// This is a the source module that implements the stuff for saving to a
// self-extracting Zip archive.
//
// ZipFile is set up as a "partial class" - defined in multiple .cs source modules.
// This is one of the source modules for the ZipFile class.
//
// Here's the design: The self-extracting zip file is just a regular managed EXE
// file, with embedded resources.  The managed code logic instantiates a ZipFile, and
// then extracts each entry.  The embedded resources include the zip archive content,
// as well as the Zip library itself.  The latter is required so that self-extracting
// can work on any machine, whether or not it has the DotNetZip library installed on
// it.
//
// What we need to do is create the animal I just described, within a method on the
// ZipFile class.  This source module provides that capability. The method is
// SaveSelfExtractor().
//
// The way the method works: it uses the programmatic interface to the csc.exe
// compiler, Microsoft.CSharp.CSharpCodeProvider, to compile "boilerplate"
// extraction logic into a new assembly.  As part of that compile, we embed within
// that assembly the zip archive itself, as well as the Zip library.
//
// Therefore we need to first save to a temporary zip file, then produce the exe.
//
// There are a few twists.
//
// The Visual Studio Project structure is a little weird.  There are code files
// that ARE NOT compiled during a normal build of the VS Solution.  They are
// marked as embedded resources.  These are the various "boilerplate" modules that
// are used in the self-extractor. These modules are: WinFormsSelfExtractorStub.cs
// WinFormsSelfExtractorStub.Designer.cs CommandLineSelfExtractorStub.cs
// PasswordDialog.cs PasswordDialog.Designer.cs
//
// At design time, if you want to modify the way the GUI looks, you have to
// mark those modules to have a "compile" build action.  Then tweak em, test,
// etc.  Then again mark them as "Embedded resource".
