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

CkoTar *tar = [[CkoTar alloc] init];

// The TAR component will produce a  GNU tar 1.13.x format
// archive by default.
// It is also possible to create PAX -- POSIX 1003.1-2001 format
// or USTAR -- POSIX 1003.1-1988 format.
// Set the WriteFormat property to "gnu", "pax", or "ustar" to
// choose the output TAR format:
tar.WriteFormat = @"gnu";

// Add a directory tree to be included in the output TAR archive:
BOOL success = [tar AddDirRoot: @"/Users/chilkat/temp/abc123"];
if (success != YES) {
    NSLog(@"%@",tar.LastErrorText);
    return;
}

// Create the compressed TAR archive.
// Note: You may use UNC paths, absolute, or relative paths.
success = [tar WriteTarGz: @"/Users/chilkat/testData/tar/abc123.tgz"];
if (success != YES) {
    NSLog(@"%@",tar.LastErrorText);
    return;
}

NSLog(@"%@",@"Success.");
