// Mkzip writes a zoneinfo.zip with the content of the current directory

// Usage:
//
//	go run ../../mkzip.go ../../zoneinfo.zip
//

	// Information describing expected zip file content.
	// First, reading the entire content should produce the error ContentErr.
	// Second, if ContentErr==nil, the content should match Content.
	// If content is large, an alternative to setting Content is to set File,
	// which names a file in the testdata/ directory containing the
	// uncompressed expected content.
	// If content is very large, an alternative to setting Content or File
