55**  FACILITY:  xtrapin - Sample client to test input to XTrap extension
56**
57**  MODULE DESCRIPTION:
58**
59**      This is the main module for a sample/test client
60**      for the XTrap X11 Server Extension.  It accepts
61**      a script file and a transport method as input
62**      in addition to the standard X arguments (-d, etc.).
63**      If no script file is provided, stdin is the default
64**      and can be piped from the companion "xtrapout"
65**      client (normally used with the -e argument which
66**      sends all core input events to stdout).
67**
68**
69**  AUTHORS:
70**
71**      Kenneth B. Miller
72**
73**  CREATION DATE:  December 15, 1990
74**
75**  DESIGN ISSUES:
76**
77**      See the companion "xtrapout" client.
78**
79**      Also, getopt() is used to parse the command
80**      line arguments prior to calling XtAppInitialize().
81**      This is because DECwindows appears to remove the user-
82**      defined arguments from the argv[] vector without actually
83**      acting upon them.
