations using  the	LK201  compatible
       keyboard.   Though reasonable effort was done to maintain portability,  no claims are made
       as to the current level of portability to non-DEC servers for this program.

       The xtrapproto command is a regression test designed to	test  the  basic  XTrap  protocol
       between	a  client  and server.	If a given implementation is suspect, the results of this
       test should be sent to an XTrap implementor and/or developer.

       -d[isplay] display
	   Specifies the server to record from or playback to; see

       -e  Record only (and all) events.  Should be used when creating input for

       -f script
	   The pathname of the script to be recorded / played back.

       -v  Verbose mode.

       X Toolkit Error: Can't load DEC-XTRAP extension

       The XTrap X server extension has not been linked into the specified X server.

       Sources have been posted on UseNet systems via anonymous ftp.
       They are:

       Digital participated in the X Consortium's xtest working group which
       chose to evolve XTrap functionality into a new extension for X11/R6
       known as the RECORD extension (XTrap input synthesis functionality is
       currently covered by the XTEST extension).  It is strongly suggested
       that users of XTrap technology begin developing against RECORD/XTEST
       as it is the intention of the X Consortium to drive these two extensions
       in the standards process for providing the protocol capturing/synthesis
       functionality.  Some members of the xtest working group are actively
       researching migration issues between XTrap and RECORD.  If you'd like
       to contribute, please participate!  Contact your local X Consortium Rep
       for details on how to be added to the xtest mailing list.
