+####### Using ZipInputStream alone: #######
+
+Zip::ZipInputStream.open("example.zip") {
+  |zis|
+  entry = zis.get_next_entry
+  print "First line of '#{entry.name} (#{entry.size} bytes):  "

+####### Using ZipFile to read the directory of a zip file: #######
+
+zf = Zip::ZipFile.new("example.zip")
+zf.each_with_index {
+  |entry, index|
+  
+  puts "entry #{index} is #{entry.name}, size = #{entry.size}, compressed size = #{entry.compressed_size}"
+  # use zf.get_input_stream(entry) to get a ZipInputStream for the entry
+  # entry can be the ZipEntry object or any object which has a to_s method that
+  # returns the name of the entry.

+####### Using ZipOutputStream to write a zip file: #######
+
+Zip::ZipOutputStream.open("exampleout.zip") {
+  |zos|

+  zos.puts "Hello hello hello hello hello hello hello hello hello"

+
+  # Use rubyzip or your zip client of choice to verify
+  # the contents of exampleout.zip
+}
+
+####### Using ZipFile to change a zip file: #######
+
+Zip::ZipFile.open("exampleout.zip") {
+  |zf|
+  zf.add("thisFile.rb", "example.rb")
+  zf.rename("thisFile.rb", "ILikeThisName.rb")

+}
+
+# Lets check
+Zip::ZipFile.open("exampleout.zip") {
+  |zf|
+  puts "Changed zip file contains: #{zf.entries.join(', ')}"
+  zf.remove("Again")
+  puts "Without 'Again': #{zf.entries.join(', ')}"
+}
