/*
 * NMPGMGRP - Tiny program to add and remove items from the program group.  
 * Its initial purpose is to support Windows NT common program groups, 
 * which are not supported by GRPCONV.
 *
 * Usage:
 *
 *  NMPGMGRP /add [/common] [/g:"<group name>"] /n:"<program name>" 
 *		/p:"<program path>"
 *  NMPGMGRP /delete [/common] [/g:"<group name>"] /n:"<program name>"
 *
 *  NMPGMGRP /i /n:"<src mnmdd.dll>" /p:"<dst mnmdd.dll>"   INSTALL NT DD
 *  NMPGMGRP /u /n:"<src mnmdd.dll>"                        UNINSTALL NT DD
 *
 *  NMPGMGRP /s [/q] /n:"<inf file>" /f"<friendly name>"			SETUP
 *
 *	/add is used to add a new program item.
 *	/delete is used to remove an existing program item.
 *
 *	/common indicates that this item belong in the common (as opposed to 
 *		per-user) program groups.
 *
 *	<group name> is the name of the program group, expressed as a pathname 
 *		relative to the Programs group.  For items in the Programs group, 
 *		this parameter should be omitted.
 *
 *	<program name> is the name of the program, and is also used as the name
 *		of the shortcut file itself.
 *
 *	<program path> is the full path name of the program.
 *
 *	<inf file> is the name of the installation inf.
 *
 *	<friendly name> is the text to be used for any message box title.
 *
 * Limitations:
 *
 *	Because some of these strings may contain spaces, the group name, program
 *	name, and program path MUST be enclosed in quotes.  Currently we do not
 *	support strings with quotes in them.
 *
 *	Some of the system functions used in this program are Unicode
 *	specific, so this program will require some modifications to run on
 *	Windows 95.
