**++
**  FACILITY:  xtrapout - Sample client to test output from XTrap extension
**
**  MODULE DESCRIPTION:
**
**      This is the main module for a sample/test client
**      for the XTrap X11 Server Extension.  It accepts  
**      a script output file, a transport method,
**      and an "events mode" flag (-e) as input,
**      in addition to the standard X arguments (-d, etc.).
**      If no script file is provided, stdout is the default
**      and can be piped to the companion "xtrapin"
**      client (normally used with the -e argument which  
**      sends all core input events to stdout).
**
**
**  AUTHORS:
**
**      Kenneth B. Miller
**
**  CREATION DATE:  March 28, 1990
**
**  DESIGN ISSUES:
**
**      See the companion "xtrapin" client.
**
**      Also, getopt() is used to parse the command
**      line arguments prior to calling XtAppInitialize().
**      This is because DECwindows appears to remove the user-
**      defined arguments from the argv[] vector without actually
**      acting upon them.
