DESCRIPTION

       These  commands	are  SAMPLE CLIENTS provided with the XTrap X Server Extension Sources, Version 3.3.  XTrap is an X Server extension which
       facilitates the capturing of server protocol 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 mechanism 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 primitive command-line interface for showing the counters, zeroing out the counters, and quitting the pro-
       gram.

       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 primarily 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 earler, 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 synthesize 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 alternative
       input sources into X servers (e.g.  voice recognition systems).	Another application might be "remote keyboards".  The -v flag  causes  the
       program to display XTrap configuration 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  implementa-
       tion is suspect, the results of this test should be sent to an XTrap implementor and/or developer.

OPTIONS

       -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.

DIAGNOSTICS

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

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

IMPORTANT NOTE

       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.
