Readme-file for XRUN

This tool allows the user to pass varying arguments to a program
before executing it.
For exemple, if the called program is foobar.exe, the tool would
open a dialogbox:

     +---------------------------------------------+
     ! Prog : foobar.exe_______________  [  OK  ]  !
     ! Parms: /q *.pic_________________  [Cancel]  !
     +---------------------------------------------+

The user can specify any arguments, here "/q *.pic", that are
transmitted to the program before it is launched.

Installation of XRUN:
A program can be "piped" through XRUN in different ways.
In any case, it is easier if xrun.exe can be found in the path.

Method 1:
add a shortcut to xrun.exe in the SENDTO folder

Method 2:
add a registry key HKEY_CLASSES_ROOT/exefile/shell/Run/command
with default-value
  "xrun command.com /k %1"   for Win95
  "xrun %1"                  for WinNT
