unit %ModuleIdent;

//
//  This unit contains the basics necessary for an NSE ShellHandler that does not use the IDEs design time
// capabilities.  It is created automaticlly when a new EasyNSE project is created.  It is necessary to create
// Shell Handler components dynamically and assign the properties/events manually, then register them with the
// global FactoryManager.  There are a few things to remember though.
//
//  1) If you change the names of the DataModule or the Factory Manager you must 
//       reflect those changes in the function InitializeLibrary below manually.
//
//  2) Do not add more TEasyFactoryManager objects to the DataModule.
//
//  3) As Explorer (or other applications that use the shell interfaces) calls to obtain an
//     interface EasyNSE will create a new copy if the object that implements that particular
//     handler.  
//
//  4) Be Careful with global resources.  There can be numerous objects for a handler created and active
//     at the same time that are in different threads.
//
//  5) Be Careful as the objects could also be in different processes so any global variables will
//     need to be reinitialized when the DLL is loaded in a new process. 
//
//  Replace the xxxxxHandler units in the "uses" clause below if using the "EasyIncludeHandler.inc" file in
//  the $(EASYNSE)\Include folder when trying to reduce the DLL size.  These would automaticlly be inserted
//  below but the IDE will strip out the conditional defined when adding or removing DataModules so it must
//  be done manually..... sorry.
//
//  Replace this in the uses clause:
//
//  EasyQueryInfoHandler,
//  EasyPropertySheetHandler,
//  EasyThumbnailHandler,
//  EasyContextMenuHandler,
//  EasyDragDropHandler,
//  EasyColumnHandler,
//  EasyCopyHookHandler,
//  EasyIconHandler,
//  EasyDropHandler,
//  EasyDataHandler,
//  EasyIconOverlayHandler,
//  EasyNamespaceHandler,
//
