// QuickZip.cs
// ------------------------------------------------------------------
//
// A simple app that creates a zip file, zipping up a files and
// directories specified on the command line.  This application needs to
// be run from the console, in order to specify arguments, but it is
// also a winforms app.
//
// It correctly does the multi-threading to allow smooth UI update.
//
// compile it with:
//      c:\.net3.5\csc.exe /t:exe /debug:full /optimize- /R:System.dll /R:Ionic.Zip.dll
//                                /out:QuickZip.exe QuickZip.cs
