Demonstrates how to create a zip where the filename within the .zip is different than the filename that was added from the filesystem.

Note: This example requires Chilkat v11.0.0 or greater.

func chilkatTest() {
    var success: Bool = false

    // This example requires the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    let zip = CkoZip()!

    // Intialize the zip object by calling NewZip.
    success = zip.newZip("myZip.zip")

    // Add a reference to a file on disk to the zip object.
    // (When appending files to a zip, the files are not actually
    // read into memory.  References to the file(s) are added.
    // When WriteZip is called, the referenced files are streamed in
    // and compressed to the .zip.)
    var saveExtraPath: Bool = false
    success = zip.addFile("/temp/a/hamlet.xml", saveExtraPath: saveExtraPath)
    if success == false {
        print("\(zip.lastErrorText!)")
        return
    }

    // The zip object references a single file.
    // Retrieve the entry object...
    let entry = CkoZipEntry()!
    zip.entry(at: 0, entry: entry)

    // Set the entry's filename to anything you want:
    entry.fileName = "somethingElse.xml"

    // Note: Internally, the zip component retains the name of
    // the file referenced.  The current setting of the zip entry's
    // FileName property is stored in the .zip when writing.

    // The zip written here will contain somethingElse.xml
    success = zip.writeAndClose()
    if success != true {
        print("\(zip.lastErrorText!)")
    }
    else {
        print("Zip created!")
    }
