// Create a toolkit that supports Greenleaf decompressors and ALFile objects.

// C++ SYNOPSIS

// ALToolKit GlDecompressFileTools();
//
// C SYNOPSIS
//
// None, C programmers should use the shortcut helper function
// newALListGlDecompressFileTools() to create an entry list with this
// toolkit.
//
// VB SYNOPSIS
//
// None, VB programmers should use the shortcut helper function
// newALListGlDecompressFileTools() to create an entry list with this
// toolkit.
//
// DELPHI SYNOPSIS
//
// None, Delphi programmers should use the shortcut helper function
// newALListGlDecompressFileTools() to create an entry list with this
// toolkit.
//
// ARGUMENTS
//
// None, we have to get the compression level from the archive, so there
// isn't any point in defining it here.
//
// DESCRIPTION
//
// An ALToolKit is a factory that things in the ALArchive class can use
// to clone new objects. GlDecompressFileTools() creates a toolkit that can
// build Greenleaf decompressors and file objects. If your app is only
// going to be decompressing files, you can use this toolkit to initialize
// your ALEntryList, and avoid linking in a bunch of support for
// ALMemory objects, compressors, and so on.
//
// RETURNS
//
// A new toolkit.

// NAME
//
// newALListGlDecompressFileTools()
//
// PLATFORMS/ENVIRONMENTS
//
// Console Windows PM
// C VB Delphi
//
// SHORT DESCRIPTION
//
// Create an entry list that uses the Greenleaf and ALFile toolkit.
//
// C++ SYNOPSIS
//
// None. C++ programmers can create and manipulate toolkits easily.
// This isn't the case for C/VB/Delphi programmers, so we give them
// a special function.
//
// C SYNOPSIS
//
// #include "arclib.h"
//
// hALEntryList newALListGlDecompressFileTools( hALMonitor monitor );
//
// VB SYNOPSIS
//
// Declare Function newALListGlDecompressFileTools Lib "AL20LW"
// (ByVal monitor&) As Long
//
// DELPHI SYNOPSIS
//
// function newALListGlDecompressFileTools( monitor : hALMonitor ) : hALEntryList;
//
// ARGUMENTS
//
// monitor : A pointer to a monitor that will be used whenever we are
// processing objects in the list.
//
// Note that we have to get the compression level from the archive,
// so there isn't any point in defining it as an argument here.
//
// DESCRIPTION
//
// C++ programmers pass a toolkit argument to the ALEntryList constructor,
// which determines what sort of decompressors and storage objects they are
// expecting to use. C/VB/Delphi programmers can do the same thing as well,
// but it's a little bit harder for them. They have to manually create
// a toolkit, get its handle, then pass that handle to the constructor.
// After that, they need to destroy the toolkit.
//
// As a shortcut way to bypass all that work, we provide this function that
// creates an ALEntryList with the appropriate toolkit.
//
// RETURNS
//
// A handle to the newly created ALEntryList object.
