// NAME

//  PkDecompressTools()
//
// PLATFORMS/ENVIRONMENTS
//
//  Console  Windows  PM
//  C++  C  VB  Delphi
//
// SHORT DESCRIPTION
//
//  Create a toolkit that supports PKWare decompressors.
//
// C++ SYNOPSIS
//
//  #include "arclib.h"
//
//  ALToolKit PkDecompressTools();
//
// C SYNOPSIS
//
//  None, C programmers should use the shortcut helper function
//  newALPkDecompressTools() to create an entry list with this toolkit.
//
// VB SYNOPSIS
//
//  None, VB programmers should use the shortcut helper function
//  newALPkDecompressTools() to create an entry list with this toolkit.
//
// DELPHI SYNOPSIS
//
//  None, Delphi programmers should use the shortcut helper function
//  newALPkDecompressTools() to create an entry list with this toolkit.
//
// ARGUMENTS
//
//  None.
//
// DESCRIPTION
//
//  An ALToolKit is a factory that things in the ALArchive class can use
//  to clone new objects.  PkDecompressTools() creates a toolkit that can
//  build PKWare decompressors.  If your app is only going to be
//  decompressing some type of objects, you can use the toolkit returned
//  by this function in your ALEntryList, and avoid linking in support for
//  compression objects.
//
//  This toolkit will clone ALFile() and ALMemory() objects.  If you don't
//  want to support ALMemory objects, try PkDecompressFileTools().
//
// RETURNS
//
//  A new toolkit.  Note that this isn't a pointer, but rather a copy of
//  a new toolkit.  Usually this is copied into an existing toolkit.

// NAME
//
//  newALListPkDecompressTools()
//
// PLATFORMS/ENVIRONMENTS
//
//  Console  Windows  PM
//  C  VB  Delphi
//
// SHORT DESCRIPTION
//
//  Create an entry list that uses the PKWare decompressors 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
//  this special function.
//
// C SYNOPSIS
//
//  #include "arclib.h"
//
//  hALEntryList newALListPkDecompressTools( hALMonitor monitor );
//
// VB SYNOPSIS
//
//  Declare Function newALListPkDecompressTools Lib "AL20LW"
//    (ByVal monitor&) As Long
//
// DELPHI SYNOPSIS
//
//  function newALListPkDecompressTools( monitor : hALMonitor ) : hALEntryList;
//
// ARGUMENTS
//
//  monitor : A pointer to a monitor that will be used whenever we are
//            processing objects in the list.
//
// DESCRIPTION
//
// C++ programmers pass a toolkit argument to the ALEntryList constructor,
// which determines what sort of compressors 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.
