This parameter specifies the name of a file which, 
	if opened, will be executed by the server when the file is closed. 
	This allows a UNIX script to be sent to the Samba host and 
	executed on behalf of the connected user.
	Scripts executed in this way will be deleted upon 
	completion assuming that the user has the appropriate level 
	of privilege and the file permissions allow the deletion.
	If the script generates output, output will be sent to 
	the file specified by the 
	parameter (see above).
	Note that some shells are unable to interpret scripts 
	containing CR/LF instead of CR as 
	the end-of-line marker. Magic scripts must be executable 
	as is on the host, which for some hosts and 
	some shells will require filtering at the DOS end.
	Magic scripts are EXPERIMENTAL and 
		should NOT be relied upon.
