       xkbevd - XKB event daemon

       xkbevd [ options ]

       This  command is very raw and is therefore only partially implemented;  we present it here
       as a rough prototype for developers, not as a general purpose tool for end  users.   Some-
       thing  like this might make a suitable replacement for xev;  I'm not signing up, mind you,
       but it's an interesting idea.

       The xkbevd event daemon listens for specified XKB events and executes  requested  commands
       if  they  occur.   The configuration file consists of a list of event specification/action
       pairs and/or variable definitions.

       An event specification consists of a short XKB event name followed by a string or  identi-
       fier which serves as a qualifier in parentheses;  empty parenthesis indicate no qualifica-
       tion and serve to specify the default command which is applied  to  events  which  do  not
       match any of the other specifications.  The interpretation of the qualifier depends on the
       type of the event:  Bell events match using the name of the bell, message events match  on
       the  contents  of  the  message	string	and slow key events accept any of press, release,
       accept, or reject.   No other events are currently recognized.

       An action consists of an optional keyword followed by an optional string  argument.   Cur-
       rently,	xkbev  recognizes  the actions: none, ignore, echo, printEvent, sound, and shell.
       If the action is not specified, the string is taken as the name of  a  sound  file  to  be
       played  unless  it  begins with an exclamation point, in which case it is taken as a shell

       Variable definitions in the argument string are expanded with fields  from  the	event  in
       question  before the argument string is passed to the action processor.	 The general syn-
       tax for a variable is either $cP or $(str), where c is a single character  and  str  is	a
       string of arbitrary length.  All parameters have both single-character and long names.

       The  list of recognized parameters varies from event to event and is too long to list here
       right now.   This is a developer release anyway, so you can be expected	to  look  at  the
       source code (evargs.c is of particular interest).

       The  ignore,  echo,  printEvent, sound,and shell actions do what you would expect commands
       named ignore, echo, printEvent, sound, and shell to do, except that the sound command  has
       only been implemented and tested for SGI machines.   It launches an external program right
       now, so it should be pretty easy to adapt, especially if you like audio cues  that  arrive
       about a half-second after you expect them.

       The only currently recognized variables are soundDirectory and soundCmd.  I'm sure you can
       figure out what they do.

       -help   Prints a usage message that is far more up-to-date than anything in this man page.

       -cfg file
	       Specifies the configuration file to read.   If no configuration file is specified,
	       xkbevd looks for ~/.xkb/xkbevd.cf and $(LIBDIR)/xkb/xkbevd.cf in that order.

       -sc cmd Specifies the command used to play sounds.

       -sd directory
	       Specifies a top-level directory for sound files.

       -display display
	       Specifies the display to use.  If not present, xkbevd uses $DISPLAY.

       -bg     Tells xkbevd to fork itself (and run in the background).

       -synch  Forces synchronization of all X requests.  Slow.

       -v      Print more information, including debugging messages.   Multiple specifications of
	       -v cause more output, to a point.
